M20-9762442

Headers, Male Pins Overview

The Harwin M20-9762442 is a surface-mount pin header assembly from the M20 series, designed for board-to-board or cable connections. It features a 2.54 mm (0.100 inch) pitch with 40 positions arranged in two rows. The connector utilizes square brass contacts with gold plating on the mating interface and tin plating on the tail for soldering. Rated for 3 A per contact at 250 V, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T) with a UL94 V-0 flammability rating. It employs a push-pull locking mechanism and has an insulation height of 2.54 mm.

Headers, Male Pins Feature Summary

• Surface-mount design with push-pull locking mechanism for secure retention
• Dual-row configuration with gold-plated mating contacts for reliable signal transmission
• Polyamide insulation material rated UL94 V-0 for enhanced fire safety

Headers, Male Pins Applications

• High-density board-to-board interconnects
• Cable-to-board assemblies requiring surface-mount termination
• Industrial control systems operating in extreme temperatures

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact plating and tail configuration. Confirm that the surface-mount footprint matches your PCB layout requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure compatibility with automated pick-and-place equipment due to the component's profile.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required for rigid board-to-board applications. The dual-row format maximizes I/O density within a limited footprint. Consider the push-pull feature if vibration resistance is critical. Verify that the 2.54 mm pitch aligns with your mating connector specifications. Evaluate thermal management needs given the 105°C maximum operating temperature.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, which offers various configurations including vertical, horizontal, and right-angle headers. The M20 series is known for its compact size and robust mechanical performance. Similar parts in the series may differ in row count, position number, or mounting style. Always cross-reference the full datasheet for dimensional tolerances and mating partner recommendations.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 40-position count, dual-row layout, and surface-mount termination. Verify that any alternative maintains the same current rating and voltage specification. Ensure the replacement supports the required push-pull locking mechanism if present in the original design.
