The Hirose DF12D(3.0)32DP0.5V80 is a 32-position header from the DF12 series, designed for board-to-board mezzanine stacking. It uses outer shroud contacts on a 0.50mm pitch in two rows, with a mated stacking height of 3mm and a height above board of 2.30mm. The gold-plated contacts and surface-mount termination suit it for dense, low-profile interconnects inside portable electronics, telecom modules, and industrial control boards where the board stack height budget is tight.
At 0.50mm pitch, the routing density is high — trace-and-space below 0.25mm is typical, and the board house needs to support fine-pitch escape routing from the SMT pads. The 32 positions in two rows give 16 contacts per row, which keeps the connector body compact but demands a precise footprint alignment.
The 2.30mm height above board means the header body sits 2.30mm above the PCB surface, leaving 0.70mm of the receptacle height inside the stack.
