Nope, PNC is part number code, which is how they label their diagrams. That's the 61710. The actual part number is the MR or MB number. So you have everything right, 'cept that the US pn shoudln't have the 61710 on the end. 61710 is what both US and Japan use to ID the pic, which then breaks down to the part number. Sorry if I confused the issue. Good luck today!
