Reports of Micron GDDR7 16Gb EOL | Impact on Procurement of MT68A512M32DF-28/32

Last Updated: September 25, 2026

Regarding Micron Technology’s 16Gb (2GB) GDDR7, multiple semiconductor and hardware media outlets have reported that the 28Gb/s model “MT68A512M32DF-28:A” and the 32Gb/s model “MT68A512M32DF-32:A” have been marked as End of Life (EOL) in Micron’s product catalog, according to reports from multiple semiconductor and hardware media outlets.

However, as of September 25, 2026, based on AI Components’ findings, no official notification from Micron regarding these two part numbers—including a specific PCN (Product Change Notification), LTB (Last Time Buy) deadline, or final shipment date—has been confirmed.Therefore, this article will treat the “reports of the EOL designation” and the “lack of confirmed official LTB terms” as separate issues.

Confirmed Facts

• Micron’s official GDDR7 Product Brief lists a 16Gb GDDR7 configuration as 512M × 32, 1.2V, and 266-ball FBGA, and confirms a part number structure with data rates of 28 Gb/s and 32 Gb/s.
• The affected part numbers are “MT68A512M32DF-28:A” and “MT68A512M32DF-32:A.”
• From September 23 to 24, 2026, several industry media outlets reported that both part numbers were marked as End of Life (EOL) in Micron’s product catalog.
• As of our verification, the individual product page for “MT68A512M32DF-28:A” on Micron’s official website displays “No results found” instead of specification information.
• However, we were unable to identify the specific PCN, LTB expiration dates, or Last Shipment Dates for these two part numbers during this verification.

Summary of Affected Part Numbers

Important: “EOL designation” is not synonymous with “immediate discontinuation of supply.” Distribution inventory, existing contracts, and final order conditions must be confirmed separately.

Impact on Procurement

The greatest impact will be felt by companies that directly specify “MT68A512M32DF-28:A” or “MT68A512M32DF-32:A” in their mass-production BOMs or AVLs.GDDR7 is used in applications requiring high-bandwidth memory, such as GPUs, image processing, high-performance computing, and AI-related devices.

Based on this information alone, it is not possible to conclusively determine that there will be a general shortage of GDDR7 or a sharp rise in prices. However, if the number of suppliers for specific capacities and speeds decreases, procurement options may become more limited for projects that continue to use the same specifications over the long term.

Furthermore, even if other companies’ 16Gb GDDR7 products or Micron’s products with different capacities are available, they may not necessarily serve as simple drop-in replacements. It is necessary to evaluate them comprehensively, taking into account capacity, data rate, package type, signal conditions, PCB design, and even the qualification requirements on the GPU and controller sides.

Actions Purchasing Personnel Should Take

1. Verify
   the BOM and AVL using the full part number—not just “Micron GDDR7”—but the complete part number, including the suffix, to confirm whether the product is in use.
2. Verify via Written Confirmation with Micron or Authorized Sales Channels Confirm the
   product status, order availability, LTB, last shipment date, and whether a successor candidate exists.
3. Calculate Required Quantities in Advance Calculate the required quantities based on
   current inventory, outstanding orders, monthly usage, product lifespan, and maintenance period.
4. Begin
   evaluating alternatives early. When considering products from other manufacturers or products with different capacities, involve not only the purchasing department but also the design and quality departments in the evaluation.
5. Prioritize
   traceability for overseas inventory. It is important to verify the date code, lot number, manufacturer’s label, packaging, storage conditions, and origin, and to avoid purchasing large quantities of unverified inventory based solely on EOL information.

Practical Comments from AI Components

The key point here is not to “immediately purchase market inventory upon seeing EOL information.” First, verify whether the affected part number exists in your company’s BOM; only then should you obtain official lifecycle information from the manufacturer or authorized channels.

In particular, for industrial equipment with long mass-production lifespans or products subject to maintenance obligations, waiting until an official LTB notice is issued may leave insufficient time to evaluate alternatives and secure the necessary quantities. If you are using the affected part number, it is practical to proceed in parallel with verifying authorized channels, calculating required quantities, evaluating alternative candidates, and investigating overseas inventory.

Please note that we will update this article if we receive official information from Micron regarding individual PCNs, LTB deadlines, and final shipment dates for this matter.

Consultation on Procuring Micron GDDR7 and EOL Products

If you require procurement or alternative sourcing assistance for Micron GDDR7, EOL memory, or GPU memory, please provide AI Components with the manufacturer name, complete model number (MPN), required quantity, desired delivery date, target price, and whether a replacement is feasible.

We will verify potential domestic and international suppliers, overseas inventory, substitution feasibility, and traceability requirements on a case-by-case basis. Information regarding inventory, pricing, and lead times will be provided based on verified data.

Frequently Asked Questions

Does this mean Micron’s 16Gb GDDR7 is no longer available for purchase?

We cannot definitively state that at this time. While an EOL announcement has been reported, we need to separately verify remaining distribution inventory, existing contract quantities, and final order terms. Please check with authorized sales channels using the full part number.

Can it be directly replaced with 24Gb (3GB) GDDR7?

Since the capacities differ, it is safer not to consider this a simple replacement. You must verify the memory configuration, board design, GPU/controller compatibility, and certification requirements with your design department.

What should I check when securing inventory from overseas?

Please verify the complete part number, quantity, date code, lot number, manufacturer’s label, packaging condition, storage conditions, and traceability. For EOL products, verifying the source is even more critical than for standard products.
