Board-Stacking Fit for a 60-Position Mezzanine
The Hirose DF12NC(3.0)-60DS-0.5V(51) is a 60-position receptacle from the DF12 series, designed for board-to-board mezzanine stacking at a fixed 3mm mated height. The 0.50mm pitch and 2-row layout pack 60 circuits into a compact footprint — the position count is the highest available at this stacking height in the DF12NC(3.0) sub-series. Gold-plated center strip contacts (8.00µin) handle signal-level duty with enough corrosion resistance for controlled indoor environments. Surface-mount termination keeps the assembly reflow-compatible.
What the 3mm Stacking Height Means for the Build
The 3mm mated stacking height sets the board-to-board spacing — every other dimension in the enclosure (component clearance, standoff height, opposite-side keep-outs) must respect that z-height budget. The 0.50mm pitch forces tight trace routing between pads; a 2-layer board with 0.5mm pitch fanout typically needs at least a via-in-pad or microvia strategy to escape the inner rows.
Mating Half and Orientation
This receptacle mates with the DF12NC(3.0)-60DP-0.5V(51) header, which uses outer shroud contacts and the same 0.50mm pitch and 60 positions. The header has a 2.30mm height above board, giving the pair a 3mm mated stack. Both parts are surface-mount, so the board-to-board alignment relies on the solder pads and the connector body's own registration — no separate alignment pins on this variant.
