Product details

Right-Angle Power Header for Wire Harness Interconnects

The Molex 430452421 is a 24-circuit, dual-row, right-angle through-hole header from the Micro-Fit 3.0 43045 series. It connects a PCB to a wire harness, mating with the corresponding Micro-Fit 3.0 receptacle housing and crimp terminals. The 3.00 mm pitch and 0.118" row spacing define the board footprint, while the 8 A per circuit rating at 600 V suits it for moderate-power distribution in automotive, industrial, medical, and telecom equipment.

Key Features for Assembly and Reliability

Frequently asked questions

What is the pitch of Molex 430452421?

The mating pitch is 0.118" (3.00 mm), with the same 0.118" row spacing between the two rows of pins.

What is the current rating of 430452421?

Each contact is rated 8 A at 600 V. The tin plating on the mating surface means this rating applies for moderate-cycle applications typical of harness interconnects.

Is 430452421 RoHS compliant?

Yes, the part is ROHS3 compliant.
