Product details

Board-to-Wire Power Header for Harness Assemblies

The Molex 430451411 is a 14-position, dual-row male header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power interconnects. Rated at 8 A per circuit with a 600 V voltage rating, each power blade carries enough current for a moderate DC rail or a bank of I/O. The tin-plated solder tails (100.0 µ") handle the reflow side without issue.

This header mates with the matching Micro-Fit 3.0 receptacle housing (sold separately), which accepts the standard Micro-Fit 3.0 crimp terminals for 20-24 AWG wire. Termination is solder-only — the SMT tails are designed for reflow assembly. The solder retention feature holds the part in place during the solder paste reflow, preventing tombstoning or skew from the shear force of a cable strain. No press-fit option exists for this variant.

Frequently asked questions

Where can I buy molex 430451411?

Availability and current pricing are confirmed at the time of quote — submit an RFQ for your BOM quantity.

What is the mating connector for 430451411?

The 430451411 mates with a Micro-Fit 3.0 receptacle housing that accepts standard Micro-Fit 3.0 crimp terminals. The exact receptacle order code depends on your circuit count and wire gauge — match the 14-position count and 3.00 mm pitch to the receptacle side.

Is 430451411 RoHS compliant?

Yes, the 430451411 is ROHS3 compliant.

What is the current rating of molex 430451411?

The header is rated 8 A per circuit at the stated voltage rating of 600 V. The 8 A figure is per-contact at the temperature rise limit of the housing; derate above 105°C per the manufacturer's curve.

Does 430451411 have a locking ramp?

Yes, the header has a locking ramp as part of its shrouded 4-wall design. It provides a positive latch with the mating receptacle for vibration-resistant retention.
