M20-8772142

Headers, Male Pins Overview

The M20-8772142 is a surface-mount header connector from the Harwin M20 series, featuring 21 positions with a 2.54mm pitch. It utilizes brass contacts with gold plating for mating and tin plating for termination, housed in black PA6T insulation rated UL94 V-0. The component supports board-to-board or cable connections with a 3A current rating per contact and 250V voltage rating. Operating temperatures range from -40°C to 105°C, with a mating pin length of 5.80mm.

Headers, Male Pins Feature Summary

• Unshrouded vertical surface-mount design for compact board integration
• Dual-plated contacts combining gold mating surfaces with tin terminations
• High-temperature resistant PA6T insulation material ensuring thermal stability

Headers, Male Pins Applications

• Board-to-board interconnections in dense electronic assemblies
• Cable-to-board connections requiring surface-mount termination
• Industrial control modules operating within extended temperature ranges

Headers, Male Pins Procurement Notes

Verify the specific suffix designation against official Harwin documentation to confirm exact plating thickness and packaging configuration. Ensure compatibility with mating socket components regarding height and pin length specifications before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when unshrouded vertical headers are required for space-constrained applications. Confirm that the 2.54mm pitch aligns with existing PCB footprint requirements and that the 3A current capacity meets circuit load demands without derating.

Headers, Male Pins Part Context

This part belongs to the M20 series of rectangular connectors, designed for high-reliability applications. The series offers various position counts and row configurations, all sharing consistent mechanical dimensions and electrical characteristics to simplify supply chain management across different product lines.

Headers, Male Pins Replacement Considerations

Direct substitutes include other M20 series headers with identical 21-position counts and 2.54mm pitch. Verify that alternative sources maintain the same PA6T insulation material and contact plating specifications to ensure functional equivalence.
