Can you please check the footprint for MMBT3904T?

Hello there,

Thanks for reaching us. The footprint for this part is a SOT-523F according to the datasheet, but we're going to double check it to ensure this content is correct. We'll get back to you once we have an update.

I understand, but if you see the description for the component that you guys used says that is a SOT-416 (first link) and this other datasheet for the same part says it as well (second link):

Thanks for your feedback. Indeed, the description is wrong for that part as it corresponds to an older specification from Fairchild Semiconductors.The SOT-416 according to the datasheet you sent should be named MMBT3904TT1G, which is available at the link below.
