80 positions at 0.50mm pitch — board layout fit
The DF12B(3.0)-80DP-0.5V(86): This is an 80-position, 0.50mm pitch, 2-row header from the Hirose DF12 series. The 0.50mm pitch and 80 positions demand a multi-layer PCB for fan-out — two-layer boards will struggle to route all signals without vias. Mated stacking height is fixed at 3mm — the (3.0) in the order code. That is the only stack height this variant supports; the board spacing is non-negotiable.
