M20-7860246

Overview

The M20-7860246 is a 2.54 mm pitch, single-row socket connector from the Harwin M20 series. It features 2 positions with female contacts designed for surface mount technology (SMT) installation. The housing is constructed from UL94 V-0 rated polyamide (PA6T), ensuring high thermal stability and flame resistance. Contacts are made of phosphor bronze with gold plating on the mating interface to guarantee reliable electrical performance. This component supports board-to-board applications within a temperature range of -40°C to +105°C.

Feature Summary

• Surface mount design compatible with standard SMT reflow processes
• Gold-plated phosphor bronze contacts for enhanced conductivity
• UL94 V-0 rated PA6T insulation for thermal resilience

Applications

• Board-to-board interconnections in compact electronic assemblies
• High-density PCB layouts requiring low-profile connectors
• Industrial equipment with strict thermal requirements

Procurement Notes

Verify current lifecycle status as this part may be obsolete or discontinued. Confirm availability through authorized distributors only. Request official datasheets and RoHS compliance documentation before procurement. Check for alternative replacements if supply chain continuity is critical. Validate pin count and orientation against design specifications.

Selection Notes

Select this connector when space constraints necessitate a low-profile SMT solution. Ensure compatibility with 2.54 mm pitch male headers. Verify that the operating environment stays within the specified -40°C to +105°C range. Consider contact plating requirements for corrosion resistance. Confirm mechanical retention needs for surface mount applications.

Part Context

Part of the M20 series, which provides industrial-standard 2.54 mm pitch connectors. Designed for high reliability in demanding environments. Offers various configurations including straight and right-angle options across multiple row counts. Known for robust construction and consistent electrical performance.

Replacement Considerations

Check for direct substitutes within the M20 series such as M20-7860442 for different position counts. Evaluate generic 2.54 mm SMT sockets if specific Harwin features are not required. Ensure replacement matches pitch, row count, and mounting style.
