This application discloses a computing system implementing part number consolidation functionality can determine part numbers available for assignment to components represented in a printed circuit board assembly design based on electrical or physical characteristics associated with the components. The computing system can compare the available part numbers for the components to each other to determine a commonality among the available part numbers for a plurality of the components. The computing system also can compare the available part numbers for the components to part numbers associated with a different product to be manufactured at one or more manufacturing facilities. The computing system can assign one or more of the available part numbers to the components based, at least in part, on the commonality among the available part numbers, which consolidates the assigned part numbers to the components in the printed circuit board assembly design.
