Active production — 2-position Signal Double Lock header
The 917780-1 is an active-production TE Connectivity AMP Connectors Signal Double Lock header — no end-of-life risk for new builds or replenishment. Rated 3A per contact at 50V, with tin-plated mating surfaces — suitable for general-purpose signal and low-power interconnect inside equipment enclosures.
Board fit and footprint check
The 2.50mm pitch and through-hole termination with kinked pins set the PCB footprint — confirm the 0.126" (3.20mm) post length clears the board thickness and the 0.410" (10.41mm) overall contact length fits the z-height budget.
Peer cross-reference — 1-2232960-3 for 3-position need
The closest functional sibling is 1-2232960-3: same 2.50mm pitch, single-row, shrouded 4-wall, through-hole, tin-plated contacts, but with 3 positions and a locking ramp instead of a latch holder. If the BOM requires 3 circuits, 1-2232960-3 is a direct drop-in for the same footprint — only the position count and fastening style differ.
