305-014-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-014-520-278 is a dual-edge female card edge connector from the 305 Series, designed for panel mount and through-hole termination. It features 14 positions with a 0.156-inch (3.96mm) contact spacing and 0.140-inch row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contacts are gold-plated copper alloy with a 10.0µin thickness, rated for 5A continuous current and 1800VACrms insulation. The insulator is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact assembly requirements
• Gold-plated contacts ensure reliable electrical performance and corrosion resistance
• Dual-edge configuration supports non-specified board types with robust mechanical retention

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Telecommunications equipment utilizing standard card edge modules
• Test and measurement instrumentation with modular board architectures
• Automotive electronics assemblies needing durable panel-mounted connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required polarizing key compatibility and board thickness tolerance. Confirm RoHS3 compliance status for environmental regulations. Ensure the ordering quantity aligns with the manufacturer's standard packaging units to avoid partial reel issues. Cross-reference the datasheet revision date to guarantee compatibility with current design specifications.

Edgeboard Connectors Selection Notes

Select this model when a 14-position dual-edge interface is required with a 3.96mm pitch. The 5A current rating suits moderate power distribution needs. Verify that the target PCB thickness falls within the acceptable range for proper contact engagement. Consider the low-profile body if vertical space constraints exist within the enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles while maintaining consistent electrical characteristics. The 305-014 variant specifically addresses applications needing fewer pins than higher-count models like the 305-054 or 305-048, providing a balanced solution for smaller form-factor designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-014-520-258 and 305-014-521-202, provided they match the exact pin count and termination style. Verify that any replacement maintains the same 0.156-inch pitch and gold plating specification to ensure electrical continuity.
