M20-7871242R

Overview

The M20-7871242R is a dual in-line socket assembly from the Harwin M20 series, designed for surface mount technology. It features a 2.54 mm pitch and consists of two rows with a total of 24 positions. The connector utilizes a bottom entry configuration for mating interface access. Contact plating is specified as tin over nickel to ensure reliable electrical connections. The component is supplied in tape and reel packaging, indicated by the 'R' suffix, facilitating automated pick-and-place assembly processes during manufacturing.

Feature Summary

• Dual row socket assembly design for high-density interconnect applications
• Surface mount termination method compatible with automated SMT production lines
• Bottom entry orientation allows flexible board layout and mating strategies

Applications

• General purpose electronic circuit interconnections
• Board-to-board connection systems requiring surface mount compatibility
• Wire-to-board assemblies utilizing standard pin headers

Procurement Notes

Verify the specific contact plating finish and insulation material grade against current manufacturer datasheets before integration. Confirm that the tape and reel packaging dimensions align with existing pick-and-place equipment specifications. Ensure compliance with relevant environmental directives such as RoHS requirements applicable to the target market. Cross-reference the part number suffix to confirm availability of the reel format variant versus bulk packaging options.

Selection Notes

Select this component when a low-profile, dual-row socket is required for surface mount assembly with a standard 2.54 mm grid. Consider the bottom entry feature if space constraints or mating accessibility dictate non-top-side engagement. Evaluate the tin-plated contacts for cost-effective performance in general-purpose environments rather than high-corrosion scenarios. Ensure the selected housing material meets the thermal and mechanical requirements of the final application environment.

Part Context

This part belongs to the M20 series, a range of connectors known for their reliability in demanding environments. The series offers various configurations including single and double rows with different entry orientations. The M20-7871242R specifically addresses needs for compact, high-pin-count connections on printed circuit boards where surface mounting is preferred over through-hole techniques.
