AI replacement insight
Electrical riskhigh
Using a general-purpose (Thick Film, 1%) resistor will likely cause circuit failure or out-of-spec performance.
Electrical riskmedium
Using a part with a different resistance value requires recalculating circuit behavior.
Package risklow
All candidates use the same 0603 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, drop-in replacement is available in this list. All candidates have parametric differences requiring engineering review.
Best replacement path
Find a thin film 0603 resistor with 30.9kΩ resistance, 0.1% tolerance, and a TCR of 50ppm/°C or better. Power rating should be 0.1W or higher.
Main risk
The primary risk is performance degradation from using a substitute with wider tolerance, higher TCR, or a different resistance value, impacting circuit accuracy.
