M20-7870446R

Overview

The Harwin M20-7870446R is an 8-position rectangular receptacle connector from the M20 series. It features a 2.54 mm (0.1 in) pitch and utilizes surface mount termination for PCB integration. The assembly includes two rows of female sockets with bottom or top entry capabilities. Contacts are tin-plated, and the housing is constructed from black nylon. The component supports board-to-board and cable applications within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-row socket configuration providing compact connectivity solutions
• Surface mount design facilitates automated PCB assembly processes
• Flexible contact entry options allow for versatile mating orientations

Applications

• Board-to-board interconnections
• Cable-to-board wiring harnesses
• General electronic equipment signal routing

Procurement Notes

Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging requirements. Ensure compatibility with standard reflow soldering profiles for tin-plated contacts. Confirm that the selected variant matches the required entry direction for the target assembly design.

Selection Notes

Select this component when a low-profile, dual-row surface mount solution is required. The 2.54 mm pitch ensures compatibility with standard pin headers. Consider the tin plating for cost-effective general-purpose applications where gold plating is not strictly necessary for corrosion resistance.

Part Context

This part belongs to the Harwin M20 series, which specializes in 2.54 mm pitch connectors. The series offers various configurations including through-hole and surface mount options. The M20-787 series specifically denotes dual-row receptacles designed for high-density mounting on printed circuit boards.

Replacement Considerations

Direct substitutes include other Harwin M20 series dual-row SMT receptacles with identical 8-position counts and 2.54 mm pitch. Verify mechanical dimensions and terminal plating before substitution.
