Outer shroud contacts protect the signal pins during assembly and mate with the matching DF12 receptacle. ## Obsolete — Sourcing the DF12D(4.0)50DP0.5V80 Today The DF12D(4.0)50DP0.5V80 is listed as Obsolete, which means Hirose no longer manufactures this exact order code. ## What the 4mm Stack Height and 0.50mm Pitch Mean for the Board Layout That dimension is the z-height constraint — the board-to-board gap after the connector is fully mated. The 0.50mm pitch drives the routing density on both boards: the trace escape from the inner rows requires at least one via per signal under the component keep-out, and the 50 positions in two rows means 25 signals per row.","metaTitle":"Hirose DF12D(4.0)50DP0.5V80 Header, 50 Pos, 0.50mm, Obsolete","metaDescription":"Hirose DF12D(4.0)50DP0.5V80 header, 50 positions, 0.50mm pitch, 4mm stack height, gold contacts.
