Board-to-Board Stacking Header for Mezzanine Designs
The Hirose FX6-20P-0.8SV(93) is a 20-position, dual-row header from the FX6 series, designed for parallel board-to-board stacking in mezzanine configurations. At a 0.031" (0.80mm) pitch, it packs 20 gold-plated contacts into a compact footprint, with a fixed height above board of 0.197" (5.00mm). The connector supports two mated stacking heights — 5mm and 7mm — giving the board designer flexibility in z-axis spacing between the two PCBs. Gold finish on all contacts suits it for signal-level interconnects where repeated mating cycles or long-term reliability matter.
Stack Height and Mating Options
The Tape & Reel packaging is intended for automated pick-and-place assembly. The mating receptacle determines the final stack height: a 5mm mated height uses a standard FX6 receptacle, while a 7mm stack uses a taller version.
Comparing the FX6-20P-0.8SV(93) with Its Siblings
The closest functional sibling is the FX6-20P-0.8SV(71), which shares the same 20-position count, 0.80mm pitch, 5mm height, and gold contacts, but ships in a Tube rather than Tape & Reel. For 40 signals, the FX6-40P-0.8SV(71) doubles the position count at the same pitch and height. If the board stack needs 6mm clearance, the FX6-20P-0.8SV1(71) offers a 0.236" (6.00mm) height. The (93) variant's Tape & Reel packaging is the practical difference for volume SMT lines.
