"may discontinue a part and replace its applications with a new part number."

A mondatban a discontinue + a replace szavakat nem lehet különválasztani, mert ez a superseded jelentése. Replace nélkül nincs superseded parts. Itt nem csak discontinue-ról van szó, mert akkor jó lenne a már nem gyártott alkatrészek. Itt a replace-en van a hangsúly, tehát a kontinuitáson. Gyártják továbbra is, és jó a régi műszerekbe/gépekbe is.
Lehet, hogy dettó ugyanaz, csak mondjuk nem KU van a sorozatszámában, hanem FW, pl. azért más a gyártó. De a termék ugyanaz.

Question about superseded parts?
Sometimes a manufacturer may discontinue a part and replace its applications with a new part number. We refer to these instances as "Superseded Parts."

When a part is superseded to a new number, the old part number is no longer available (NLA), or discontinued. Occasionally, if the changeover is recent enough, the old part number may still be available due to lingering stock, but these instances are rare and the stock never lasts long.

Superseded parts will almost always carry a higher price on the new number, and often times there may be differences between the parts that could rended the new part unusable or undesirable on your vehicle.

We keep the old part numbers in our inventory database, and thus listed on our website, as a reference so individuals who have one of these old part numbers as the required item can quickly see what the new part is. Always keep in mind the 'SKU' is the part number you are ordering, NOT THE NUMBER IN THE PART DESCRIPTION.

There are several ways Superseded Parts are identified:

The part's description will have a number in it, different than the SKU (Such as 5551010AB in the description, where the SKU is 5551010AA)
There may be an 'SS' in the part description, followed by the new number (also will differ from the SKU)
On parts that are the superseding number, the description may say "Superseded Parts found" with a listing of the previous numbers
Some parts may have no information at all, or may just be listed as NLA (No Longer Available). In these instances a customer service rep can advise you on any replacing part numbers.

Maga a superseded is azt jelenti, hogy replace/take the place of (a person or thing previously in authority or use).

A válaszod (már nem gyártott alkatrészek) akkor lenne helyes, ha a kérdés az lett volna: discontinued parts (azaz no longer being sold).

A kettő nem ugyanaz.
