The 2074781005: This is a Molex L1NK 396 207478 series header, 5 circuits in a single row, pitched at 0.156" (3.96mm). It's a board-to-cable/wire interconnect: the male pins mate with a crimp-terminal receptacle housing, not another board-mounted connector. The through-hole mounting and tin-plated contacts (both mating and post) suit moderate-duty signal and power connections in automotive, industrial, medical, and telecom equipment.
The 3.96mm pitch is deliberate: it's wide enough to carry a few amps per contact without significant temperature rise, yet tight enough to keep a 5-position connector compact on the board. The 0.476" (12.10mm) insulation height means the shroud stands tall enough to accommodate a latch on the mating half. The 0.138" (3.50mm) post length is standard for 1.6mm PCBs; if your board is thicker, confirm the solder joint will fill through the hole.
Glow Wire Compliant and Latch Holder — Safety and Retention
Glow wire compliance (likely per IEC 60335-1) means this header can be used in appliances where a glowing element must not ignite the housing. Combined with the UL94 V-0 LCP housing, this is a robust part for environments where both thermal and mechanical reliability matter.
