Board spacing and footprint fit
The DF12B(3.0)-60DP-0.5V(86): This is a 0.50 mm pitch, 60-position header from the Hirose DF12 series, designed for parallel board stacking at a fixed 3 mm mated height. The 3 mm stack height sets the clearance between boards, so verify component heights on both sides before committing the layout.
Mates with the DF12 series receptacle (same pitch and position count).
