100-Position Board-to-Board Plug for Dense Parallel Stacks
The Hirose FX2C-100P-1.27DSA(71) is a 100-position board-to-board plug from the FX2 series, designed for high-density parallel board stacking. The connector uses center strip contacts, giving each signal path a consistent impedance environment through the mated pair. The through-hole solder termination anchors the plug to the board with mechanical strength the SMT-only alternatives lack, especially on a 100-position part where the combined insertion force of the contacts can stress a surface-mount joint.
Mating and Board Stack Height
The 1.27 mm pitch and two-row layout mean the footprint on each board is identical, simplifying the PCB layout for the parallel stack.
