Matches package and inductance, but has higher DCR and a more limited temperature range.
Finding a substitute for the TDK MLF2012C330KT000 33µH 0805 inductor requires careful review of DC resistance (DCR), temperature range, and SRF. While several parts share the same package, key performance parameters often differ.
DCR, temperature, and SRF differences require validation.
Several candidates match the 0805 package.
No direct drop-in replacement has been identified; all candidates have parametric trade-offs requiring engineering validation.
form_fit_function candidates like SDFL2012T330KTF, but requires careful review of weaker parameters.
Electrical performance degradation, primarily from higher DC resistance (DCR) or a narrower operating temperature range.
