Diodes PCN-2822 EOL | 76 order codes, LTB expired; 43 codes have no LTB

Last Updated: November 5, 2026 | Last Verified: October 20, 2026 | Manufacturer Notification Date: May 5, 2026

According to Diodes Incorporated’s “PCN-2822 REV 1,” 76 discrete semiconductor part numbers are subject to end-of-life (EOL).Of these, 43 part numbers never had a Last Time Buy (LTB) opportunity, and the final order date for the remaining 33 part numbers—October 30, 2026—has already passed. The final shipment date is May 5, 2027, but this is subject to availability.

This notice is not a new announcement dated October 13. It is an update to an article originally published on October 20 for domestic procurement personnel—which reconfirmed the manufacturer’s notice dated May 5—to reflect the expiration of the final order deadline.

Points Confirmed via Primary Information from the Manufacturer

Notification Date: May 5, 2026 / Effective Date: November 5, 2026. Diodes states that products in Tables 1 and 3, for which no LTB is provided, may be discontinued without further notice. October 30 is not the end of the purchase guarantee period for all 76 part numbers.

Examples of affected complete order codes and manufacturer-recommended replacements

The table above shows representative examples. Please verify all order codes in Diodes’ official PCN-2822 REV 1. Recommended replacements do not unconditionally guarantee compatibility or suitability for mass production. The manufacturer itself also requires verification of the relevant data sheet.

Impact on Procurement: Facts and Outlook

Confirmed: 43 part numbers have never been eligible for LTB. The final order deadline of October 30, 2026, set for 33 part numbers has passed. The notation “LTB Available” in the table reflects the classification at the time of this notice and does not imply that additional orders are currently being accepted.The final shipment date is May 5, 2027, subject to availability. Recommended replacements have been listed for 22 part numbers.

Unconfirmed: This notice alone does not confirm domestic or overseas distribution inventory for individual part numbers, actual selling prices, remaining quantities of accepted orders or scheduled shipments, NCNR conditions, or future price increase rates. We have also not confirmed whether additional orders will be accepted after the deadline.

Potential Risks: If these part numbers remain in the BOMs of maintenance products or mass-produced printed circuit boards, redesign, component qualification, and customer approval may be required. We have not confirmed that specific part numbers are actually out of stock.

Actions to Be Taken by Purchasing, Materials, and SCM Personnel

1. Organize BOMs, AVLs, outstanding purchase orders, and maintenance applications, and cross-reference Table numbers using complete order codes that include the suffix.
2. Prioritize the 43 codes without LTBs, and confirm the remaining quantities of accepted orders, scheduled shipments, on-hand inventory, and distribution inventory with the manufacturer and authorized distributors.
3. For the 33 codes subject to LTB, verify in writing the quantities accepted within the deadline, remaining unshipped quantities, secured quantities, shipment schedules, and applicable conditions. Compare these with production and maintenance demand; for any shortfalls, do not assume an additional LTB will be issued, but instead verify remaining inventory and evaluate alternatives.
4. For alternative candidates, evaluate electrical characteristics, form factor and pin configuration, thermal characteristics, regulatory compliance and quality certifications, and customer approval to determine a specific switchover schedule.
5. For overseas channels, verify authenticity, lot numbers, date codes, traceability, storage conditions, and return policies.

The expiration of the final order deadline does not mean that shipments of distribution inventory or accepted orders have uniformly ceased. Since final shipments are limited to cases where supply is available, please manage orders that have been placed but for which acceptance, quantity confirmation, and shipment schedules have not yet been confirmed separately from quantities that have already been secured.

AI Components’ Practical Comments

Rather than focusing on the total number of 76 items, it is crucial to categorize them from the outset into 43 codes with no LTB and 33 codes for which the LTB has expired. Even though discrete components have low unit prices, a shortage of just one item could prevent product shipment.We recommend finalizing the complete order codes and required quantities, while simultaneously verifying accepted orders and remaining inventory and evaluating alternatives.Diodes’ PCN-2824 (LTB expires October 28, 2026) and PCN-2855 are covered in a separate notice. Please verify this to avoid confusion.

Consultation on Procuring EOL and Replacement Parts

When consulting with AI Components, please provide the manufacturer name, complete part number, required quantity, desired delivery date, target price, and whether a replacement is possible. Knowing the application, desired lot size, and required quality certifications will help us make a more informed decision. Availability, pricing, and delivery times will be provided on a case-by-case basis after verification and cannot be guaranteed in advance.
