What the 0.60mm pitch and 100 positions mean for your board layout
The Hirose FX8C-100S-SV(71) is a 100-position receptacle from the FunctionMax™ FX8C series, built for high-density board-to-board mezzanine stacking. The 0.024" (0.60mm) pitch on a dual-row layout packs 100 circuits into a compact footprint — the routing density forces narrower traces and tighter keep-outs than a 0.80mm or 1.00mm pitch part would allow.
Stack height flexibility — five options in one connector
This receptacle supports mated stacking heights of 5mm, 6mm, 7mm, 9mm, and 11mm when paired with the matching FX8C header. That range covers most mezzanine spacing requirements from compact handheld gear to modules that need airflow clearance between boards.
