It uses a 0.50mm pitch and a 2-row layout, with center strip contacts that mate to the corresponding DF12 header. The connector is surface-mount, sitting 2.70mm above the board, and supports mated stacking heights of 3.5mm, 4mm, and 5mm depending on the header height chosen. ## Stack Height Flexibility for Board Spacing This receptacle is designed to work with DF12 series headers at three mated stacking heights — 3.5mm, 4mm, and 5mm — giving the board layout engineer options for z-axis clearance between parallel PCBs. The 0.50mm pitch keeps the footprint tight, but the 2-row arrangement at 20 positions means the board escape routing needs care: you're fitting 10 contacts per row into a narrow keep-out zone, so a via-in-pad or fine-trace strategy is typical for the inner rows. ## Comparing the 2.70mm and 2.20mm Height Variants The DF12NC-20DS-0.5V(51) sits 2.70mm above the board. A sibling variant, DF12NC(3.0)-20DS-0.5V(51), shares the same 0.50mm pitch, 20 positions, and gold plating but has a lower 2.20mm board height. The choice between them is driven by the required mated stack height: the 2.70mm receptacle pairs with taller headers for the 3.5mm to 5mm stack range, while the 2.20mm version targets tighter z-axis budgets. Both are active and RoHS-compliant, so the decision is purely mechanical — match the board-to-board gap in your enclosure.","metaTitle":"Hirose DF12NC-20DS-0.5V(51) Receptacle, 20 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12NC-20DS-0.5V(51) receptacle, 20 positions, 0.50mm pitch, 2 rows, SMT, gold contacts.
