UTT1E220MDD (DigiKey# 493-17310-ND) is a Nichicon capacitor that has been discontinued. However, if you need a replacement option part number 732-9277-1-ND should work for most cases. The main difference is that the 732-9277-1-ND is about 5.5mm taller than the original Nichicon part, so bear that in mind if you have a tight ceiling over your board.
If height is absolutely critical, then P14490-ND might work instead. This one still matches the critical performance specs, but it has a shorter expected lifespan than my first recommendation.
