The 430450208 in the Micro-Fit 3.0 series
Right-angle SMT termination with a board-lock anchors it against peel forces during wave or IR reflow, a meaningful advantage in any harness panel or vertical-board layout where the connector sees cable-side pull. The four-wall shroud with a locking ramp prevents mis-mating when the matching Micro-Fit receptacle is dropped into the harness — something a single-wall or unshrouded header cannot guarantee on a production floor.
What the ratings mean for selection
The contact plating split is the real selection detail here: gold 30.0 µin (0.76 µm) on the mating face and tin 100.0 µin (2.54 µm) on the solder post. Gold on the mating side preserves low contact resistance through repeated mates — which is what the locking ramp's positive engagement enables — while the thick tin deposit on the post delivers solderability and long-term atmospheric resistance on the PCB pad. This is the standard Micro-Fit 3.0 split for mixed power/signal use, not a special option. 600 V rating is well above typical automotive or industrial board-level rails — it gives you the voltage headroom for in-cabin or industrial control modules without needing to spec a higher-voltage family. The operating window of -40°C to 105°C covers the full automotive thermal range, and the LCP body rated UL94 V-0 satisfies the flammability requirement in most enclosed-module environments.
