M20-7890742

Overview

The M20-7890742 is a 7-position socket connector from the Harwin M20 series, designed for surface-mount technology. It features a right-angle configuration with a 2.54 mm (0.1 in) pitch and dual rows. The contacts are gold-plated to ensure reliable signal transmission. This component is classified as obsolete and is no longer in active production by the manufacturer.

Feature Summary

• Right-angle surface-mount design for compact board integration
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Dual-row socket assembly compatible with standard header pins

Applications

• Obsolete electronic assemblies requiring legacy replacement
• Right-angle PCB interconnects in discontinued consumer devices
• Specialized industrial equipment maintenance using existing M20 series designs

Procurement Notes

This component is officially listed as obsolete by Harwin Inc. Availability is restricted to remaining stock from third-party distributors or surplus markets. Buyers should verify the authenticity of sources carefully, as genuine new-old-stock units may be scarce. Procurement requires confirmation of part condition and origin due to the end-of-life status.

Selection Notes

Engineers replacing this obsolete part must evaluate mechanical compatibility, specifically the right-angle orientation and 2.54 mm pitch. Alternative selection should focus on current M20 series variants or equivalent right-angle sockets from other manufacturers that match the pin count and contact plating requirements. Thermal and electrical ratings must align with original system specifications.

Part Context

The M20 series represents Harwin's high-density interconnect solutions, known for robust performance in space-constrained applications. The M20-7890742 specifically utilizes a socket housing with gold contacts, suitable for repeated mating cycles. Its right-angle form factor allows for vertical stacking or edge-board connections, distinguishing it from straight-header variants within the same product family.

Replacement Considerations

M20-7890742 is obsolete; no direct official substitute exists. Consider M20-7890742R if reel availability permits, or generic 7-pos 2.54mm right-angle SMT sockets.
