305-074-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-578 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features 74 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator body, it provides a continuous current rating of 5 A and withstands 1800 VACrms. The unit utilizes solder pin termination for secure PCB attachment.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Low profile insulator body design for space-constrained installations
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical panel mount configuration with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Test and measurement instrumentation needing high-density connections
• Automotive electronics modules with specific polarizing requirements

Edgeboard Connectors Procurement Notes

Verify the exact position count and series designation against official EDAC documentation before procurement. Confirm that the target application supports the specified 1.57 mm board thickness and vertical mounting orientation. Ensure compatibility with required polarizing key configurations if mechanical locking is necessary for the assembly. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Edgeboard Connectors Selection Notes

Select this component when a high-position-count connector is required for vertical panel integration. The 3.96 mm pitch allows for moderate density while maintaining reliable electrical performance. Consider the 5 A current rating and voltage withstand capabilities for power distribution needs. Verify that the thermoplastic housing material meets environmental temperature requirements for the intended operating range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic designs. The series offers various position counts and mounting styles to accommodate different board sizes and system architectures. The 305-074 variant specifically addresses applications requiring a higher density of interconnections within a single connector footprint.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternative part numbers. Ensure any substitute maintains the same 3.96 mm pitch, 74 position count, and vertical mounting style. Verify that replacement components support the same board thickness and polarizing key acceptance capabilities.
