M20-9991045

Headers, Male Pins Overview

The M20-9991045 is a single-row vertical pin header from the Harwin M20 series, designed for board-to-board and wire-to-board connections. It features 10 positions with a 2.54 mm pitch and utilizes through-hole solder termination. The contacts are made of brass with gold plating to ensure reliable conductivity. Rated for 3A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black UL94V-0 polyamide (nylon) 6T. Key dimensions include a mating pin height of 6.1mm and a tail pin length of 3mm.

Headers, Male Pins Feature Summary

• Gold-plated brass contacts provide high conductivity and corrosion resistance for durable electrical connections.
• Black UL94V-0 polyamide housing offers thermal stability and flame retardancy in demanding environments.
• Vertical single-row design facilitates compact board-to-board and wire-to-board integration.

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board assemblies
• General electronic equipment requiring reliable signal or power transmission

Headers, Male Pins Procurement Notes

Verify the specific contact plating and housing material against the official datasheet, as suffix variations may exist. Confirm that the 3A rating aligns with your application's thermal requirements. Ensure the through-hole footprint matches your PCB design constraints. Cross-reference the RoHS compliance status if environmental regulations apply to your manufacturing process.

Headers, Male Pins Selection Notes

Select this component when a vertical, single-row male header is required for 2.54 mm pitch systems. The gold plating is suitable for applications where low contact resistance and oxidation resistance are critical. Consider the 3A current rating and 105°C maximum operating temperature to ensure compatibility with your system's power and thermal profiles.

Headers, Male Pins Part Context

This part belongs to the M20 series, a widely used rectangular connector family known for its versatility in various electronic applications. The M20 series offers a range of configurations including different row counts, pitches, and termination styles, allowing engineers to standardize on a single connector family for multiple design needs.

Headers, Male Pins Replacement Considerations

Compatible substitutes within the M20 series include M20-9991046, which shares the same form factor but features tin-plated contacts instead of gold. When substituting, verify that the change in contact plating does not impact the electrical performance or corrosion resistance requirements of the specific application.
