AI replacement insight
Package risklow
All viable candidates use the same 2512 package.
Electrical riskmedium
Technology and parameter differences require circuit validation.
Can it be replaced directly?
No direct pin-to-pin replacement was found. All viable options require engineering review due to differences in technology, parameters, or qualifications.
Best replacement path
Upgrade to a 3W resistor like UNI ROYAL LR123WF200LT4E, but verify impact of Metal Strip technology and lack of AEC-Q200 rating.
Main risk
Key risks include technology mismatch (Thick Film vs. Metal Strip/Alloy) affecting pulse handling, and lack of AEC-Q200 automotive qualification.
