80-Position Mezzanine Header at 0.60 mm Pitch
Typical applications include internal board stacking in portable electronics, telecom line cards, and industrial control modules where the PCB real estate is the constraint, not the current per line.
Stack Height Selection: 7 mm or 12 mm
This header supports two mated stacking heights: 7 mm and 12 mm. For a 7 mm stack, pair it with the corresponding FX8C receptacle that adds roughly 0.55 mm above its own board; for 12 mm, use the taller receptacle variant.
Stack Height Delta vs. FX8C-80P-SV1(92)
The closest functional sibling is the FX8C-80P-SV1(92), which shares the same 80-position count, 0.60 mm pitch, gold plating, and SMT mounting. The sole selection-relevant difference is the height above board: 0.254" (6.45mm) for the SV2 versus 0.214" (5.45mm) for the SV1. That 1.00 mm height delta shifts the mated stack range — the SV1 supports a 6 mm stack height, while the SV2 supports 7 mm and 12 mm. Choose the SV2 when the board-to-board gap requires the taller 7 mm or 12 mm envelope; the SV1 fits tighter 6 mm stacks.
