The 0.50mm pitch (0.020\") drives a dense footprint — trace escape from inner rows needs micro-vias or tight neck-downs on the PCB. Outer shroud contacts protect the mating interface during blind-mate assembly. ## Board Layout Fit — SMT, Board Guide, Solder Retention The board guide aligns the header during reflow, and the solder retention pads anchor the part against shear from cable or card insertion. Height above board is 2.80mm (0.110\"), so the total Z-budget after stacking to the mating receptacle is the 3.5mm stack height — no extra clearance needed above the header body. ## Obsolete — Last-Time Buy or Cross to Current DF12 Series","metaTitle":"Hirose DF12(3.5)-40DP-0.5V(86) Header, 40 Pos, 0.50mm Pitch","metaDescription":"Hirose DF12(3.5)-40DP-0.5V(86) 40-position header, 0.50mm pitch, 3.5mm stack height.
