This ranking comes from our own enquiry log, not from page views. When the same part number arrives from several unrelated plants in the same month, it is usually one of two things: a component reaching the end of its service life across an installed base, or a system that has just gone out of manufacturer support.
Either way it is a signal worth acting on. Parts that trend here tend to get harder to find over the following quarters, and prices move with scarcity rather than with a list.
If something you run appears on this page, it is worth holding a spare now. Ask your account manager to review your installed base against this list — we do it free for existing customers.
