We do not currently stock part number [P66A-5P2J](https://datasheet.octopart.com/P66A-8P2J-Mean-Well-datasheet-15992359.pdf) from [Mean Well](https://www.digikey.com/en/supplier-centers/mean-well), but after some searching I have found a possible alternative.

[179-SDI65-18-U-P5-ND](https://www.digikey.com/en/products/detail/bel-power-solutions/SDI65-18-U-P5/5297504?s=N4IgTCBcDaIIwHYCcBaAygEQJIDYCsKcAHCgKooAKBAchiALoC%252BQA) (made by [Bel Power](https://www.digikey.com/en/supplier-centers/bel-power-solutions)) is a similar power supply that meets the majority of specifications as the original, though it has a slightly lower maximum output current at 3.62A versus the P66A-5P2J’s 3.66A.
