Negative. Exact same part, been using both for 8 years :)

Cermet was all that was stocked originally in 1998 by Newark (Mouser did not
carry them until 2002), and it's lower drift (good for VCOs). If you notice, 149
pots have not been used in newer module designs :)
They are best used in the VCOs, though. But now I orer the factory 600pcs
minimum (gulp!), so I can get whatever I want (cermet or plastic, linear or log,
any value).
I did have to beg and plead to get Spectrol to make the 100ohm pots in the
WaveWarper (those puppies cost me $8.50ea!!, and I 'piggy-backed' a 100pc order
with a 500pcs 148 log pot order)
