Product details

Mezzanine Header for Dense Board Stacks

The Hirose FX10A-100P/10-SV(91) is a 100-position, dual-row header from the FunctionMax™ FX10 series, designed for board-to-board mezzanine stacking. It carries a 0.020" (0.50mm) pitch and a mated stacking height of 4mm, placing it in the lower-profile range of the FX10 family.

At 4mm mated stack height, this header pairs with the matching FX10 receptacle to set the gap between parallel PCBs. For a taller stack, the sibling FX10A-100P/10-SV1(91) uses a 0.177" (4.50mm) height above board, yielding a 4.50mm mated stack — a 0.50mm increase that can accommodate thicker components on the underside of the top board.

SMT Termination and Board Retention

Surface-mount termination suits automated pick-and-place assembly. The header includes a solder retention feature and a board guide — the guide eases alignment during blind-mate assembly, and the ground plate provides a low-inductance return path that also helps with EMI containment.
