0.50mm Pitch Mezzanine Header, 96 Positions, 5mm Stack Height
The mated stack height is fixed at 5mm, set by the header height of 0.177" (4.50mm) above the board plus the matching receptacle's height.
Position and Stack Height Options in the FX10 Series
The FX10A-96P-SV1(71) shares the same 0.50mm pitch, dual-row layout, and gold plating as the FX10A-144P-SV1(71), but the 96-position count is the key difference — 96 circuits vs 144 circuits, which changes the board footprint width and the routing density required. The stack height also varies: this part mates at 5mm, while the FX10A-96P-SV(71) (without the "1" suffix) mates at 3.50mm. The 5mm stack gives more room for mid-board components under the mezzanine, but the 3.50mm version is a tighter fit for low-profile enclosures. Both are active and use the same receptacle family, so the choice comes down to the z-height budget and the number of signals.
