Mezzanine board-stacking receptacle, 0.50mm pitch, 3mm stack height
The Hirose DF12NB(3.0)-10DS-0.5V(51) is a 10-position receptacle from the DF12 series of board-to-board mezzanine connectors. It uses a 0.020" (0.50mm) pitch in a dual-row, center strip contact arrangement, and mates to a corresponding DF12 header to achieve a 3mm mated stacking height between parallel PCBs.
This 10-position DF12NB(3.0)-10DS-0.5V(51) receptacle shares the same 0.50mm pitch, 2-row layout, 3mm stacking height, and gold contact finish with the 14-position DF12NB(3.0)-14DS-0.5V(51) and the 20-position DF12NB(3.0)-20DS-0.5V(51). All three use the same footprint pattern per row, so a layout designed for one position count can be extended to the others by adding or removing pad pairs at the same pitch.
