0.40mm-Pitch Board-to-Board Header for Tight Stacking
The Hirose DF37B-16DP-0.4V(53) is a 16-position header in the DF37 series, using a 0.016" (0.40mm) pitch dual-row layout with outer shroud contacts. It sits 0.030" (0.75mm) above the board and mates to a stacking height of 0.98mm — about the thickness of two stacked PCBs. Surface-mount termination and a Tape & Reel package feed into a pick-and-place line. The base product number is DF37B.
Position Count Options at the Same Footprint
The DF37B series offers 10, 16, 20, and 24 positions at the same 0.40mm pitch and 0.75mm board height. The 16-position DF37B-16DP-0.4V(53) sits in the middle of that range. If the BOM calls for 10 circuits, the DF37B-10DP-0.4V(53) shares the same footprint class and stack height; for 20 or 24 circuits, the DF37B-20DP-0.4V(53) or DF37B-24DP-0.4V(53) are the direct step-ups. All use gold contacts with 2.00µin plating and solder retention. The choice is purely circuit count — no change in board keep-out or mating receptacle family.
