30-position, 0.50 mm pitch mezzanine header — what it does
The DF12(4.0)30DP0.5V(80: This is a Hirose DF12 series header with outer shroud contacts, 30 positions in two rows at 0.50 mm pitch. The gold contact finish and surface-mount termination suit it for production runs where corrosion resistance and reflow assembly are standard.
Obsolete — sourcing path and replacement planning
No official successor is listed, so any replacement must be evaluated against the 30-position, 0.50 mm pitch footprint and the 4 mm stacking height. We source this connector per RFQ — no stock is held. For a BOM line that cannot be redesigned, a last-time buy or scavenged inventory may be the only path. If you are planning a new build, consider a current Hirose DF12 variant or a cross-shopped alternative with matching pitch and stack height.
The two-row, 30-position layout is mirrored on the receptacle side — confirm the receptacle order code before committing the BOM. The surface-mount pads and board guide geometry are specific to the DF12 footprint. A direct PCB layout swap to a different series requires a board respin.
