M20-7890342

Overview

The Harwin M20-7890342 is a 3-position female socket connector from the M20 series, designed for surface mount technology. It features a single in-line (SIL) configuration with a 2.54 mm pitch. The contacts are gold-plated with tin termination to ensure reliable signal transmission and solderability. This component serves as a receptacle for mating with male headers, providing a secure electrical connection in compact electronic assemblies.

Feature Summary

• Surface mount design for automated PCB assembly
• Gold-plated contacts with tin termination for enhanced conductivity
• Single in-line housing format for space-efficient layouts

Applications

• Compact consumer electronics interconnects
• Industrial control board connections
• Medical device signal routing

Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status prior to integration. Ensure storage conditions maintain contact integrity. Check for obsolescence notices as availability may be limited. Validate mechanical fit against target PCB footprint specifications.

Selection Notes

Select this part for applications requiring low-profile surface mount connectivity. The 2.54 mm pitch ensures compatibility with standard header systems. Gold plating offers superior corrosion resistance compared to tin-only options. Consider thermal management requirements during reflow soldering processes.

Part Context

Part of the Harwin M20 family, known for high-density interconnect solutions. Designed for modern electronics manufacturing trends favoring miniaturization. Complements other M20 series components for complete system integration.

Replacement Considerations
