This TDK inductor is a potential upgrade with a lower DCR in the same 0805 package.
Find suitable replacements for the Sunlord SDFL2012T330KTF, a 33µH 0805 multilayer inductor. We've analyzed several alternatives, including pin-compatible options and functional substitutes with detailed comparisons.
Key parameters like inductance, DCR, and rated current are well-matched by top candidates. Unspecified Isat is the main but minor gap.
Multiple candidates share the identical 2012 (0805) package, ensuring form-fit compatibility.
Alternatives are available from major manufacturers like TDK, indicating good supply chain options.
Direct replacement for SDFL2012T330KTF should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The TDK MLF2012C330KT000 is the best replacement, offering identical specs with a slightly better (lower) DCR.
The primary risk is a lack of specified saturation current (Isat) for both the target and most alternatives, which is a low risk for typical signal filtering applications but should be considered.

This TDK inductor is a potential upgrade with a lower DCR in the same 0805 package.
