Playstation 4 hdmi encoder ic

Hi. Just wanted to ask I bought a playstation 4 with a dead encoder ic with the part number: pansonic mn86471a 422p603g, but when I look online for a replacement the first 8 numbers and words match but the last 8 don’t. Just wondering does all the numbers and letters after match or is it just the first 8 example: mn86471a, as I can’t seem to find a exact match anywhere.

The first 8 should be all that matter. The second set are usually things like batch numbers and plant id that sort of thing

Thank you that’s helped alot.
