305-074-555-578

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-578 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 74 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses of 1.57 mm. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. Constructed with a thermoplastic polyester housing in green, it operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure engagement with double-sided card edges
• Gold plating on copper alloy contacts ensures reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural stability and electrical insulation properties

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing high-density vertical connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact housing material and termination style variations. Ensure compatibility with target PCB thickness tolerances before procurement. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve over time.

Edgeboard Connectors Selection Notes

Select this component when a 74-position interface with 3.96 mm spacing is required for vertical panel mounting. Consider the 5 A current rating and operating temperature limits for environmental suitability. Verify that the dual-edge card design aligns with the system's mechanical constraints and signal integrity requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting options, providing flexibility for different board densities and enclosure designs while maintaining consistent electrical performance standards across the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes indicating variant materials or terminations. Cross-series replacements require careful evaluation of mechanical dimensions and electrical ratings to ensure functional equivalence without redesigning the host assembly.
