Board-to-Board Mezzanine Fit: 2mm Stack Height at 0.40mm Pitch
The Hirose DF40B(2.0)-12DS-0.4V(58) is a 12-position receptacle from the DF40 series, designed for parallel board stacking at a fixed 2mm mated height. The 0.016" (0.40mm) pitch and dual-row layout pack 12 circuits into a compact footprint — the tight pitch demands careful trace routing on the board, but the 2mm stack height gives enough clearance for mid-board components on the underside of the top PCB.
ROHS3 compliant.
