The Edit Component Variation dialog with Fitted selected, Alternate Part selected with Use server Component unchecked, and Alternate Part selected with Use server Component checked.
The Edit Component Variation dialog provides controls to specify the variation of a component. Variants that use any of these types of variations are all referred to as Assembly Variants since they only impact the assembly process.
The dialog is accessed by clicking in the Component Variation column (available after a variant is added) of the Components region in the Variant Management dialog, or by right-clicking on a component with a defined variant, while in compiled view mode, then choosing Part Actions » Choose Alternate Part.
Fitted - the original component as used in the base design is also fitted/used in this variant of that design. For a newly added variant, all components are fitted by default. The cell entry for a fitted component appears blank/empty.
Not Fitted - the original component as used in the base design is not fitted/used in this variant of that design. The entry for a component that is specified as being not fitted appears with the entry Not Fitted.
Alternate Part - this is the strongest form of variation. It allows you to substitute the original component as used in the base design with a completely different component in this variant of that design.
If Alternate Part is selected, the dialog will expand to include controls to browse and locate the required component. This can be a server-based component (the Link to Vault Component region opens) or other component storage models supported in Altium Designer, such as independent libraries and database libraries (the Link to Library Component region opens).
Use server Component - check this box to use a component from a server. Uncheck this box to use a library component. The coordinating Link to region will appear.
