Transistor Cross-Reference Database?

Does anyone know of a database that would allow me to enter the specifications of a transistor and have it show me a list of transistors that are matches or near matches (other than NTE)?

Everything I found is vendor specific and its a pain in the *ss to find anything that way.

transistor datasheet

this site has many datasheets and cross reference. may be this will help u
www.datasheetarchive.com
www.alldatasheet.com
www.datasheetcatalog.com

both RS components and Farnell components have a parametric search for semiconductor components
