Is there a pin-compatible replacement for TCC0805X7R221K500DT?

No direct pin-compatible replacement has been verified. While CL21C221JBANNNC shares the same 0805 package and pinout, its C0G dielectric is electrically different from the target's X7R and requires engineering review before substitution.

What risks should I check before replacing TCC0805X7R221K500DT?

Before replacing, you must check three main risks: 1) Package mismatch, as some alternatives are in a smaller 0402 size requiring a new PCB layout. 2) Dielectric difference, as C0G has different stability characteristics than X7R. 3) Capacitance value, as some suggestions have a different capacitance.

TCC0805X7R221K500DT Alternatives, Datasheet & Cross Reference | CCTC

TCC0805X7R221K500DT is a standard 220pF, 50V X7R ceramic capacitor in an 0805 package. While no direct drop-in replacements have been identified, several functional and parametric alternatives are available that may offer upgrades in stability or a smaller footprint for redesigns.

AI replacement insight

Electrical riskmedium

Changing from X7R to C0G dielectric affects temperature and voltage stability. This may be an upgrade but must be verified.

Package riskhigh

Several alternatives are in a smaller 0402 package, which requires a PCB layout change and is not a drop-in replacement.

Sourcing risklow

The target and alternatives are from major manufacturers and appear to be active.

Can it be replaced directly?

No direct, drop-in replacement was found. All suitable alternatives require engineering review due to differences in dielectric material or package size.

Best replacement path

For applications where temperature stability is critical, CL21C221JBANNNC is an excellent upgrade. For new designs saving space, CL05B221KB5NNNC is an electrically identical option in a smaller package.

Main risk

The primary risks are electrical characteristic changes from using a different dielectric (C0G vs. X7R) and physical incompatibility from a different package size (0402 vs. 0805).

Recommended alternatives

A 220pF 50V capacitor in the same 0805 package but with a more stable C0G dielectric and tighter tolerance.
