M20-7820746

Overview

The M20-7820746 is a 7-position female socket connector from the Harwin M20 series, designed for board-to-board applications. It features a 2.54 mm (0.100 inch) pitch and utilizes vertical through-hole termination for secure PCB mounting. The contacts are tin-plated phosphor bronze, ensuring reliable conductivity within a -40°C to +105°C operating temperature range. Constructed with a UL94V-0 rated insulator, this component provides a compact solution for high-density electronic assemblies requiring robust mechanical and electrical performance.

Feature Summary

• Vertical through-hole design facilitates direct printed circuit board integration
• Tin-plated phosphor bronze contacts ensure stable signal transmission
• High-temperature resistant housing material supports standard reflow processes

Applications

• Board-to-board interconnection systems
• Industrial control module interfaces
• Consumer electronics internal wiring

Procurement Notes

Verify the specific pin count and termination style against the official datasheet before procurement. Confirm that the tin plating specification meets the environmental requirements of the target assembly. Ensure the vertical orientation aligns with the mechanical constraints of the host enclosure. Cross-reference the manufacturer part number to avoid confusion with similar SMT or angled variants in the M20 family.

Selection Notes

Select this component when a low-profile, vertical connection is required between two parallel PCBs. The 2.54 mm pitch is suitable for general-purpose digital and power signals. Consider the through-hole mounting method if surface mount space is limited or if higher mechanical retention is needed. Evaluate the current carrying capacity relative to the application load to ensure compliance with thermal limits.

Part Context

This connector belongs to the M20 series, a line of industrial standard headers and sockets known for their compact form factor. The series offers various configurations including single and double rows with different termination options. The M20-7820746 specifically addresses the need for a small footprint vertical socket, fitting within the broader category of rectangular connectors used in dense electronic packaging.
