AI replacement insight

Electrical riskmedium

Some alternatives have lower current ratings, risking nuisance trips.

Package risklow

All viable candidates share the same 1206 package.

Can it be replaced directly?

Yes, SMD1206P012TF is a potential pin-to-pin replacement, matching the 120mA hold current, 60V rating, and 1206 package. However, verification of the full datasheet is required.

Best replacement path

RUILON SMD1206P012TF offers a near-identical parametric match and is the strongest candidate for replacement.

Main risk

The primary risk is substituting with a part that has lower hold/trip currents, which could lead to nuisance tripping in the application.
