Nichicon UWT may work only after PCB and ESR review.
CA45-B6R3K107T is a 100uF 6.3V B-case MnO2 tantalum capacitor. The reviewed aluminum electrolytics are not drop-in replacements.
ESR, leakage, ripple, and tolerance differ.
Candidates are radial can SMD sizes, not B-case.
Passive part; no firmware impact expected.
All kept items are active but need FAE approval.
Direct replacement for CA45-B6R3K107T should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
