AI replacement insight

Electrical riskhigh

Most alternatives have weaker tolerance (5% vs 1%) and lower power rating.

Package riskmedium

Many candidates are in smaller packages, requiring layout changes.

Can it be replaced directly?

No direct, fully equivalent replacement has been identified. The closest options have weaker tolerance or power ratings and require engineering review.

Best replacement path

Consider form-fit parts like RALEC's RTA03 series, but verify tolerance and power rating. Non-form-fit parts require a PCB redesign.

Main risk

The main risks are mismatched power ratings and resistance tolerances, which can affect circuit performance and reliability.

Recommended alternatives

Form-fit alternative with weaker tolerance and lower power rating; requires circuit analysis.
