This housing is the receptacle half of a Mini-Fit Jr power interconnect. It mates with the corresponding Mini-Fit Jr 5559 header (through-hole or vertical mount) to carry DC power from a board to a wire harness. The latch lock keeps the pair mated in applications with moderate vibration — think power supplies, industrial controls, automotive interior modules, and appliance PCB-to-harness connections.","metaTitle":"Molex Mini-Fit Jr 5557 0039012080 Receptacle, 8-Circuit","metaDescription":"Molex 0039012080 Mini-Fit Jr receptacle housing, 8 circuits, 4.20mm pitch, natural PA66, latch lock.
