Part number LCB150Q is obsolete. A possible alternative would be PMT-24V150W1AA. The Digi-Key part number would be 1145-1075-ND. There are very slight dimension differences. Some minor electrical differences like for example efficiency of 89% instead of 90%. The link for the product would be : https://www.digikey.com/products/en?keywords=1145-1075-ND . Please review to see if this would work for your application.
