KNSCHA
Functionally similar with a matching voltage rating, but is taller and requires a physical clearance check.
Finding a substitute for the KNSCHA 126RV0120, a compact 220uF 16V capacitor, requires careful attention to package size. While functional alternatives with equal or better voltage ratings are available, they are typically larger and require board layout verification.
All candidates are physically larger, preventing a drop-in replacement.
Candidates have matching or superior voltage and capacitance ratings.
No direct drop-in replacement has been identified. All potential substitutes have different package dimensions that require user verification.
Functional alternate with package review
The primary risk is package mismatch. All candidates are larger than the target part, requiring PCB layout changes or clearance checks.
