It uses a 0.039\" (1.00mm) pitch and surface-mount termination, with gold-plated contacts at 8.00µin thickness. The mating receptacle must match this pitch exactly — the DF9B-31S-1V(69) is the correct partner. The 4.3mm mated stack height is a fixed value, not adjustable; the designer must verify that the enclosure gap and the opposing board's component height clear this dimension. The dual-row layout gives 31 positions in a compact footprint, but the narrow pitch means the board layout engineer should check for adequate clearance between adjacent traces, especially if routing between the pads. ## Gold vs Tin — Which Plating for Your Duty For builds that require field-service reconnection or higher reliability over time, the gold-plated (69) version is the right call. The DF9-31P-1V(69) adds a board guide feature for alignment during assembly, while the DF9B version relies on solder retention alone — a difference in how the part self-aligns on the board before reflow.","metaTitle":"Hirose DF9B-31P-1V(69) Header, 31 Pos, 1mm Pitch, SMT","metaDescription":"Hirose DF9B-31P-1V(69) header, 31 positions, 0.039\" (1.00mm) pitch, SMT, gold contacts.
