80-Position Mezzanine Header, 0.60mm Pitch
With a 0.024" (0.60mm) pitch and two rows, it packs high signal density into a small footprint — typical for parallel data buses or dense I/O arrays in portable equipment, telecom line cards, and industrial controllers.
The 0.152" (3.85mm) height above board sets the mated stack height at 4mm when paired with the matching FX8 receptacle. This is a fixed-height mezzanine connection — the z-height budget is locked once you pick the header and receptacle pair. If you need a different board gap, the FX8 series offers a 2.85mm-height variant (FX8-80P-SV(92)) that mates to a shorter stack. For this 3.85mm header, the 4mm stack suits applications where the mezzanine board sits just above the main PCB, leaving clearance for low-profile components underneath.
Mounting and Assembly
Surface-mount termination with gold-plated contacts. The board guide is a practical feature — it steers the receptacle into alignment during mating, which matters when you're stacking boards in a chassis where you can't see the pins. No press-fit or through-hole solder; it's a reflow-only part, so plan for a standard SMT line. Packaged in trays, not tape-and-reel, which is typical for larger mezzanine headers.
Mates with the matching FunctionMax™ FX8 receptacle (the FX8 series receptacle with the same 0.60mm pitch and 80 positions). The 4mm mated stack height is the result of pairing this 3.85mm header with the standard receptacle — confirm the receptacle's height spec if you need a different board gap.
