306-033-521-104

Overview

The EDAC Inc. 306-033-521-104 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual female configuration with 66 total positions arranged in two rows of 33, utilizing a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, rated for 5 A current, and housed in a thermoplastic body. It supports a board thickness of 1.57 mm and offers an insulation resistance of 5 GOhms.

Feature Summary

• Dual-edge female contact design for secure card insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural stability
• Vertical panel mount style facilitates direct integration

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics module connections
• Medical device circuit board interfaces

Procurement Notes

Verify the specific suffix code to confirm the exact pin count and plating specifications, as variations exist within the 306 series. Ensure compatibility with the target PCB thickness of 1.57 mm before finalizing orders. Confirm that the vertical mounting style aligns with the mechanical enclosure requirements. Cross-reference the manufacturer's latest documentation to validate current availability status.

Selection Notes

Select this component when a dual-row connection is required for high-density signal routing. The 3.96 mm pitch accommodates standard card edge widths while maintaining robust contact retention. The vertical orientation simplifies assembly in confined panel spaces. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in general-purpose electronic assemblies. The series offers various position counts and mounting styles to suit different board densities. As a dual-edge connector, it provides bidirectional access or increased pin density compared to single-edge variants.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 66-position dual configurations and 3.96 mm pitch. Verify mechanical dimensions and mounting hole patterns to ensure physical compatibility. Electrical ratings must match or exceed the original specifications.
