CHIP ID 435 - Hex inverter burned, inputs ok outputs none

My composite signal stop working a few weeks ago and i traced the problem to the 435 chip
which is an open collector Hex inverter DM7406.
I don't have such a chip available so i was wondering if
i could use the 7404 which is a hex inverter and i have plenty of.

I replaced with another dm7406 but didn't fix the problem.
With a little search i found that the problem is the 47uH inductor next to COP.
Can i buy a new kind like this http://www.ebay.com/itm/Inductor-47uH-4 … XQS6pRwCwy?
