Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to ensure compatibility with required board thickness and mounting style. Confirm that the dual-edge receptacle type matches the target PCB design. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the operating temperature range meets the system requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 20 positions is required. The 3.96 mm pitch and 1.57 mm board thickness compatibility are critical constraints. Consider the panel mount capability if chassis integration is needed. Verify that the 5 A current rating suffices for the application's power distribution needs.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-020-521-512 specifically denotes a 20-position dual-edge variant. It is categorized under headers and receptacles for board-to-board or backplane connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the EDAC 305 series include variants with different position counts but matching pitch and board thickness. Cross-reference part numbers such as 305-020-520-512 for similar specifications. Ensure any replacement maintains the same row spacing and termination type.
