Parent page: Capturing Your Design Idea as a Schematic
The heart of any electronics design is the components. The component that you ultimately solder onto the board needs to be represented, or modeled, in each design domain as a symbol on the schematic, as a SPICE model in the simulator, as a footprint on the board, and as a 3D STEP model in the file you hand off to the mechanical designer.
Altium Designer's Components panel provides a powerful interface that you can use to interact with all your components - both Workspace and non-Workspace. You can search for the required component by specifying the category and using straightforward search mode, by entering a query (a full or partial component name, value, etc.) in the search field. Additionally, for your Workspace components, the panel provides a filter-based parametric (faceted) search capability for specifying target component parameters. The panel also offers options to edit a Workspace component through the Component Editor in its Single Component Editing mode, view the component in its source Workspace, and perform component management functions such as component creation and cloning, or editing the selected component's Part Choices and Type. A component can be placed on the schematic by dragging it or using the Place command from the component's right-click menu.
And while you can of course create your own components, Altium Designer provides a powerful Manufacturer Part Search panel that can be used to search for real-world manufactured parts. If you have a Workspace, you can save those parts in that Workspace, and then access them through the Components panel. This process involves creating a new Workspace component - using the Component Editor in its Single Component Editing mode - and saving to your Workspace.
The Components panel provides direct access to available Workspace components, and database and file-based library components in Altium Designer.
The panel sources components from a connected Workspace and any open or installed libraries. The panel offers full details of the selected component (Parameters, Models, Part Choices, Supplier data, etc.), component comparison, and for Workspace components, a filter-based parametric search capability for specifying target component parameters.
The Components panel in its normal mode
The Components panel in its compact mode
The Components panel uses the basic search engine functionality and view that is applied in the Manufacturer Part Search panel. While the Manufacturer Part Search panel harnesses the Altium Parts Provider service and focuses on the component manufacturer and supplier data searches, the Components panel is populated with ready-to-place components from your connected Workspace and database and file-based library sources.
Components Panel Access
To open the Components panel, select View » Panels » Components from the main menus or the Components option from the button menu at the lower right of the main screen. Using a responsive design configuration, the panel layout will dynamically adapt between full-screen normal mode () and its compact mode () where the Categories/Filters options collapse to menus.
From within a schematic document, use the P, P keyboard shortcut to open the Components panel. You can also use the Place » Part command from the main menus, the Place » Part command from the right-click menu of the schematic editor design space, or the Part button () on the Active Bar.
From within a PCB document, use the P, C keyboard shortcut to open the Components panel. You can also use the Place » Component command from the main menus, the Place » Component command from the right-click menu of the PCB editor design space, or the Component command () on the Active Bar.
At the first launch of the Components panel in the current Altium Designer session, the following controls are available when connected to a Workspace:

Grouping the list by column data – right-click in a column header, select the Enable Columns Grouping option then drag a column header (e.g.,
Footprint) into the grouping space at the top of the list. The list entries will be collected under each unique parameter (e.g., type of footprint) from the specified grouping column.
- Filtering the listing by a specific column entry – select in a column header to display a list of its unique parameter entries then select an entry to constrain the listed components to those that include the specified parameter (e.g., a footprint type code). Select the All option to reset the filter. Select (Custom) to open the Filter Editor dialog in order to further refine the filtering in the selected column.
There are various manners in which you may display the contents within the Components panel. When right-clicking on the names of each column (Name, Description, Footprint) you may select from the following options, depending on how you wish to display the components:
- Best Fit – merges the contents from the Name and Descriptions columns together so they are closely placed, with no excess room between each column.
- Best Fit All Columns – merges the contents from all columns together so they are closely placed, with no excess room between each column.
- Clear Sorting – used to undo the sorting of columns.
- Enable Columns Grouping – allows you to drag column headers by a specific column, allowing you to change the order of the Name, Description, and Footprint columns.
- Select Columns – opens the Select Columns dialog, which allows you to select other columns you would like visible in this section.
- Apply Column Visibility to Child Categories – in cases when the selected category has a child category, use this command to ensure the possibility of pushing column visibility settings from parent categories to child categories. This command is available only when a child category exists.
Component Search and Functions
Searching for components
To search for available components in the Components panel, enter a phrase in the Search field and/or use the panel's Categories and Filters selections to narrow the component listing to your specific needs. Filters are supported for Workspace components only, and as in the Manufacturer Part Search panel, the Components panel supports unit-aware (text to number) search filters. The search functionality prioritizes results according to the entered search criteria.
The Search function allows you to select then edit or add to an active Search string.
Click the 'active' search string to enter it into the Search field. You can reuse or edit that search from the Search field.
The Find Similar Components dialog accessed by right-clicking on a listed component, then selecting Find Similar Components, provides the possibility to define search preferences based on the selected component.
The final search results will depend on the selected component type, be it Workspace or non-Workspace components, and your Workspace connection status. For example, Workspace components will often display more parameters than a non-Workspace component. To specifically gather components and parameters that are the same or different from the one selected, the drop-downs may be utilized to select Same, Any, or Different choices.
The dialog is divided into three primary sections that list the attributes of the chosen component, sectioned off by Component, Parameters, and Models.
The grid of attributes for the chosen component is divided into three columns:
- OK - click to save your selected criteria and close the dialog.
- Apply - click to to test your search criteria to yield the desired results without closing the dialog.
A selected component is placed on a schematic by dragging and dropping, selecting Place from its right-click context menu, using the button in the Details pane, double-clicking on the entry for the required component, or using the Enter hotkey.
Placing a Multi-part Component
If the component being placed has multiple parts, the part selected under the symbol preview image in the Models region of the panel will be initially placed.
Once a part of a multi-part component is placed, it can be changed to another part of this component using the Part drop-down in the Properties panel when the part is selected, or it can be switched to the next available part using Edit » Increment Part Number command from the main menus or the Part Actions » Increment Part Number command from the part's right-click menu.
Filtering Through Components
When viewing Workspace components, the Filters pane is populated by selected filter options based on the current search and available parameters. Parametric filtering of the listed components provides further options for locating a specific component or type of component. Open the Filters pane from the button above the Categories pane. In the panel's compact mode, click the button to pop out the Filters as a panel extension.
Note that filters are only supported for Workspace components. Use the Filter Search field within the pane to find a specific parameter filter.
The panel Filters options can be tailored to your needs by selecting particular parameter types as Favorites, which then shift to the top of the list for the current component Category. Hover to the right of a parameter filter’s name and click the icon to set the filter as a Favorite. Favorite filter settings apply to and are saved for individual component Categories.
For Workspace components, the right-click menu offers options to edit the component through the Component Editor (Edit) and perform component management functions such as component creation and cloning, or editing the selected component's Part Choices and Type (Operations).
Additional information options in the component Details pane include: viewing a model image, viewing online datasheets (References), live Supplier information (Part Choices), seeing where the part has been used in Workspace projects and Managed Sheets (Where Used), and through the right-click menu, the ability to copy selected or all component parameter data (technical details) in a tab-delimited format, and resetting parameters marked as favorites to the five default parameters.
When browsing the components in a connected Altium 365 Workspace and if any issues regarding the health of the selected component are found, an indication of it will be presented by the (for errors) or (for fatal errors) icon in the Component issues line above the component parameter list. The number at the right of the icon indicates the number of found issues. Click the down arrow at the right of the number to see the short descriptions of the issues.
An example of library health issues found.
You may use the custom filtering feature to further refine filtering in the Components panel. The feature is available by clicking the filter () icon in the header, then selecting
(Custom). This will open the Filter Editor dialog, which allows you to define the condition, operator, value, operator type, etc., for which you want to filter results.
Select a Workspace component in the Components panel to view information about where the latest revision of it is currently used in the Where Used region. The region provides quick-filter information for:
- Projects – the Workspace projects in which the component has been used. Information is only presented once the project has been saved to the Workspace.
- Managed Sheets – the managed schematic sheets on which the component has been used.
- Reuse Blocks - the Reuse Blocks stored as part of a connected Workspace's library.
Component Data Caching
When using the Components panel, the data for Workspace components are cached to the local machine from the Workspace. This provides an offline access mode for Workspace components when Altium Designer is not connected to the Workspace, and therefore allows normal component browsing and placement, etc.
At the first launch of the Components panel in the current Altium Designer session, a warning will be shown in the panel when in offline mode, along with controls to keep using the cached component data or to clear the cache.
Click the Use Cached Data to use the cached components. This condition will be indicated by the Offline mode – cached data is being used warning text in the lower bar of the panel’s component list pane. Note that Filters are not enabled in this mode.
The cache builds up component data over time and may be cleared at any time (for all Workspaces) using the Clear Cache option that is available under Known Servers in the Data Management – Servers page of the Preferences dialog.
Part Choices List
Edit the Part Choices List associated with a Workspace component by selecting the Operations » Create/Edit Part Choices option from the entry’s right-click menu.
Use the following Edit Part Choices dialog’s button to open the Add Part Choices dialog, which will automatically search for part manufacturers by the selected component's
Name parameter. Deselect the predefined search term to manually search for alternatives – functionally, the dialog is a modal version of the Manufacturer Part Search panel.
Part Choice entries in the list can be ranked by selecting an appropriate star icon level, where the list will automatically be reordered with the highest-ranked manufacturer choice at the top.
Part Choices are carried with the component wherever its data is applied, such as in a Schematic design, BOM document, Output Report, and so on.
Components Panel Right-click Menu
The right-click pop-up menu for the panel provides the following commands:
- Place [ComponentName/FootprintName/SimulationModelName] – use to place the currently selected component or simulation model onto the active schematic document or currently selected footprint onto the active PCB document.
- Find Similar Components – use to open the Find Similar Components dialog to set up search criteria to find components similar to the selected component.
- Navigate to [ComponentName] – use to open the chosen Workspace component in the Explorer panel, where you can access detailed Item information and manage the revision and lifecycle settings for the Items, as well as where-used and supply chain detail, amongst other options.
- Edit – click to edit the selected Workspace component(s) through the Component Editor (in its Single Component Editing or Batch Component Editing mode) or selected domain model (symbol, footprint, or simulation model) in its editor. If the current component type is different from the template that is currently being used, the will open. Use the dialog to change the component type of the selected component.

- Create – click to open the Create new component dialog to select the type of component when adding a new component.
- Delete – click to delete the selected component(s) from your connected Workspace.
- Operations – use to access a drop-down menu of additional functions for Workspace components as described below.
- Refresh – click to quickly refresh the panel. The current component selection will be saved.
The Compare feature allows you to compare the parameters of two selected components (parts). This feature is accessed by selecting two components in the grid region with the icon enabled (blue). The Selected Component Details region opens to the right of the grid region. The upper region (region 1 in the image below) displays an image, the name, description, and price of the selected components side-by-side. Click the Datasheet button to open the manufacturer's datasheet (if available) for the associated component. Click the Place button to place the component in the design space. The component will appear floating in the design space; click to place the component in the desired location. You can continue to place additional components or right-click or Esc to leave placement mode and return to the Components panel.
The lower region (region 2 in the image below) displays a side-by-side view of the components' parameters, with differences highlighted in red text for easy comparison.
The Compare feature is also available when the Components panel is in compact mode, though it works a tad differently. This feature is accessed by selecting two components in the grid region. The Selected Component Details region opens below the grid region. The upper region displays the name, price, and view of the components' parameters, with differences highlighted in red text for easy comparison. The lower region displays a side-by-side view of the components' Symbols and Models.
Editing Component Symbols and Footprints
The symbol and footprint of a given component can be hidden within the Models section of the Details pane, which is accessed by clicking on the upper right. Once hidden, the symbol and footprint will be replaced with clickable links that revert the hidden items to their original view. Also included is the ability to scale the size of the displayed models. For both the symbols and footprints, click and drag the lower perimeter of the model area to resize the image.
For a Schematic Library (*
.SchLib) file being browsed in the Components panel, the symbol and footprint of the selected component can be edited using the button at the bottom-right of the model preview.
The ability to edit a footprint is made available when accessing the Components, as long as valid and linked footprints are already present.
Component Selection Dialogs
The search engine and view used in the Components panel is also applied in other Altium Designer applications where a component choice is made. The component search functionality is included in these (modal) dialogs, along with an OK confirmation button and minor variations in the available action commands. The dialog is typically called Component Search.
Accessing and Placing Generic Components
To expedite the process of laying out the early stages of a design, the concept of standard, basic Generic Components is available. Generic components can quickly be placed in a design without the need to find and choose a specific manufacturer part from the available component sources. Generic components are intended as placeholders that are easily replaced by a suitable component later in the design process – they also can be considered as virtual or parametric components.
When Altium Designer is connected to a Workspace, the available Generic Components can be accessed from the panel where they are exposed when the All option is selected in the Categories pane – or from the top drop-down menu when the panel is in its compact mode. Click on the button within a Generic Component tile to attach the component to the cursor for placement in the active schematic document. Selecting the tile itself will open that component type category in the panel.
Placing a Generic Component from the Components panel
Select a placed Generic Component to access its properties in the Properties panel, which provides only those settings and parameters that are relevant to this type of component. The available parameters are determined by the related Component Template (
Resistors in the example shown here). Parameter values can be manually entered, or selected from a drop-down menu list that offers values sourced from all the available components of that type.
Specifying parameters of a generic component – selecting parameter values from the drop-downs.
Specifying parameters of a generic component – the result.
Support for Jumper Components
Jumpers, also referred to as wire links, allow you to replace routing with a Jumper component, which is often an essential ingredient to successfully designing a single-sided board. Altium Designer supports use of jumper components through a special component type of
While you can start by placing the Jumper footprints directly onto the PCB, a suggested workflow starts at the schematic. To learn more, refer to the Working with Jumper Components page.
Manufacturer Part Search Panel
The fundamental design task of searching for and choosing the most suitable component parts for PCB designs can be performed in a single, advanced panel available from within Altium Designer – the Manufacturer Part Search panel. As a replacement for the Part Search panel, the Manufacturer Part Search panel offers a sophisticated search feature based on categories and parametric filtering that allows you to zero in on the exact manufactured components you need, and also select a preferred supplier of that physical part based on cost and availability.
A selected manufactured part can be saved to a connected Workspace or downloaded as a library, or its parameters and datasheets added to an existing part in the design space. The preferred supplier(s) of that manufactured part may also be selected and added, as Supplier Link parameters, to an existing design part. Saving to your own connected Workspace involves creating a new component using the Component Editor in its Single Component Editing mode, pre-filled with information from the searched part.
Manufacturer Part Search Panel Access
To open the Manufacturer Part Search panel, select View » Panels » Manufacturer Part Search from the main menu or the Manufacturer Part Search option from the button menu at the lower right of the main screen. When vertically docked, use the to toggle the panel layout between full screen (wide) mode and its narrow docked mode.
The Manufacturer Part Search panel in its normal mode
The Manufacturer Part Search panel in its compact mode
The panel harnesses the manufacturer and supplier data resources of the Altium Parts Provider service to source the most pertinent and up-to-date component data. A selected manufactured part can be saved to a connected Workspace or downloaded as a file-based library, or its parameters and datasheets added to an existing part in the design space. The preferred supplier(s) of that manufactured part may also be selected and added, as Supplier Link parameters, to an existing design part.
If you are not signed in to your Altium account, you can first sign in or register from this panel. Clicking Sign in will provide access to the Sign In dialog from which you can sign in to your Altium account using your Altium account credentials (username and password). If you have not yet created an Altium account, click register to open the browser-based interface as presented through Altium 365 where you can register for Altium 365 or view and make changes to your Workspace if you already own one.
Use the controls in the panel to sign in to your Altium account or to register a new one.
Manufacturer and Supplier Data
The panel’s advanced search engine allows it to be used in a straightforward search mode, by entering a query in the main Search field, or in its advanced parametric mode by progressively refining the search criteria using component type category choices and smart Filters – or indeed, by using both capabilities together.
Click the icon to show or hide the Filters pane, and use the selection options in the categories drop-down menu () to restrict the list to a particular component type.
When using the parametric search options, which is ideal for researching suitable manufactured parts for a design, the panel's filter options will dynamically adapt to the most relevant parameter choices based on the existing category/filters selections. This allows you to quickly narrow the listed choices to the most suitable manufactured parts, which in turn are ordered by a combination of model availability, supplier stocks and price. Note that multiple options may be selected for a given (checkbox-based) filter attribute, and the filters also include unit-aware (text to number) search options for specifying a range of acceptable parameter values.
Use the provided categories and filters to quickly refine the component list.
The currently selected filter options are shown above the parts list and may be removed (via their associated X icon) to modify the active search filtering. Similarly, individual choices in the Filters list may be removed by unchecking an entry or deselecting an option button.
A selected manufacturer part in the list is summarized by its column data, where all available parameter columns are active by default. Within the component listing, the content that is included may be managed by:
Based on the data of any part in the panel, a new component can be created in your connected Workspace – that effectively means that any listed component can be saved to your Workspace. Use one of the following controls to save a component to your connected Workspace:
- the button;
- the Save to My Workspace (when connected to an Altium 365 Workspace) / Save to My Server (when connected to an Altium Enterprise Workspace) command of the button menu;
- the Save to My Workspace / Save to My Server command of the component entry's right-click menu;
- the button that appears on the component entry's image when the mouse cursor hovers over the entry.
Parts with associated models are ready for use in designs and may be attained by downloading the selected component(s) to a zipped Integrated Library Package – select the Download as File Library command from the button menu or the component entry's right-click menu.
Parts located through the panel are saved to your Workspace and then reused in designs as Workspace Library components. Alternatively, a part may be placed in an active design directly from the panel using the Place option in the right-click menu or button menu. Note that with this approach, however, the placed component’s data source will be the Altium Content Vault rather than your own Workspace.
Each part entry in the list also includes a link to the online manufacturer's data, and a link to a tabular list of supplier choices – again ordered by their price/availability suitability.
The panel provides supplier data for available components.
The supplier entries provide a snapshot of the current (live) stock level, pricing and supplier part number. To view the supplier data, click the SPNs link located in the Manufacturer Part column after selecting a part. Right-click on a supplier cell to add the associated Supplier Link to a component part in the schematic editor, via the mouse cursor (Add Supplier Link to Part). The alternative Add Supplier Link and Parameters to Part option also adds all parameters for that manufacturer component to the schematic part.
When a Schematic Library is the active document, drag and drop a Supplier cell onto an entry in the SCH Library panel, or onto the editor space, to add that component Supplier Link. Alternatively, right-click on the Supplier cell to add the link and/or the part parameters to the component selected in the SCH Library panel, or choose the Import Into option to add that component data as a new library entry.
Manufacturer Part Search Panel Right-click Menu
- Save to My Workspace / Save to My Server – use to save the selected component to a connected Workspace.
- Download as File Library – use to download the selected component(s) to a zipped Integrated Library Package. Select multiple part entries to download those parts in a single session.
- Place - use to place a part in the active design.
- Submit Request – use to access the active part request process definitions. If no active process definitions are available for the Part Requests process theme, the Submit Request button will be grayed out (not available). You may need to sign out of the Workspace and back in again or restart Altium Designer to refresh. Note that this option is only available with Altium Designer Enterprise Subscription (and connected to either an Altium 365 Workspace, or an Enterprise Server Workspace).
- Add Supplier Link To – use to add the selected Supplier Link to a component part in the schematic editor (when a schematic document is currently active) or to the component currently selected in the SCH Library panel (when a schematic library document is currently active).
- Add Supplier Link And Parameters To – use to add the selected Supplier Link and all parameters for that manufacturer component to a component part in the schematic editor (when a schematic document is currently active) or to the component currently selected in the SCH Library panel (when a schematic library document is currently active).

- Preferences – click to open the Data Management - Parts Providers page of the Preferences dialog to configure parts providers.
Full details of the selected manufacturer part, including models if available, are presented in the panel’s Details section pane – on the right in the panel’s full-screen mode. Use the panel's button (top right) to toggle the visibility of the Details pane.
The information and options presented in this section depend on the available component data, where a part may be saved to your connected Workspace, saved as an integrated library package or placed in the design (the button menu), and datasheets viewed from the menu or from the pane's Datasheets list.
The drop-down menu offers options to save the component to a connected Workspace (via the Create new component dialog and Component Editor in its Single Component Editing mode) or download the component locally as an Integrated Library Package in a zip archive. Alternatively, a new Part Request can be created.
Further options in the part Details section include:
- Add selected parameters to a schematic component part using mouse cursor targeting (drag and drop, or from right-click menu).
- Copy all or selected parameter data as a tab delimited text list – right-click menu options.
- View alternative part suggestions in a list ordered by a suitability rating (Alternatives), where each entry links to its online part data.
- Select multiple component entries to enable the data comparison feature, where the parameter differences between the selected parts are highlighted as red text.
Component replacement is often performed when a part is obsolete or no longer recommended. The Alternatives region of the Manufacturer Part Search panel provides a list of available alternatives for the currently selected manufacturer part. The number next to an alternative part indicates the confidence score of this part as a replacement for the selected part.
With Altium Designer Standard Subscription, community-based data for part alternatives are provided, with the confidence scores aggregated from distributors' data. With Altium Designer Pro Subscription or Altium Designer Enterprise Subscription, advanced part alternative data is provided by IHS Markit®. In this case, the confidence score reflects the following:
- 9 – an alternative identified by component engineers through detailed analysis of device characteristics as having identical form, fit, and functionality.
- 8 – an alternative identified as having identical form, fit, and functionality based on internal rules.
- 6 – an alternative that is functionally equivalent, meaning that it has the same functionality but may have a different form or fit.
- 2 – an alternative that has similar functionality but may have a different form or fit.
You can open a drop-down menu at the right of an alternative part's MPN to access the following commands:
- Open in Manufacturer Part Search – uses the Manufacturer Part Number and Manufacturer Name as a search request in the Manufacturer Part Search panel so you can further investigate this alternative part.
- Open in Octopart – opens the Octopart site, providing detailed information on that manufacturer part.
The data of a found alternative (the manufacturer part number and the manufacturer name) can be copied from the panel (which might be helpful if you need, for example, to add this alternative part as a part choice for a component). Hover the cursor over the MPN or manufacturer name of an alternative part and click the icon that appears at the right of the MPN.
The search engine behind the Manufacturer Part Search panel will source parts data from the Altium Parts Provider service and where possible, access matching schematic, PCB and Sim models from the Altium Content Vault. The match between a part listed in the Manufacturer Part Search panel and models from the content server is based on the manufacturer name and the manufacturer part number. In a Workspace, this is determined by the Part Choices associated with a Workspace library component.
In the example shown below, models from the Altium Content Vault are sourced by the panel because that particular LED component can be found in the content server, based on its Part Choices entry. All other data is sourced live from the Altium Parts Provider, giving you the latest Manufacturer and Supplier information for the selected component.
The selected component has assigned models as indicated by its associated symbol.
When a component part is saved to a Workspace/integrated library from the Manufacturer Part Search panel, the component data (both models and parameters) are sourced from the Altium Content Vault. In practice, the found component is matched to an Altium component, which will include its parameters when placed.
As an adjunct to this, the panel offers a rich source of parameter data with each part entry, courtesy of the Altium Parts Provider service – see the parameter list in the selected part Details section. These parameters represent the current manufacturer data for that part, and therefore relevant, up-to-date information that can be added to a component in a Workspace/integrated library or board design.
For example, use the right-click menu in the panel's parameters list to add selected parameters to a schematic component, or choose the Add Supplier Link and Parameters to Part option (as outlined above) when adding supplier data to a component. Note that parameters sourced from the panel are added to the schematic component's existing parameters.
Part Search dialogs
The search engine and view used in the Manufacturer Part Search panel are also applied in other Altium Designer applications where component data is sourced. The Part Search functionality is included in these (modal) dialogs, along with an OK confirmation button and minor variations in the available action commands.
Manufacturer Part Choices:
The Compare feature allows you to compare the parameters of two selected parts (components). This feature is accessed by selecting two parts in the grid region with the icon enabled (blue). The Selected Part Details region opens to the right of the grid region. The upper region (region 1 in the image below) displays the selected parts side-by-side. Click the Datasheet button to open the manufacturer's datasheet (if available) for the associated component.
The lower region (region 2 in the image below) displays a side-by-side view of the components' parameters, with differences highlighted in red text for easy comparison.
