Procurement Notes

Verify the component status as End-of-Life (EOL) through official manufacturer notifications or authorized distributors. Confirm RoHS compliance status, which indicates lead content, against project requirements. Ensure the supplier provides valid traceability documentation for this discontinued part number before finalizing procurement decisions.

Selection Notes

Select this component when a precise 39 µH inductance is required for SMT RF designs. Consider the 17 Ohm DC resistance and 75 mA current limit for power handling. Evaluate the 10 MHz self-resonant frequency to ensure suitability for the target operating band. Compare physical footprint constraints against available PCB space.

Part Context

The 106-393F belongs to the Delevan 106 series of fixed surface-mount inductors. This series utilizes iron core technology designed for general-purpose and RF applications. The component represents a standard industry form factor for high-inductance SMD chokes, distinct from shielded variants found in other product lines.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the End-of-Life status. Designers must evaluate mechanical compatibility and electrical equivalence manually if sourcing alternatives from other manufacturers.
