The 3-position count means it mates with a 3-way Signal Double Lock crimp housing; the 2.50mm pitch keeps the connector compact for signal-level harnesses. ## Through-hole termination and board-mount details The 0.126\" (3.20mm) post length suits standard 1.6mm PCBs; overall contact length is 0.410\" (10.41mm). In a board-to-cable application, this height clears nearby components on the board. A board guide feature assists alignment during manual or automated placement, reducing pin damage on misaligned insertion. ## Lifecycle, compliance, and cross-reference Closest functional peer is TE 1-2232960-3, also a 3-position, 2.50mm pitch shrouded header, but rated 2 A instead of 3 A and adds glow-wire compliance. If your application can tolerate the lower current, 1-2232960-3 is a drop-in alternative.","metaTitle":"917781-1 TE Connectivity AMP Connectors 3-Position 2.50mm","metaDescription":"917781-1 TE Connectivity Signal Double Lock header, 3 circuits, 2.50mm pitch, 3A, tin-plated, shrouded, latch holder.
