305-084-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-201 is a dual-edge female card edge connector designed for through-hole PCB mounting. It features 84 positions with a 0.156-inch (3.96 mm) contact spacing and accepts non-specified dual-edge cards. The contacts are gold-plated copper alloy with a 10.0 µin thickness, utilizing a semi-crimped termination style. Rated for 5A continuous current and 1800VACrms insulation, it operates within a -40°C to 105°C range. The housing is green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Semi-crimped contact design ensures reliable electrical connection
• Gold-plated terminals provide corrosion resistance and low contact resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• High-density circuit board assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct pin count, termination type, and flange configuration. Confirm that the target application supports the required 5A current rating and 1800VACrms voltage isolation. Cross-reference the mechanical dimensions with the product drawing to validate panel cutout requirements and mating card thickness specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is required for rigid PCB applications. The 0.156-inch pitch accommodates standard board layouts while providing ample spacing for high-voltage isolation. Ensure the mating card thickness falls within the specified tolerance range to maintain proper contact engagement and mechanical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various pin counts and configurations optimized for through-hole assembly. The 305-084 variant specifically addresses applications needing 84 signal paths with standardized mechanical interfaces compatible with industry-standard dual-edge modules.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 84-position dual-edge specifications. Verify compatibility by matching the 0.156-inch pitch, gold plating thickness, and through-hole termination style. Consult the official cross-reference guide for equivalent parts from other manufacturers if supply constraints exist.
