[0-9] is the same as \d:

and * means 0 or more, which I'm not sure it's really what you need. If you
don't want to check for a specific number of digits but need 1 or more use =
+

/>\d+_\d+_\d+_F3/

If you want to limit to specific number of digits, you can use {a} to
specify a range of numbers (or range of numbers), or no quantifier it it's
exactly one occurence. For example:

/>\d_\d_\d{4}_F3/

which means, match >, then a digit, then _, then another digit, then anothe=
r
_, then 4 digits, then _F3
