The TDA1521 is not available at both of the largest electronics parts distributors in north America. Is it obsolete?
It may be obsolete but still can be found on eBay.
Indeed NXP TDA1521 is obsolete with no cross available. Take a look at Mouser Parts: 511-TDA2009A and 863-LA4625-E to see if they will work for the application. Mouser.com
