You can try a retailer like Farnell (their catalogue has the codes for some parts), or manufacturers website/databooks. I've never seen anywhere you can look the part number up using the code. Can you narrow it done to whether it is a bjt, or fet or diode, or even two diodes? (I am assuming its in a SOT-23 package) Also, if you repeat the code here, someone may be able to find out for you.
