Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating thickness and insulation material variants. Ensure the ordering part number matches the required pin count and row configuration precisely. Cross-reference the datasheet for environmental ratings such as operating temperature range and RoHS compliance status before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required with a 3.96 mm pitch. Confirm that the target printed circuit board thickness aligns with the connector's mechanical constraints. Evaluate the 5 A current rating against system power requirements. Ensure the straight mounting style fits within the available chassis depth and panel cutout dimensions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by robust thermoplastic housings and standardized spacing. It serves as a reliable solution for connecting edge-board modules in compact electronic assemblies where space efficiency and connection stability are critical.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series family sharing identical pin counts and pitch, such as 305-072-521-204 or 305-072-521-508, provided the suffix variations match the required plating and housing specifications.
