M20-8770546R

Headers, Male Pins Overview

The Harwin M20-8770546R is a surface mount header connector from the M20 series, designed for board-to-board or cable connections. It features a single row with five positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes square male pin contacts with tin plating on both mating and tail surfaces. Constructed with brass contacts and black polyamide (PA6T) insulation rated UL94 V-0, it supports a maximum current of 3A per contact. The operating temperature range spans from -40°C to 105°C.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official datasheet to confirm reel packaging specifications and orientation requirements. Ensure compatibility with standard SMT reflow profiles and check for any RoHS compliance documentation updates prior to final procurement approval.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row surface mount header is required for 2.54mm pitch applications. Consider the 3A current rating and -40°C to 105°C temperature range for environmental suitability. Verify that the PCB footprint matches the specific SMT pad layout defined in the M20 series mechanical drawings.

Headers, Male Pins Part Context

This part belongs to the Harwin M20 series, a widely used rectangular connector family known for its versatility in high-density applications. The M20 series offers various configurations including through-hole and surface mount options, catering to diverse industrial and consumer electronics needs while maintaining consistent 2.54mm spacing standards.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M20-8770546 (tray packaged). Cross-brand replacements must match the 5-position count, 2.54mm pitch, surface mount termination, and tin-plated contact finish to ensure mechanical and electrical compatibility.
