M20-9761142

Headers, Male Pins Overview

The M20-9761142 is a vertical pin header from the Harwin M20 series, designed for board-to-board or wire-to-board connections. It features a 2.54 mm (0.100 inch) pitch and a single row configuration with 11 positions. The connector utilizes brass contacts with gold plating on the mating interface and tin plating on the tail, housed in black polyamide (PA6T) insulation. Rated for 3A current and 250V voltage, it supports surface mount installation via solder termination. The component operates within a temperature range of -40°C to +105°C and meets UL94 V-0 flammability standards.

Headers, Male Pins Feature Summary

• Push-pull locking mechanism ensures secure mating retention
• Square contact shape provides stable alignment during insertion
• Cuttable design allows for flexible circuit board layout adaptation

Headers, Male Pins Applications

• Board-to-board interconnects in industrial control systems
• Wire-to-board connections in automotive electronics
• Signal routing in consumer electronic devices

Headers, Male Pins Procurement Notes

Verify the specific suffix against the official Harwin datasheet to confirm exact pin count and packaging format. Ensure compatibility with automated pick-and-place equipment if SMD assembly is required. Confirm that the gold plating thickness meets the application's wear resistance requirements. Cross-reference the UL94 V-0 rating with local safety regulations for the target market.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is needed for signal-level applications. The 2.54 mm pitch offers a balance between spacing and density. Consider the push-pull feature for applications requiring frequent mating cycles. Verify that the 3A per contact rating suffices for the intended load without derating due to ambient temperature constraints.

Headers, Male Pins Part Context

This part belongs to the M20 series, known for its compact form factor and robust mechanical performance. The series includes various pin counts and configurations, all sharing the same 2.54 mm pitch and material specifications. The M20-9761142 specifically addresses the need for an 11-position header in space-constrained designs.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M20 series headers with identical pitch and row count, such as M20-9761146. Generic equivalents must match the 2.54 mm pitch, 11-pin count, and SMD mounting style to ensure physical and electrical compatibility.
