0.60mm Pitch, 120-Position Mezzanine Header for Tight Board Spacing
With a 0.024" (0.60mm) pitch and dual rows, it packs 120 circuits into a compact footprint — the pitch drives the PCB routing density and the footprint land pattern. The header uses outer shroud contacts and surface-mount termination, with gold contact finish for reliable signal integrity across repeated mating cycles. It sits 0.254" (6.45mm) above the board and supports mated stacking heights of 7mm and 12mm, giving the board layout engineer two board-spacing options with the same header.
Stack Height Options: 7mm or 12mm from One Header
The FX8C-120P-SV2(91) is specced for mated stacking heights of 7mm and 12mm — the header height above board is fixed at 0.254" (6.45mm), and the mating receptacle's height determines the final stack. Compare this to the FX8C-120P-SV(91), an otherwise identical 120-position header with the same 0.60mm pitch and gold contacts, but a lower 0.175" (4.45mm) height above board. The FX8C-120P-SV(91) targets tighter z-axis budgets where 4.45mm is the limit. For the same circuit count and footprint, the choice between the two comes down to the board spacing your enclosure allows. The FX8C-120P-SV2(92) is the same header as this one, same 6.45mm height, but packaged in Tape & Reel — a sourcing fork for volume pick-and-place lines that prefer reel feed over tube.
No obsolescence notice or last-time-buy window is on record. For compliance and quality checks, the ROHS3 rating covers the full directive scope, and the gold contact finish meets typical industrial reliability requirements for high-cycle applications.
This is the header (plug) side of the FunctionMax™ FX8C board-to-board interconnect. It mates with the corresponding FX8C receptacle series — the FX8C-120S-SV2 is the direct mating half for this 120-position, 0.60mm pitch stack. Termination is surface mount, with the board guide feature aiding alignment during reflow assembly.
