Product details

Micro-Fit 3.0 Header, 8 Positions, 3.00 mm Pitch

The Molex 430450828 is an 8-position, dual-row header from the Micro-Fit 3.0 43045 series. The 3.00 mm pitch and 0.118" row spacing give it a compact footprint for a 8 A per circuit power interconnect, while the 4-wall shroud protects the male pins during handling and mating. Typical applications include automotive, general-purpose industrial, medical, and telecommunications equipment. The 8 A per circuit rating at 600 V means each pin can carry moderate power — think a small motor drive or a DC power rail inside an enclosure — not just a signal line. The UL94 V-0 LCP housing handles the temperature rise from the full 8 A load without issue.

The through-hole termination (0.125" post length) gives a strong solder joint on the PCB, suitable for wire-to-board harnesses that see cable strain.

Frequently asked questions

What is the pinout of the 430450828 header?

The 430450828 is an 8-position, dual-row header with all positions loaded. The pinout follows the standard Micro-Fit 3.0 dual-row layout — 4 pins per row at 3.00 mm pitch, with 0.118" row spacing. The mating receptacle determines the circuit assignment.

What is the closest alternative to the Molex 430450828?

Within the Micro-Fit 3.0 series, the 430450828 has no direct pin-compatible alternative at the same 8-position count. A 6-position or 10-position sibling would change the circuit count on the BOM. The 430450828 is the correct part for an 8-circuit board-to-wire interconnect at 3.00 mm pitch.
