AI replacement insight

Electrical riskmedium

Must match hold/trip current. Mismatch can lead to circuit damage or nuisance tripping.

Package risklow

1812 is a standard SMD package with consistent land patterns.

Sourcing risklow

Multiple vendors produce similar PTC fuses in this package and rating.

Can it be replaced directly?

Yes, mSMD110-24V by TECHFUSE is a strong candidate for direct replacement, matching the package, voltage, and current ratings.

Best replacement path

Prioritize candidates with an identical 1.1A hold current, such as mSMD110-24V or SMD1812-110C-33V, for direct functional replacement.

Main risk

The main risk is selecting a part with a higher hold current (e.g., 1.5A), which would reduce the level of overcurrent protection.
