Board-to-Board Plug for Parallel PCB Stacking
The Hirose FX2CA-32P-1.27DSA(71) is a 32-position plug from the FX2 series of board-to-board connectors. The gold-plated contacts, at 7.87 µ" (0.200 µm) thickness, suit moderate-cycle-count applications where signal integrity over repeated mates matters — typical for mezzanine or parallel-stacked board interconnects in industrial controllers, test equipment, and telecom line cards. The through-hole mounting gives the plug the mechanical anchor needed to withstand the insertion force of its mating receptacle.
Position Count and Pitch — Matching the BOM Line
At 32 positions on a 1.27 mm pitch, this plug matches the circuit count of a 32-conductor board-to-board link. The 1.27 mm pitch is a standard for moderate-density stacking — it leaves enough routing channel per signal layer without forcing fine-line board fabrication. The two-row layout keeps the connector width manageable for a 32-position count.
The closest functional peer is the FX2C1-32P-1.27DSA(71), which shares the same 32 positions, 1.27 mm pitch, gold plating, and through-hole termination — a direct parametric match for a second-source BOM line.
