Edgeboard Connectors Procurement Notes

Verify the specific suffix against official EDAC documentation to confirm exact contact termination style and flange characteristics. Confirm RoHS compliance status directly with the manufacturer or authorized distributor prior to procurement. Ensure the ordering part number matches the required pin count and row configuration for the target application.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current connection is required for thick PCBs. The 3.96mm pitch allows for substantial trace spacing. Verify that the mating card edge thickness aligns with the 1.57mm specification. Consider the polarizing key compatibility if precise orientation is critical for the assembly process.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its heavy-duty construction and high voltage ratings. It serves as a reliable interface solution for applications demanding durability and stable electrical performance under varying environmental conditions.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-070-520-268 for potential functional equivalents. Verify that any substitute maintains the identical 70-position count, dual-row layout, and 3.96mm pitch to ensure mechanical fit.
