Product details

2-position, 2mm-pitch header for wire-to-board locking

Pitch, positions, and footprint fit

At 2.00mm pitch and 2 positions, this header is the smallest circuit count in the Micro-Lock PLUS 505575 series — compare with the 4-position 5055750471 or 5-position 5055750571 for higher-density needs. The mated stacking height is 11.1mm, and the insulation height is 0.339" (8.61mm), which sets the z-height budget for the mated assembly.

Frequently asked questions

What is the mating connector for Molex 5055750271?

This is a board-to-cable/wire header; it mates with a Micro-Lock PLUS receptacle housing and crimp terminals (sold separately). The locking ramp on the header engages with the receptacle latch for vibration-proof retention.

Is 5055750271 RoHS compliant?

Yes, the 5055750271 is ROHS3 compliant.

What is the current rating of Molex 5055750271?

The current rating varies by wire gauge used in the mating terminal — it is not a fixed value for the header alone. Refer to the Micro-Lock PLUS terminal datasheet for derated current per wire size.

What is the pitch of 5055750271?

The pitch is 0.079" (2.00mm).
