AI replacement insight

Package riskhigh

Target is Radial (through-hole), while most alternatives are SMD, requiring board redesign.

Electrical riskmedium

Candidates may have different capacitance, ESR, or ripple current ratings that must be verified.

Sourcing risklow

Multiple vendors offer functionally similar parts in various packages.

Can it be replaced directly?

There are no verified direct drop-in replacements for 118EC228. The closest form-factor match has a different capacitance, and all electrically similar parts have a different (SMD) package.

Best replacement path

For existing PCBs, evaluate SPT1CM271E080R, checking if the 23% higher capacitance is acceptable. For new designs, consider SMD functional alternates like XT220UF16V90RV0107.

Main risk

The primary risk is package incompatibility, as the target is a through-hole radial part and most available alternatives are surface-mount (SMD).
