30-position, 0.50mm pitch header for 5mm board stacking
The DF12D(5.0)-30DP-0.5V(81): This is a 30-position, dual-row header from the Hirose DF12 series, pitched at 0.020" (0.50mm) and designed for a 5mm mated stacking height between boards. The connector type is a Header, Outer Shroud Contacts — the outer shroud provides mechanical alignment and protects the signal pins during mating, which matters when you're stacking boards blind in a tight enclosure.
Obsolete — plan your BOM transition
For a BOM already using this order code, the immediate step is to source remaining inventory or identify a pin-compatible replacement within the DF12 series that matches the 0.50mm pitch and 5mm stack height.
