M20-7822042

Overview

The Harwin M20-7822042 is a 20-position vertical socket assembly from the M20 series, designed for board-to-board applications. It features a 2.54mm pitch and utilizes through-hole termination. The connector employs gold-plated contacts housed in a high-temperature liquid crystal polymer (LCP) shell rated UL94V-0. This design supports standard reflow soldering processes while maintaining compact dimensions to meet PCB density constraints.

Feature Summary

• Vertical orientation with through-hole mounting for reliable PCB integration
• Gold-plated contacts ensure stable electrical connections
• High-temperature LCP housing withstands reflow soldering profiles

Applications

• Board-to-board interconnect systems
• High-density PCB layouts requiring vertical sockets
• Industrial electronic assemblies

Procurement Notes

Verify the specific ordering suffix against official Harwin documentation to confirm pin count, plating, and orientation. Ensure compatibility with mating header specifications before procurement. Cross-reference datasheet revisions to confirm current manufacturing status and environmental compliance certifications.

Selection Notes

Select this component when vertical space is limited but through-hole reliability is required. The 2.54mm pitch suits standard industrial interfaces. Verify that the mating header matches the 20-position requirement and compatible contact geometry for proper engagement.

Part Context

Part of the M20 family, known for compact industrial connectors. Designed to balance height restrictions with robust mechanical performance. Suitable for environments demanding durability during assembly and operation.

Replacement Considerations

No public confirmed substitute part numbers are available. Consult Harwin directly for equivalent alternatives within the M20 series or other compatible connector families.
