AI replacement insight
Electrical riskmedium
Some candidates have different resistance values or unspecified TCR, requiring validation.
Package risklow
All suggested alternatives use the same 0603 package, ensuring physical compatibility.
Can it be replaced directly?
Direct replacement for RC0603FR-074K02L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
0603WAF4021T5E is the strongest candidate, but requires review of its unspecified TCR and power margin.
Main risk
The primary risk is ensuring the substitute's Temperature Coefficient of Resistance (TCR) and power handling under load match the application's requirements.
