Created: July 28, 2015 | Updated: June 16, 2017


The Edit Component Variation dialog with Fitted selected, Alternate Part with Use Vault Component checked and Alternate Part with Use Vault Component unchecked)


This dialog allows the user 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.

See Design Variants for more information about Variants.


To access this dialog, in the Variant Management dialog, click the  button in the Component Variation column of the Components region.


  • 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 vault-based component (Link to Vault Component region opens) or other component storage models supported in Altium Designer, such as independant libraries and database libraries (Link to Library Component region opens).
