Manufacturer Part Number (MPN)
A Manufacturer Part Number (MPN) is an identifier assigned by a manufacturer to a specific component or product. It distinguishes that part’s specifications and configuration from other parts in the manufacturer’s range. MPNs help engineering and procurement teams identify, source, and compare components, supporting accurate pricing analysis, lifecycle tracking, supply risk assessment, and evaluation of alternatives.
