Is there a pin-compatible replacement for 16V220uF CD288?

No direct pin-compatible replacement has been identified in this review. All candidates have a larger diameter (8mm or 10mm) than the original's 6mm, preventing a drop-in fit.

What risks should I check before replacing 16V220uF CD288?

The primary risk is physical incompatibility. You must verify the candidate's diameter and height fit your PCB layout. Also confirm that its superior electrical characteristics (lower ESR, higher ripple current) are acceptable for your circuit.

AI replacement insight

Package riskhigh

Candidates have 8mm or 10mm diameter vs. target's 6mm, preventing a drop-in fit.

Electrical risklow

Proposed alternatives are electrical upgrades (higher voltage, lower ESR), which is generally safe.

Can it be replaced directly?

No direct drop-in replacement has been identified. All suitable electrical alternatives have a larger physical package.

Best replacement path

Use an electrically superior part like CapXon KF221M035F115A, but only if the larger 8mm diameter package can be accommodated on the board.

Main risk

Physical package incompatibility; all reviewed candidates are wider than the target part and will not fit the same footprint.

Recommended alternatives

An electrical upgrade with much lower ESR, but its larger 8mm package requires physical fit verification.
