Can you help me to identify this part? GF499? No reference in the database

[ASanz.1]

I was looking at the database and I did not find this component. I would like to ask help to identify it because I believe that is a discontinued product and may be I am not looking in the right database. 

Can you help me? I attached the image:

I would like to provide more information. It is in the Projector Main Power Supply Fit for Optoma W341 X341 S341 near the optocouplers. I think that I am not understanding the ID.
