Board-to-Board Receptacle for Tight-Pitch Mezzanine Designs
The 0.024" (0.60mm) pitch packs 60 circuits into a dual-row layout, which means the footprint is dense enough that a standard soldering iron won't work — this part is designed for a reflow SMT line with a fine-pitch stencil. Gold plating on the contacts gives it the corrosion resistance and mating-cycle life expected in portable electronics and telecom line cards where the board stack may be serviced in the field. The mated stacking heights span five options — 5mm, 6mm, 7mm, 9mm, and 11mm — so the same receptacle can be paired with different-height headers to fit various enclosure z-height budgets without requalifying the board footprint.
Stack Height Selection and the 5mm Floor
Yes, the FX8C-60S-SV(71) is compatible with a 5mm mated stacking height — that's the lowest of the five supported heights. If the board-to-board gap in your enclosure is tighter than 5mm, this receptacle won't fit; the next step down would require a different connector family entirely. For a taller stack, the FX8C-60S-SV5(71) is the same 60-position, 0.60mm pitch receptacle but with a 0.352" (8.95mm) height above board, which shifts the mated stack range upward. The choice between the two comes down to the z-height budget and the mating header's height — not the footprint or the circuit count.
Sourcing and Lifecycle Position
No official second-source cross-reference exists on record; the part is sole-sourced to Hirose. If you need a different packaging format, the FX8C-60S-SV(93) is the same receptacle in Tape & Reel, Cut Tape, and Digi-Reel® packaging for automated pick-and-place lines.
