With that kind of attitude i am reluctant to help...but here goes. Mouser has your transistor equivalent, see here [url]http://www.mouser.com/index.cfm?&handler=data.listcategory&D=*SSP4N90A*&terms=SSP4N90A&Ntt=*SSP4N90A*&Dk=1&Ns=SField&N=0&crc=true[/url]
or just search from http://www.mouser.com/

Good luck,
Robert
