Fits these servers 18 of 111 platforms
Spec match covers every DDR4 RDIMM platform we track, so the spec-match rows above are a sample across vendors: 93 further platforms also match this module on spec. A server missing from this table is not a compatibility limit. Browse all servers →
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.

Modules match on all key specifications (type, form factor, capacity, speed, rank organization) and are generally interchangeable in servers that accept this spec. Interchangeability is based on matching JEDEC specifications, not per-server testing. Confirm against your server vendor's qualified parts list. View the full family →
Frequently asked
Is HPE P06031R-B21 the same module as M393A2K43DB3-CWE?
Yes. HPE resells this Samsung module under part number P06031R-B21; HPE does the same as P11443-091, HPE does the same as L47722-001. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Kingston or Micron module instead?
In most servers, yes: KSM32RD8/16HDR (Kingston), KSM32RD8/16MRR (Kingston), MTA18ASF2G72PDZ-3G2 (Micron) match this module on every key specification (16 GB, DDR4-3200, RDIMM, 2Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take M393A2K43DB3-CWE?
HPE Apollo 6500 Gen10 Plus (XL675d), HPE ProLiant DL345 Gen10 Plus, HPE ProLiant DL360 Gen10 Plus, HPE ProLiant DL365 Gen10 Plus, among others, match it through the vendor's own part cross-reference (e.g. HPE P06031R-B21) with a validated speed. Other DDR4 RDIMM platforms generally accept it too; verify against the server's qualified parts list.
