Board Layout Fit for a 0.40 mm Pitch Mezzanine Receptacle
The Hirose DF37NB-34DS-0.4V(51) is a 34-position receptacle from the DF37 series, designed for parallel board stacking. It uses a 0.016" (0.40mm) pitch across two rows of center strip contacts, with gold plating at 2.00µin (0.051µm) on the mating surface. The connector sits 0.038" (0.97mm) above the board and mates to a stack height of 0.98mm — a tight z-budget that suits compact handheld or portable electronics where board-to-board spacing is at a premium.
It is RoHS compliant.
