Brab, let me try to explain (hope you don't mind :D)
All Panasonic Commercial 42" ED, 42" HD and 50" HD come with BNC Connectors
(as you mentioned the "Y" stands for BNC - "Z" for RCA ).
There's no version with RCA Connectors Available for the above Commercial Models (newer/older).
The 37" ED was the only exception with RCA Connectors on both Consumer and Commercial.
However, on 2003 Panasonic decided to include BNC Connectors also on the 37" Commercial TH-37PWD6(UY) . And there's no version available with RCA Connectors anymore for 37".
Don't know about future models.
So the TH-37PWD6UZ really doesn't exist.
Hope it helps. :)
