AI replacement insight

Electrical riskhigh

Using a higher current fuse negates overcurrent protection.

Package risklow

All candidates share the same 1206 package.

Can it be replaced directly?

No, there are no direct pin-compatible replacements in this list. All candidates have significantly different current ratings.

Best replacement path

No direct drop-in replacement was found. The best path is to select another 1A/63V slow-blow fuse in a 1206 package from a different manufacturer.

Main risk

The primary risk is using a fuse with a higher current rating, which will fail to protect the circuit at the designed 1A threshold.
