How to use this mapping

If you were quoted any of the part numbers above, they correspond to this market.
OEM-qualified parts offer the highest vendor support assurance and typically cost more.
Original manufacturer parts often provide the best balance of cost and compatibility.
Compatible alternatives may reduce cost but should be verified against platform policies.

▶How to read OEM, Original, and Compatible

OEM parts carry vendor certification (and often firmware locks) — highest support assurance, highest price. Original parts are the underlying manufacturer's modules without OEM branding — usually the best balance of cost and compatibility. Compatible parts are third-party alternatives — lower cost, but verify against your platform's policies first.
