Strong candidate matching package, capacitance, and voltage. Verify ESR and ripple current before use.
Finding a substitute for the KNSCHA RVT22UF63V67RV0002, a 22uF 63V capacitor, involves matching the 6.3x7.7mm SMD package and key electricals. Parameters like ESR and ripple current are critical for ensuring circuit stability.
Several alternatives have larger packages requiring board changes.
ESR and ripple current are critical and vary significantly between parts.
No direct, datasheet-verified drop-in replacement is confirmed. RVT1J220M0607 is the closest match but requires an engineering review of its ESR and ripple current specs.
Evaluate RVT1J220M0607 by ROQANG, which matches form and primary electricals. Datasheet verification of ESR and ripple current is the required next step.
The main risk is substituting with a part that has a significantly higher ESR, which could compromise performance and reliability, even if primary ratings match.
