Board-stacking receptacle for tight z-axis budgets
The Hirose DF37NC-60DS-0.4V(51) is a 60-position, 0.40mm pitch receptacle with center strip contacts, designed for surface-mount board-to-board stacking. This is the highest position-count member in the DF37 series, giving you 60 circuits in a dual-row layout. The mated stacking height is 0.98mm — that is the full z-height from the top of the bottom board to the bottom of the top board, so it fits into the thinnest mezzanine gaps in handheld or portable equipment. Gold contact finish with 2.00µin thickness handles the mating cycles typical of internal board stacks in consumer electronics, wearables, and compact modules.
60 positions vs the 50-position sibling — same footprint, more I/O
The DF37NC-60DS-0.4V(51) shares the same 0.40mm pitch, 0.97mm height above board, and gold contact finish as the DF37NC-50DS-0.4V(51). Both are dual-row receptacles in the same DF37 series, so the PCB footprint pitch and row spacing are identical. The 60-position version gives you 10 extra signal lines in the same board area — useful when you need to route more data or power lines through the same stack height budget.
Active production — no last-time-buy risk
RoHS compliant per the listing. No official cross-reference or second-source exists — the DF37 series is Hirose-specific.
