305-072-556-504

Edgeboard Connectors Overview

The EDAC Inc. part number 305-072-556-504 is a standard card edge connector from the 305 series, designed for dual-edge PCB insertion. It features 72 positions with a 3.96 mm (0.156 inch) pitch and supports a board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts rated for 5 A current. Constructed with a thermoplastic polyester housing in green, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure connection to double-sided card edge PCBs
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester housing provides structural integrity and thermal stability
• Panel mount configuration allows for robust vertical installation on chassis or enclosures

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing modular card architectures
• Test and measurement instruments needing durable panel-mounted interfaces
• Automotive electronics assemblies demanding stable electrical connections

Edgeboard Connectors Procurement Notes

Verify the complete part number against official EDAC documentation to confirm specific suffix variations such as termination type or plating thickness. Ensure compatibility with target PCB dimensions, specifically the 1.57 mm thickness requirement. Confirm that the 72-position layout matches the design footprint. Cross-reference RoHS compliance status if environmental regulations apply to the final assembly. Validate supplier authenticity through authorized distribution channels.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is required for 72 signals with a 3.96 mm pitch. It is suitable for applications necessitating panel mounting rather than direct PCB surface mounting. Consider the 5 A current rating and operating temperature range for environmental suitability. Compare against single-edge variants if only one side of the PCB is utilized. Evaluate housing material properties for chemical resistance needs in industrial environments.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series offers various position counts and mounting styles to accommodate diverse electronic module designs. The 305-072 variant specifically addresses medium-to-high density requirements. It complements other EDAC products by providing standardized mechanical and electrical interfaces for modular system integration across multiple industries.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include EDAC part numbers with identical 72-position specifications but different suffixes indicating alternate termination methods or packaging. Verify mechanical dimensions and pinout configurations before substitution. Generic equivalents from other manufacturers require rigorous testing to ensure pitch and contact alignment compatibility.
