M20-7870546

Overview

The Harwin M20-7870546 is a surface-mount socket connector from the Indess series, featuring a 10-position (5+5) dual-in-line configuration with a 2.54mm pitch. It utilizes gold and tin plating on phosphor bronze contacts for reliable signal transmission. The housing is constructed from high-temperature liquid crystal polymer rated UL94 V-0, ensuring stability during reflow soldering processes. Designed for board-to-board applications, this component supports a current rating of 3A per contact and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Surface-mount design compatible with standard SMT reflow processes
• Dual-insulated design with bottom entry for compact PCB layouts
• High-temperature LCP housing material ensures thermal stability

Applications

• Board-to-board interconnections in industrial equipment
• Telecommunications hardware requiring high-density connections
• General-purpose electronic systems needing reliable SMT headers

Procurement Notes

Verify that the specific ordering suffix corresponds to the gold plus tin plating option, as variations exist within the M20-787 family. Confirm the surface-mount package type matches the target PCB footprint requirements. Ensure compatibility with automated assembly lines by checking reel packaging specifications if applicable. Cross-reference the UL94 V-0 rating against project safety standards.

Selection Notes

Select this model when a low-profile, surface-mount female header is required for high-density board stacking. The dual-row layout optimizes space efficiency compared to single-row alternatives. Consider the operating temperature range and current capacity for load requirements. Verify that the bottom-entry design aligns with mechanical clearance constraints on the assembly.

Part Context

This component belongs to the Harwin M20 Indess series, which specializes in compact, high-reliability connectors for demanding environments. The series offers various configurations including through-hole and surface-mount options. The M20-787 variant specifically addresses needs for small-footprint, double-insulated sockets that withstand harsh thermal conditions during manufacturing.

Replacement Considerations

Compatible substitutes include other M20 series surface-mount sockets with identical pin counts and pitch. Verify equivalent plating specifications and insulation materials before substitution. Ensure mechanical dimensions match the existing PCB land pattern to maintain assembly integrity.
