It uses a 0.020\" (0.50mm) pitch dual-row layout with outer shroud contacts, surface-mount termination, and a mated stacking height of 5mm. Typical applications are high-density internal interconnects in networking gear, servers, and portable electronics where signal count is high and z-height is tight. ## 5mm Stack — One Height, One Decision The 5mm mated stacking height is the defining mechanical spec here. The sibling FX10A-144P-SV(71) shares the same 144 positions and 0.50mm pitch but stacks at 3.50mm, so swapping between them changes the board-to-board gap by 1.5mm. If your enclosure and connector keep-out zone are locked to 5mm, this is the one. The 168-position FX10A-168P-SV1(71) keeps the same 5mm stack and 0.50mm pitch but adds 24 more signal paths — a direct swap if your layout has the extra routing channels. No official cross-reference or second-source exists; the mating receptacle is the FX10 series socket half. ## Gold Flash — Signal Duty, Not High-Cycle","metaTitle":"Hirose FX10A-144P-SV1(71) Header, 144 Pos, 0.50mm Pitch","metaDescription":"Hirose FunctionMax FX10A-144P-SV1(71) header, 144 positions, 0.50mm pitch, 5mm stacking height, SMT, gold contacts.
