Is there a pin-compatible replacement for ERE1EM471G13OT?

While several parts share the same 10x13mm radial package, differences in load life or capacitor technology mean they are not guaranteed drop-in replacements. Engineering review is required to confirm pin-to-pin compatibility in your circuit.

What risks should I check before replacing ERE1EM471G13OT?

Key risks include shorter load life, which impacts product reliability, and different capacitor technology (e.g., polymer vs. electrolytic), which affects ESR, ripple current, and leakage. Always verify these against your circuit's requirements.

AI replacement insight

Electrical riskmedium

Candidates may have different load life, ESR, or leakage current.

Package risklow

Several candidates match the radial through-hole package.

Can it be replaced directly?

No direct drop-in replacement was identified. All strong candidates have notable differences, such as shorter load life or different capacitor technology, which require engineering validation.

Best replacement path

For improved performance, consider a polymer capacitor like KNH2470UF35V149EC0017 after engineering review. For a similar technology, EWH1VM471G13OT is an option if shorter load life is acceptable.

Main risk

The primary risk when substituting is a mismatch in load life, which affects reliability, or a change in capacitor technology, which impacts electrical characteristics like ESR.

Recommended alternatives

Form-fit match with higher voltage but different capacitor technology and shorter life; requires review.
