428203214

Headers, Male Pins Overview

The Molex 42820-3214 is a Mini-Fit Sr. series PCB mount plug connector featuring a right-angle, single-row header configuration with three positions. Designed for high-power applications, it utilizes a 10.00mm (0.394 inch) pitch and supports up to 600V voltage and 40A current ratings. The component includes a polarized housing to prevent mismating and employs silver-plated contacts with a dual-beam female terminal design for reliable performance. It is engineered for 1.57mm thick printed circuit boards with a 3.50mm tail length.

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Molex datasheet to confirm pin count, plating type, and orientation. Ensure compatibility with mating receptacles from the same Mini-Fit Sr. series. Check for any recent product lifecycle changes or obsolescence notices directly from the manufacturer before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a high-current, right-angle wire-to-board solution is required. The 10mm pitch accommodates larger gauge wires suitable for power transmission. Confirm that the target PCB thickness matches the 1.57mm specification and that the application environment does not exceed the 600V/40A ratings.

Headers, Male Pins Part Context

This part belongs to the Mini-Fit Sr. family, a compact power connector system designed for demanding environments. The series offers robust mechanical retention and high current carrying capacity, making it suitable for applications requiring reliable power delivery in space-constrained designs across automotive and industrial sectors.

Headers, Male Pins Replacement Considerations

Direct replacements must match the 10mm pitch, 3-position count, right-angle orientation, and Mini-Fit Sr. interface. Verify that substitute headers maintain identical polarization features and current/voltage ratings to ensure functional equivalence without redesigning the PCB footprint.
