305-082-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-501 is a dual-edge female card edge connector from the 305 Series, designed for through-hole mounting. It features 82 positions with a 0.156-inch (3.96mm) contact spacing and gold-plated contacts. The connector accepts non-specified dual-edge cards with thicknesses between 0.054 and 0.070 inches. It offers a 5A continuous current rating and 1800VACrms dielectric strength, operating within -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Provides high dielectric strength of 1800VACrms for reliable insulation
• Features gold-plated half-wave spring contacts for durable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing reliable signal pathways
• Automotive technology applications in harsh environments

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact plating and housing color specifications. Confirm that the target PCB design accommodates the required through-hole footprint and panel thickness constraints. Check RoHS3 compliance status if environmental regulations apply to the specific manufacturing region or end-use application requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required with substantial current carrying capacity. The 0.156-inch pitch allows for broader trace routing compared to finer pitches. Ensure the mating card thickness falls within the specified 0.054 to 0.070-inch range for proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which provides standardized edgeboard solutions. The series supports various pin counts and contact spacings, allowing designers to scale connectivity density while maintaining consistent mechanical interfaces. The 305-082 variant specifically addresses high-pin-count applications requiring dual-sided board insertion.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 0.156-inch pitch and dual-edge configuration. Verify mechanical dimensions and electrical ratings against alternative suppliers' offerings to ensure functional equivalence without modifying the existing PCB layout or assembly processes.
