Compatible alternatives same JEDEC specification
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.

Frequently asked
Can I use a Micron or Samsung module instead?
In most servers, yes: MTA9ASF1G72PZ-2G3 (Micron), M393A1K43BB0-CRC (Samsung), HMA81GR7AFR8N-UH (SK hynix) match this module on every key specification (8 GB, DDR4-2400, RDIMM, 1Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What does 1Rx8 mean?
One rank of DRAM chips, each 8 bits wide ("×8"). Rank organization affects how many modules a memory controller can drive at full speed, so it's listed as a key spec.
