Molded tantalum, 33 µF, 6.3 V — the field-swap reality
The TPSB336M006R0450: This is a molded tantalum capacitor from the TPS series, rated 33 µF at 6.3 V with ±20% tolerance. The 450 mOhm ESR is the number that matters for ripple — if your 6.3 V rail sees switching noise, that ESR sets how much the cap warms up. The molded case means no conformal-coat worries; the part is self-shielding and the case is the pick-and-place datum.
The full temperature range is the reliability spec — no need to second-guess the cap in a harsh environment.
Package and mounting — 1411 (3528 Metric) B case
Surface-mount in a 1411 (3528 Metric) B case, 3.50 mm x 2.80 mm footprint, seated height 2.10 mm max. The case code B is standard for this capacitance and voltage — the pad layout is the same as any other B-case tantalum, so a second-source swap is a straight BOM edit.
