KEMET
Same-series 220 uF 16 V option, but the X case must be checked.
T491D227K016AT has no confirmed pin-compatible replacement in this set. Several 220 uF 16 V tantalum options need package, ESR, and derating review.
ESR and leakage need checks.
Many candidates are 7343-43 or missing package fields.
One close KEMET variant is obsolete.
No direct pin-compatible replacement is confirmed from the provided fields.
Start with KEMET T491X227K016AT if 7343-43 height is acceptable.
Case height and ESR differences can affect fit and circuit behavior.
