M20-8773146

Headers, Male Pins Overview

The Harwin M20-8773146 is a 31-position single-row pin header connector belonging to the M20 series. It features a 2.54 mm (0.1 inch) pitch and is designed for surface mount technology (SMT) installation. The connector utilizes straight termination with tin-plated contacts made from brass, ensuring reliable electrical performance. Rated for 3 A current and compatible with standard PCB densities, this component supports board-to-board or wire-to-board applications within an operating temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Surface mount design optimized for automated pick-and-place assembly processes
• Single row configuration providing compact vertical interconnection solutions
• Tin-plated brass contacts ensure corrosion resistance and stable conductivity

Headers, Male Pins Applications

• Board-to-board interconnections in high-density electronic assemblies
• Wire-to-board connections requiring surface mount reliability
• Industrial control systems and consumer electronics manufacturing

Headers, Male Pins Procurement Notes

Verify the specific ordering suffix to confirm surface mount compatibility and contact plating type. Ensure the selected variant matches the required position count and pitch specifications for your PCB layout. Check RoHS compliance status if environmental regulations apply to your production environment. Confirm availability as lead times may vary based on manufacturing schedules.

Headers, Male Pins Selection Notes

Select this connector when surface mount assembly is preferred over through-hole methods to reduce profile height. The single-row format suits applications with limited lateral space but sufficient vertical clearance. Consider the tin plating for general purpose use; gold plating options exist for higher corrosion resistance requirements. Verify that the 31-position count aligns precisely with circuit signal routing needs.

Headers, Male Pins Part Context

This component is part of the Harwin M20 series, a widely used family of rectangular connectors known for their robust mechanical design and versatility. The M20 series offers various configurations including through-hole and surface mount options in single and double rows. This specific model represents the surface mount variant within the series, catering to modern SMT production lines.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M20-8773046P (30 positions) and M20-8773246P (32 positions). These alternatives share identical pitch, mounting style, and contact material characteristics. Ensure the replacement maintains the same row count and orientation to fit existing PCB footprints without modification.
