Sizing the PCB Footprint and Mating Half
The 2-292173-5: The mating half is a TE CT series receptacle housing (base number 292173) with crimp terminals. Derate for higher ambient temperatures per the CT series derating curve.
The housing is moulded from polyamide 6T (PA6T) with glass fill, rated UL94 V-0. Tin is adequate for environments without corrosive gases or frequent disconnect cycles — the contact resistance stays stable through the rated life.
