Tin-to-tin contacts are rated for fewer mating cycles than gold — typically 25-50 cycles before fretting corrosion raises resistance. ## 12 vs 13 Positions — Peer Cross-Shop The 13-position sibling 917791-1 shares the same 2.50 mm pitch, 3 A current, tin contacts, latch holder, and UL94 V-0 housing. The only difference is one additional circuit — same board footprint width, same mating receptacle series. ## Board Guide and Shrouded Walls — Alignment and Protection The header includes a board guide to align the connector during mating, reducing pin damage from off-angle insertion. Kinked pin solder tails provide through-hole retention during wave soldering, holding the header square to the board before the solder joint sets.","metaTitle":"917790-1 TE Connectivity AMP Connectors Header 12POS 2.5mm","metaDescription":"917790-1 Signal Double Lock header, 12 positions, 2.50mm pitch, 3A, 50V, tin contacts, latch holder, UL94 V-0.
