A built-in board guide aligns the connector during assembly, the ground plate provides a low-impedance return path, and the solder retention feature holds the part in place during reflow. The 5 mm mated stack height is the z-axis budget: your two boards sit exactly 5 mm apart when mated, so the mating receptacle on the opposite board must match this height. If your enclosure has a tighter or looser gap, you need a different stack height variant in the FX10 family.","metaTitle":"Hirose FX10A-120P/12-SV1(91) FunctionMax™ Header, 120 Pos","metaDescription":"Hirose FX10A-120P/12-SV1(91) FunctionMax™ FX10 SMT header, 120 positions, 0.50mm pitch, 5mm stack height, gold contacts.

The ground plate and board guide are designed to align with the matching receptacle's features. Confirm the receptacle's position count and stack height match before specifying."},{"question":"What is the replacement or equivalent for FX10A-120P/12-SV1(91)?","answer":"The FX10A-120P/12-SV1(71) is the same connector in tray packaging instead of Tape & Reel — functionally identical for the BOM line.
