AI replacement insight
Electrical riskmedium
Resistance difference requires circuit analysis.
Package risklow
All viable candidates are in the same 0603 package.
Sourcing risklow
Many manufacturers produce similar 0603 resistors.
Can it be replaced directly?
No direct, drop-in replacement has been identified. All candidates require review due to differences in resistance or other parameters.
Best replacement path
Parametric alternatives with slightly different resistance values (e.g., 165Ω or 180Ω) are available. UNI-ROYAL 0603WAF1650T5E is a close match at 165Ω.
Main risk
The primary risk is the resistance value mismatch. The target's 169Ω is a non-standard E96 value, so substitutes are typically standard E24/E96 values like 165Ω or 180Ω.
