Procurement Notes
Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches before procurement. Confirm RoHS compliance status if required by project regulations.
Selection Notes
Select this component when a high-density connection with 56 pins is required using a standard 0.156-inch pitch. The dual-edge design accommodates thicker boards compared to single-edge variants. Consider the panel-mount flange requirements for mechanical stability in the final assembly environment.
Part Context
This part belongs to the EDAC 306 Series, which provides a broad range of card edge connectors for various industrial applications. The series is known for its robust construction and standardized dimensions, facilitating integration into larger electronic systems requiring durable edge-board interfaces.
Replacement Considerations
Consult the EDAC 306 Series cross-reference documentation for direct substitutes. Verify that any alternative maintains the same 0.156-inch pitch, 56-position count, and dual-edge female configuration to ensure mechanical and electrical compatibility.
