M20-7882546

Overview

The M20-7882546 is a rectangular connector socket assembly from the Harwin M20 series. It features a 50-position configuration arranged in a dual in-line (DIL) format with two rows of 25 contacts each. The component utilizes a 2.54 mm pitch and is designed for horizontal through-hole mounting on printed circuit boards. The housing material is specified as nylon, providing structural integrity and insulation. The female sockets are terminated with tin plating to ensure reliable electrical contact. This part is classified under headers and wire housings, intended for board-to-board interconnection applications requiring high-density pin arrangements.

Feature Summary

• Dual in-line configuration supporting high-density signal routing
• Horizontal orientation optimized for specific PCB layout constraints
• Through-hole termination method ensuring mechanical stability

Applications

• High-density board-to-board interconnect systems
• Industrial control panel wiring harnesses
• Telecommunications equipment backplanes

Procurement Notes

Verify the exact pin count and row arrangement against the official datasheet before integration. Confirm that the horizontal mounting style aligns with the mechanical design of the target PCB. Ensure the tin-plated contacts meet the corrosion resistance requirements of the operating environment. Check for any specific handling instructions related to the nylon housing during soldering processes.

Selection Notes

Select this component when a 50-pin DIL interface is required in a horizontal form factor. The 2.54 mm pitch is standard for general-purpose electronics but requires precise alignment during assembly. Consider the mechanical stress on through-hole joints if the connector will be subjected to vibration. Evaluate the tin plating suitability against potential galvanic corrosion risks with mating pins.

Part Context

This part belongs to the Harwin M20 series, which focuses on robust rectangular connectors for demanding environments. The M20-788 variant specifically addresses horizontal mounting needs within the broader M20 family. It complements other vertical and angled options by providing a low-profile solution for space-constrained designs requiring dense I/O connections.

Replacement Considerations

Direct substitutes must match the 50-position DIL layout, 2.54 mm pitch, and horizontal through-hole termination. Verify compatibility with existing PCB footprints and mating header dimensions. Cross-reference RoHS compliance and material specifications to ensure equivalent performance characteristics.
