What it is
The 430450823: The dual-plating split is the detail that matters most here: 30.0 µin (0.76 µm) gold on the mating face gives wear resistance and low contact resistance at first mate, while the solder-tail side receives 100.0 µin (2.54 µm) tin — a thicker solder-side plate that guards against whisker growth and improves solderability during wave or manual hand assembly. This is a meaningful upgrade over all-tin headers in the same pitch class, and it is the primary reason the 43045 series carries a higher per-contact current ceiling. Current rating is 8 A per circuit at 600 V, and the LCP glass-filled housing carries a UL94 V-0 flammability rating — the combination that makes this series common in industrial control cabinets and automotive harness segments where the board-level connector must survive in a confined, ventilated enclosure.
What the board-fit numbers mean
Right-angle through-hole mount with a board-lock feature that stakes the header to the PCB before wave solder reflow — useful in production where the header must not shift during board handling before the solder reflow pass. The insulation height of 0.290 inches (7.37 mm) governs the keep-out above the PCB surface when the mated assembly sits in the enclosure, and the post length of 0.125 inches (3.18 mm) determines the plated-through-hole depth required on the target board. The shroud is full 4-wall — all four sides of the header cavity are enclosed, which prevents the header from being misoriented during insertion and also provides first-contact protection for the pins during shipping and handling. Combined with the locking ramp on the housing side, the mated pair requires deliberate thumb pressure to unlatch, which is the intended vibration-resistance feature for engine-bay and industrial-floor equipment applications.
Sourcing and lifecycle
The 430450823 carries an Active product status and ROHS3 Compliant designation. It is quoted to order against the BOM quantity — confirm the required volume and lead time through an RFQ before committing to a production schedule. No official successor order code is listed on record; the 8-circuit position count within the 43045 series is the primary differentiator if a cross-reference is required.
