Infineon EOL 2026 | Automotive MOSFET 21: Final Order Deadline Has Passed—Replacements and Inventory Procurement

Last Updated: October 19, 2026

Update as of October 16, 2026: Inventory and Replacement Parts After the Final Order Deadline

According to Infineon Technologies’ product end-of-life notice “PD_297_25,” the final order deadline for the 21 affected part numbers was October 15, 2026. The affected products include automotive MOSFETs such as the AUIRF series.

The manufacturer’s stated final shipment date is April 15, 2027. This does not mean that new orders will be accepted until that date. Companies planning to continue using the affected products must confirm their existing order backlogs, distribution inventory, and transition to potential successor products.

We have not confirmed whether additional orders will be accepted after the deadline, whether the deadline will be extended, or the current level of distribution inventory. Below is a summary of the 21 order codes listed in the notice, their successor candidates, and the recommended actions after the deadline has passed.

Facts confirmed from primary sources

• Notice Number: PD_297_25. Date Issued: October 2, 2025. Reason: End of Product Life Cycle (EOL).
• Scope: 21 lines and 21 order codes listed in the notification table.
• Last Order Date: October 15, 2026. Last Delivery Date: April 15, 2027.
• The manufacturer has listed potential successor products. However, some have different packaging from the previous models.

Affected Order Codes and Manufacturer-Suggested Successor Candidates

The following lists the OPNs of the discontinued products and the successor candidates from the official notice. Recommended candidates do not guarantee drop-in compatibility. Please verify PCB mounting, electrical characteristics, and quality certifications on a case-by-case basis.

Important Note Regarding the Adoption of Replacement Candidates

The manufacturer’s designation “NEW (REPLACEMENT)” does not imply unconditional, complete compatibility. For example, the notice states that the replacement candidate for the discontinued part AUIRFS4115TRL (PG-TO263-3) is IAUTN15S6N025TATMA1 (PG-HDSOP-16),and the candidate for the discontinued part AUIRFS4010-7TRL (PG-TO263-7) is IAUT150N10S5N035ATMA1 (PG-HSOF-8). Since the package has changed, PCB modifications may be necessary.

Impact on Procurement: Distinguishing Facts from Outlook

Confirmed: The final order date of October 15, 2026, as stated in the manufacturer’s notification, has passed. The notification explicitly states that even orders placed before this date are subject to availability. Successor candidates have been proposed for the 21 affected part numbers.

Outlook and Unconfirmed Matters: EOL may necessitate securing maintenance inventory or design changes. However, we have not yet confirmed specific stockouts, price increases, domestic or overseas inventory levels, lead times, or orderable quantities.

Actions Purchasing, Materials, and SCM Personnel Should Take After the Deadline

1. Cross-reference the 21 order codes listed in the notice—including their suffixes—against mass production and maintenance BOMs, AVLs, and outstanding purchase orders.
2. Confirm with Infineon or an authorized distributor the acceptance status of existing open orders and the quantities still outstanding. If you wish to place additional orders after the deadline, inquire individually regarding the possibility of accepting exceptions and obtain written confirmation of the available order quantities, prices, NCNR terms, and guaranteed delivery dates. Do not assume that exceptions will be accepted.
3. Estimate the quantities required for production and maintenance through the final delivery date of April 15, 2027. This does not guarantee delivery of the full quantity by that date.
4. Evaluate candidate replacement parts based on their ratings, gate drive, thermal resistance, dimensions and pin configuration, automotive AEC-Q compliance, and any required customer approvals.
5. When considering overseas procurement, verify authenticity, origin, lot, traceability, and storage conditions.

Practical Comments from AI Components

Since the manufacturer’s published final order date has passed, it is important to first confirm the status of existing outstanding orders—including accepted and undelivered quantities—and determine whether individual arrangements can be made after the deadline. At the same time, please conduct a separate evaluation to determine whether the proposed successor candidates can be adopted for mass production as is.Particularly in automotive and industrial equipment, package changes can affect PCB mounting, heat dissipation, quality certification, and customer approval. Conduct investigations into the availability of the discontinued product and evaluate alternatives in parallel; do not incorporate unconfirmed supply into production plans.

Consultation on Infineon EOL Products, Overseas Sourcing, and Alternatives

When contacting AI Components, please provide the manufacturer name, complete part number (OPN), required quantity, desired delivery date, target price, and whether a replacement is acceptable. If you also provide the application (e.g., automotive/industrial equipment), required quality standards, necessary lot size, and acceptable conditions for a replacement, we will evaluate the procurement feasibility on a case-by-case basis.We cannot guarantee stock availability, pricing, or delivery dates until they have been confirmed.
