Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current series guide to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the part number with official distributor catalogs to validate current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this connector when a low-profile, dual-edge solution is required for standard thickness boards. Consider the 0.156-inch pitch for alignment with existing system layouts. Evaluate the operating temperature range against environmental conditions. Confirm that the panel mounting flange dimensions fit the enclosure design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, designed for high-reliability applications. The series offers various position counts and mounting options. It is engineered for durability in demanding environments, providing stable electrical connections for edge-board interfaces in critical infrastructure and electronic assemblies.

Edgeboard Connectors Replacement Considerations

Check the 305-014-521-202 for identical mechanical footprint and pin count differences. Verify the 315-014-521-278 if threaded flange mounting is preferred over the standard flange design. Ensure substitute parts maintain the same contact spacing and board thickness acceptance criteria.
