Is there a pin-compatible replacement for 189RV0017?

While several parts share the same package and pinout, no direct pin-for-pin replacement with identical key electrical parameters has been confirmed. All options require careful review.

What risks should I check before replacing 189RV0017?

Primarily check the ripple current rating (must be ≥600mA) and ESR (≤0.16Ω). Also, verify if your circuit tolerates a different capacitance value, as this is a common variation.

AI replacement insight

Electrical riskhigh

Ripple current and capacitance are critical and vary significantly among potential substitutes.

Package risklow

The 6.3mm x 7.7mm SMD package is common and candidates match the form factor.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates require review due to mismatches in ripple current or capacitance.

Best replacement path

A functional alternative like ACMECON's GVM1V227M0608CN matches key performance metrics but has higher capacitance, requiring design review.

Main risk

The primary risk is substituting a part with lower ripple current capability, which can lead to overheating and premature failure.

Recommended alternatives

Matches package, voltage, and ripple current, but has higher capacitance. Requires review before use.
