It uses a 0.020\" (0.50mm) pitch in a 2-row, center strip contact layout, with gold-plated contacts (4.00µin thickness) for reliable signal integrity across repeated mating cycles. The connector stands 0.126\" (3.20mm) above the board and supports mated stack heights of 4mm and 5mm, giving the board layout engineer two spacing options for parallel PCB stacking. ## Stack Height and Board Spacing Options The FX10A-140S/14-SV(71) is rated for mated stack heights of 4mm and 5mm. ## Board Guide, Ground Plate, and Solder Retention Three built-in features address the main failure modes of a fine-pitch mezzanine connector. The board guide aligns the receptacle during blind-mate assembly, preventing bent contacts when the boards are stacked. The ground plate provides a low-inductance return path — critical for high-speed signals where a missing reference plane causes impedance discontinuities. The FX10 series offers several position counts at the same 0.50 mm pitch and 3.20 mm board height. The 140-position FX10A-140S/14-SV(71) sits between the 120-position FX10A-120S/12-SV(71) and the 144-position FX10A-144S-SV. The 168-position FX10A-168S-SV is the densest option in the same row count, but it requires a longer board footprint. No second-source or cross-reference from another manufacturer is on record.","metaTitle":"Hirose FX10A-140S/14-SV(71) FunctionMax™ Receptacle","metaDescription":"Hirose FX10A-140S/14-SV(71) FunctionMax™ FX10 receptacle, 140 positions, 0.50mm pitch, 2 rows, SMT, gold plating, 4mm/5mm stack heights.
