M20-7820642

Overview

The M20-7820642 is a 6-position female receptacle connector from the Harwin M20 series. It features a 2.54mm (0.1 inch) pitch with a single row configuration. The unit utilizes through-board termination with 3mm PCB tails and square contact shapes. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from black polyamide (PA6T) nylon with UL94 V-0 flammability rating. Gold-plated contacts ensure reliable signal transmission.

Feature Summary

• Single-row vertical design facilitates board-to-board or cable stacking applications
• Push-pull locking mechanism ensures secure mechanical connection
• Gold-plated phosphor bronze contacts provide durable electrical performance
• UL94 V-0 rated polyamide insulation supports high-temperature industrial environments

Applications

• General purpose electronic interconnections
• Industrial control system wiring
• Telecommunications equipment assembly

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm that the part number matches exactly, as suffixes may indicate variations in plating or packaging. Ensure compliance with RoHS directives if required for your specific application environment. Cross-reference terminal counts and pitch dimensions to prevent integration errors during procurement.

Selection Notes

Select this component when a low-profile, single-row female connector is required for vertical mating. The 2.54mm pitch is standard for general electronics, while the 3mm tail length accommodates specific board thicknesses. Consider the 1000V rating for higher voltage isolation needs compared to standard 500V connectors. Verify that the push-pull retention style aligns with the mating header's release mechanism requirements.

Part Context

This receptacle belongs to the M20 series, known for robust rectangular connectors. The M20-7820642 specifically addresses the need for compact, high-reliability connections in dense circuit layouts. Its design prioritizes mechanical stability and electrical consistency across various environmental conditions, making it suitable for demanding sectors like telecommunications and industrial automation.

Replacement Considerations

Direct substitutes within the same series include M20-7820646, which offers identical electrical characteristics but with different pin configurations. When replacing, verify that the mating header uses compatible push-pull latches and matches the 2.54mm pitch specification to ensure proper physical engagement.
