M20-7871142P

Overview

The M20-7871142P is a dual in-line (DIL) rectangular connector socket assembly manufactured by Harwin Inc. It features a 2.54mm (0.100 inch) pitch with a vertical surface mount termination style designed for bottom entry contact mating. The component is configured as a female socket with two rows of contacts, providing a total of 26 positions. This specific part number variant includes a protective plastic cover to shield the contacts during storage and handling. The housing material is engineered for board-to-board or cable stacking applications, ensuring reliable electrical connectivity in compact electronic assemblies.

Feature Summary

• Vertical surface mount design facilitates automated PCB placement and secure soldering
• Dual in-line configuration supports high-density signal routing with bottom entry mating
• Integrated protective cover maintains contact integrity against contamination and physical damage

Applications

• Board-to-board interconnection systems
• Cable stacking assemblies requiring vertical orientation
• Compact electronic modules utilizing surface mount technology

Procurement Notes

Verify the exact suffix 'P' indicates the inclusion of the protective cover, as this distinguishes it from standard variants without shielding. Confirm the RoHS compliance status through the official datasheet prior to procurement. Ensure the vertical SMT footprint matches the target PCB layout dimensions. Check for any obsolescence notifications from Harwin Inc. regarding this specific part number to avoid supply chain disruptions during production planning.

Selection Notes

Select this component when a vertical orientation is required for DIL connectors with a 2.54mm pitch. The bottom entry mating style is suitable for applications where space above the connector must be minimized. The protective cover feature is essential for environments requiring extended shelf life or protection against mechanical stress before assembly. Compare pin counts and row configurations to ensure compatibility with mating headers.

Part Context

This component belongs to the M20 series of rectangular connectors from Harwin Inc., known for their robust performance in industrial and commercial electronics. The M20 series offers various termination styles and contact arrangements. The M20-7871142P specifically addresses needs for vertical surface mount connections with dual-row capabilities, fitting within the broader category of headers and wire housings designed for reliable signal transmission.

Replacement Considerations

Direct substitutes may include other Harwin M20 series sockets with identical 2.54mm pitch, 26-position count, and vertical SMT termination. Verify that alternative parts also feature the protective cover if environmental protection is critical. Cross-reference mechanical dimensions and thermal ratings to ensure compatibility with existing PCB designs and assembly processes.
