305-020-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-020-520-558 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features a 20-position configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and accepts between-contact or in-contact polarizing keys. Rated for 5 A continuous current and 1800 VACrms dielectric strength, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, ensuring stability across industrial environments.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 20-position count and 3.96 mm pitch before procurement. Confirm that the application environment remains within the specified -40°C to +105°C operating temperature range. Ensure that the mating card edge thickness aligns with the connector's acceptance specifications. Check for RoHS compliance requirements if applicable to the final assembly standards. Validate that the 5 A current rating suffices for the intended circuit load without derating concerns.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 20-position interface is required with a 3.96 mm pitch. The choice is appropriate for applications needing polarizing key compatibility to prevent misalignment during insertion. Consider this model if gold plating is necessary for corrosion resistance and low contact resistance. Evaluate the panel mount or PCB mount style options available within the 305 series to match the mechanical integration needs of the host system.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and mounting styles. The series is characterized by its standardized 3.96 mm pitch and durable construction suitable for high-reliability applications. Other models in the series share similar electrical ratings and material compositions but differ in pin count and physical dimensions.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are identified in the provided documentation. Cross-referencing requires matching the 20-position count, 3.96 mm pitch, dual-row configuration, and gold-plated contact specifications exactly.
