Diodes PCN-2855 EOL | Order codes 845 and 298 have no LTB

Last Updated: October 9, 2026

Conclusion: Action Varies Depending on Whether Order Code 845 Is EOL or LTB

On October 6, 2026, Diodes Incorporated issued Product Change Notice (PCN) “PCN-2855 REV 1” regarding the discontinuation and consolidation of assembly and test lines. This notice covers a total of 845 part numbers for discrete and analog semiconductors.Of these, 298 part numbers do not have a Life Time Buy (LTB) opportunity. For the remaining 547 part numbers only, the last order date is February 6, 2027, and the last shipment date is June 6, 2027 (subject to availability).

Purchasing, materials, and SCM personnel should cross-reference the list not only with the base part numbers listed in BOMs and AVLs, but also with the complete order codes actually used for placing orders. It is risky to treat parts not subject to LTB as uniformly “available for purchase until February 6, 2027.”

Facts confirmed through primary information from the manufacturer

• PCN Number: PCN-2855 REV 1 / Notification Date: October 6, 2026 / Effective Date: February 6, 2027.
• Scope: End-of-life (EOL) due to the closure and consolidation of assembly and test lines for certain packages.
• Table 1: 293 part numbers, no recommended replacements, no LTB.
• Table 2: 512 codes, no recommended replacement, LTB available.
• Table 3: 5 codes, recommended replacements available, no LTB.
• Table 4: 35 part numbers, with recommended replacements and LTBs.
• Last Order Date for LTB-eligible items (Tables 2 and 4): February 6, 2027. Last Shipment Date: June 6, 2027 (subject to availability).
• The manufacturer has explicitly stated that items without LTB (Tables 1 and 3) may be discontinued without further notice.

Of the total 845 part numbers, 298 (293 + 5) are without LTB, and 547 (512 + 35) are with LTB. Manufacturer-recommended replacements are listed for 40 part numbers. For the remaining 805 part numbers, no recommended replacements are listed in the relevant PCN.

Specific Affected Order Codes and Recommended Alternatives

The above are representative examples. All codes are listed in Tables 1–4 of the official PDF. Even within the same series name, the applicable products may vary depending on the suffix, packaging type, and package.

Recommended alternatives do not constitute an unconditional guarantee of compatibility. The manufacturer’s PCN requires reference to the datasheet to determine compatibility. Please evaluate pinout, ratings, load transient characteristics, package, thermal conditions, and quality certifications under actual board conditions.

Impact on Procurement: Distinguishing Facts from Outlook

Confirmed Facts

No LTB opportunities are available for 298-series part numbers. For 547-series part numbers subject to LTB, final shipments will be limited to cases where supply is available. There are numerous order codes for which the manufacturer’s recommended alternatives are not listed.

Information Not Yet Verified

We have not confirmed the domestic and overseas distribution inventory, actual selling prices, confirmed delivery dates, order acceptance status, or future price increase rates for individual part numbers. While procurement difficulties following EOL are considered a general risk, this does not constitute a definitive determination of price increases or supply discontinuation dates for specific part numbers.

Actions Purchasing Personnel Should Take

1. Extract the BOM, AVL, and PO history for products using Diodes components using the full order codes, and cross-reference them with Tables 1–4 in PCN-2855.
2. Give top priority to Tables 1 and 3 (298 codes) with no LTB, and verify on-hand inventory, outstanding orders, the manufacturer’s acceptance status, and maintenance component requirements.
3. For Tables 2 and 4 (547 codes) with LTBs, calculate the required quantities based on production plans and the schedule for evaluating alternatives, and confirm the order terms with the manufacturer before February 6, 2027.
4. For codes with recommended alternatives, verify the ratings, dimensions, pin configurations, thermal, environmental, and quality requirements against the legacy part, and plan any necessary design changes and customer approvals.
5. PCNs require confirmation of receipt within 30 days of notification and, if evaluation samples are needed, a request for them within the same period. Manage the point of contact and response deadlines.
6. When preparing quotes and placing orders, confirm quantities, prices, guaranteed delivery dates, NCNR terms, and lot information in writing, and clearly identify any unconfirmed items as risks in the procurement plan.

AI Components’ Practical Comments

The practical focus of this PCN is not the total number of 845 codes, but rather identifying the 298 codes for which there is no final purchase opportunity.Even low-cost rectifier devices and power management ICs can become factors that halt the shipment or maintenance of equipment in which they are installed. We recommend first confirming the part numbers in use and the relevant tables, then conducting supply and demand verification and alternative evaluation in parallel. When sourcing from overseas, please verify the source, authenticity, lot history, and storage conditions.

Consultation on Procuring Diodes EOL Products and Alternatives

When contacting AI Components, please provide the manufacturer name, complete part number, required quantity, desired delivery date, target price, and whether a replacement is needed. We will evaluate procurement feasibility and potential alternatives on a case-by-case basis based on the application, required delivery date, and acceptable conditions. We cannot guarantee stock availability, pricing, or delivery times prior to conducting a search.
