M20-7870342

Overview

The Harwin M20-7870342 is a dual-in-line socket assembly from the M20 series, designed for surface-mount technology. It features a 2.54 mm (0.1 in) pitch with 6 positions arranged in a 3+3 configuration across two rows. The connector utilizes gold and tin-plated contacts housed in a polyamide (PA6T) or Nylon 6T insulation material rated UL94V-0. Rated for 1000V and square contact shapes, it supports bottom entry termination. Operating temperatures range from -40°C to 105°C, ensuring reliability in industrial and telecommunications environments.

Feature Summary

• Dual-in-line surface-mount architecture optimized for high-density PCB layouts
• Square contact geometry with mixed gold and tin plating for enhanced conductivity
• High-temperature resistant polyamide insulation compatible with standard SMT reflow processes

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing high-voltage signal transmission
• General-purpose electronic assemblies needing reliable surface-mount interfaces

Procurement Notes

Verify component authenticity through authorized Harwin distributors or certified partners. Confirm RoHS compliance status via official documentation before integration. Ensure storage conditions maintain integrity of the tin-gold plated contacts against oxidation. Validate that the selected variant matches the specific 3+3 pin configuration required for the target circuit design.

Selection Notes

Select this model when a low-profile, surface-mount solution is required for dual-row interconnections. The 2.54 mm pitch ensures compatibility with standard industry footprints. Consider the mixed plating option if cost efficiency is prioritized alongside moderate corrosion resistance. Verify mechanical height constraints as the assembly adds specific profile dimensions to the PCB stack-up.

Part Context

Part of the widely adopted M20 series, known for its compact form factor and durability. This series serves as a standard interface for embedded PCs and large-scale electronic systems. The M20-7870342 specifically addresses the need for reliable SMT termination in space-constrained applications without sacrificing electrical performance.

Replacement Considerations

Direct substitutes within the M20 series include variants with different pin counts or plating options, such as M20-7870346. Cross-series replacements require careful verification of pitch, row configuration, and mounting style to ensure mechanical and electrical compatibility.
