AI replacement insight
Electrical riskmedium
Saturation current is unknown. For signal filtering this is low risk, but for power applications it is high risk.
Package risklow
Multiple candidates share the standard 2012 (0805) package, ensuring physical compatibility.
Sourcing risklow
Alternatives are available from major manufacturers like TDK and Sunlord, improving supply chain resilience.
Can it be replaced directly?
Yes, TDK's MLF2012C330KT000 is a potential pin-to-pin replacement. It matches the 33µH inductance, ±10% tolerance, and 5mA current rating in the same 0805 package, with the benefit of lower DCR.
Best replacement path
Start with Datasheet verified or Strong match candidates for SCL2012T330KSP, then review parametric alternatives for package and electrical fit.
Main risk
The primary risk is the unspecified saturation current (Isat) for both the original part and most alternatives, which is critical if the inductor is used in a DC-DC converter or subject to high peak currents.
