[PYB20-Q24-S12](https://www.digikey.com/en/products/detail/bel-power-solutions/PYB20-Q24-S12/4289507) is a board mount power supply from [Bel Power Solutions](https://www.digikey.com/en/supplier-centers/bel-power-solutions) that has been discontinued. After some searching I found that [1470-2134-5-ND](https://www.digikey.com/en/products/detail/xp-power/JTM2024S12/4488513?s=N4IgjCBcoKxaBjKAzAhgGwM4FMA0IB7KAbRAGYBOGAdhgAYR9KaaQBdfABwBcoQBlbgCcAlgDsA5iAC%252B%252BMADZ4IJJDRY8hEiABM8%252BTAqKOIHn0GjJM-ABZF0ZSgw58RSKTDbtMXY3Cfv1L7yYNSGvh5eZAxy-mTW4bGKMZEAHAmRFOkw1hDJ2dpZ2YVweTBGXLyQAsLiUrLgKWRKKmrOmm7kwQHsFWY1lvVeBfYtThqupNoewYH4U9rW1tE6HtZxPSaV1RZ1%252BDRNI47qLlpgFNRk1MtTMFElOtQ5YNe0evfa1PIUC74fKWApJIPFIpGC5HQpT6XXxUL7xOR0eR0H5yMAAujvMBkfQMYymKrmWpWEDnQKHVRjE4dbQUMgfTJMOgYjy%252BKKIzwbfHbIn1NHaBjk1rjLQ0LGZPFbQkDOTWagQQWU9qkb7eBk6CgpbRkNKM7LUHUQnLeTmS-q7cDeOAK45KkCQuVpCV9HbEgEpAWII5tCbkRZo8qbZ08uQazLW71aXGDKbyz0Um0%252BiBOqoAOQArgBbbCiJD1AC0YbjwjTwo6SfzwyLQhLVNIcDY0kbQA) from [XP Power](https://www.digikey.com/en/supplier-centers/xp-power) should be a good alternative for this obsolete part.
