306-027-421-103

Overview

The EDAC Inc. 306-027-421-103 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 54 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes copper alloy contacts with tin plating and a green thermoplastic polyester housing. Rated for 5 A current, it supports vertical panel mount installation via solder pin termination. Operating temperatures range from -40°C to 105°C, ensuring reliability in industrial environments.

Feature Summary

• Dual-edge female contact configuration for secure board retention
• Vertical panel mount design with flanged mounting options
• Thermoplastic polyester insulation for high-temperature stability
• Copper alloy contacts with tin plating for reliable signal transmission

Applications

• Industrial control system backplanes
• Medical device interconnects

Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified supply chain partners. Confirm RoHS compliance status and specific lot traceability requirements prior to order placement. Ensure storage conditions maintain moisture sensitivity level integrity. Validate that the received part number matches the exact suffix specifications for contact plating and housing color variants.

Selection Notes

Select this model when dual-edge connectivity with a 3.96 mm pitch is required for vertical panel integration. Consider the 5 A current rating and -40°C to 105°C operating range for environmental suitability. Evaluate the tin-plated contacts against gold-plated alternatives if higher corrosion resistance is needed for specific operational lifecycles.
