305-054-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-054-520-201 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 54 positions with a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes copper alloy contacts with gold plating to ensure reliable signal transmission and corrosion resistance. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing mechanical stability and insulation.

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffixes against official EDAC documentation to confirm specific packaging, plating thickness, and environmental compliance details. Ensure that the ordering suffix matches the required insulation resistance and operating temperature specifications. Cross-reference the manufacturer's latest datasheet to confirm availability status and any recent design changes or obsolescence notices before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 54 positions and 3.96 mm pitch is required for vertical panel mounting. Confirm compatibility with 1.57 mm thick PCBs and verify that the 5 A current rating meets the application's electrical demands. Consider the thermoplastic polyester housing material for environmental resilience and ensure the gold-plated contacts align with the necessary conductivity and wear requirements for the intended interface.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and row configurations to accommodate different board densities. The 305-054-520-201 specifically addresses needs for medium-to-high density connections with standardized spacing, fitting into broader system architectures that rely on modular card-based designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-054-520-203 or 305-054-556-278, provided they match the exact position count, pitch, and mounting style. Verify that alternative part numbers maintain identical electrical ratings, thermal limits, and physical dimensions to ensure seamless integration without modifying the existing PCB layout or panel cutouts.
