M20-9762146

Headers, Male Pins Overview

The Harwin M20-9762146 is a dual in-line (DIL) vertical pin header assembly designed for board-to-board or wire-to-board interconnections. It features a 2.54 mm (0.1 inch) pitch with a 21+21 position configuration, totaling 42 contacts. The connector utilizes a male contact gender with rectangular SQ pin-skt style terminals finished in tin plating. Constructed with a black nylon housing and brass contacts, it supports through-hole solder termination. Electrical specifications include a rated voltage of 750 VAC and a current rating of 3 A per contact. The unit operates within a temperature range of -40°C to +105°C and offers a mechanical durability of 50 mating cycles.

Headers, Male Pins Feature Summary

• Dual in-line vertical architecture providing high-density connectivity with 42 total positions across two rows.
• Tin-plated brass male pins ensure reliable electrical performance and corrosion resistance for repeated mating.
• Nylon insulation housing meets UL94 V-0 flammability standards for enhanced safety in electronic assemblies.

Headers, Male Pins Applications

• High-density board-to-board interconnects in industrial control systems
• Wire-to-board connections in consumer electronics manufacturing
• Signal routing in telecommunications equipment backplanes

Headers, Male Pins Procurement Notes

Verify the specific suffix code against the official Harwin datasheet to confirm terminal plating and housing material variations. Ensure the selected variant matches the required 21+21 DIL configuration and vertical orientation. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the part number with the latest component specification documents to avoid ordering obsolete or discontinued sub-types.

Headers, Male Pins Selection Notes

Select this component when a dual-row vertical header with a standard 2.54 mm pitch is required for robust signal transmission. The 3 A current rating and 750 VAC dielectric strength make it suitable for general-purpose power and data lines. Consider the 50-cycle durability limit for applications requiring frequent disconnection. The straight-through hole mounting style necessitates sufficient PCB clearance for the solder tail length.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of headers and wire housings known for their versatility in mixed-signal environments. The M20 line typically includes various row counts, pitch options, and termination styles. This specific model represents a high-pin-count DIL variant, distinguishing itself from single-row SIL counterparts like the M20-9612146 by offering doubled connectivity density in a vertical footprint.

Headers, Male Pins Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with mating sockets from the same M20 series before considering alternative manufacturers.
