[TechAssist] Re: RCA ITC222 need part number

IHVT pn 259296 is drawing number 1075648000
IHVT pn 265409 is drawing number 1079963000

A note about drawing numbers, from a Thomson Newsletter, Dec. 22 2005:
-----------insert---------

Thomson products use instrument and chassis numbers to identify 
differences between products.  A similar number, called the drawing 
number, is used to identify differences between modules and components. 
  The drawing number can be found in PartsFinder II or ESI by entering 
the RCA-Parts (stock) number, then looking at the column called 
"Drawing".   The drawing number is typically (especially for television 
product) an 8 digit alpha-numeric sequence but may be longer. 
Generally, if the number is longer use the first 8 digits for comparison.
In most cases, the last digit in the 8 digit alpha-numeric drawing 
number designates a minor revision of the component or module that is 
typically forward and backward compatible and may be ignored.  The first 
7 digits should match exactly.  For example, if ordering a 265409 IHVT 
for an ITC222 chassis, the drawing number is 10799630.  If the drawing 
number on the IHVT label is 1079963A or 1079963B, etc., the IHVT is the 
proper replacement part.  However, if the drawing number on the label is 
10756480, the two components are not the same part.
Modules provide the same details but in slightly different form.  Using 
the same chassis, the SSB replacement module is a 265434 with a drawing 
number of 10889940.  Typically, modules have a bar code label that 
shortens the drawing number to a 6 digit alpha-numeric number and allows 
space for an 18 digit date code.  The psuedo-code for this module would 
read SSB-940.  As long as the psuedo-code reads SSB-940, SSB-94A, 
SSB94B, etc. it is the correct replacement.  If the psuedo code read 
SSB-720, it would not be the correct replacement for this chassis.
Before replacing any module, component or part that has a visible 
drawing number on an attached label, always check the drawing number on 
the label against the drawing number given for the part in either 
PartFinder II or ESI to assure the correct replacement
