A functional alternative with a higher voltage rating but a larger package that is not a drop-in replacement.
Finding a substitute for the KNSCHA 189RV0007, a 68µF 25V SMD capacitor, is challenging due to its compact 5mm package. While functional alternatives exist, none are direct drop-in replacements.
All viable candidates have a larger diameter (6.3mm vs 5mm) and will not fit the existing layout.
Key parameters like capacitance and temperature match, but ESR and ripple current must be verified.
No direct, drop-in replacement for 189RV0007 was found among the candidates reviewed. All viable options have different package sizes.
The closest functional alternatives, like ROQANG RVT1H680M0607, offer similar electrical performance but require a larger PCB footprint, necessitating a board redesign.
The primary risk is package mismatch. No candidates fit the target's 5mm x 5.7mm PCB footprint, making them incompatible without a board redesign.

| Feature / factor | 189RV0007 | RVT1H680M0607 | RVT1E680M0605 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 5mm x 5.7mm | 6.3mm x 7.7mm | 6.3mm x 5.4mm | 6.3mm x 7.7mm / 6.3mm x 5.4mm — Candidate is larger and will not fit the same PCB footprint.; RVT1E680M0605: Candidate has a larger diameter and will not fit the same PCB footprint. | |
| Voltage | 25V | 50V | 25V | 50V / 25V — Higher voltage rating provides increased design margin.; RVT1E680M0605: Identical voltage rating offers no additional safety margin. | |
| Capacitance | 68µF | 68µF | 68µF | 68µF — matched; RVT1E680M0605: matched | |
| Tolerance | ±20% | ±20% | ±20% | ±20% — matched; RVT1E680M0605: matched | |
