High-Density Mezzanine Header for Tight Stack-Up Budgets
The Hirose FX8C-140P-SV1(91) is a 140-position, 2-row header from the FunctionMax™ FX8C series, designed for board-to-board mezzanine stacking. At a 0.024" (0.60mm) pitch, it packs 70 contacts per row into a compact footprint — the kind of density you need when routing a large number of differential pairs or single-ended signals through a midplane. The header stands 0.214" (5.45mm) above the board and supports mated stack heights of 6mm or 11mm, giving the layout engineer two z-height options from the same PCB footprint.
No end-of-life notice has been issued, so it can be specified into new designs without an LTB watch.
