The 0.089\" (2.26mm) height above board and supported mated stacking heights of 3mm and 4mm make it suited for compact electronics where vertical space is tight — think portable devices, telecom line cards, or embedded computing modules. ## What the 0.60mm Pitch and 140 Positions Mean for Board Layout At 0.60mm pitch, the trace routing between pads is the tightest constraint — expect 0.3mm trace/space minimum on the inner layers to escape all 140 positions. The two-row layout keeps the connector width manageable, but the 70 contacts per row demand a careful fan-out strategy, especially if you're running differential pairs. ## Stacking Height Compatibility — 3mm and 4mm Mated Options The FX8-140S-SV(22) supports mated stacking heights of 3mm and 4mm. That means you pair it with the corresponding FX8 header of the same height — the header's standoff determines the final board-to-board gap. For a 3mm stack, the total z-height from bottom PCB to top PCB is 3mm; at 4mm, you get more clearance for component keep-outs on the underside of the top board. Confirm the header part number matches your target stack height before ordering. ## Surface Mount Termination and Packaging Options This receptacle is surface mount — no through-hole tails, so it reflows on the same side as other SMD components.","metaTitle":"Hirose FX8-140S-SV(22) FunctionMax™ FX8 Receptacle, 140 Pos","metaDescription":"Hirose FX8-140S-SV(22) FunctionMax™ FX8 receptacle, 140 positions, 0.60mm pitch, SMT, gold contacts.
