JK-MSMD110-24V is a 1.1A, 24V PTC resettable fuse in a standard 1812 package. When seeking alternatives, prioritize matching the 1.1A hold current and 1812 package, while ensuring the voltage rating is 24V or higher.

AI replacement insight

Electrical riskmedium

Using a part with a higher hold current will not protect the circuit as intended. A lower max fault current rating is a safety hazard.

Package risklow

The 1812 package is highly standardized, minimizing physical compatibility issues.

Sourcing risklow

Many manufacturers produce 1812 PTC fuses with similar ratings, ensuring a stable supply chain.

Can it be replaced directly?

Direct replacement for JK-MSMD110-24V should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Upgrade to JK-mSMD110-33 for a higher voltage rating from the same manufacturer, or use mSMD110-33V as a strong cross-vendor option.

Main risk

The primary risk is mismatching the hold current (Ih), which can compromise the circuit's overcurrent protection.
