Board-fit and routing at 1.25 mm pitch
The 5055680871: This is an 8-position, single-row header from the Micro-Lock PLUS 505568 series, pitched at 1.25 mm (0.049 in) — tight enough to save board space but wide enough for manual routing between pads.
Tin is a workhorse finish for moderate-cycle applications — it's cost-effective and mates well with tin-plated receptacle contacts. The current rating depends on wire gauge, so the limiting factor is the crimp terminal and wire size, not the header contact itself.
