M20-7861142R

Overview

The M20-7861142R is a rectangular connector from the Harwin M20 series, classified as a socket assembly header. It features a 2.54 mm (0.1 in) pitch and is designed for surface mount technology with bottom entry configuration. The component consists of 11 positions arranged in a dual in-line (DIL) format across two rows. It utilizes tin plating on the contacts to ensure reliable mating performance. This specific part number variant includes a 'R' suffix, which typically denotes a reel packaging format for automated assembly processes.

Feature Summary

• Surface mount design with bottom entry orientation for PCB integration
• Dual in-line socket assembly structure accommodating male pins
• Tin-plated contact surfaces for corrosion resistance and conductivity

Applications

• General electronic circuit board interconnections
• Automated surface mount assembly lines
• Industrial control system signal routing

Procurement Notes

Verify the exact meaning of the 'R' suffix against the official Harwin datasheet, as it may indicate specific packaging or handling characteristics distinct from the standard M20-7861142. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the selected distributor provides traceable documentation for the component batch.

Selection Notes

Select this component when a low-profile, surface-mount female connector is required for 11-position applications. Compare against through-hole alternatives if mechanical robustness during insertion is critical. Verify that the PCB footprint matches the specific SMT pad layout defined in the M20 series drawing.

Part Context

This component belongs to the Harwin M20 series, a widely used family of rectangular connectors known for their versatility in board-to-board and wire-to-board connections. The M20 series offers various configurations including headers, sockets, and cable assemblies in both through-hole and surface mount formats.

Replacement Considerations

M20-7861142 serves as the primary non-reel equivalent. Cross-reference with other M20 series variants for different pin counts or plating options if specifications do not align perfectly.
