Board-Stacking Fit: 0.60mm Pitch, 120 Positions, 4mm Mated Height
The mated stacking height lands at 4mm, and the header itself sits 0.152" (3.85mm) above the board — a tight z-height that suits compact enclosures where every millimeter of board spacing is allocated.
SMT Footprint and Board Guide
Surface-mount termination means the footprint is all pads — no plated through-holes eating into routing layers. The integrated board guide on the header takes the shear load during mating, protecting the fine-pitch SMT joints from peeling forces when the boards are pressed together. At 0.60mm pitch, trace escape between pads is tight; a via-in-pad or microvia strategy is worth planning for the inner rows.
Stack Height Variant vs. the 2.85mm Sibling
The FX8-120P-SV1(92) shares its 120-position count and 0.60mm pitch with the FX8-120P-SV(92), but the board height differs: 0.152" (3.85mm) here versus 0.112" (2.85mm) on the SV variant. That 1mm difference shifts the mated stack height — the SV1(92) pairs with a receptacle to give a 4mm board-to-board gap, while the SV(92) yields a lower 3mm stack. Pick the height that matches your enclosure's z-height budget and the receptacle's standoff.
