M20-7810245R

Overview

The M20-7810245R is a surface mount socket assembly from the Harwin M20 series. It features a 4-position configuration arranged in a double-row layout with a 2.54 mm (0.1 inch) pitch. The connector utilizes gold plating on the contacts and supports both bottom and top entry wire configurations. Designed for board-to-board or board-to-wire applications, it offers secure latching mechanisms suitable for high-reliability environments.

Feature Summary

• Surface mount construction for automated PCB assembly
• Double-row geometry with jackscrew fixing options
• High-temperature UL 94V-0 rated housing material
• Gold-plated copper alloy contacts for corrosion resistance

Applications

• Board-to-board interconnection systems
• Wire-to-board harness connections
• Industrial control module interfaces
• Telecommunications equipment backplanes

Procurement Notes

Verify component authenticity through authorized Harwin distributors to ensure compliance with RoHS standards and original manufacturing specifications. Confirm that the specific ordering suffix matches the required contact plating and housing color variants. Check current lifecycle status as availability may vary by region due to supply chain constraints or end-of-life notifications.

Selection Notes

Select this part when a low-profile, double-row surface mount socket is required for dense circuit layouts. Ensure the design accommodates the 2.54 mm pitch and straight mounting orientation. Verify that the application environment does not exceed the thermal ratings of the UL 94V-0 housing material. Consider the mechanical retention provided by the jack screw feature if vibration resistance is critical.

Part Context

This component belongs to the M20 series, which provides a range of header and socket solutions for compact electronic designs. The series emphasizes reliability through robust mechanical locking and high-temperature performance. The M20-7810245R specifically addresses needs for multi-contact surface mount interfaces requiring precise alignment and durable electrical connections.

Replacement Considerations

Direct substitutes within the same series include other M20 double-row sockets such as M20-7862442, though pin counts and entry styles differ. Cross-series replacements require matching pitch, row count, and mounting type. Verify that alternative components support the same current rating and voltage specifications before integration.
