Is there a pin-compatible replacement for S07F1E222MN0B0S0N0?

Yes, several parts share the same disc package, but no identified part is a direct electrical drop-in. All candidates require review due to different dielectric materials.

What risks should I check before replacing S07F1E222MN0B0S0N0?

The main risk is the different dielectric (Y5V vs. Y5U), affecting capacitance over temperature. Also, verify the physical dimensions (diameter, lead spacing) of higher voltage parts.

S07F1E222MN0B0S0N0 Alternatives, Datasheet & Cross Reference | STE

Finding a substitute for the STE S07F1E222MN0B0S0N0, a 2.2nF 3kV Y5U ceramic capacitor, requires careful attention to the dielectric material. While alternatives with higher voltage ratings exist, their temperature characteristics differ significantly.

AI replacement insight

Electrical riskhigh

Dielectric mismatch (Y5V vs Y5U) significantly impacts temperature stability.

Package risklow

Package is the same type, but higher voltage parts may be physically larger. Verify dimensions.

Sourcing riskmedium

Finding an exact match with Y5U dielectric at this voltage may be difficult.

Can it be replaced directly?

No direct drop-in replacement has been identified. Available alternatives have a different dielectric (Y5V), which has poorer temperature stability than the original Y5U.

Best replacement path

Search for capacitors with 2.2nF capacitance, ≥3kV voltage, and a Y5U or better (e.g., X7R) dielectric in a compatible disc package.

Main risk

The primary risk is the dielectric mismatch (Y5V vs. Y5U), which can cause unexpected capacitance changes with temperature, potentially affecting circuit performance.

Recommended alternatives

A 2.2nF capacitor with a much higher 6kV rating but a different dielectric (Y5V vs Y5U). Requires review for temperature and size constraints.
