M20-9971045

Headers, Male Pins Overview

The Harwin M20-9971045 is a vertical pin header connector from the M20 series, designed for board-to-board or cable applications. It features a 2.54mm pitch with a 10+10 double in-line configuration, providing 20 positions across two rows. The connector utilizes gold-plated brass contacts and a black polyamide (PA6T) insulator rated UL94 V-0. It supports through-hole solder termination and operates within a temperature range of -40°C to 105°C, carrying a 3A current rating per contact.

Headers, Male Pins Feature Summary

• Double in-line design with 10+10 position layout for high-density connections
• Gold-plated brass contacts ensure reliable signal transmission and corrosion resistance
• Polyamide (PA6T) insulation provides thermal stability and UL94 V-0 flammability rating
• Vertical orientation facilitates standard through-hole PCB mounting

Headers, Male Pins Applications

• Board-to-board interconnections in electronic assemblies
• Cable-to-board wiring harnesses
• Industrial control system interfaces
• Consumer electronics internal connectivity

Headers, Male Pins Procurement Notes

Verify the specific part number M20-9971045 against official Harwin documentation to confirm the 10+10 double in-line configuration and gold plating specifications. Ensure compatibility with mating connectors regarding stack height and pin length. Check for RoHS compliance status as indicated in the manufacturer's datasheet before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a 2.54mm pitch vertical header with 20 positions is required. The double in-line format suits applications needing compact vertical stacking. Consider the PA6T material for environments requiring higher thermal performance compared to standard nylon. Verify that the 3A current rating meets the circuit requirements for all intended signal paths.

Headers, Male Pins Part Context

This connector belongs to the Harwin M20 series, which offers various pin counts and configurations. The M20-9971045 specifically denotes the 10+10 double in-line variant. Similar parts in the series include single-row headers like M20-9991045 and other double-row options, allowing designers to scale pin density while maintaining consistent mechanical and electrical characteristics across the product line.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include other M20 double in-line headers with different pin counts, such as M20-9971046. Cross-series replacements require matching the 2.54mm pitch, 20-position count, and vertical through-hole mounting style. Always verify dimensional tolerances and mating interface compatibility before substituting.
