Overview
The EDAC Inc. 306-033-521-168 is a dual-edge card edge connector from the 306 Series, designed for high-reliability applications. It features a 0.156-inch (3.96mm) contact spacing and accommodates 66 positions with female contacts. The connector utilizes PC tail termination types and incorporates gold plating on the contact area to ensure stable electrical performance. The housing is green in color, providing visual identification within assembly environments.
Feature Summary
- Dual-edge configuration supporting simultaneous connection on both sides of a circuit board
- Gold-plated contact surfaces to maintain signal integrity and corrosion resistance
- PC tail termination style for secure mechanical mounting and reliable soldering
Applications
- High-density electronic module interconnections
- Industrial control system backplanes
- Telecommunications equipment card slots
Procurement Notes
Verify the specific series designation and contact count against official EDAC documentation before procurement. Confirm that the dual-edge requirement aligns with the target PCB design. Ensure the PC tail termination type matches the available mounting infrastructure. Cross-reference the 0.156-inch spacing to guarantee compatibility with existing card edge profiles.
Selection Notes
Select this component when a dual-sided connection interface is required for robust signal transmission. The 0.156-inch pitch offers a balance between density and manufacturability. Gold plating is essential for environments requiring long-term reliability without oxidation issues. Verify that the 66-position capacity meets the total I/O requirements of the application.
Part Context
This part belongs to the EDAC 306 Series, which specializes in card edge connectors with standardized spacing. The series is engineered for demanding industrial and commercial sectors where consistent performance under thermal and mechanical stress is critical. The dual-edge design distinguishes it from single-sided variants, offering increased connectivity options per unit footprint.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Consult EDAC technical support for direct equivalents or pin-compatible alternatives if this specific configuration is unavailable.
