306-031-520-103

Overview

The EDAC Inc. 306-031-520-103 is a standard card edge connector from the 306 series, designed for panel mounting applications. It features a dual female configuration with 62 positions and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts housed in a green thermoplastic shell. It supports a current rating of 5 A and offers an insulation resistance of 5 GOhms. The unit is constructed to accommodate specific board thicknesses and provides vertical installation orientation for reliable signal transmission.

Feature Summary

• Dual female contact configuration for secure card edge mating
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Thermoplastic housing material provides structural integrity and insulation
• Panel mount design facilitates stable vertical integration

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment interface modules
• Test and measurement instrumentation backplanes
• Automotive electronic control unit connections

Procurement Notes

Verify the exact part number against official EDAC documentation to confirm pin count and plating specifications. Ensure compatibility with target PCB stack-up dimensions before procurement. Cross-reference manufacturer datasheets for environmental ratings and mechanical tolerances to prevent integration errors during assembly and testing phases.

Selection Notes

Select this component when a high-density dual-sided connection is required with a 3.96 mm pitch. Consider the 5 A current capacity and gold plating for durability in demanding environments. Verify that the panel mount style aligns with the enclosure design constraints and that the vertical orientation fits within the available spatial envelope without interference.

Part Context

This connector belongs to the EDAC 306 series, which specializes in standard card edge solutions. The series is characterized by its use of thermoplastic materials and gold-plated contacts. The 306-031-520-103 variant specifically addresses applications needing 62 positions with a 0.156-inch spacing, offering a balance between density and mechanical stability for industrial-grade deployments.

Replacement Considerations

Direct substitutes include other EDAC 306 series connectors with matching position counts and pitch. Verify equivalent electrical ratings and mounting styles when evaluating alternative part numbers from the same manufacturer family to maintain system consistency.
