M20-7871246P

Overview

The Harwin M20-7871246P is a 26-position dual in-line socket assembly from the M20 series, designed for board-to-board or cable connections. It features a 2.54 mm pitch and utilizes surface mount termination with bottom entry and selective gold plus tin plating. The component operates within a temperature range of -55°C to +105°C and carries RoHS compliance certification.

Feature Summary

• Dual beam contact design provides improved electrical connection and enhanced reliability
• UL94V-0 high temperature liquid crystal polymer housing withstands SMT reflow processes
• Bottom entry configuration facilitates compact PCB density and height constraint designs

Applications

• Embedded PC systems
• Motherboard interconnects
• Large electronic system integration

Procurement Notes

Verify the specific suffix 'P' against official Harwin documentation to confirm it denotes the required bottom entry orientation and selective plating finish. Ensure the selected variant matches the intended surface mount assembly process and spatial constraints on the target printed circuit board layout.

Selection Notes

Select this component when a robust, high-density DIL socket is required for SMT assembly. The bottom entry style is optimal for applications where vertical space is limited. Confirm that the 2.54 mm pitch aligns with mating header specifications and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the M20 series, which serves as an industry standard for PCB through-hole and surface mount industrial sockets. The series is widely adopted in embedded computing and communication equipment due to its durability and compatibility with standard manufacturing processes.

Replacement Considerations

M20-7871342 is a confirmed substitute offering identical 26-position DIL configuration with gold plus tin plating, though it utilizes nickel-tin contacts instead of selective gold.
