AI replacement insight
Package risklow
All suggested alternatives are in the same 2512 package.
Electrical riskmedium
Risk is low for pin-compatible parts, but medium for parametric alternatives which have weaker tolerance and TCR.
Can it be replaced directly?
Yes, parts like FOJAN FRC2512F2002TS and UNI-ROYAL 25121WF2002T4E are verified pin-compatible replacements with matching resistance, tolerance, power, and package.
Best replacement path
Use pin-compatible options like FOJAN FRC2512F2002TS, which match all key electrical and physical specifications.
Main risk
The main risk is substituting with a part that has a wider tolerance (e.g., 5%) or higher TCR, which can affect circuit precision.
