M20-7833742

Overview

The M20-7833742 is a rectangular socket connector from the Harwin M20 series, designed for board-to-board or cable stacking applications. It features 74 positions arranged in two rows with a 0.100-inch (2.54mm) pitch. The connector utilizes phosphor bronze contacts with gold plating and a polyamide (PA6T) insulation material rated UL94 V-0. Rated for 3A current and 1000V voltage, it operates within a temperature range of -40°C to 105°C. The assembly employs a push-pull fastening mechanism and offers stack heights of 11.04mm or 12.63mm.

Feature Summary

• Push-pull locking mechanism ensures secure mating and unmating
• Gold-plated phosphor bronze contacts provide reliable electrical performance
• High-temperature resistant PA6T insulation housing meets UL94 V-0 standards
• Compact dual-row design supports high-density PCB layouts

Applications

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

Procurement Notes

Verify component status prior to procurement as this part number is marked as obsolete by the manufacturer. Confirm availability through authorized distributors or secondary market channels. Ensure that any replacement strategy accounts for potential supply chain constraints associated with end-of-life components. Validate mechanical fit and electrical specifications against current design requirements before finalizing orders.

Selection Notes

Select this connector when high-voltage isolation up to 1000V is required in a compact form factor. The dual-row configuration maximizes pin density while maintaining standard 2.54mm spacing. Consider the specific stack height options available to ensure compatibility with enclosure constraints. The push-pull feature is advantageous for applications requiring frequent maintenance or robust mechanical retention.

Part Context
