Is there a pin-compatible replacement for 350AVCA470M0606E38?

No pin-compatible replacement has been verified. While some candidates have similar case dimensions, their land patterns are not confirmed to be identical and require engineering verification before use.

What risks should I check before replacing 350AVCA470M0606E38?

Key risks are electrical and mechanical. Electrically, verify the substitute's ESR and ripple current rating are acceptable, as electrolytic types differ from the original polymer capacitor. Mechanically, confirm the substitute's footprint matches your PCB layout.

Finding a substitute for the 350AVCA470M0606E38, a 35V 47uF polymer capacitor, requires careful review. Key considerations include matching the low ESR and high ripple current of polymer technology and verifying the 6.3mm x 5.8mm SMD footprint.

AI replacement insight

Electrical riskhigh

Technology mismatch (polymer vs electrolytic) impacts ESR, ripple current, and lifetime.

Package riskmedium

Some candidates have similar case sizes, but footprints are unverified and may not match.

Can it be replaced directly?

No direct, drop-in replacement has been verified. All candidates have different capacitor technology (electrolytic vs. polymer) and unverified footprints, requiring engineering review.

Best replacement path

The best path is to find another polymer capacitor with similar or better ESR and ripple current ratings. If using an electrolytic, VZH470M1VTR-0606 is a closer functional match but requires thorough testing.

Main risk

The primary risk is performance degradation due to higher ESR and lower ripple current capacity if replacing the target polymer capacitor with an electrolytic type.

Recommended alternatives

Functional alternative with similar package and low-ESR series, but requires review for exact ESR, ripple current, and footprint.
