Pitch, Plating, and Current Ceiling
Tin is a workable choice for moderate mating cycles (50–100) in a dry indoor environment; it will wear faster than gold if the connector is cycled frequently in a dusty or corrosive atmosphere.
This header mates with any Mini-Fit Jr 5566 series receptacle housing — the standard mating half is a 10-position, dual-row crimp receptacle (Molex 39-01-2100 or equivalent). The square pins (0.040" typical) provide a solid solder joint and resist rotation during cable flex.
It is ROHS3 compliant.
