305-082-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-503 is a standard card edge connector from the 305 series, designed for dual female board-to-board or backplane applications. It features 82 positions with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic insulator. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit is panel-mounted vertically with solder pin termination.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure card edge engagement
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic insulation provides structural stability and electrical isolation

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific plating thickness and flange configurations. Confirm that the target application requires a dual female interface rather than single row or male variants. Check RoHS compliance status against specific regional regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical connection is required. Ensure the mating card thickness falls within the specified tolerance for the 305 series. Verify that the panel mounting style aligns with the mechanical enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various position counts and termination styles. It is distinct from the 315 and 355 series by its specific dimensional profile and contact arrangement. The 305 series is widely used in rugged environments requiring durable connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching pin counts and pitch, such as 305-072-521-503 or 305-094-521-503, provided mechanical fit and electrical ratings are identical.
