Yeah, it's a little annoying how Newark seems to think "phono" and "phone" plugs are the same thing.
I made a similar order from them this week, except I got the 4 contact TRRS version:

I also saw this cheaper one at almost half the price which seemed very similar so I ordered it too for comparison:

The shipment arrived today and as far as I can tell the two jacks are physically identical in every way. Right down to the "EST" logo and the "JAPAN" marking. Pretty weird.
