Electrical riskmedium
Capacitance differs by ~22% (1nF vs 820pF).
Package risklow
All suggested alternatives use the same 0603 package.
Sourcing risklow
1nF is a more common and widely available capacitance value than 820pF.
Can it be replaced directly?
No direct, drop-in replacement with identical capacitance was found. Alternatives with 1nF capacitance are available but require engineering review.
Best replacement path
Use a 1nF capacitor like 0603B102J500NT after verifying the circuit tolerates a ~22% capacitance increase.
Main risk
The primary risk is the change in capacitance, which can affect filter frequencies, timing constants, or circuit stability.
