AI replacement insight

Electrical risklow

Low if secondary parameters like ESR and ripple current are met or exceeded. Capacitance must match for most applications.

Package risklow

Low, as several candidates share the same 6.3mm x 7.7mm SMD package, ensuring mechanical compatibility.

Sourcing riskmedium

Availability of specific series can vary. Cross-vendor options may require more validation of secondary parameters.

Can it be replaced directly?

Direct replacement for 189RV0018 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most direct path is using KNSCHA 189RV0017, which is an electrical and mechanical match with an improved ripple current rating.

Main risk

The primary risk when substituting is selecting a part with incorrect capacitance, which can alter circuit behavior like timing or filter response.
