The TPSB336K010B0650: 33 µF at 10 V gives you a 2.5 V derating margin below the rated voltage — standard practice for tantalum caps to avoid field-failure from voltage surges. The molded TPS series is the general-purpose workhorse for decoupling and bulk storage on power rails up to 10 V.
The molded epoxy case handles the thermal cycling without cracking the anode.
1411 (3528 Metric) B case — 3.50 mm x 2.80 mm footprint, 2.10 mm seated height. Surface-mount, compatible with standard reflow profiles. The B case is one of the most common tantalum sizes; your existing 1210/3528 pad layout works without a footprint change.
No immediate end-of-life risk for new designs.
