The Hirose DF12(3.0)-36DP-0.5V(86) is a 36-position, 0.50mm pitch board-to-board mezzanine header with outer shroud contacts. It sits in the DF12 series as the variant keyed for a 3mm mated stack height — the "3.0" in the order code is the stacking height, not a pitch modifier. Gold contacts at 8.00µin thickness handle the mating cycles typical of a production board stack, but the thin plating means this is not a high-cycle field-service connector — it is a one-and-done mezzanine interconnect for a fixed assembly.
Obsolete — sourcing through surplus channels
Hirose has marked the DF12(3.0)-36DP-0.5V(86) as Obsolete. No official successor part number is listed in the lifecycle record. Confirm the quantity and lead time at quote; the channel is not a standard stock-holding line.
The outer shroud on the header aligns with the receptacle's inner wall — the pair is not cross-compatible with any other DF12 stack height variant.
Board layout and assembly notes
Surface-mount termination on a 0.50mm pitch, dual-row, 36-position header. The height above board is 2.30mm, and the mated stack height is 3mm — that 0.70mm difference is the receptacle's body height above the opposing board. The board guide feature adds a pair of alignment posts that take shear load during assembly; the solder retention tabs on the sides anchor the part to the board pads. Tape & Reel packaging feeds pick-and-place lines; the Cut Tape option works for prototype builds.
