M20-9750342

Headers, Male Pins Overview

The Harwin M20-9750342 is a single-row pin header from the M20 series, designed for board-to-board or wire-to-board connections. It features a 2.54 mm (0.1 in) pitch and contains three positions. The connector utilizes brass contacts with gold plating for reliable signal transmission. It is rated for 3 A current and supports voltages up to 750 V. The housing is constructed from black nylon, offering UL94 V-0 flammability rating. Designed for through-hole mounting, it ensures secure soldering to printed circuit boards.

Headers, Male Pins Feature Summary

• Single-row configuration with 2.54 mm pitch for standard spacing requirements
• Gold-plated brass contacts ensure durable electrical connectivity
• Black nylon insulation provides thermal stability and flame resistance
• Through-hole termination method guarantees robust mechanical fixation

Headers, Male Pins Applications

• General electronic interconnects requiring low-profile headers
• Industrial control panels and instrumentation modules
• Consumer electronics assembly with standard pin counts
• Test and measurement equipment connection points

Headers, Male Pins Procurement Notes

Verify the specific contact plating thickness and insulation material grade against the official Harwin datasheet before integration. Confirm that the through-hole footprint matches the target PCB design rules. Ensure environmental compliance documentation aligns with project requirements. Cross-reference the part number suffix to confirm exact orientation and terminal type specifications.

Headers, Male Pins Selection Notes

Choose this component when a single-row, three-position header is required with high reliability standards. The gold plating offers superior corrosion resistance compared to tin alternatives. Consider the 750 V rating for applications involving higher potential differences. Verify that the 3 A current capacity meets the circuit load requirements without excessive heating.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used family of rectangular connectors known for their versatility. The M20 line includes various row counts, pitches, and mounting styles. This specific model represents a compact, single-row solution suitable for dense packaging needs while maintaining standard 2.54 mm spacing compatibility with other industry-standard components.

Headers, Male Pins Replacement Considerations

M20-9750346 is a documented substitute within the same series, featuring tin plating instead of gold. Verify that the change in contact material does not impact long-term corrosion performance in the intended environment. Ensure mechanical dimensions remain identical to avoid PCB layout modifications.
