305-082-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-082-521-558 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 82 positions in a dual female configuration, utilizing a 0.156-inch (3.96 mm) contact spacing and a 0.140-inch (3.56 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The unit provides a continuous current rating of 5 A and supports a voltage rating of 1800 VACrms.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified card edge applications
• Gold-plated copper alloy contacts for corrosion resistance and conductivity
• Accepts between-contact and in-contact polarizing keys for secure mating
• Low profile insulator body constructed from thermoplastic material

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment board connections
• Automotive electronics modules
• Medical device internal circuitry
• Aerospace and defense avionics subsystems

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, contact finish, and flange characteristics. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status and lead time requirements directly with authorized distributors, as availability may vary by region. Cross-reference the part number with the latest datasheet to validate electrical ratings before integration.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-row interface is required for vertical panel mounting. The 0.156-inch pitch offers a balance between density and ease of assembly. Consider the 5 A current rating for power distribution needs within the module. Verify that the housing material meets the thermal requirements of the operating environment, which ranges from -40°C to +105°C. Ensure the design accommodates the specified polarizing key options if mechanical locking is necessary.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, a line of standard card edge connectors known for robust performance in demanding environments. The series typically includes various position counts and configurations to support diverse electronic packaging needs. These components are widely used in industries requiring reliable, high-speed data and power transfer between backplanes and daughter cards.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with differing pin counts or contact finishes. No specific public substitute part numbers are confirmed for this exact configuration. Ensure any replacement maintains the 0.156-inch pitch and dual female interface specifications.
