Is there an equivalent to this 40673?

I have also got an unused MPF102 but I would rather use the 40673 if it
is at all possible.

TIA,

Walford electronics are offering the MEF201 as similar to the 40673, the obsolete BF981 is probably electrically similar (look in older VHF TV tuners) or the BF991 if you don't mind fiddling about soldering wires to a SMD part.
