New Revision: 5892

- bom/research/STATUS: removed Ralec RTA02-4D330JTP. It's already been 
  replaced, with the CTS 741X083330JP.
- bom/research/STATUS: moved parts with incompatible substitutes to separate
  section and categorized the incompatibilities

 "borderline availability" = only sources with lead time, although short. May
     become harder to source.
-"incompatible substitute" = differs in footprint, pin numbering, or physical
-    shape, but fulfills same function.
+- Footprint: Footprint changes
+- Mechanical: mechanical interfaces other than footprint and height change
+- Pins: pin assignment changes (but signals stay the same)
+- Circuit: surrounding circuit needs to change (except for traces)
+- Function: part performs only similar function, e.g., needs other connector,
+  software interface changes, etc.
 Parts without a file have not been researched yet.
