M20-9774046

Headers, Male Pins Overview

The Harwin M20-9774046 is a single-row vertical pin header from the M20 series, featuring 40 positions with a 2.54 mm pitch. Designed for through-hole mounting, it utilizes brass contacts plated with gold high temperature (HT) finish and a black nylon housing. The connector supports a current rating of 3 A and a voltage rating of 750 V. It operates within a temperature range of -40°C to +105°C and includes a mating pin length of 5.8 mm.

Headers, Male Pins Feature Summary

• Gold high temperature plating ensures reliable performance in demanding thermal environments.
• Nylon housing provides structural integrity and electrical insulation.
• Single-row vertical configuration facilitates standard board-to-board or wire-to-board connections.

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board assemblies
• General electronic equipment requiring robust thermal stability

Headers, Male Pins Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm RoHS compliance status via the specific product documentation. Ensure storage conditions maintain contact integrity prior to assembly. Validate that the gold HT plating specification matches design requirements for high-temperature soldering processes.

Headers, Male Pins Selection Notes

Select this part when a single-row, 40-position header with high-temperature gold plating is required. The 2.54 mm pitch is standard for general-purpose electronics. Consider the through-hole mounting style and vertical orientation for PCB layout compatibility. Verify that the 3 A current rating and 750 V voltage rating meet circuit specifications.

Headers, Male Pins Part Context

This component belongs to the Harwin M20 series, which offers versatile 2.54 mm pitch connectors. The series includes various row counts, orientations, and plating options. The M20-977xxx suffix typically denotes single-row vertical headers with specific pin heights and plating types, designed for high-reliability applications.

Headers, Male Pins Replacement Considerations

M20-9773946 is a similar single-row vertical pin header but features tin plating instead of gold HT. Verify that the lower cost tin option meets the thermal and corrosion resistance requirements if substituting.
