M20-7861646R

Overview

The Harwin M20-7861646R is a 16-position rectangular receptacle connector from the M20 series, designed for board-to-board applications. It features a 2.54mm (0.100 inch) pitch and utilizes surface mount termination. The component supports bottom or top entry configurations and employs tin-plated contacts to ensure reliable electrical connections in compact electronic assemblies.

Feature Summary

• Surface mount receptacle design optimized for high-density PCB layouts
• Dual-entry capability allowing flexible bottom or top cable/connector access
• Tin-plated contact surfaces provide corrosion resistance and stable conductivity

Applications

• Board-to-board interconnections in compact electronic modules
• High-density signal routing in industrial control systems
• Data transmission links in telecommunications equipment

Procurement Notes

Verify the specific suffix 'R' against the official Harwin datasheet to confirm it denotes the correct reel packaging or variant configuration. Ensure the selected part matches the required surface mount orientation and pin count specifications for your assembly.

Selection Notes

Select this component when a low-profile surface mount solution is required for 16-channel interconnects. The 2.54mm pitch ensures compatibility with standard mating headers. Consider the dual-entry feature if space constraints require flexible connection angles.

Part Context

This part belongs to the Harwin M20 series, which provides industrial-standard connectors for demanding environments. The series offers various termination styles and row configurations, balancing robust mechanical performance with compact form factors suitable for modern electronics.

Replacement Considerations

Direct substitutes within the same series include M20-7861646 (tray version). Verify that any alternative maintains identical 2.54mm pitch, 16-position count, and surface mount termination type.
