AI replacement insight
Electrical riskmedium
Resistance value differs, which can impact circuit performance. Risk level depends on circuit sensitivity.
Package risklow
All candidates share the same 0603 package, ensuring physical compatibility.
Can it be replaced directly?
No direct drop-in replacement with the exact 1.37kΩ resistance was found. All suitable alternatives have a different resistance value and require engineering validation.
Best replacement path
Select a candidate with the closest resistance value to the original 1.37kΩ, such as FRC0603F1401TS (1.4kΩ) or FRC0603F1331TS (1.33kΩ).
Main risk
The primary risk is the change in resistance, which could alter circuit timing, biasing, or feedback loops.
