Product details

The Molex 430452213 is a 22-position, dual-row header from the Micro-Fit 3.0 43045 series. The 8 A per circuit rating means each contact carries moderate power — think distribution within a harness, not a signal line.

Shrouded and locked for vibration resistance

This combination suits it for automotive, industrial, and telecom environments where vibration could otherwise work a connection loose.

Through-hole mounting with kinked solder tails (0.125" post length) gives a robust mechanical anchor to the PCB. The brass contacts are tin-plated on the solder side (100.0 µin) for good wetting, while the gold mating surface handles repeated connect-disconnect cycles.

Frequently asked questions

What is the exact pitch and number of positions of the Molex 430452213?

The 430452213 has 22 positions on a 3.00 mm pitch, arranged in two rows with 0.118" row spacing.

What is the mating connector for the 430452213?

This header mates with a Micro-Fit 3.0 receptacle housing that accepts the matching crimp terminals. The locking ramp on the header engages the latch on the receptacle side for vibration-resistant retention.

Is the 430452213 RoHS compliant?

Yes, it is ROHS3 compliant.

What is the closest pin-compatible alternative to the 430452213?

Within the Micro-Fit 3.0 series, the 430452213 is a specific 22-position, dual-row, through-hole header with gold mating contacts. A lower-position sibling (e.g. 16-position) shares the same 3.00 mm pitch and footprint class but matches a different circuit count. No exact pin-compatible drop-in replacement exists outside the same part number — verify your BOM position count before substituting.
