The Molex 430451223 is the 12-circuit member of the Micro-Fit 3.0 43045 family — a dual-row, 3.00 mm pitch header with a full 4-wall shroud. The series targets wire-to-board and board-to-cable power interconnect in harness assemblies, and this part's right-angle through-hole body makes it a board-edge power feed or signal pass-through header in control units, DIN-rail enclosures, and panel assemblies.
ROHS3 compliant. No UL, VDE, or IEC certification is cited in the available record — the primary compliance flag is the ROHS3 entry.
The 430451223 mates with the matching Micro-Fit 3.0 receptacle housing in the same 43045 series — the 3.00 mm pitch and 4-wall shroud geometry define the keying and prevent cross-mating with other series at the same pitch.
Board to Cable/Wire, which means this header is the board-side termination in a wire-to-board power interconnect — it receives the matching receptacle housing and its crimp terminal on the wire side.
