AI replacement insight
Electrical riskmedium
High for downgrades, low-to-medium for parametric changes. Depends on circuit sensitivity.
Package risklow
All candidates share the same 0402 package.
Can it be replaced directly?
No direct drop-in replacement has been identified. All candidates require review due to differences in resistance, tolerance, or TCR.
Best replacement path
Use another Yageo RT series resistor like RT0402BRD0720K5L (20.5kΩ) if a small resistance change is acceptable.
Main risk
The primary risk is substituting a general-purpose resistor for this precision part, leading to degraded circuit performance due to wider tolerance and higher temperature drift.
