Is there a pin-compatible replacement for FS43X226K250EGG?

Yes, several capacitors share the 1812 package, making them physically compatible. However, electrical parameters like tolerance (C4532X7R1E226MT000N) or dielectric (FS43X226K500ERG) may differ, requiring engineering review.

What risks should I check before replacing FS43X226K250EGG?

Key risks include changes in capacitance tolerance, which can affect circuit timing or filtering, and differences in dielectric material (e.g., X5R vs. X7R), which impacts temperature stability and operating range.

AI replacement insight

Electrical riskmedium

Tolerance or dielectric changes require circuit analysis.

Package risklow

All candidates share the same 1812 package.

Can it be replaced directly?

No direct drop-in replacement without caveats has been identified. All viable candidates require engineering review of either tolerance or dielectric material.

Best replacement path

C4532X7R1E226MT000N is the closest functional match if the wider ±20% capacitance tolerance is acceptable for the application.

Main risk

The main risks are accepting a wider capacitance tolerance (±20% vs ±10%) or a different dielectric (X5R vs X7R) with a more limited temperature range.

Recommended alternatives

A 22µF, 25V, X7R capacitor in an 1812 package with a wider ±20% tolerance. Review required for precision applications.
