Engineering Selection Recommendations

The MN43LL4W01 serves as the primary substitute for the M2043LL4W01. Both parts share identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9065) and are manufactured by the same supplier. The critical distinction is product status: the M2043LL4W01 is obsolete, while the MN43LL4W01 maintains active status. For new designs, procurement activities, and long-term component planning, the MN43LL4W01 is the appropriate selection. Existing inventory of the M2043LL4W01 may be utilized for legacy system support where design constraints require the original part number.
