Is there a pin-compatible replacement for JK-mSMD010-60?

Yes, several parts share the 2-pin 1812 package, making them physically compatible. However, key electrical parameters like hold and trip current differ, so they are not drop-in functional replacements and require engineering review.

What risks should I check before replacing JK-mSMD010-60?

The main risk is altered overcurrent protection. A substitute with a higher hold current will allow more current before tripping, potentially exposing downstream components to damage. Always verify the new current ratings against your circuit's safety requirements.

JK-mSMD010-60 Alternatives, Datasheet & Cross Reference | Jinrui Electronic Materials Co.

Finding a substitute for the JK-mSMD010-60 PTC fuse requires matching its 60V rating, 100mA hold current, and 1812 package. Alternatives exist but often have different current ratings that need verification.

AI replacement insight

Electrical riskmedium

Hold current mismatch is the primary electrical risk.

Package risklow

All viable candidates use the same 1812 package.

Can it be replaced directly?

No direct drop-in replacement was found. All viable alternatives have a higher hold current, which alters the circuit's overcurrent protection characteristics and requires engineering validation.

Best replacement path

Parametric alternatives with a slightly higher hold current, such as RUILON's SMD1812P014TF.

Main risk

A higher hold current reduces overcurrent protection sensitivity, potentially exposing downstream components to damaging currents.

Recommended alternatives

A potential alternative in the same 1812 package, but with a higher hold current that requires engineering review.
