Functional alternative with higher voltage rating but a different package that requires layout verification.
Reviewing alternatives for the KNSCHA RST22UF35V025, a 22µF 35V aluminum electrolytic capacitor in a 5x5.4mm SMD package. Key considerations for substitutes include package size and voltage rating.
All candidates are larger than the target and may not fit the existing PCB footprint.
Candidates have matching primary specs and higher voltage ratings, which is generally safe.
No direct drop-in replacement is confirmed. All potential substitutes have different physical dimensions requiring layout review.
Select a candidate with a higher voltage rating (e.g., 50V) but first verify its larger package (e.g., 6.3mm diameter) fits your PCB layout.
Package mismatch is the primary risk, potentially requiring a PCB redesign.

Lelon's VZH220M1HTR-0606L and VES220M1HTR-0605 are potential functional alternatives with a higher 50V rating. However, their packages (6.3mm diameter) are larger than the 5mm target and require PCB layout verification.
