AI replacement insight
Electrical riskmedium
Resistance value differs, which may affect circuit timing, gain, or biasing. Validation is required.
Package risklow
All suggested alternatives share the same 0402 package, ensuring physical compatibility.
Sourcing risklow
Alternatives are from major manufacturers and are widely available.
Can it be replaced directly?
No direct drop-in replacement with the exact 3.83kΩ resistance was found. The closest alternatives are standard values like 3.9kΩ or 3.74kΩ, which require engineering review.
Best replacement path
Use a 3.9kΩ 1% 0402 resistor like Yageo's AC0402FR-073K9L, but verify circuit tolerance for the +1.8% resistance shift.
Main risk
The primary risk is the resistance deviation from the original 3.83kΩ value, which could alter circuit performance in sensitive applications.
