For a 10 V rail with 100 mV ripple, the 220 µF delivers about 140 mA ripple current before the internal temperature rise becomes a concern.
The D case size (2917 metric 7343) is a standard tantalum footprint — 7.30 mm x 4.30 mm body, 3.10 mm seated height. At 125°C, the voltage rating should be derated per the manufacturer's guidelines (typically 50% for tantalum), so the 10 V part is good for a 5 V rail at high temperature.
Functionally, any 220 µF, 10 V tantalum in a 2917 D case with ±10% tolerance and 500 mOhm ESR is a direct electrical equivalent. The molded construction and TAJ series designation are specific to KYOCERA AVX, but the parametric match is what matters for the BOM line. Confirm the ESR and temperature range before substituting.
