Why QNAP INC Discontinued the TS-H1683XU-RP-E2236-128G-US
QNAP INC lists TS-H1683XU-RP-E2236-128G-US as fully discontinued and no longer for sale. The product appears on QNAPWorks.com's End of Life Products page, which confirms the TS-H1683XU-RP-E2236-128G-US has reached end-of-life status and directs buyers to contact them for a replacement.
What is not confirmed is just as important for IT purchasing teams. QNAP has not publicly announced a specific end-of-life date for TS-H1683XU-RP-E2236-128G-US, and available sources do not give a formal reason for the discontinuation. There is no cited manufacturer statement tying the change to regulatory updates, platform redesign, supply chain constraints, or a new product generation.
For procurement and infrastructure planning, the practical takeaway is straightforward: TS-H1683XU-RP-E2236-128G-US is fully discontinued, no longer available for new purchase, and should be treated as an unavailable SKU in refresh planning. If your standards list still references TS-H1683XU-RP-E2236-128G-US, it is a good time to update that documentation and validate an alternative such as TS-H2287XU-RP-E2378-64G-US before the next buying cycle.
What's New in the TS-H2287XU-RP-E2378-64G-US
The main challenge when reviewing TS-H2287XU-RP-E2378-64G-US is that public source data is limited. Available research supports TS-H1683XU-RP-E2236-128G-US as discontinued, but it does not fully confirm TS-H2287XU-RP-E2378-64G-US as the official manufacturer-designated replacement. Still, TS-H2287XU-RP-E2378-64G-US is the replacement part number being referenced for buyers moving off TS-H1683XU-RP-E2236-128G-US, so the comparison below focuses on what can be verified.
Processor platform changes
TS-H1683XU-RP-E2236-128G-US uses an Intel Xeon E-2236 processor with 6 cores, a 3.4 GHz base clock, and burst speeds up to 4.8 GHz. Research tied to the replacement path points to an Intel Xeon E-2378 in the TS-H2287XU-RP-E2378-64G-US naming convention, with 8 cores and a 2.6 GHz clock. Based on those data points, TS-H2287XU-RP-E2378-64G-US may represent a move to a newer Xeon platform with more cores, though the public sources do not provide a complete official spec sheet for the exact queried model.
Memory configuration differences
One clear difference in the available research is memory. TS-H1683XU-RP-E2236-128G-US is identified with 128GB RAM, while the suggested replacement path associated with TS-H2287XU-RP-E2378-64G-US references 64GB RAM. For virtualization, deduplication, or memory-heavy storage workloads, that means buyers should not assume a like-for-like RAM starting point when replacing TS-H1683XU-RP-E2236-128G-US with TS-H2287XU-RP-E2378-64G-US.
Model and listing mismatch
Another important point is the mismatch in public listings. Research notes a B&H listing that suggests a similar upgrade path from TS-H1683XU-RP-E2236-128G-US to a unit with an Intel Xeon E-2378 and 64GB RAM, but that listing appears to mismatch the exact queried TS-H2287XU-RP-E2378-64G-US model. In other words, buyers should verify the exact chassis, bay count, and memory configuration before placing an order for TS-H2287XU-RP-E2378-64G-US.
What remains consistent in planning
TS-H1683XU-RP-E2236-128G-US is known as a 16-bay 3U rackmount NAS. Public research provided here does not fully document the same physical details for TS-H2287XU-RP-E2378-64G-US. Because of that, IT teams should confirm rack space, drive compatibility, networking requirements, and installed memory before treating TS-H2287XU-RP-E2378-64G-US as a direct drop-in replacement for TS-H1683XU-RP-E2236-128G-US.

Upgrade Checklist
- Confirm the target SKU. Verify that TS-H2287XU-RP-E2378-64G-US is the exact replacement you want quoted, since public listing data shows some model mismatch.
- Review CPU and RAM requirements. Compare your current TS-H1683XU-RP-E2236-128G-US workload against the replacement's 8-core Xeon E-2378 and 64GB memory profile.
- Check chassis and bay assumptions. Do not assume TS-H2287XU-RP-E2378-64G-US matches the 16-bay 3U layout of TS-H1683XU-RP-E2236-128G-US without validation.
- Validate application compatibility. Review any storage services, virtualization roles, or backup jobs currently running on TS-H1683XU-RP-E2236-128G-US.
- Plan data migration. Map out cutover timing, replication, backup integrity checks, and rollback options before retiring TS-H1683XU-RP-E2236-128G-US.
- Update internal procurement records. Replace TS-H1683XU-RP-E2236-128G-US in asset standards, BOMs, and lifecycle plans with the validated successor SKU.
- Get a current quote. Check availability and ordering details for TS-H2287XU-RP-E2378-64G-US before finalizing budget approvals.
Bottom Line
TS-H1683XU-RP-E2236-128G-US is fully discontinued and no longer available for purchase. TS-H2287XU-RP-E2378-64G-US is the replacement part number being used for buyers moving forward, but public source data does not fully confirm it as the official manufacturer-designated successor and leaves some specs unverified.
For most IT teams, the right approach is to treat TS-H2287XU-RP-E2378-64G-US as the next part to evaluate, while confirming memory, chassis, and exact configuration before issuing a PO. That extra validation step helps avoid mismatches when replacing TS-H1683XU-RP-E2236-128G-US in production environments.
