80-Position, 0.60 mm Pitch Mezzanine Header for Tight Board Stacking
The Hirose FX8-80P-SV(92) is an 80-position header from the FunctionMax™ FX8 series, designed for board-to-board mezzanine interconnects where board real estate is at a premium. The 0.60 mm pitch and 2.85 mm mated stack height suit applications like compact handheld devices, portable instrumentation, and dense server blades where the z-height budget is tight. The outer shroud contacts provide mechanical protection during mating and help guide the receptacle into alignment.
0.60 mm Pitch and 2.85 mm Stack Height Define the Footprint
The 0.60 mm pitch is the tightest in the FX8 series, which means the board-level routing must accommodate fine-pitch traces between pads — typically a 4-layer or higher PCB stack-up with controlled impedance if the signal edges are fast.
