M20-7830946

Overview

The M20-7830946 is a vertical receptacle connector from the Harwin M20 series, designed for through-hole mounting on printed circuit boards. It features a single row with 9 positions and a standard 2.54mm (0.1 inch) contact pitch. The connector utilizes female contacts made of phosphor bronze with nickel and tin plating to ensure reliable signal transmission. 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 UL94 V-0 rated high-temperature liquid crystal polymer (LCP), providing robust mechanical stability and flame resistance suitable for industrial environments.

Feature Summary

• Vertical through-hole design optimized for board-to-board applications
• High-temperature LCP insulation material ensuring UL94 V-0 flame rating
• Dual-beam contact structure for enhanced electrical reliability
• Standard 2.54mm pitch compatible with industry-standard mating headers

Applications

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

Procurement Notes

Verify the specific part number M20-7830946 against official Harwin documentation to confirm availability and lead times. Ensure that the required stacking heights align with system constraints before procurement. Check for RoHS compliance status in the latest datasheet. Confirm that the 3A current rating meets the application's electrical requirements. Validate that the through-hole mounting style matches the PCB fabrication capabilities.

Selection Notes

Select this component when a vertical, single-row female header is required for 2.54mm pitch connections. Consider the 1000V voltage rating and 3A current capacity for circuit design. The LCP housing makes it suitable for high-temperature processing environments. Compare stacking height options if multiple mating configurations are needed. Ensure the through-hole installation method fits the assembly process.

Part Context

This component belongs to the Harwin M20 series, which offers a range of 2.54mm pitch connectors. The series includes various row counts, pin configurations, and mounting styles such as surface mount and through-hole. The M20-7830946 specifically represents a 9-position vertical receptacle variant within this comprehensive interconnect family.

Replacement Considerations

Check for direct substitutes within the M20 series with different pin counts or row configurations. Verify compatibility with mating male headers of the same 2.54mm pitch. Ensure any replacement maintains the same voltage, current, and temperature ratings.
