Is there a pin-compatible replacement for RT1C221M0607?

Several parts like VT1C221M0607 and VEJ221M1CTR-0607 are pin-compatible in the same package, but they are not direct replacements due to a lower 105°C temperature rating compared to the original's 125°C.

What risks should I check before replacing RT1C221M0607?

The main risk is the lower maximum operating temperature of all available alternatives (typically 105°C vs 125°C). You must verify that your circuit's operating temperature will not exceed the new part's limit. Also check secondary parameters like ESR and ripple current from the datasheets.

RT1C221M0607 Alternatives, Datasheet & Cross Reference | ROQANG

Finding a substitute for the RT1C221M0607 requires careful attention to its high 125°C temperature rating. While several parts match its 220µF capacitance, 16V rating, and 6.3x7.7mm package, most alternatives are limited to 105°C.

AI replacement insight

Electrical riskmedium

Temperature downgrade is a reliability risk. Secondary parameters like ESR may differ.

Package risklow

All suggested alternatives share the same package dimensions and mounting type.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates have a lower maximum temperature rating than the original part.

Best replacement path

Consider RVT1V221M0607 for its higher voltage rating (35V), but you must validate its lower 105°C temperature limit for your design.

Main risk

The primary risk is thermal. Replacing a 125°C capacitor with a 105°C part without analysis can lead to premature failure.

Recommended alternatives

A form-fit alternative with a higher 35V rating, but a lower 105°C max temperature compared to the target's 125°C.
