AI replacement insight

Electrical riskmedium

Substituting with a lower temperature part is a high risk. ESR/ripple differences can also impact performance.

Package risklow

The 8mm x 10.2mm SMD package is standard and widely available.

Can it be replaced directly?

Yes, direct replacements exist, but careful verification is required. The ROQANG RT1V221M0810 is a strong candidate for a direct, upgraded replacement.

Best replacement path

The ideal replacement is an upgrade within the same manufacturer series, like the RT1V221M0810, which improves voltage margin.

Main risk

The primary risk is substituting with a capacitor that has a lower maximum operating temperature, which could lead to premature failure.

Recommended alternatives

Upgrade path from the same manufacturer with a higher voltage rating (35V) and identical package.
