Functional alternative with a higher voltage rating but a larger package.
Finding a substitute for the CS1C220M-CRC54 22µF 16V capacitor involves balancing electrical upgrades with physical constraints. While several alternatives offer higher voltage ratings, the main challenge is their larger package size, requiring careful board layout review.
All candidates are physically larger than the target, requiring PCB layout changes.
Candidates have higher voltage ratings, which is a safe upgrade. Other key parameters match.
No, a direct drop-in replacement was not identified. All reviewed alternatives have larger physical packages that are not form-fit compatible with the original 4x5.4mm footprint.
The most promising alternative is VEJ220M1ETR-0506, which has a suitable 25V rating and the smallest package increase (5mm vs 4mm diameter). It still requires careful layout verification.

| Feature / factor | CS1C220M-CRC54 | VEJ220M1ETR-0506 | VZH220M1HTR-0606L | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 4x5.4mm | 5mm x 5.7mm | 6.3mm x 5.7mm | 5mm x 5.7mm / 6.3mm x 5.7mm — Candidate is larger, requires layout verification.; VZH220M1HTR-0606L: Candidate is significantly larger, requires layout verification. | |
| Voltage | 16V | 25V | 50V | 25V / 50V — Higher voltage rating provides more design margin.; VZH220M1HTR-0606L: Higher voltage rating provides more design margin. | |
| Capacitance | 22µF | 22µF | 22µF | 22µF — matched; VZH220M1HTR-0606L: matched | |
| Temperature | -40°C to +105°C | -55°C to +105°C | - | -55°C to +105°C — Wider operating range. |
The best functional alternative is VEJ220M1ETR-0506. It offers a higher 25V rating while having the smallest package difference (5x5.7mm vs 4x5.4mm), but you must verify it fits your PCB layout.
