Is there a pin-compatible replacement for CD288H1EM471F120T?

KM1E471M0812 has a compatible package and pinout (8x12mm, 3.5mm lead spacing), but its lower ripple current and higher ESR make it a high-risk downgrade, not a direct replacement.

What risks should I check before replacing CD288H1EM471F120T?

Verify the substitute's can diameter and lead spacing match your PCB layout. Critically, ensure its ripple current rating (in mA) and ESR (in Ω) meet or exceed your application's requirements.

Finding a substitute for the CD288H1EM471F120T 470µF 25V capacitor requires careful review of physical dimensions and electrical performance, particularly ripple current and ESR.

AI replacement insight

Package riskmedium

Candidates may have different can sizes or lead spacing.

Electrical riskhigh

Some candidates have significantly lower ripple current ratings.

Can it be replaced directly?

No direct drop-in replacement was found. KM1E471M0812 is a physical match but a performance downgrade, while KNE2470UF25V149EC0035 is an electrical upgrade but physically smaller.

Best replacement path

Find a part with 470µF/25V specs, 8x12mm can size, 3.5mm lead spacing, and ripple current ≥ 892mA.

Main risk

The main risks are physical incompatibility (wrong size/lead spacing) or electrical underperformance (lower ripple current handling).

Recommended alternatives

Electrically superior but physically smaller; requires layout check for its 6.3mm diameter and 2.5mm lead spacing.
