306-033-420-103

Overview

The EDAC Inc. part number 306-033-420-103 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 66 positions arranged in two rows, providing a total contact count of 66. The connector utilizes a 3.96 mm pitch and accommodates a board thickness of 3.96 mm (0.156 inches). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 Gohms. The contacts are gold-plated copper alloy, housed in a thermoplastic polyester shell, ensuring reliable signal transmission in industrial environments.

Feature Summary

• Dual female card edge design for secure PCB insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing for thermal stability
• Panel mount vertical installation style

Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation panels
• Automotive electronic module connections

Procurement Notes

Verify the specific suffix code to confirm contact plating and housing material variations. Ensure compatibility with the target PCB thickness of 0.156 inches before procurement. Check manufacturer lead times as this item may be subject to non-stocked availability. Confirm that the 66-position layout matches the circuit board footprint requirements. Validate insulation resistance ratings against environmental operating conditions.

Selection Notes

Select this component when a high-density 66-position interface is required for panel-mounted assemblies. The dual-row configuration maximizes connection density within a standard form factor. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify that the vertical mounting orientation aligns with the chassis design constraints. Ensure the thermoplastic housing meets the temperature range requirements of the application environment.

Part Context

This connector belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its reliability in harsh environments and standardized dimensions. The 306 series offers various position counts and row configurations to suit different connectivity needs. This specific model represents a high-pin-count solution within the standard density category.

Replacement Considerations

Direct substitutes must match the 66-position dual female configuration and 3.96 mm pitch. Verify that alternative parts support the same 0.156 inch board thickness. Ensure equivalent current ratings and insulation resistance values. Cross-reference mounting hole patterns for panel compatibility.
