Mezzanine Header for Tight Board Spacing
The Hirose DF12NB(5.0)-50DP-0.5V(51) is a 50-position header from the DF12 series, designed for board-to-board mezzanine stacking.
Pitch and Stack Height Drive the Footprint
At this pitch, a 2-row, 50-position layout needs careful routing to avoid neck-downs.
Position Counts Across the DF12 Series
The DF12NB(5.0)-50DP-0.5V(51) is one position option in a family that includes 30-, 36-, and 60-position variants — all sharing the same 0.50 mm pitch, 5 mm stack height, and gold plating. The 50-position count is a middle-density choice; the 60-position version (DF12NB(5.0)-60DP-0.5V(51)) adds 10 more circuits at the same pitch, which widens the footprint by about 5 mm along the connector length.
