M20-7873346

Overview

The Harwin M20-7873346 is a 3-position, single-row PCB socket connector from the M20 series. It features a 2.54 mm pitch and utilizes nickel-plated tin contacts made of phosphor bronze for reliable electrical performance. Designed for board-to-board applications, this component employs through-hole solder termination and straight orientation. The housing is constructed from high-temperature nylon to withstand standard SMT reflow processes. It operates within a temperature range of -55°C to 105°C and complies with RoHS standards.

Feature Summary

• Dual-beam contact design ensures improved electrical connection and enhanced reliability
• Housing material compatible with surface mount technology reflow profiles
• Compact form factor supports high-density PCB layout requirements

Applications

• Embedded PC systems
• Motherboard interconnections
• Industrial monitoring equipment
• Communication devices

Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability status. Some listings indicate end-of-life or obsolescence for similar M20 series variants. Ensure compliance with current environmental regulations and check for updated manufacturing data before procurement.

Selection Notes

Select this component when a low-profile, single-row female header is required for rigid board-to-board connections. The 2.54 mm pitch aligns with standard industrial interfaces. Consider the through-hole mounting method and operating temperature limits relative to the target application environment.

Part Context

This connector belongs to the Harwin M20 series, which provides industrial-standard PCB headers and sockets. The series offers various row configurations and pin counts, serving as a common interface solution for embedded computing and large electronic systems requiring robust mechanical and electrical stability.

Replacement Considerations

Check for direct substitutes within the M20 series such as M20-7871342 for different pin counts. Verify that any replacement maintains the same 2.54 mm pitch, through-hole termination, and housing material specifications to ensure mechanical compatibility.
