Procurement Notes

Verify availability status carefully as this specific part number is officially listed as obsolete and no longer manufactured. Confirm technical compatibility with existing system requirements before considering alternatives. Review manufacturer documentation for any design changes or end-of-life notices that may impact long-term supply chain stability.

Selection Notes

Select this component only if the application specifically requires a 1.2 kA rating for three-phase delta configurations. Ensure the chassis mounting footprint and terminal block interface match the enclosure design. Consider the operating temperature limits and certification requirements such as cURus when integrating into the final equipment assembly.

Part Context

This filter belongs to the FN 5045 series from TE Connectivity Schaffner, specialized for heavy-duty power line filtering. The series is known for handling significant current loads in industrial environments. This specific model represents a high-capacity solution for delta-connected systems requiring robust EMI attenuation.

Replacement Considerations

TE Connectivity Schaffner recommends the FN5420-630-99-E0XXT as a substitute. Verify electrical specifications and physical dimensions to ensure compatibility with the original design constraints.
