AI replacement insight
Electrical riskmedium
Resistance value differs by ~9%, which may be outside the tolerance for some circuits.
Package risklow
All viable candidates use the same 2512 package, ensuring form and fit compatibility.
Can it be replaced directly?
No exact drop-in replacement was found. Several parts match the package, power, and tolerance, but have slightly different resistance values (e.g., 4.7Ω or 3.9Ω).
Best replacement path
Parametric alternatives with slightly different resistance values (e.g., 3.9Ω or 4.7Ω) are available and require circuit-level validation.
Main risk
The primary risk is the change in resistance value, which may affect circuit performance. A secondary risk is a potential mismatch in the Temperature Coefficient of Resistance (TCR).
