M20-7820942

Overview

The M20-7820942 is a single-row, vertical receptacle from the Harwin M20 series. It features 9 female contacts with a 2.54 mm (0.1 inch) pitch. Designed for through-hole mounting, it utilizes gold and tin plating on phosphor bronze contacts. The housing is constructed from polyamide (PA6T) rated UL94 V-0, providing electrical insulation. Rated for 3 A current and 1000 V voltage, it operates within a temperature range of -40°C to +105°C. The connector height is 8.5 mm, suitable for board-to-board or cable stacking applications.

Feature Summary

• Vertical single-row design for compact board-to-board interconnects
• Gold and tin contact plating for reliable signal transmission
• UL94 V-0 rated polyamide insulation for thermal stability

Applications

• General purpose electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm that the part number suffix matches the specific plating and orientation requirements. Ensure storage conditions comply with moisture sensitivity levels if applicable. Validate that the supplier provides traceability documentation for quality assurance purposes before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, single-row vertical interface is required. The 2.54 mm pitch ensures compatibility with standard PCB layouts. Consider the 8.5 mm height constraint for enclosure clearance. Verify that the 3 A current rating meets the circuit load requirements. Ensure the through-hole termination method aligns with the manufacturing process capabilities.

Part Context

This part belongs to the M20 series, known for high-density interconnect solutions. The M20-7820942 specifically addresses needs for reliable vertical connections in space-constrained environments. Its design supports automated assembly processes due to the standardized pin spacing and robust mechanical locking features inherent to the series.

Replacement Considerations

M20-7820942 is a discontinued product. Potential substitutes include M20-7820946 or other M20 series variants with compatible pin counts and orientations. Verify mechanical dimensions and electrical ratings before substitution.
