What the 430452013 is
The Molex 430452013 is the 20-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, shrouded header rated 8 A per circuit at 600 V, with gold-plated mating contacts and tin-plated solder tails in a through-hole kinked-pin termination.
What the key ratings mean
Where this connector class is used
Micro-Fit 3.0 headers are a standard power-interconnect choice across automotive, industrial, medical, and telecommunications applications — anywhere a compact dual-row header must survive high vibration and repeated mate/unmate cycles without the contact fretting that tin-only platings develop over time. The UL94 V-0 glass-filled LCP housing satisfies the flammability requirement common to medical and automotive harness specs.
Production and compliance status
Listed as Active with ROHS3 Compliant status. No EOL or NRND entry on record — quoted to order against BOM quantities on RFQ. The 430452013 mates with the corresponding Micro-Fit 3.0 receptacle housing; the exact matching housing depends on the wire-gauge and locking-latch configuration in the end application — confirm the polarity keying before specifying the mating half.
