The 2.26mm height above board sets the clearance under the component side, and the mated stacking height works with the matching FX8 plug header to give a 3mm or 4mm board-to-board gap — two common mezzanine spacings for stacking processor boards, memory modules, or FPGA carrier cards. The 0.60mm pitch is the critical dimension for the PCB footprint — it dictates trace escape routing between the pads and forces either micro-vias or tight neck-downs on inner layers. With 140 positions across two rows, the connector body spans roughly 42mm along the board edge. The board guide built into the housing helps align the receptacle to the mating plug during assembly, which matters when you're blind-mating a 140-circuit connector in a production line. The two supported mated stacking heights — 3mm and 4mm — come from the plug header height selection, not from this receptacle itself; the FX8-140S-SV stays at a fixed 2.26mm above the board, and the plug's height determines the final gap. Pick the plug that gives the clearance your tallest component under the mezzanine board needs.","metaTitle":"FX8-140S-SV FunctionMax™ FX8 Receptacle, 140 Pos","metaDescription":"FX8-140S-SV FunctionMax™ FX8 receptacle, 140 positions, 0.60mm pitch, dual-row SMT.
