Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact termination style, plating thickness, and housing material variations. Ensure that any selected variant matches the required panel mounting dimensions and PCB thickness tolerance. Cross-reference the part number with the latest datasheet to confirm compliance with RoHS directives and other relevant regulatory standards applicable to your region. Confirm availability status directly with authorized distributors as stock levels may fluctuate.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 68 contacts is required. The 3.96 mm pitch suits applications needing wider spacing for higher voltage isolation or mechanical stability. Verify that the target PCB thickness is exactly 1.57 mm to ensure proper retention force. Consider the 5 A current rating for power distribution needs within the module. Ensure the vertical panel mount style aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its suitability for demanding industrial and medical applications. The 305 series provides a range of position counts while maintaining consistent electrical ratings and mechanical specifications across the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different termination styles or keying options. Verify compatibility with existing PCB layouts and panel cutouts before swapping. No alternative cross-model replacements are confirmed in public documentation.
