Active Sourcing for a 3-Pin Right-Angle SMT Header
The 5-1775444-3: This is a 3-position, single-row, shrouded-4-wall header with a 1.50mm pitch, terminated via right-angle surface-mount solder tails.
The 0.175" (4.45mm) insulation height above the board sets the clearance for the mating receptacle. Mating pin length is 0.106" (2.70mm) — ensure the mating receptacle's contact depth matches this engagement length for full wipe and retention.
Where This Header Fits in the HPI Family
Compared to the 1376366-8 (2.20mm pitch, 8-position, through-hole), the 5-1775444-3 uses a finer 1.50mm pitch for denser board layouts but carries a lower 3 A per contact vs 5 A. The 1-292164-1 (2.00mm pitch, 11-position) also uses through-hole termination and a detent lock, while this part is SMT with a latch holder. For a 3-position right-angle SMT header at 1.50mm pitch, no direct functional equivalent is listed from other series — the HPI family's 1.50mm pitch is specific to this miniaturised board-to-cable interconnect.
