Is there a pin-compatible replacement for JK60-185?

Yes, JK60-200 is considered a pin-compatible replacement. It has the same radial leaded package and pin count, with closely matched electrical characteristics.

What risks should I check before replacing JK60-185?

The main risks are functional and electrical mismatches. Ensure the replacement is a PTC resettable fuse, not a one-time fuse. Verify that the hold and trip currents are very close to the original 1.85A and 3.7A ratings to maintain the intended level of overcurrent protection.

Electrical riskhigh

Critical to match hold/trip current to ensure proper protection.

Package risklow

The radial leaded package is common and easy to match.

Can it be replaced directly?

Yes, the JK60-200 is a potential direct replacement for the JK60-185, sharing the same package, voltage, and similar current ratings.

Best replacement path

The best path is to use another part from the same JK60 series, like the JK60-200, which has nearly identical specifications.

Main risk

Using a part with a significantly different current rating, which would fail to protect the circuit as designed.

Recommended alternatives

A close parametric match from the same product series with identical package, voltage, and trip time.
