Functionally similar 2kV 1nF capacitor in a smaller 1206 package with wider tolerance.
Find substitutes for the FV43X102K202ECG, a 2kV, 1nF, X7R ceramic capacitor in an 1812 package. Review functional alternatives and assess risks like package size and voltage ratings before replacement.
No candidates match the 1812 package, requiring PCB layout changes.
Candidates may have wider tolerance or lower voltage, requiring circuit validation.
No direct, drop-in replacements for FV43X102K202ECG were found. All viable alternatives require engineering review for package and parametric differences.
Use a functional alternative like NV1206B102M202CEDN, which matches the 2kV rating, but requires a PCB layout change for its smaller 1206 package.
The primary risk is mechanical incompatibility due to package size differences (e.g., 1812 vs 1206), which necessitates a board respin.
