AI replacement insight

Electrical riskhigh

470uF or 1000uF differs from 680uF.

Package riskhigh

No candidate matches 12.5x20 exactly.

Firmware risklow

Passive capacitor; no firmware issue shown.

Sourcing riskmedium

Candidates are indexed and active.

Can it be replaced directly?

No pin-compatible replacement is verified from the provided evidence.

Best replacement path

Start with radial 5mm-lead candidates, then verify capacitance, ESR, ripple, life and clearance.

Main risk

Capacitance and mechanical mismatch.
