M20-9971145

Headers, Male Pins Overview

The M20-9971145 is a vertical pin header connector from the Harwin M20 series, designed for through-hole mounting. It features a 22-position configuration with a 0.100-inch (2.54mm) pitch and dual rows. The connector utilizes square male pins made of brass with tin plating on both mating and tail sections. Insulation is provided by black PA6T nylon rated UL94 V-0, supporting a working temperature range of -40°C to 105°C. Each contact is rated for 3A current.

Headers, Male Pins Feature Summary

• Push-pull locking mechanism ensures secure connection stability
• Cuttable design allows for flexible circuit board layout adaptation
• Tin-plated brass contacts provide reliable electrical conductivity

Headers, Male Pins Applications

• Board-to-board interconnections
• Cable-to-board connections
• General electronic assembly requiring high-density routing

Headers, Male Pins Procurement Notes

Verify component status as this specific part number may be discontinued or subject to change. Confirm availability through authorized distributors only. Ensure compatibility with mating sockets regarding pin length and insulation height. Check for RoHS compliance documentation if required for specific regulatory standards.

Headers, Male Pins Selection Notes

Select this connector when a 22-position dual-row header is required with tin-plated contacts. Consider the M20 series for its push-pull locking feature and cuttable format. Verify that the 3A per contact rating meets circuit requirements. Ensure PCB layout accommodates the specified 2.54mm pitch and row spacing.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series of rectangular connectors. The series is characterized by its push-pull locking system and versatile form factors including headers and sockets. The M20-9971145 specifically represents a dual-row, 22-position variant within this family, utilizing standard 2.54mm spacing for broad industry compatibility.

Headers, Male Pins Replacement Considerations

M20-9971146 is a similar 22-position dual-row header but uses gold plating instead of tin. Verify plating requirements before substitution. Other M20 series variants with different pin counts may serve as alternatives if position count differs.
