1.00 mm Pitch, 31-Position SMT Header for Tight Board Spacing
The Hirose DF9-31P-1V(32) is a 31-position, 2-row header from the DF9 series, designed for parallel board-to-board stacking at a fixed 4.3 mm mated height. The 0.039" (1.00mm) pitch packs 31 circuits into a compact footprint — the odd count means every position on the BOM is accounted for, with no unused pins.
Tin Contacts — 39.4 µin for a Few Mating Cycles
For repeated disconnect-reconnect cycles, the gold-plated DF9-31P-1V(69) is the same header with 8.00µin gold, which resists fretting corrosion better.
Mates with the DF9-31S-1V(32) Receptacle
This header mates directly with the DF9-31S-1V(32) receptacle, also a 31-position, 2-row, 1.00mm pitch SMT part with tin contacts. The 4.3 mm stack height is fixed — no shims or spacers needed.
