Is there a pin-compatible replacement for RT1V221M0810?

Yes, several capacitors share the 8x10.2mm surface-mount package. However, you must verify secondary parameters like max operating temperature and ripple current, as many alternatives have a lower 105°C rating compared to the target's 125°C.

What risks should I check before replacing RT1V221M0810?

The primary risk is the maximum operating temperature; the target is rated for 125°C, while many alternatives are only rated for 105°C. Also check ripple current and ESR specifications to ensure reliability in your circuit.

RT1V221M0810 Alternatives, Datasheet & Cross Reference | ROQANG

The ROQANG RT1V221M0810 is a 220µF 35V aluminum electrolytic capacitor in an 8x10.2mm package, rated for high temperatures up to 125°C. Finding a direct replacement requires careful attention to both package size and temperature rating.

AI replacement insight

Electrical riskmedium

Voltage and capacitance can be matched, but temperature and ripple current may differ.

Package risklow

The 8x10.2mm package is common, but verify height and lead spacing from datasheets.

Can it be replaced directly?

No perfect drop-in replacement was found that matches all key parameters. The closest options require relaxing the maximum operating temperature from 125°C to 105°C.

Best replacement path

Prioritize candidates with 220µF capacitance and an 8x10.2mm package, then verify if a lower 105°C temperature rating is acceptable for the application.

Main risk

The most common risk is a lower maximum operating temperature (105°C vs 125°C), which could lead to premature failure in high-temperature environments.

Recommended alternatives

Matches package and capacitance with a higher voltage rating, but has a lower maximum operating temperature.
