No official successor part number is recorded in the lifecycle entry. At 0.50 mm pitch, the trace escape from the inner rows requires either micro-vias or a tight via-in-pad strategy — this is not a pitch that routes easily on a two-layer board. The board guide eases hand placement during assembly, and the solder retention pads on the sides add shear strength against the lateral force from a cable or mezzanine card during handling.","metaTitle":"Hirose DF12(4.0)-36DP-0.5V(81) 36-Pos 0.50mm Header","metaDescription":"Hirose DF12(4.0)-36DP-0.5V(81) 36-position 0.50mm pitch header, 4mm stack height, SMT.
