Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm that the specific suffix matches the required pin count and termination style. Request original manufacturer documentation to validate RoHS compliance and material specifications. Ensure storage conditions prevent moisture absorption in the thermoplastic housing prior to assembly.

Edgeboard Connectors Selection Notes

Select this model when a 66-position dual-row interface is required with a 3.96 mm pitch. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance range. Consider the vertical panel mounting orientation during mechanical layout. Compare against other 305 series variants if different position counts or termination types are needed.
