OEM cross-references are compiled from distributor cross-reference data and OEM documentation. Verify against your vendor's parts list before ordering.
Fits these servers memory support by platform
Confirmed = listed in the vendor's memory documentation for that server. Vendor match = the vendor's own part cross-reference matches this module and its speed is validated for the platform; the module is not taken from that server's memory list. Spec match = this module meets the platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. Confirm against your server's qualified parts list before ordering.
Also marked as same part · spec-neutral suffix
These part numbers are the same module. The trailing suffix encodes the DRAM die-rev / on-DIMM sourcing, not the JEDEC spec.

Frequently asked
Is Dell 02TX5N the same module as MTA18ASF2G72AZ-2G3B1ZG?
Yes. Dell resells this Micron module under part number 02TX5N; Dell does the same as 99L0471-001.A00. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Samsung or SK hynix module instead?
In most servers, yes: M391A2K43BB1-CRC (Samsung), HMA82GU7AFR8N-UH (SK hynix) match this module on every key specification (16 GB, DDR4-2400, UDIMM, 2Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take MTA18ASF2G72AZ-2G3B1ZG?
Dell PowerEdge R240, Dell PowerEdge R340, Dell PowerEdge T140, Dell PowerEdge T340 match it through the vendor's own part cross-reference (e.g. Dell 02TX5N) with a validated speed. Other DDR4 UDIMM platforms generally accept it too; verify against the server's qualified parts list.
