Hirose FX8C-140S-SV5(92) — 140-Position, 0.60 mm Pitch Mezzanine Receptacle
It uses a 0.60 mm pitch and a dual-row center strip contact layout, with surface-mount termination. The mated stacking height range — 10 mm, 11 mm, 12 mm, 14 mm, and 16 mm — is set by the mating header (not included). This receptacle alone does not determine the stack height; pair it with the corresponding FX8C header of the same position count and the desired height code. The 0.60 mm pitch and 140 positions make this a high-density interconnect for parallel board assemblies where signal routing density and a low profile matter.
Mated Stacking Heights and Board Spacing
This receptacle supports mated stacking heights of 10 mm, 11 mm, 12 mm, 14 mm, and 16 mm when mated with the correct FX8C header. The stack height is determined by the header's height above board — the receptacle height above board is fixed at 8.95 mm. For a 10 mm stack, the header's mating face sits 1.05 mm above the board; for 16 mm, the header stands 7.05 mm above the board. Verify the header's height code (e.g., -SV5 for 8.95 mm receptacle height) matches the target board spacing.
Comparison with FX8C-140S-SV5(91) and FX8C-100S-SV5(92)
The FX8C-140S-SV5(91) is electrically and mechanically identical — same 140 positions, same 0.60 mm pitch, same 8.95 mm height — but ships in a Tube, not Tape & Reel. If your pick-and-place line requires Tape & Reel, the (92) suffix is the correct order code. The FX8C-100S-SV5(92) drops to 100 positions at the same pitch and height, for applications that need fewer signal lines but the same board spacing and footprint class.
It is a current-production part with no announced end-of-life. No official second-source or cross-reference on record; the FX8C series is Hirose-proprietary in footprint and mating interface.
