It is a female contact designed for use with the matching Multimate III+ pin contacts and compatible housings. The stamped construction keeps the per-unit cost low for high-volume harness builds while maintaining reliable electrical performance.
202237-4 vs 202237-1 — What's the Difference?
The 202237-4 and 202237-1 are both Multimate III+ stamped socket contacts with the same brass material, solder eyelet termination, and Tin-Lead plating. The difference is in the contact finish thickness: the 202237-4 carries 50.0µin (1.27µm) of Tin-Lead, while the 202237-1 is plated with 30.0µin (0.76µm). For applications requiring higher corrosion resistance or more mating cycles, the thicker 50.0µin plating on the 202237-4 is the better choice.
Compatible Housings and Mating
This socket contact mates with the Multimate III+ pin contacts (such as the 202237-1 or 202237-2 in pin form) and fits into the standard Multimate III+ housings — typically the CPC (Circular Plastic Connector) or similar rectangular connector shells that accept size 16 contacts. The solder eyelet termination allows for a secure, permanent connection to a wire or PCB pad before the contact is inserted into the housing. Always verify the housing part number against the contact size and series to ensure proper retention and sealing.
