Its 1.25mm pitch and 7.4mm mated stack height suit it for low-profile, space-constrained harnesses in automotive, industrial, and general-purpose equipment.
The 1.25mm pitch and single-row layout define the PCB footprint: three through-hole or SMT pads on a 1.25mm grid. The header mates with Micro-Lock PLUS receptacle housings (e.g., 505567 series) using the push-pull fastening system.
It mates with a Micro-Lock PLUS receptacle housing from the 505567 series, using the push-pull locking system. The mating receptacle accepts the same 1.25mm pitch crimp terminals.
No. The 5055680381 is a 3-position header; the 5055680481 is a 4-position header. They share the same series and pitch but differ in circuit count, so they are not direct replacements.
The current rating varies by wire gauge used in the mating receptacle. The header itself does not carry a fixed ampacity; it depends on the terminal and wire size selected for the harness.
