Replace Component (File-based)

This document is no longer available beyond version 22. Information can now be found here: Updating and Replacing Components from a Library for version 24



The Replace Component dialog provides direct access to all available Workspace-based managed components and file-based library components. The dialog offers full details of the selected component (Parameters, Models, Part Choices, Supplier data, etc.,), component comparison, and for Managed Components, a filter-based parametric search capability for specifying target component parameters.

The dialog 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 dialog is populated with ready-to-place components from your managed content server and file-based library sources.


The dialog is accessed in the following ways:

  • With a component selected in a managed project, from the General tab of the Properties panel, select the required source from the Source drop-down in the Properties region, then click  in the Design Item ID field. 
  • From the schematic or PCB editor of a managed project, enable Alternate Part in the Edit Component Variation dialog (accessed by clicking in the Component Variation column of Variant Management dialog) then click the Choose button.
  • For the Variant Manager, select Alternate Part from a component's drop-down in the Variant Manager grid area.
  • From an ActiveBOM document (*.BomDoc), right-click on a component then choose Operations » Add Alternative Item.
When the dialog is accessed from the ActiveBOM, the title of the dialog (in the banner) will be Add Alternative Item.
