Is there a pin-compatible replacement for 4701010812R00?

No drop-in, pin-compatible replacement is confirmed. The closest candidates require verifying physical dimensions (like diameter) or electrical performance (like ESR and ripple current).

What risks should I check before replacing 4701010812R00?

First, check physical fit: package diameter and lead spacing. Second, verify electrical performance; if using a standard electrolytic instead of polymer, check if higher ESR and lower ripple current are acceptable.

AI replacement insight

Package riskhigh

Candidates have different diameters or are different mounting types (SMD).

Electrical riskmedium

Switching from polymer to standard electrolytic or changing capacitance requires circuit analysis.

Can it be replaced directly?

No direct pin-to-pin replacement has been verified. Candidates have different physical dimensions, technology (electrolytic vs. polymer), or capacitance values.

Best replacement path

Find another 47uF 100V polymer capacitor in an 8mm radial package. AISHI SPZ1KM470G12O00RAXXX is close but its 10mm diameter requires a physical fit check.

Main risk

The main risks are physical incompatibility (package size) and electrical performance degradation (higher ESR, lower ripple current) if switching from polymer to standard electrolytic.

Recommended alternatives

Functionally similar polymer cap, but has a larger diameter (10mm vs 8mm). Check PCB clearance and lead spacing.
