Quick Answer: What replaced 861681-B21?
Discontinued: 861681-B21 | Replacement: UM.IV6AA.A19
Why HEWLETT PACKARD ENTERPRISE Discontinued the 861681-B21
Based on the available research, there is no published manufacturer detail confirming why HEWLETT PACKARD ENTERPRISE is discontinuing 861681-B21. The current status is EOL IN PROGRESS, which means 861681-B21 is still available for purchase, but discontinuation has been announced. No official end-of-life date for 861681-B21 has been identified in the provided sources, and no reason for the phase-out has been verified.
What can be said with confidence is that HPE typically issues end-of-sale notices a few months before sales stop, followed by a period of ongoing support. However, the research provided does not include a product-specific announcement for 861681-B21 or a technical bulletin covering UM.IV6AA.A19 as its replacement. For IT buyers, that means procurement decisions around 861681-B21 should be made carefully: availability may continue in the short term, but forward planning should center on UM.IV6AA.A19 where possible.
Because no official product page, QuickSpecs entry, or support notice was found for 861681-B21 or UM.IV6AA.A19 in the supplied research, it is important not to assume a discontinuation cause such as platform refresh, component obsolescence, regional SKU consolidation, or lifecycle standardization. Those are common industry patterns, but they are not confirmed here. The most accurate position is simply that 861681-B21 is in an announced end-of-life transition and UM.IV6AA.A19 is the identified replacement part.
What's New in the UM.IV6AA.A19
Replacement status is confirmed, technical changes are not
The main verified update is the part-number transition from 861681-B21 to UM.IV6AA.A19. The research does not provide specific technical differences, revised specifications, compatibility notes, performance changes, licensing updates, or packaging details between 861681-B21 and UM.IV6AA.A19. If you are updating a bill of materials, the safest conclusion is that UM.IV6AA.A19 is the replacement ordering reference you should evaluate first.
No published specification delta in the provided sources
For many HPE transitions, buyers look for changes in generation, interface, capacity, supported platforms, warranty terms, or included accessories. In this case, none of those differences can be verified from the supplied information. There is no manufacturer-backed evidence in the research that UM.IV6AA.A19 adds or removes any feature relative to 861681-B21.
Procurement impact matters more than feature claims
Since verified technical differences are unavailable, the practical change for most teams is procurement-related. If your organization has historically ordered 861681-B21, you should expect that sourcing may become more difficult over time as the EOL process advances. Moving internal purchasing references, quote requests, and approval workflows toward UM.IV6AA.A19 can reduce delays and help avoid last-minute substitutions.
How to treat 861681-B21 and UM.IV6AA.A19 during planning
Use 861681-B21 as the legacy part number for installed-base reference, documentation history, and asset tracking. Use UM.IV6AA.A19 as the active replacement part number for new quotes and future procurement review. Until HPE publishes fuller documentation, buyers should validate compatibility directly against their environment before replacing 861681-B21 with UM.IV6AA.A19 in production orders.

Upgrade Checklist
- Identify current usage of 861681-B21. Review purchase history, installed assets, service records, and open projects that still reference 861681-B21.
- Update procurement records. Add UM.IV6AA.A19 to your ERP, purchasing system, and approved vendor lists as the replacement for 861681-B21.
- Verify compatibility before ordering. Because no technical delta is confirmed in the supplied research, validate fit, platform support, and any dependency requirements for UM.IV6AA.A19 against your environment.
- Revise internal documentation. Update BOMs, standards documents, quoting templates, and project plans so teams know that 861681-B21 is in EOL transition and UM.IV6AA.A19 is the successor part number.
- Check availability timing. Since 861681-B21 remains available for now, decide whether to purchase remaining stock for short-term needs or move directly to UM.IV6AA.A19 for future orders.
- Confirm support expectations. Review current support coverage and any HPE lifecycle notices available through your channels, especially if 861681-B21 is tied to maintenance or compliance requirements.
- Standardize new requests on UM.IV6AA.A19. For new deployments or refresh cycles, direct buyers and engineers to request UM.IV6AA.A19 rather than 861681-B21 to avoid sourcing friction later.
