The connector sits 0.106\" (2.70mm) above the board and supports mated stacking heights of 3.5mm, 4mm, and 5mm, giving the board designer flexibility in choosing the matching pin header height without changing the receptacle. ## Stack Height and Footprint Planning The 2.70mm board-mounted height combined with the 3.5mm, 4mm, or 5mm mated stack heights means the matching header must be selected to achieve the desired board-to-board gap. For a 3.5mm stack, the header height is 0.8mm; for 4mm, it is 1.3mm; for 5mm, it is 2.3mm. Compared to the DF12NB(3.0)-20DS-0.5V(51) which has a 0.087\" (2.20mm) board height, this part adds 0.5mm of clearance under the receptacle, useful when routing traces or placing components on the opposite side of the board. The 36-position variant DF12NB-36DS-0.5V(51) shares the same 2.70mm height and pitch, so the footprint pattern scales linearly with position count.","metaTitle":"Hirose DF12NB-20DS-0.5V(51) Receptacle, 20 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12NB-20DS-0.5V(51) receptacle, 20 positions, 0.50mm pitch, 2.70mm height, gold contacts.
