What it is
The Molex 430451600 is the 16-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, right-angle male header with a 3.00 mm pitch and through-hole solder termination. All 16 positions are loaded. Contacts are tin-plated on both the mating face and the solder-tail side, at a mating-surface thickness of 100.0 µin (2.54 µm). The shroud is 4-wall, which fully encloses the contact阵列 on three sides plus the top — the locking ramp on the header body mates with the receptacle latch to resist vibration pull-out.
Board retention and mounting
Board locks on the header flanks stake into the PCB during placement, anchoring the header against flexing or thermal cycling before solder reflow completes. The tail length is 0.125 inch (3.18 mm). Insulation height is 0.290 inch (7.37 mm); the row spacing matches the mating pitch at 3.00 mm — the Micro-Fit 3.0 receptacle seats flush against the header face without a gap. Right-angle through-hole mounting suits a horizontal board-to-wire board edge — it routes the cable or harness plane parallel to the PCB surface.
Ratings and what they mean for the build
Sourcing and lifecycle
The 430451600 carries an Active lifecycle status and is ROHS3 Compliant — no UL or VDE listing appears in the sourced evidence. Tray packaging is the standard offering for this through-hole header. The connector is quoted to order against BOM quantity; confirm reel availability with your distributor for high-volume placement.
