ERS1JM471K20OT is a 470uF 63V AISHI radial electrolytic with 13x20mm size and 10000h life. Current alternates need review for fit or capacitance changes.

AI replacement insight

Electrical riskhigh

Some options change capacitance or voltage margin.

Package riskhigh

One 470uF option is 16x25mm with 7.5mm pitch.

Firmware risklow

Passive part; no firmware impact expected.

Sourcing riskmedium

Candidates are indexed but not datasheet-checked.

Can it be replaced directly?

Direct replacement for ERS1JM471K20OT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Check ERS1KM221K20OT only if 220uF is acceptable, or EWH1KM471L25OT if a larger footprint can fit.

Main risk

Capacitance, endurance, ESR/ripple, and footprint are not all aligned.
