Finding a substitute for the CX KM478M025K25RR0VH2FP0, a 4700uF 25V radial capacitor, involves checking physical dimensions. Several alternatives offer higher voltage ratings but may require layout adjustments.

AI replacement insight

Package riskhigh

Most alternatives have different can sizes or lead spacing, requiring PCB layout and clearance checks.

Electrical riskmedium

Some options have lower capacitance, which requires circuit analysis to ensure stability and performance.

Sourcing risklow

Multiple manufacturers offer functionally similar parts, though physical fit varies.

Can it be replaced directly?

No drop-in replacement found. All reviewed options have different physical dimensions or electrical parameters requiring engineering review.

Best replacement path

Upgrade voltage while verifying physical fit. EWH1VM472M35OT is the most promising path if vertical clearance allows for a longer capacitor.
