M22-6540442R

Headers, Receptacles, Female Sockets Overview

The Harwin M22-6540442R is a 4-position single in-line (SIL) surface mount header from the M22 series. It features a 2.00 mm pitch and is designed for right-angle board-to-board connections. The connector utilizes phosphor bronze contacts with selective gold plating over tin, ensuring reliable signal transmission. Rated for 1 A current and 650 VAC voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black nylon compliant with UL 94 V-0 flammability standards. This component is supplied in tape and reel packaging for automated assembly.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount design enables efficient automated pick-and-place manufacturing processes.
• Selective gold plating on contact areas provides enhanced corrosion resistance and low contact impedance.
• Right-angle configuration facilitates compact vertical interconnects between PCB layers.

Headers, Receptacles, Female Sockets Applications

• Compact consumer electronics requiring space-saving vertical connections
• Industrial control modules with limited board real estate
• Automotive infotainment systems needing robust surface mount interfaces

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'R' confirms tape and reel packaging requirements for your SMT line. Ensure compatibility with standard reflow soldering profiles compatible with lead-free processes. Confirm that the right-angle orientation aligns with your mechanical enclosure constraints. Cross-reference the 4-position count against your schematic to prevent pinout mismatches during assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this part when a low-profile, right-angle surface mount connection is required for small signal applications. The 2.00 mm pitch offers a balance between density and manufacturability. Choose this model over through-hole variants if board space is constrained or if automated assembly efficiency is prioritized. Verify that the 1 A current rating meets the thermal requirements of your specific circuit design.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Harwin M22 series, a family of high-density connectors known for their reliability in harsh environments. The M22 series supports various configurations including headers, sockets, and shrouded options. The M22-6540442R specifically addresses the need for horizontal surface mount interconnects with precise alignment features typical of the broader M22 product line.

Headers, Receptacles, Female Sockets Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 2.00 mm pitch, 4-position count, right-angle orientation, and surface mount termination style. Verify mechanical footprint compatibility before considering alternative manufacturers.
