Board-stacking selection: 0.50 mm pitch, 50 positions, three z-height options
The DF12NB-50DS-0.5V(51): The 2-row layout with center strip contacts keeps the footprint compact — the 0.50 mm pitch means the board traces need careful routing, especially on inner layers where via clearance is tight. The mated stacking heights are 3.5 mm, 4 mm, and 5 mm, which cover the most common mezzanine gaps for portable electronics, handheld devices, and compact modules. The 2.70 mm height above board gives the receptacle a low profile on the PCB.
