Same package and capacitance, but different dielectric (X7S) requires review of temperature stability.
The TDK C3216X7R1E335KT000N is a general-purpose 3.3µF, 25V, X7R ceramic capacitor in a standard 1206 package, widely used for decoupling and filtering applications.
Capacitance or dielectric changes require circuit analysis.
All candidates share the same 1206 package.
Multiple active alternatives are available from major manufacturers.
No direct drop-in replacement was found. All candidates have significant parametric differences requiring engineering validation.
Evaluate candidates with higher capacitance (4.7µF) for decoupling, or the X7S part if temperature stability is not critical.
The primary risks are either a mismatch in capacitance value or a change in the dielectric material's temperature characteristics.

Same package and capacitance, but different dielectric (X7S) requires review of temperature stability.
