Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before integration. Confirm that the straight mounting orientation aligns with the mechanical design constraints of the assembly. Cross-reference the 72-position count with schematic requirements to prevent pinout mismatches during procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 5 A current rating suits moderate power distribution needs. Verify that the operating environment stays within the specified -40 C to +105 C range. Consider the straight PCB mount style for direct board integration without angled adapters. Ensure the gold contact finish meets corrosion resistance standards for the intended application lifecycle.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-072-520-208 specifically addresses high-pin-count requirements in a compact form factor. It complements other EDAC products by providing standardized dimensions and electrical characteristics for system interoperability.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified equivalents. Generic substitutes may not match the precise 1.57 mm board thickness tolerance or gold plating specifications. Verify pin-to-pin compatibility and mechanical retention features before swapping components.
