M20-7880946

Overview

The M20-7880946 is a dual in-line (DIL) socket header manufactured by Harwin Inc., belonging to the M20 series of PCB connectors. This component features a 18-position configuration arranged in two rows, providing a robust board-to-board interconnection solution. It utilizes a standard 2.54 mm pitch and is designed for through-hole mounting with solder pin termination. The contacts are tin-plated to ensure reliable conductivity and corrosion resistance. The housing material is specified as nylon, offering mechanical stability and insulation properties suitable for industrial applications.

Feature Summary

• Dual row DIL socket design for high-density board-to-board connections
• Through-hole solder pin termination for secure PCB mounting
• Tin-plated contacts ensuring reliable electrical performance
• Nylon housing providing structural integrity and insulation

Applications

• Industrial control systems requiring board-to-board connectivity
• Consumer electronics assemblies with space constraints
• Automotive electronic modules needing reliable signal transmission
• Telecommunications equipment interface boards

Procurement Notes

Verify the specific contact count and orientation against project requirements before ordering. Confirm that the tin plating specification meets environmental compliance standards such as RoHS if applicable. Ensure the through-hole footprint on the target PCB matches the 2.54 mm pitch dimensions precisely to avoid assembly issues. Check for any end-of-life status or obsolescence notices from the manufacturer prior to finalizing procurement decisions.

Selection Notes

Select this component when a low-profile, dual-row socket is required for vertical mating with male headers. Consider the thermal operating range and current carrying capacity relative to the application's power distribution needs. Evaluate the mechanical retention provided by the through-hole pins versus surface mount alternatives. Compare against other M20 series variants to determine if single-row or different pitch options better suit the layout constraints.

Part Context

The M20-7880946 is part of Harwin's M20 series, which offers a range of PCB headers and wire housings. This series is known for its compact design and reliability in various electronic environments. The M20 series includes both male and female configurations with varying position counts and row arrangements, catering to diverse interconnection needs in modern electronic devices.

Replacement Considerations

Direct substitutes within the M20 series include other DIL socket headers with matching 2.54 mm pitch and similar position counts, such as M20-788xxxx models. Verify compatibility with mating male headers from the same series to ensure proper fit and function. Cross-reference with equivalent products from other manufacturers only if dimensional and electrical specifications align perfectly.
