Mezzanine Header for Tight Board Stacks
The Hirose FX11A-80P/8-SV0.5(91) is an 80-position header from the FX11 series, designed for board-to-board mezzanine stacking.
The 3mm mated stacking height sets the board-to-board gap when this header is paired with its matching FX11 receptacle. The header itself sits 2.63mm above the board surface, so the receptacle side carries the remaining stack-up. That 0.50mm pitch keeps the footprint dense — expect tight routing between pads on inner layers, and verify the breakout via pattern fits within the keep-out zone.
