Procurement Notes

Verify component status as the 108-183JS is officially obsolete and no longer manufactured. Confirm availability through authorized distributors or secondary markets. Ensure replacement components meet identical electrical specifications and mechanical footprint requirements for successful integration into existing designs.

Selection Notes

Select this component only if legacy compatibility is required. Evaluate alternative surface-mount inductors with matching 18 µH inductance and similar current ratings. Verify that the unshielded design does not interfere with nearby sensitive circuitry. Check RoHS compliance status against current regulatory standards before procurement.

Part Context

This part belongs to the Delevan 108 series of fixed inductors. These components are characterized by their compact SMD form factor and iron core construction. The series was historically used in various electronic devices requiring small-value inductance for filtering and impedance matching purposes.

Replacement Considerations

Public confirmed substitute: NLV25T-180J-EF (TDK). This alternative offers comparable inductance and is available from major distributors.
