Housed in the 2917 (7343 Metric) case with manufacturer size code E, measuring 7.30 mm x 4.30 mm and a seated height of 4.30 mm max. The molded case is general-purpose rated and compatible with standard reflow profiles.
This makes it suitable for avionics, downhole, and satellite applications.
A ceramic replacement would need to match the 33 µF capacitance at 25 V bias in a similar footprint, but ceramic capacitors exhibit DC bias derating (capacitance drops with applied voltage) and different temperature characteristics (X7R or X7S). Tantalum capacitors like this one maintain capacitance across the rated voltage range and have a different failure mode (short-circuit vs. open). A direct substitution requires careful review of the circuit's ESR, ripple current, and failure-tolerance requirements.
