Is there a pin-compatible replacement for 189RV0034?

No pin-compatible (drop-in) replacement has been verified. All reviewed candidates have different package types or dimensions, requiring PCB layout verification and likely redesign.

What risks should I check before replacing 189RV0034?

The main risk is the package size and PCB footprint; verify the candidate's dimensions (DxL) against your layout. Also check secondary parameters like lifetime (endurance) and ripple current ratings.

189RV0034 Alternatives, Datasheet & Cross Reference | KNSCHA

Finding a replacement for the KNSCHA 189RV0034 capacitor requires careful checking of package dimensions. While alternatives with similar electrical specs exist, footprint compatibility is a key challenge.

AI replacement insight

Package riskhigh

Most alternatives are through-hole or larger SMD parts that will not fit the target's footprint.

Electrical risklow

Candidates with matching primary electrical parameters (V, C, Tol) are available.

Can it be replaced directly?

No direct, pin-compatible replacement has been identified. All reviewed candidates require verification of the PCB footprint due to package differences.

Best replacement path

Find a 1000uF, 25V capacitor in an identical 10mm x 10.5mm SMD package, verifying ripple current and lifetime.

Main risk

The primary risk is physical incompatibility; most alternatives have different package types or larger dimensions, requiring a PCB redesign.

Recommended alternatives

Functional alternative with matching electricals but a larger SMD package requiring PCB layout changes.
