Quick Answer: What replaced ADD-CAT6USBULK1K-YW?
Discontinued: ADD-CAT6USBULK1K-YW | Replacement: ADD-CAT6BULK1K-YW
Why ADD-ON Discontinued the ADD-CAT6USBULK1K-YW
Current research does not provide a confirmed manufacturer explanation for the discontinuation status of ADD-CAT6USBULK1K-YW. The available data shows ADD-CAT6USBULK1K-YW is still listed for sale, which indicates availability remains, but there is no official ADD-ON notice that confirms whether the part is fully discontinued or only in an end-of-life transition. For that reason, the most accurate status for ADD-CAT6USBULK1K-YW is EOL in progress, with availability continuing while channel inventory lasts.
It is also important to note that no public source in the research confirms why ADD-CAT6USBULK1K-YW would be retired, and no announced EOL date has been published. For IT buyers, that means planning should be based on procurement risk rather than on a fixed manufacturer timeline. If your standards list still references ADD-CAT6USBULK1K-YW, this is a good time to review whether ADD-CAT6BULK1K-YW should be used as the current purchasing part number.
Because official discontinuation details are limited, procurement teams should treat ADD-CAT6USBULK1K-YW as a part that may become harder to source over time. Where possible, update quotes, internal catalogs, and deployment documentation to account for ADD-CAT6BULK1K-YW while verifying fit for your specific installation requirements.
What's New in the ADD-CAT6BULK1K-YW
Replacement part number alignment
The main confirmed change is the shift from ADD-CAT6USBULK1K-YW to ADD-CAT6BULK1K-YW as the replacement part number used for current sourcing. While research does not confirm an official ADD-ON announcement naming ADD-CAT6BULK1K-YW as the manufacturer-designated successor, it is the replacement part identified for purchasing and lifecycle planning in this update.
Limited published comparison data
Research does not provide enough technical detail to document specific design changes between ADD-CAT6USBULK1K-YW and ADD-CAT6BULK1K-YW. The only basic product information available for ADD-CAT6USBULK1K-YW describes it as a 1000ft non-terminated yellow unshielded twisted pair PVC copper Cat6 U-UTP cable. No equivalent detailed specification set was available in the research for ADD-CAT6BULK1K-YW, so a feature-by-feature technical comparison cannot be confirmed from public data.
What buyers should assume cautiously
For practical purchasing purposes, buyers often want to know whether ADD-CAT6BULK1K-YW is a direct replacement for ADD-CAT6USBULK1K-YW. Based on the available research, that cannot be guaranteed at the specification level. The safer approach is to validate any required attributes before ordering, including cable category, shielding type, jacket material, conductor material, color, reel length, and compliance needs for the intended environment.
Availability and sourcing impact
The most meaningful difference today may be lifecycle position rather than a confirmed technical change. ADD-CAT6USBULK1K-YW appears to remain available, but with discontinuation concerns and no published timeline. ADD-CAT6BULK1K-YW should therefore be treated as the active sourcing target when you want to reduce future supply risk for new installs, expansions, or standardized stock purchases.

Upgrade Checklist
- Review all open quotes, approved vendor lists, and ERP records that reference ADD-CAT6USBULK1K-YW.
- Add ADD-CAT6BULK1K-YW to your internal item master as the preferred sourcing part number.
- Verify required specifications before substitution, especially if your project depends on exact cable construction or compliance characteristics.
- Confirm whether any customer contracts, bid documents, or site standards explicitly call for ADD-CAT6USBULK1K-YW by part number.
- If continuity matters, purchase remaining stock of ADD-CAT6USBULK1K-YW for existing rollouts while transitioning new deployments to ADD-CAT6BULK1K-YW.
- Document that no official public EOL date for ADD-CAT6USBULK1K-YW was available at the time of review.
- Ask your reseller to confirm current availability and any newly published details for ADD-CAT6BULK1K-YW before placing volume orders.
For network infrastructure teams, the main migration task is administrative as much as technical. Since public information is limited, moving from ADD-CAT6USBULK1K-YW to ADD-CAT6BULK1K-YW should include a simple validation step in your procurement process. That is especially relevant for larger rollouts where yellow Cat6 bulk cable may be standardized for patching rooms, horizontal runs, or inventory consistency across sites.
If your environment requires exact material matching, avoid assuming that ADD-CAT6BULK1K-YW is identical to ADD-CAT6USBULK1K-YW without checking current product documentation. The research supports awareness of a part-number transition, but not a fully documented technical equivalency statement. In practical terms, ADD-CAT6USBULK1K-YW remains relevant for support and stock checks, while ADD-CAT6BULK1K-YW is the part number to prioritize for future sourcing.
Bottom Line
ADD-CAT6USBULK1K-YW is best treated as an ADD-ON part in EOL transition: still available, but with discontinuation concerns and no published end date. ADD-CAT6BULK1K-YW is the replacement part number to use for updated purchasing, even though public research does not confirm detailed technical differences or an official manufacturer replacement notice.
If you currently buy ADD-CAT6USBULK1K-YW, now is the right time to review ADD-CAT6BULK1K-YW, update internal records, and confirm current specifications before large orders. This approach reduces sourcing risk while keeping procurement aligned with the latest available part-number guidance.
