Keep it running.

Part numbers change. Manufacturers discontinue products. Protonym helps connect old information with current options.

From a reference to a clearer decision.

Start with a part number, machine model, photo, nameplate, or drawing. Protonym is being built to help you identify components, research replacements, and connect with suppliers.

This first version introduces the search and request workflows. Search uses sourced catalog records. Identification and quote requests are saved for research; automatic identification and compatibility decisions are not offered.
