The Hirose FX8C-120P-SV(92) is a 120-position header from the FunctionMax™ FX8C series — a fine-pitch board-to-board interconnect built for dense parallel-stacked PCB assemblies. At 0.024" (0.60 mm) pitch, the 120 contacts in two rows pack a high signal count into a compact footprint, which means the board layout needs careful trace routing to keep escape lanes open. The outer shroud contacts and integrated board guide protect the mating interface: the guide takes the shear load during assembly so the fine-pitch beams don't stub on the receptacle. Gold contact finish on both mating surfaces supports repeated mating cycles without oxidation creep, matching the typical reconnect duty in modular mezzanine or mid-plane designs.
No last-time-buy or phase-out notice is on record. The base product number FX8 covers the full FunctionMax family; the suffix (92) denotes the Tape & Reel packaging variant, while the (91) suffix ships in Tube.
