Question:

What is the status of the WL50, WL51, MC50, and MC51 miniature microphones?  If discontinued, what are the replacements?

Answer:

As of February 2012, all versions of the WL50, WL51, MC50, and MC51 microphones are discontinued.

Replacement models are:
WL50B = MX150B/O-TQG
WL51B = MX150B/C-TQG
MC50B = MX150B/O-XLR
MC51B = MX150B/C-XLR

There are no replacements for tan (T) versions or white (W) versions of the WL50 or WL51. 
There is no replacement for the WL50BX unterminated cable version.
There is no direct replacement for the low sensitivity versions (LO) of the WL50. 

MX150/O is -46 dBV; WL50 is -45 dBV; WL50-LO is -54 dBV. 
MX150/C is -51dBV; WL51 is -50 dBV.

MX150 or MX153 can be used as a wired mic when paired with the preamp RK100PK.
