M20-7870646

Overview

The M20-7870646 is a dual-in-line socket assembly from the Harwin M20 series, designed for surface mount technology. It features a 12-position configuration arranged in two rows of six contacts each, with a standard 2.54 mm (0.1 inch) pitch. The connector utilizes bottom entry receptacles terminated with tin plating on the contact interfaces. This component is engineered for reliable board-to-board interconnections, offering a compact footprint suitable for high-density PCB layouts while maintaining industrial-grade performance standards.

Feature Summary

• Dual-in-line socket assembly design facilitates secure board-to-board connections
• Surface mount termination enables automated pick-and-place manufacturing processes
• Bottom entry orientation supports efficient PCB routing and space optimization

Applications

• Board-to-board interconnects in industrial control systems
• Signal transmission modules within telecommunications equipment
• Consumer electronics assemblies requiring compact mounting solutions

Procurement Notes

Verify end-of-life status before finalizing designs, as this specific part number may be discontinued or subject to limited availability. Confirm that the tin-plated contact finish aligns with your environmental and corrosion resistance requirements. Ensure compatibility with standard SMT reflow profiles and check for any recent product change notifications regarding material substitutions or packaging variations.

Selection Notes

Select this component when a low-profile, surface-mount female connector is required for dense circuit board arrangements. The 2.54 mm pitch ensures compatibility with standard header pins, while the dual-row layout maximizes I/O capacity within constrained spatial limits. Consider the tin plating for general-purpose applications where gold plating is unnecessary, balancing cost-effectiveness with adequate conductivity.

Part Context

This part belongs to the extensive M20 series by Harwin Inc., a widely recognized line of rectangular connectors known for their robust mechanical design and reliability. The series encompasses various configurations including through-hole and surface mount options, catering to diverse electronic integration needs across multiple industries. The M20-7870646 specifically addresses the demand for compact, solderable female connectors in modern electronics manufacturing.

Replacement Considerations

M20-7871046 is a documented related product within the same series, featuring a 20-position configuration. Verify pin count and physical dimensions before substitution, as these differ significantly from the 12-position M20-7870646.
