Due to the signifi cant decrease in demand, Bourns is phasing out model TC73. The TC73 is an open-frame
trimming potentiometer with a carbon resistance element. The recommended replacement is model TC33.
The TC33 is manufactured with a cermet resistance element and offers tighter electrical and environmental
specifi cations.
Orders for Model TC73 will be accepted until March 1, 2010. Last ship date will be April 1, 2010.
Crosses to the replacement product are outlined below. Should your application require additional assistance,
please contact Bourns’ techweb (techweb@bourns.com).
