Product details

40-Position Mezzanine Receptacle at 0.80 mm Pitch

The Hirose FX6A-40S-0.8SV2(71) is a 40-position receptacle from the FX6 series, designed for board-to-board mezzanine stacking. Its 0.031" (0.80mm) pitch and dual-row layout pack 40 circuits into a compact footprint, with gold-plated center strip contacts for reliable signal transmission. The connector supports mated stacking heights of 7mm, 8mm, or 9mm, giving the board layout engineer flexibility in z-axis clearance between parallel PCBs.

The 0.236" (6.00mm) height above board sets the receptacle's profile on the PCB. The three supported mated stacking heights — 7mm, 8mm, and 9mm — mean the same receptacle can be paired with different plug heights to adjust the gap between boards.

The FX6A-40S-0.8SV2(71) sits at 40 positions. If the BOM calls for more I/O on the same 0.80mm pitch and 6.00mm board height, the FX6A-80S-0.8SV2(71) doubles the count to 80 positions while keeping the same footprint width and stacking height compatibility. For a 50-position need, the FX6-50S-0.8SV2(71) is the intermediate option, though it adds a board guide feature not present on this part.

What is the mating connector for FX6A-40S-0.8SV2(71)?

This receptacle mates with a Hirose FX6 series plug header of the same 0.80mm pitch and position count. The mated stacking height is set by the plug height — choose a plug that yields 7mm, 8mm, or 9mm total stack.
