M20-7873146

Overview

The M20-7873146 is a dual in-line (DIL) female socket assembly from the Harwin M20 series, designed for surface mount technology. It features a 62-position configuration with a standard 2.54 mm pitch. The connector utilizes a tin-plated contact finish to ensure reliable electrical performance. This component is engineered for bottom or top entry applications, providing flexibility in board layout and mating orientation. It serves as a robust interconnection solution within the broader M20 header and wire housing product line.

Feature Summary

• Dual in-line female socket design for versatile board integration
• Surface mount termination method for automated assembly processes
• Tin-plated contacts for dependable signal transmission
• Supports both bottom and top entry mating orientations

Applications

• General purpose electronic interconnections
• Industrial equipment control panels
• High-voltage circuit board assemblies

Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in production. Sourcing new units may be restricted to existing stock or third-party distributors. Verification of part authenticity and storage conditions is critical due to the end-of-life status. Engineers should prioritize immediate replacement strategies to mitigate supply chain risks associated with discontinued components.

Selection Notes

Designers requiring this specific 62-position configuration must consider the obsolescence status when planning long-term projects. Alternative solutions within the M20 series or other compatible high-density connectors should be evaluated. Ensure that any substitute maintains the required 2.54 mm pitch and surface mount compatibility to preserve mechanical and electrical integrity in the final assembly.

Part Context

The M20 series represents a range of PCB headers and wire housings known for compact design and reliability. This specific model belongs to the female socket category, offering high-density connectivity options. The series is widely recognized for its durability and suitability for demanding industrial environments, supporting various mounting styles and contact configurations.

Replacement Considerations

M20-7873146 is obsolete. Potential substitutes include M20-7873142 or M20-7873144 if pin counts differ, though exact 62-position equivalents may require cross-referencing current Harwin catalogs for active inventory.
