OK, can we take it as  8 characters after 2nd occurance of "_" is fixed?

if that is the case try

SUBSTRING(@[User::FileName], FINDSTRING(@[User::FileName], "_", 1) + 1, FINDSTRING(@[User::FileName],"_",2) - FINDSTRING(@[User::FileName],"_",1)+7)

is it always same format between 2nd and 3rd occurances of "_"?
if so try
SUBSTRING(@[User::FileName], FINDSTRING(@[User::FileName], "_", 1) + 1, FINDSTRING(@[User::FileName],"_",3) - FINDSTRING(@[User::FileName],"_",1)-7)
