Product details

Board-to-wire header for harness termination

The 5055780571 is a 5-position, 2.00mm-pitch header from Molex's Micro-Lock PLUS 505578 series, designed to terminate a cable assembly to a PCB. It mounts surface-mount, right-angle, and mates with the matching Micro-Lock PLUS receptacle housing (sold separately). Rated -40°C to 105°C, it covers underhood and cabinet environments without derating.

The 4-wall shrouding guides the receptacle into alignment before the locking ramp engages. Termination is solder — the SMT tails are held in place during reflow by the solder retention feature on the body.

Frequently asked questions

What is the mating connector for 5055780571?

It mates with a Micro-Lock PLUS receptacle housing (e.g., 505570 series) that accepts the matching crimp terminals. The locking ramp on this header engages the receptacle latch for vibration-proof retention.
