ESR and the thermal budget — the spec that decides the fit
The TPSB336K010H0250: At 33 µF and 10 V rated, the 250 mOhm ESR is the number that governs ripple current handling. A lower-ESR part lets you push more AC ripple through the same case size before self-heating exceeds the 125°C limit; swapping in a higher-ESR substitute means derating the ripple or moving to a larger case.
Temperature range — military-grade, not just industrial
The 125°C ceiling matches the hot-end of a MIL-STD-883 screened assembly, not just an industrial motor drive.
