Hello, Welcome to the DigiKey TechForum. We have these 16v [capacitors](https://www.digikey.com/en/products/filter/aluminum-electrolytic-capacitors/58?s=N4IgjCBcpgnAHLKoDGUBmBDANgZwKYA0IA9lANogAMIAugL7EBMVALEtCGpFnkaRRABmIQAIArQDEQxMFSoTptYgAcALlBABVAHYBLNQHl0AWXyZcAVwBO%2BEIxAsA7B1QYcBYmUiUwANlEANTpVDUhtfSNTcytbe2IAWiZkLig1a0t%2Bb0oAVjoHBNdUyHTMr0EIBgdknxAAYQBBAAUGuoBJABVDACV8oA) at 33uf and 100uf. Not sure what a Z03 value would be. Any chance you can post photos of these parts so we can see the markings. ---

Hello Steve, Here is a pic. I appreciate your help! ![Inline image](https://global.discourse-cdn.com/digikey/original/3X/1/1/111bd9b735d10e8187a5bf95fb25afac0d1f3b47.png "Inline image") ---

Thanks for the photo, I searched to find the series from the markings but wasn’t able to. Looks like you have a 33uF cap rated at 100v, you can look through these [options](https://www.digikey.com/en/products/filter/aluminum-electrolytic-capacitors/58?s=N4IgjCBcoGwJxVAYygMwIYBsDOBTANCAPZQDaIALAAxwDMdIAuoQA4AuUIAymwE4CWAOwDmIAL6EwcABwJoIFJAw4CxMiCpMJIAExUKc5Gix5CJSOVq0ABAFaAYk1YdIIAKqD%2BbAPKoAsrjo2ACuvLjihHoA7IYKxipm6mBUVNYAak4g7JweXr4BQaHh2gC0OohxkHzBqubkAKxahCWxitW1SVra5RYK6CxaQA) , you will want to verify the dimensions to be sure one of these will fit. ---

Goodmorning Steve, thankyou for the information. There is another capacitor that I would like to confirm values . I did some research already but would like to make sure I am correct. See pic ![](https://global.discourse-cdn.com/digikey/original/3X/f/5/f5d9c1923889f90ad7a87f00c9ae6f3b690cc36e.jpeg) R3470c Ud Is this 47uf 16v? Many thanks! ![1693951303473blob.png](https://global.discourse-cdn.com/digikey/original/3X/1/1/111bd9b735d10e8187a5bf95fb25afac0d1f3b47.png) ---

Hello, This one looks like it’s from the UUD series manufactured by Nichicon based on the markings R3 is the lot number, 470 is the capacitance at 470uF and C is the voltage callout at 16v and UD is the UUD series as listed in the [datasheet](https://www.digikey.com/en/htmldatasheets/production/42670/0/0/1/uud0j270mcl1gs) . We have Digikey part number [493-2266-1-ND](https://www.digikey.com/en/products/detail/nichicon/UUD1C471MNL1GS/590007) available from that series, you will want to verify the dimensions on this one also. ---
