It uses a 0.020\" (0.50mm) pitch and two rows of outer shroud contacts, with a mated stacking height of 5mm. This is the footprint and z-height that define the board layout — the 0.50mm pitch keeps the PCB routing dense, while the 5mm stack height sets the clearance between parallel boards. Gold contact finish suits applications requiring repeated mating cycles or operation in mildly corrosive environments. ## Obsolete — Plan for Replacement The DF12(5.0)-20DP-0.5V is officially obsolete. For new designs or BOM maintenance, the manufacturer's recommended replacement is the DF12(5.0)-20DP-0.5V(50), which carries the same 20-position, 0.50mm pitch, 5mm stack height, and gold-plated contacts — a drop-in swap for the original footprint. Do not commit a BOM line to the obsolete code without verifying the replacement fits your assembly process. The outer shroud contacts on the header engage with the receptacle's inner contacts to form the board-to-board connection. Confirm the receptacle order code matches the position count and stacking height before ordering — don't order half a connection. The 0.020\" (0.50mm) pitch and surface-mount termination require a precise PCB footprint — the solder pads must match the 2-row layout exactly to avoid bridging during reflow. The 5mm mated stack height is the clearance between the two PCBs; verify this fits within your enclosure's z-height budget before layout finalization.","metaTitle":"Hirose DF12(5.0)-20DP-0.5V, 20-Pos 0.50mm Header, Obsolete","metaDescription":"Hirose DF12(5.0)-20DP-0.5V 20-position 0.50mm pitch SMT header, 5mm stack height, gold contacts.
