Mates with any Mini-Fit Jr 5556 or 5557 receptacle housing that carries 8 circuits and accepts the 4.20mm pitch.
In a panel that gets cycled quarterly, that gold thickness supports well over a decade of service before the contact interface wears through to the base metal. Tin on the solder tails keeps the cost down where the connection is made once.
Any Mini-Fit Jr 5556 or 5557 series receptacle housing with 8 circuits and 4.20mm pitch will mate with this header.
The mating pitch is 0.165" (4.20mm), and the row spacing is the same 0.165" (4.20mm).
