M20-9972945

Headers, Male Pins Overview

The Harwin M20-9972945 is a vertical pin header from the M20 series, designed for board-to-board and wire-to-board interconnections. It features a 2.54 mm pitch with 29 positions arranged in a single row. The connector utilizes brass contacts with gold plating for reliable signal transmission. Rated for 3 A current and 750 V voltage, it operates within a temperature range of -40°C to 105°C. The nylon housing ensures UL94 V-0 flammability rating, while through-hole solder termination provides secure mechanical mounting.

Headers, Male Pins Procurement Notes

Verify the specific contact count and plating type against official datasheets before procurement, as suffix variations may alter specifications. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the selected variant matches the required voltage and current ratings for the target application environment to prevent performance issues.

Headers, Male Pins Selection Notes

Select this component when a single-row, vertical header with gold contacts is required for high-reliability applications. Consider the 2.54 mm pitch compatibility with mating connectors. Evaluate the thermal operating range and flammability rating against environmental constraints. Compare against tin-plated alternatives if cost reduction is prioritized over corrosion resistance.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used line of rectangular connectors known for robust performance. The M20 series offers various configurations including single and double rows with different contact counts. This specific model represents a single-row option within that extensive family, providing standardized spacing for general-purpose interconnect needs.

Headers, Male Pins Replacement Considerations

M20-9972946 is a confirmed substitute offering identical mechanical dimensions and pin count but with tin plating instead of gold. Verify that the change in contact material does not impact the specific application requirements regarding conductivity or environmental exposure.
