Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination type and mounting variations. Ensure compatibility with target PCB thickness specifications prior to ordering. Confirm RoHS compliance status through manufacturer datasheets. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate electrical ratings against application requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 18-position interface with 3.96 mm spacing is required. Consider the 5 A current rating and 1800 VACrms voltage capability for appropriate load handling. Evaluate the panel mount orientation and solder lug termination against assembly constraints. Verify that the operating temperature range meets environmental demands. Compare physical dimensions with available space on the host chassis.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various mounting options and row configurations. The series supports different position counts while maintaining consistent pitch and electrical characteristics. It serves as a standard solution for connecting edge-board modules to backplanes or chassis-mounted headers in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part number 305-018-555-208 and 305-018-555-203. These alternatives share identical positional and pitch specifications but may differ in termination style or housing color. Verify mechanical fit and electrical ratings before substitution.
