M20-7821042

Overview

The Harwin M20-7821042 is a 10-position single-row female socket connector from the M20 series, designed for board-to-board applications. It features a 2.54 mm pitch and vertical through-hole mounting orientation. The contacts are made of bronze with gold and tin plating to ensure reliable electrical performance. Rated for 12A current and 1000V voltage, it operates within a temperature range of -55°C to 105°C. The housing utilizes high-temperature nylon or polyamide (PA6T/Nylon 6T) insulation.

Feature Summary

• Vertical single-row configuration for compact PCB integration
• Dual-beam contact design for enhanced connection reliability
• High-temperature resistant housing material suitable for reflow processes

Applications

• Industrial equipment interconnections
• Telecommunications hardware assembly
• General purpose electronic circuit boards

Procurement Notes

Verify the specific contact plating specification against the official datasheet, as listings may vary between nickel-tin and gold-tin variants for this part number. Confirm RoHS compliance status directly with the manufacturer documentation prior to procurement to ensure regulatory adherence for your specific application requirements.

Selection Notes

Select this component when a vertical, unshrouded single-row interface is required for board-to-board connections. Ensure the design accommodates the 2.54 mm pitch and through-hole mounting constraints. Verify that the 1000V rating and 12A current capacity meet the system's electrical demands and environmental temperature specifications.

Part Context

This connector belongs to the Harwin M20 series, which provides industrial standard sockets with 2.54 mm spacing. The series offers various configurations including single and double rows, supporting both surface mount and through-hole technologies. These connectors are engineered to meet strict density and height limitations in modern PCB designs while maintaining robust mechanical and electrical properties.

Replacement Considerations

M20-7821046 is a similar 10-position single-row socket but features nickel-tin plating instead of gold-tin. Verify that the plating difference does not impact the application's corrosion resistance or conductivity requirements before substituting.
