It uses a 0.020\" (0.50mm) pitch across 2 rows, which keeps the board footprint compact while delivering 80 signal or power circuits. The mated stacking height is 5mm — that's the dimension that decides whether this connector fits the z-height budget between your PCBs. ## Pitch and footprint — what the 0.50mm means for layout The 80 positions on 2 rows give 40 contacts per row, so the footprint length across the board is about 20mm (40 × 0.50mm). The ground plate in the centre of the connector provides a low-inductance return path — useful if you're running high-speed signals through a mezzanine link. The solder retention tabs anchor the header during reflow and add shear strength against the cable or board strain that comes from the mating side. ## Mated stack height — the z-height decision The 5mm mated stacking height is the single most important dimension for a mezzanine application. It sets the gap between the two parallel PCBs. The height above board on this header is 0.177\" (4.50mm), so the mating receptacle (sold separately) contributes the remaining 0.50mm to reach the full 5mm stack. If your enclosure has a fixed board-to-board spacing, verify that the total stack — this header plus its mating half — lands at exactly 5mm. The board guide features help align the two halves during assembly, which is critical at this pitch where a slight angular misalignment can bend contacts.","metaTitle":"FX10A-80P/8-SV1(71) FunctionMax™ FX10 Header, 80 Pos, 0.50mm","metaDescription":"Hirose FunctionMax™ FX10A-80P/8-SV1(71) — 80-position, 0.50mm pitch SMT header, 5mm mated stack height, gold contacts.
