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.
