CYA0650-68UH
SHOU HAN
Needs validationlow risk
A strong alternative with matching inductance and current, in a nearly identical 0650 package.
Best Alternatives to SMMS0650-680M
Finding a substitute for the SMMS0650-680M involves matching its 68µH inductance, 2.0A saturation current, and 0650 package. Several functional and pin-compatible alternatives are available, with CYA0650-68UH being a top candidate.
AI replacement insight
Electrical risklow
Several candidates match or exceed the target's key electrical specifications (Inductance, Isat).
Package riskmedium
Candidates exist with very similar package dimensions, but verification of the PCB footprint is critical.
Sourcing risklow
Alternatives are available from multiple manufacturers, indicating good supply chain options.
Can it be replaced directly?
Direct replacement for SMMS0650-680M should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
CYA0650-68UH by SHOU HAN is the most promising alternative, offering a near-identical package and matching key electrical specs. A footprint check is recommended.
Main risk
The primary risk when substituting inductors is physical incompatibility. Even with similar package codes, slight differences in dimensions or pad layout can prevent a drop-in replacement.
