M20-7870946

Overview

The M20-7870946 is a socket assembly from the Harwin M20 series, designed for surface mount technology. It features a dual-in-line configuration with 18 positions arranged in two rows. The connector utilizes a 2.54 mm pitch and accepts bottom entry mating. The contacts are tin-plated to ensure reliable conductivity. This component is intended for board-to-board or cable connections within electronic assemblies requiring robust SMT integration.

Feature Summary

• Dual-row surface mount socket assembly design
• Bottom entry orientation for flexible routing
• Tin-plated contact surfaces for conductivity
• Compatible with standard 2.54 mm pitch headers

Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic equipment assembly
• Industrial control system interfaces

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status via official datasheets. Check for end-of-life notices as availability may be limited. Ensure storage conditions meet manufacturer specifications to prevent oxidation of tin contacts prior to soldering.

Selection Notes

Select this part for applications requiring low-profile SMT sockets with dual-row density. Verify that the mating header matches the 2.54 mm pitch and 18-position count. Consider mechanical retention needs as the push-pull mechanism varies by specific sub-series variant. Ensure PCB footprint aligns with the specified SMT pad layout.

Part Context

Part of the M20 family, known for high-density connectivity solutions. Designed for modern electronics manufacturing processes. Offers reliability in harsh environments due to material selection. Widely used in automotive and industrial sectors for secure signal transmission.

Replacement Considerations

No direct public substitute part numbers are confirmed. Evaluate generic 2.54 mm dual-row SMT sockets with identical pin counts. Verify mechanical dimensions and electrical ratings match before substitution.
