Cross-reference check
Relationships and limits.
- The IPC lists one TP42001 pressure switch at Figure 32-40-20-15, item 160.
- The row prints the code GX but the supplied export does not define it.
- TP42000 is a separate pressure-switch record at Figure 32-40-20-10, item 125.
The supplied export does not define GX or state that TP42001 substitutes for TP42000. Keep the exact number and figure reference on the sourcing request.
