AI replacement insight
Package risklow
All suggested alternatives share the same 6.3mm x 7.7mm SMD package and 2-pin layout.
Electrical riskmedium
Using a part with a significantly different ESR or ripple current rating can impact performance. Verification is required.
Sourcing risklow
This is a common capacitor value and package, with many alternatives available from multiple vendors.
Can it be replaced directly?
Direct replacement for CK1E101M-CRE77 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
For a direct, 1-to-1 replacement, KNSCHA XT100UF25V90RV0062 is the best choice. For a performance upgrade, consider the low-ESR NCC EMZA350ARA101MF80G.
Main risk
The primary risk is a mismatch in secondary electrical parameters like ESR (Equivalent Series Resistance) and ripple current, which can affect circuit stability and performance.
