1.25 mm pitch, 4 circuits — the footprint check
The 5055680431: This is a 4-position, single-row header on a 1.25 mm pitch. That pitch sets the board footprint and the mating interface — it mates with Micro-Lock PLUS receptacle housings from the same 505568 series. The 4-wall shroud protects the pins during blind mating and guides the receptacle into alignment.
Current rating depends on your wire — not a fixed number
The current rating is listed as varying by wire gauge. For a given application, the current capacity is set by the wire size chosen for the mating terminal — the header itself does not impose a single ceiling. That covers automotive underhood and industrial cabinet environments where the connector sees both cold start and sustained heat.
SMT termination with pick-and-place and solder retention
This header is surface-mount, supplied in tape and reel for automated assembly. The mated stacking height is 7.4 mm. That is the z-height from the PCB surface to the top of the mated receptacle — important when routing the board inside a tight enclosure.
