In a production harness or a field-replaceable module, the tin interface wears with each mate — budget for 25–50 mating cycles before contact resistance starts to drift.
Mates with any KK254-series crimp receptacle housing (e.g., Molex 50-57-9408 for 10 positions) that accepts 22–30 AWG wire. The unshrouded pins also accept standard 0.025" square-post IDC connectors.
This unshrouded header mates with a KK254 crimp receptacle housing from the same series (4030). The push-pull retention is suitable for applications without continuous vibration.
Yes, it is ROHS3 Compliant.
