Obsolete Components in 2026: EOL Notices & Shortage Data

A record 621,909 electronic components were discontinued or declared obsolete in 2025 — roughly one-third more than in 2023 — according to lifecycle intelligence firm Z2Data. Even more alarming for buyers: 52% of those parts (323,286 components) reached end-of-life with no Product Change Notification (PCN) from the manufacturer at all.

If you manage a BOM in 2026, obsolescence is no longer an occasional annoyance — it is a structural feature of the market, colliding with the worst memory shortage since 2021 and the longest lead times in years. This page aggregates verified EOL notices issued by TI, NXP, Renesas, Infineon, onsemi, STMicroelectronics, Microchip and Cirrus Logic across 2025–2026, the key shortage statistics, the obsolete part numbers buyers are actually hunting for, and a practical response process. Every figure is sourced; full links are listed at the end.

The 2026 Obsolescence Picture in Numbers

• 621,909 components went EOL in 2025, up from roughly 470,000 in 2023 and second only to the COVID-era peak of over 750,000 in 2022, according to Z2Data.
• 52% of 2025 EOL events came with no PCN, and of the PCNs that were issued, only about 26% met JEDEC standards, according to Z2Data.
• Advanced semiconductors now move from introduction to EOL in as little as 2–5 years, and a single obsolescence-driven redesign costs between $20,000 and nearly $2 million, according to Z2Data.
• The squeeze is happening in a boom: global semiconductor sales hit a record $791.7 billion in 2025 (+25.6%), and Q1 2026 sales of $298.5 billion put the industry on track to cross $1 trillion this year, according to the Semiconductor Industry Association (SIA).

Major EOL Announcements, 2025–2026: Summary Table

The notices below were extracted directly from manufacturer PDN/EOL documents. Dates are the manufacturer's stated Last Time Buy (LTB) and last ship/delivery dates — most of these orders are non-cancellable, non-returnable (NCNR).

Two patterns stand out. First, the reasons are structural — "manufacturing support no longer available" (TI, Microchip), fab closure (Cirrus Logic), portfolio rationalization (Infineon, ST) — meaning these parts are not coming back. Second, several notices offer no replacement at all, which is exactly the scenario that pushes buyers into the open market.

Chip Shortage and Lead-Time Statistics, 2026

Obsolescence is hitting while the broader supply chain tightens dramatically. According to Tom's Hardware, data centers will consume about 70% of all memory chips made in 2026 — versus 20–30% in 2022 — while DRAM supply grows only 16% and NAND 17%, well below the historical 20–30% norm. According to TrendForce, 1Q26 conventional DRAM contract prices jumped a record 90–95% quarter-on-quarter (PC DRAM more than doubled; server DRAM rose about 90%), NAND rose 55–60%, and 2Q26 is forecast to add another 58–63% for DRAM and 70–75% for NAND, with meaningful new capacity not arriving until late 2027–2028.

Lead times confirm the strain. According to Baird's lead-time monitor (reported by Investing.com, April 2026), DDR5 and LPDDR5 DRAM both sit at 41 weeks — the highest in Baird's dataset — with Xilinx FPGAs at 40 weeks, Diodes Inc. parts at 37 weeks, MPS DC-DC converters at 33 weeks, and MOSFETs averaging 25 weeks. According to independent distributor J2 Sourcing, 14 semiconductor and passive suppliers announced price increases in April 2026 alone, ST MCU lead times stretched to 55 weeks, and SK Hynix has warned wafer tightness could persist to 2030 with a roughly 20% supply gap. ECIA's February 2026 Industry Pulse survey found only 5% of respondents reporting falling semiconductor lead times (2% for electromechanical parts), with some MCUs already past 20 weeks.

Pricing pressure extends across categories: according to TrendForce, Murata raised prices 15–35% on AI-server, automotive and RF MLCCs from April 1, 2026 (an NVIDIA VR200 NVL72 rack uses roughly 600,000 MLCCs, over 30% more than GB300), Samsung Electro-Mechanics weighed a double-digit MLCC hike, and ADI raised analog prices 10–30% (average ~15%) from February 2026 following TI's earlier 10–30% increase. The root cause is structural: according to TrendForce, AI memory (HBM + GDDR7) will absorb about 20% of global DRAM wafer capacity in 2026, and according to Tom's Hardware, each gigabyte of HBM consumes roughly 4× the wafer capacity of standard DRAM. According to IDC and Synopsys (via CNBC), the memory shortage will persist into 2027, pushing 2026 smartphone average prices up 14% to a record $523 while shipments fall 12.9% and the PC market contracts 11.3%.

For buyers of legacy parts, the most direct hit is DDR4: according to Assured Systems, Samsung stopped taking DDR4 orders in June 2025 with final shipments on December 10, 2025, and spot prices had already risen 50–100% by mid-2025 — making DDR4 the largest "just-discontinued, instantly scarce" category of 2026.

The Most-Requested Obsolete Part Numbers in 2026

Cross-referencing Findchips popular-search data (June 2026) with EOL records and community sourcing reports, these are the discontinued parts buyers ask for most:

The Counterfeit Trap in Obsolete Sourcing

Obsolete parts are where counterfeiters live. According to ERAI's 2024 data, suspect counterfeit and nonconforming part reports hit 1,055 — up 25% and a nine-year high. According to ERAI's 2025 annual report (via Astute Group), reports eased to 748, but 60.02% of reported counterfeits were obsolete parts, roughly 24% of suspect counterfeits passed purely electrical testing, and 23.37% of faked brands were newly targeted that year — including Raspberry Pi and Supermicro. Electrical test alone is not enough; decapsulation, X-ray and traceability checks matter most precisely on EOL parts.

What Buyers Should Do: A 5-Step EOL Response Process

• 1. Audit your BOM proactively. With 52% of EOL events carrying no PCN (Z2Data), waiting for notifications means discovering obsolescence after stock is gone. Review lifecycle status quarterly.
• 2. Act inside the LTB window. Size last-time-buy orders against remaining product life plus safety stock — and remember most LTB orders are NCNR.
• 3. Qualify the manufacturer's suggested alternate first (e.g., OPA828 for OPA627, CLRC66303HNK for MFRC522, AT45DB041E for AT45DB041D) — it is the cheapest path when one exists.
• 4. For parts past LTB, source only through channels with testing and traceability. The ERAI numbers above are the reason.
• 5. Get a quote on hard-to-find stock. Dasenic sources obsolete, EOL and shortage parts across a catalog of over one million part numbers — submit an RFQ with your MPN and quantity, and our sourcing team will respond with price, availability and date-code/traceability details.
