KNSCHA 189RV0019 keeps 220uF and case size while raising voltage to 35V.
CK1C221M-CRE77 is a 220uF 16V SMD aluminum electrolytic capacitor in a 6.3x7.7mm case. Candidate replacements need polarity, footprint and ESR checks.
Check ESR, ripple and derating.
6.3x7.7mm must match pads and height.
Passive part; no firmware impact.
Kept candidates are indexed and active.
Direct replacement for CK1C221M-CRE77 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with 189RV0019 for voltage margin, or RVT220UF16V67RV0015 for same ratings; verify footprint and polarity.
Unverified pad polarity and case dimensions.
