The Hirose FX8C-120P-SV6(92) is a 120-position header from the FunctionMax™ FX8C series, using a 0.024" (0.60 mm) pitch in a dual-row arrangement. With a board height of 0.427" (10.85 mm), it supports mated stack heights of 11 mm and 16 mm, giving the layout engineer two z-axis options from the same footprint. Typical applications include high-density signal interconnects in telecom, networking, and server equipment where routing density and a low-profile board gap are critical.
Stack Height and Footprint Flexibility
The 10.85 mm board height is the tallest in the FX8C 120-position family, and the connector is rated for two mated stack heights (11 mm and 16 mm) depending on the mating receptacle chosen. That means the same PCB footprint can serve two different mezzanine gaps without a layout change, which simplifies inventory if the build runs multiple board spacings.
