Product details

Board-to-Wire Power Header for Automated Assembly

The Molex 430452419 is a 24-circuit, dual-row header from the Micro-Fit 3.0 43045 series, designed for board-to-wire power distribution.

Positioning in the Micro-Fit 3.0 Family

This 24-position header sits at the higher end of the Micro-Fit 3.0 dual-row range. Against the 12-position 430451210 at the same 3.00 mm pitch and 8 A rating, the 430452419 doubles the circuit count for applications needing more I/O on the same footprint pitch. The choice between them comes down to the BOM position count — the board footprint, current per circuit, and mating receptacle family are identical, so the swap is a straight position-count decision.

Frequently asked questions

Where can I buy the Molex 430452419 and how do I get a price?

Submit an RFQ to confirm current availability and pricing for your BOM quantity.

What is the pitch of the Molex 430452419?

The pitch is 3.00 mm (0.118") on both the position spacing and the row-to-row spacing, matching the standard Micro-Fit 3.0 footprint.

Is 430452419 a surface mount or through-hole connector?

It is a surface-mount (SMT) header with solder retention features, designed for reflow soldering — not through-hole wave soldering.

What is the current rating of the Molex 430452419?

The header is rated 8 A per circuit at 600 V, with the current limit set by the temperature rise of the LCP housing at the 3.00 mm pitch.

Is the 430452419 compatible with standard Micro-Fit 3.0 receptacles?

Yes, it mates with the matching Micro-Fit 3.0 receptacle housings that accept the 43045-series crimp terminals. The locking ramp and 4-wall shroud are keyed to the receptacle interface.
