The 0.50mm pitch and dual-row layout pack the 140 circuits into a compact footprint, and the 2mm mated stacking height sets the board spacing when paired with the matching FX11LA-140P-SV(22) header. ## Stacking Height and Board Spacing This receptacle sits 0.065\" (1.65mm) above the board surface. Mated with the FX11LA-140P-SV(22) header — which has a 1.90mm height above board — the total mated stack height is 2mm. That 2mm gap is the z-height budget between PCBs; the board guide features on both halves help align the stack during assembly and take shear load off the fine-pitch contacts. ## Density and Footprint Considerations At 140 positions on a 0.50mm pitch, routing the traces out of this connector demands fine-line PCB capability — the breakout channels between pads are tight. The dual-row arrangement places the contacts in two staggered rows, which helps with fan-out compared to a single-row layout at the same pitch. The 92-position FX11LA-92S-SV(21) sibling shares the same 0.50mm pitch and 1.65mm board height but reduces the circuit count for lower-density designs where the full 140 positions are not needed. ## SMT Termination and Retention","metaTitle":"Hirose FX11LA-140S-SV(22) Receptacle, 140 Pos, 0.50mm Pitch","metaDescription":"Hirose FX11LA-140S-SV(22) receptacle, 140 positions, 0.50mm pitch, 2mm stacking height.
