M20-7850442

Overview

The Harwin M20-7850442 is an 8-position, dual-row socket strip connector from the M20 series. It features a 2.54 mm pitch and is designed for through-hole mounting with bottom or top entry options. The contacts are gold-plated brass, rated for 3A current. The housing is made of nylon, providing durability for board-to-board and wire-to-board applications.

Feature Summary

• Dual-row configuration for high-density connections
• Gold-plated contacts for reliable conductivity
• Versatile entry orientation support

Applications

• Board-to-board interconnects
• Wire-to-board assemblies
• General electronic circuit connections

Procurement Notes

Verify the specific contact plating and entry orientation against the official datasheet before procurement. Confirm that the through-hole footprint matches the target PCB design. Ensure the 3A current rating meets the application requirements. Check for RoHS compliance status in the latest documentation.

Selection Notes

Select this component when a compact, dual-row socket is required for 2.54 mm pitch systems. Consider the mechanical stability of the through-hole mount versus surface mount alternatives. Evaluate the gold plating benefits against cost constraints for the specific environment.

Part Context

This part belongs to the Harwin M20 series, known for robust performance in demanding environments. The series offers various configurations including different pin counts and mounting styles.
