M22-6540842R

Headers, Receptacles, Female Sockets Overview

The Harwin M22-6540842R is an 8-position surface mount right-angle header from the M22 series. It features a 2.00 mm (0.079 in) pitch and utilizes gold-plated contacts for reliable signal transmission. The connector is designed for horizontal socket assembly on printed circuit boards. It supports a current rating of 2 A and operates within a temperature range defined by its UL 94 V-0 rated housing material.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount right-angle design for efficient PCB integration
• Gold-plated contacts ensure durable connection performance
• High-temperature resistant housing constructed from glass-filled liquid crystal polymer

Headers, Receptacles, Female Sockets Applications

• General purpose electronic assemblies
• Surface mount technology (SMT) manufacturing processes
• Horizontal socket interconnections

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'R' to confirm tape and reel packaging requirements, as this affects handling procedures during automated assembly. Ensure compatibility with standard SMT reflow profiles. Confirm that the 2.00 mm pitch aligns with the target PCB footprint design. Cross-reference the 2 A current rating against actual load conditions to prevent thermal issues.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a horizontal surface mount configuration is required for space-constrained designs. The gold plating offers superior corrosion resistance compared to tin alternatives. The LCP housing provides necessary thermal stability for high-temperature soldering processes. Consider the 8-way count for specific channel requirements.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Harwin M22 series, which offers various configurations including single-row latching and double-row jackscrew options. The series is characterized by compact silhouettes suitable for dense board layouts. The M22-6540842R specifically addresses the need for robust, high-reliability surface mount interconnects in modern electronics.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same series include other 8-position variants such as M22-6540842 without the reel suffix if loose parts are acceptable. Verify pin count, pitch, and mounting orientation before substitution.
