Chip Rationing Is Back: Lead Times Past 52 Weeks and Buyers Pushed to 2028

For most of 2026 the component conversation has been about memory — how much DRAM costs this month, and who still has allocation. Reporting out of Germany this week suggests the problem is wider than that, and that for a growing list of parts the planning horizon has moved past a full year.

What the German supply chain is saying

Handelsblatt reported, and Taiwan’s Bureau of Foreign Trade reproduced for its own exporters, that customers of German component distributors are facing lead times of more than 52 weeks on some semiconductors, are receiving only partial quantities against their orders, and have watched some suppliers raise prices several times during 2026. The mechanism described is a familiar one: AI data-centre demand is absorbing fab capacity and engineering attention because that is where the margin is, and the parts left short are the ones that share the same lines or the same supply base — memory, power semiconductors, silicon-carbide devices and microcontrollers.

Two details are worth reading twice. Zollner Elektronik, a large German electronics manufacturing services provider, is quoted saying that memory chips are under strict rationing with heavily restricted supply. And Sensor-Technik Wiedemann says that Analog Devices and Texas Instruments have advised some customers to schedule orders into 2028. A Frankfurt broker quoted in the same piece is telling its customers to identify now which components will fall into a supply gap, and to buy next year’s requirement early.

The scarcity has moved into the substrate

The report also notes that tightness has spread beyond silicon into circuit boards and related materials, with individual product prices up by as much as 500 percent. Anyone who has tried to buy laminate or substrate capacity this half will recognise the pattern: the constraint is no longer only wafer starts, it is also the materials and process steps that turn a die into something you can ship.

Why this cycle behaves differently from 2021

In 2021 the shortage was demand-led and broad. Everyone ordered everything at once, and a wave of cancellations eventually cleaned it up. What buyers describe now is narrower and more structural. Capacity has been committed under long-term agreements to AI customers, memory makers have said publicly that more than three quarters of next year’s output is already spoken for, and a new fab needs several quarters after first production before it contributes meaningful volume. That combination leaves less downside elasticity: even if consumer demand softens, the tight parts stay tight, because they were never being made for consumer demand in the first place.

What a buyer should do about it

• Build a critical-parts list, not a shortage list. Rank what you buy by whether a substitute exists, how long qualification takes, and how many weeks of production a stock-out would stop. Twelve weeks of cover on a jellybean part is waste. Twelve weeks on a single-source microcontroller is not enough.
• Give your suppliers a forecast, not a series of orders. The manufacturers in that same report are asking customers for 12 to 18 months of demand visibility, which is the only input that lets a supplier hold allocation for you.
• Separate price risk from availability risk. In an allocation market the second one costs more. Accepting a documented price increase in exchange for a committed delivery slot is usually the better trade than shopping the spot market every month.
• Qualify the second source before you need it. Cross-referencing a pin-compatible alternative takes an afternoon on paper and months in a laboratory. Start now, on the parts that matter, and keep the data.
• Revisit the board, not just the bill of materials. If laminate lead times are stretching, the answer may be a stack-up that is easier to source, a smaller panel, or a panelisation that fits a standard size. That is a layout conversation, and it is cheapest to have before the tooling is cut.

Our position

We are a component supplier and contract manufacturer in Dongguan, which means we see both halves of this problem: what we can buy, and what our customers can build with it. When a part goes long we would rather tell you in week one than in week six. Our electronic component catalogue lists what we hold and source, including the passives, connectors, memory and power devices that sit on most of these designs, and our PCB and PCBA capability list covers the board side of the same question. If you want a straight answer on availability for a specific line item, send the list through our inquiry form and we will tell you what is real and what is not.
