M20-7870542

Overview

The Harwin M20-7870542 is a dual-in-line (DIL) socket assembly designed for surface-mount technology. It features a 10+10 position configuration with a 2.54 mm pitch across two rows. The component utilizes bottom entry contacts and employs a tin plating finish on the terminals. This header type is engineered for reliable electrical interconnection in compact electronic assemblies requiring robust SMT integration.

Feature Summary

• Dual-in-line socket assembly architecture supporting surface-mount installation
• Bottom entry contact design facilitating specific board layout configurations
• Tin-plated terminal finish ensuring corrosion resistance and conductivity

Applications

• Surface-mount electronic circuit boards requiring DIL interconnects
• Compact consumer electronics utilizing low-profile headers
• Industrial control modules needing reliable board-to-board connections

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm that the tin plating specification matches your environmental requirements. Ensure PCB footprint dimensions align precisely with the 2.54 mm pitch and dual-row geometry before finalizing procurement orders.

Selection Notes

Select this model when a dual-row, surface-mount female header with bottom entry is required. The 2.54 mm pitch ensures compatibility with standard pin headers. Consider the tin finish for general-purpose applications rather than high-corrosion environments where gold might be preferred. Verify space constraints against the component's physical profile.

Part Context

This component belongs to the Harwin M20 series, a family of rectangular connectors known for their versatility in both through-hole and surface-mount applications. The M20 series offers various row counts and pitches, providing engineers with standardized options for diverse connectivity needs in modern electronic manufacturing.

Replacement Considerations

Check for official end-of-life notifications from Harwin. No direct substitute part numbers are publicly confirmed in the provided documentation. Evaluate alternative M20 series variants or other manufacturers' 2.54 mm DIL SMT sockets if availability is critical.
