Electrically similar with tighter tolerance, but is Not For New Designs (NRND).
Best Alternatives to CGA0402C0G390J500GT
Finding a substitute for the HRE CGA0402C0G390J500GT 39pF 50V 0402 capacitor involves checking parametric alternatives. Several options exist with the same package and voltage rating but may require design validation due to capacitance differences or lifecycle status.
AI replacement insight
Electrical riskmedium
Capacitance difference requires circuit validation.
Package risklow
All candidates share the 0402 package.
Sourcing riskhigh
One electrically identical option is NRND.
Can it be replaced directly?
No direct, drop-in replacement is confirmed. The closest electrical match is Not For New Designs (NRND), and other active parts have different capacitance values.
Best replacement path
Use an active 0402 50V C0G capacitor with the closest available capacitance (e.g., 33pF or 47pF) and verify circuit performance.
Main risk
The primary risk is functional failure due to capacitance mismatch if using parametric alternatives.
