Procurement Notes

Verify component status carefully as the 108R-473K is listed as discontinued or obsolete by major distributors. Confirm availability through secondary market channels or authorized stockists if immediate procurement is required. Ensure that any sourced units match the original manufacturing specifications to maintain circuit integrity.

Selection Notes

Select this component only when its specific 47 µH value and low current rating align with design constraints. Consider the unshielded nature for layout planning to minimize electromagnetic interference. Evaluate alternative available parts if long-term supply stability is a priority for the product lifecycle.

Part Context

This part belongs to the Delevan fixed inductor family, specifically designed for surface-mount technology. It serves as a passive component for energy storage and filtering in electronic circuits. The manufacturer API Delevan specializes in high-reliability magnetic components for various industrial and commercial applications.

Replacement Considerations

The TDK NLV25T-470J-EF is identified as a similar available substitute. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets the same mechanical and thermal requirements for the target application.
