M20-7860642R

Overview

The Harwin M20-7860642R is a surface mount receptacle connector from the M20 series, designed for board-to-board applications. It features a single row with six positions and a 2.54 mm (0.100 inch) pitch. The contacts are gold-plated phosphor bronze, ensuring reliable signal transmission. The housing utilizes high-temperature thermoplastic material rated UL94 V-0 for flame resistance. This component supports automated assembly processes and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Surface mount design facilitates automated PCB assembly
• Gold-plated contacts provide corrosion resistance and low contact resistance
• High-temperature thermoplastic housing ensures thermal stability during reflow soldering
• Compact single-row configuration optimizes board space utilization

Applications

• High-density electronic assemblies requiring surface mount connectivity
• Industrial control systems utilizing board-to-board interconnects
• Telecommunications equipment with strict thermal requirements
• Automotive electronics modules needing reliable signal paths

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with standard surface mount placement equipment. Check for any recent product change notifications regarding material composition or dimensional tolerances.

Selection Notes

Select this component for applications requiring robust surface mount connections with high reliability standards. The gold plating offers superior performance in corrosive environments compared to tin variants. Consider the single-row layout for space-constrained designs where vertical stacking is not required. Validate thermal endurance against peak reflow temperatures specified in the datasheet.

Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for durability and precision. The series encompasses various configurations including headers, sockets, and wire housings. The M20-7860642R specifically addresses the need for compact, high-reliability surface mount receptacles in modern electronic manufacturing.

Replacement Considerations

Direct substitutes may include other M20 series variants with matching pin counts and pitch. Verify mechanical dimensions and contact plating specifications before substitution. Cross-reference with Harwin's official obsolescence notices for alternative recommendations.
