Best Alternatives to KM476M100F12RR0VH2FP0
Finding a replacement for the CX KM476M100F12RR0VH2FP0 47uF 100V capacitor involves matching its radial package and electrical specs. Alternatives exist with identical ratings, but may use different technologies or have different packages requiring careful review.
AI replacement insight
Package riskhigh
Many alternatives are SMD or have different dimensions, requiring board changes.
Electrical riskmedium
Closest matches may use different capacitor technology (polymer), affecting ESR and ripple current ratings.
Can it be replaced directly?
Direct replacement for KM476M100F12RR0VH2FP0 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The NJCON 4701010812R00 is the closest match in form and key parameters, but uses polymer technology requiring ESR verification.
Main risk
The primary risk is package incompatibility for functional alternates, or subtle electrical differences (like ESR) for form-fit candidates.
