What it mates with
The 430452414: This is the header half — it mounts on the board and accepts the matching Micro-Fit 3.0 receptacle housing, which in turn accepts the standard Micro-Fit 3.0 crimp terminal. The board guide feature aligns the header during assembly. The square pin shape seats the contact positively in the receptacle slot without rotation.
What does not change the decision
The insulation height of 0.390 in (9.91 mm) is within the standard range for the series — it clears most standard LED clusters and ferrite beads on the board. The post length of 0.125 in (3.18 mm) is a standard through-hole gauge; verify board thickness against this reach before specifying. The black housing colour has no functional implication — the LCP material and the UL94 V-0 rating are what matter for high-temperature zones in the enclosure.
