AI replacement insight
Electrical riskmedium
Risk is low for exact matches, but medium to high for parametric alternatives with different resistance or technology.
Package risklow
All suggested alternatives are in the same 0402 package, minimizing layout changes.
Sourcing risklow
The target and top alternatives are from major manufacturers, but stock should always be verified.
Can it be replaced directly?
Yes, Yageo's AC0402FR-074K3L is a pin-to-pin replacement with matching resistance, tolerance, power rating, and package.
Best replacement path
For a direct drop-in, use AC0402FR-074K3L. For a high-precision upgrade, consider RT0402BRD074K3L but verify technology impact.
Main risk
The main risk is selecting an alternative with a different nominal resistance or technology (thin vs. thick film) without validating circuit performance.
