Hirose DF9-31S-1V(69) — 31-Position, 1.00 mm Pitch SMT Receptacle
The Hirose DF9-31S-1V(69) is a 31-position receptacle with outer shroud contacts, part of the DF9 series of board-to-board connectors.
Mated Stacking Height and Board Fit
For applications requiring frequent field reconnections or exposure to corrosive atmospheres, a heavier gold plating (8.00µin or more) on the matching header provides additional margin. The DF9-31P-1V(69) header carries 8.00µin (0.203µm) gold, giving the pair a combined plating thickness that extends cycle life.
Position Count and Series Siblings
At 31 positions, this receptacle matches a 31-circuit BOM line. The same-footprint sibling DF9-41S-1V(69) carries 41 positions at the same 0.039" (1.00mm) pitch and 0.130" (3.30mm) height above board — the extra 10 circuits extend the connector body length proportionally, so the board layout must accommodate the longer footprint. No other position count shares the exact same mechanical outline.
