Quick Answer: What replaced TK522Y?
Discontinued: TK522Y | Replacement: TK522Y
Why KYOCERA Discontinued the TK522Y
Based on current distributor research, KYOCERA TK522Y is in EOL in progress status, not fully end-of-life. OEM TK522Y toner cartridges are still available from multiple sellers, while some listings specifically for compatible versions show discontinued status. At this time, there is no published manufacturer notice confirming a final discontinuation date for TK522Y, and no official KYOCERA replacement part number has been announced.
That distinction matters for procurement teams. In practical terms, TK522Y can still be sourced as an OEM consumable, but the market is showing early EOL signals. Some distributors continue to show stock or same-day shipping for TK522Y, while others have cleaned up catalog listings for non-OEM or compatible alternatives. Because no formal KYOCERA timeline is available, buyers should treat TK522Y as a part that remains orderable today but may become harder to source consistently over time.
It is also important to clarify a common point of confusion: TK522Y is not replaced by a new KYOCERA part number in the available sources. If a catalog, ERP, or distributor feed shows TK522Y as replaced by TK522Y, that is not a true supersession. It is the same part number. For IT asset managers and print supply buyers, this means there is currently no technical migration from TK522Y to a different OEM SKU.
What's New in the TK522Y
No new part number for TK522Y
The main finding is that there is no officially announced replacement for TK522Y. The discontinued part and the listed replacement are both TK522Y, so there is no actual change in SKU, no refreshed OEM identifier, and no confirmed successor model from KYOCERA in the available research.
No technical change between TK522Y and TK522Y
There are no key technical differences because TK522Y and TK522Y are identical. Available sources describe the same yellow toner cartridge, the same stated 4,000-page yield, and the same use case for the FS-C5015N. For buyers managing standardized printer fleets, that means no expected change in fit, function, or performance based on the information currently available.
EOL status is the real update
If there is any meaningful update around TK522Y, it is the product lifecycle status rather than a product redesign. TK522Y is in EOL progress, with OEM stock still on the market. For procurement planning, this is the issue to watch. The part itself has not changed, but availability patterns may shift as distribution channels tighten and remaining inventory fluctuates.
Compatible listings may create confusion
Some distributors appear to mark compatible versions of TK522Y as discontinued, even while OEM TK522Y remains available. This can create mixed signals in search results and purchasing systems. If your organization requires original manufacturer toner, confirm that the quoted item is OEM KYOCERA TK522Y rather than a third-party compatible listing that may have a different lifecycle status.

Upgrade Checklist
- Verify the exact SKU. Confirm your purchasing record shows TK522Y and not a compatible alternative with a similar description.
- Check OEM vs. compatible status. Because some compatible TK522Y listings are marked discontinued, make sure quotes specify OEM KYOCERA if that is your standard.
- Validate printer compatibility. Available research identifies TK522Y as the yellow toner for FS-C5015N. Match this against your installed base before ordering.
- Review current stock strategy. Since TK522Y is in EOL progress, consider whether you need to buy extra units now to avoid later sourcing gaps.
- Do not assume a new replacement exists. There is no confirmed KYOCERA successor part number for TK522Y in the available sources.
- Update internal item notes. In ERP or procurement systems, add a note that TK522Y remains available but is in EOL progress with no announced replacement.
- Ask suppliers about live availability. Distributor stock for TK522Y may vary, so confirm lead time at the time of purchase.
- Standardize naming in catalogs. If your team sees TK522Y listed as both discontinued and available, separate OEM TK522Y from compatible listings to reduce ordering errors.
Bottom Line
KYOCERA TK522Y is best understood as an EOL-in-progress toner cartridge that is still available in OEM form, not as a fully discontinued item with a new successor. There is no official replacement part number announced, and the listed replacement TK522Y is the same TK522Y with no identified technical differences.
For most buyers, the right next step is not a product migration but a sourcing review. If TK522Y is part of your active print supply plan, it makes sense to confirm OEM availability and maintain clear internal records while the part remains orderable.
