The Hidden Power Behind Hydraulic Uptime | Obsolete IGBTs
Share
In a world obsessed with the latest tech, it’s easy to overlook the workhorses quietly powering industry behind the scenes. But if you're in the hydraulics space, you know one truth: legacy systems still dominate the plant floor, and when they fail, the fallout is real.
At the heart of many of these systems lies a component that doesn’t get much attention—until it’s suddenly unavailable: the IGBT (Insulated Gate Bipolar Transistor). And not just any IGBT. We're talking about the obsolete ones—models long out of production but still critical to your operation.
The Reality: Legacy Machines Aren’t Going Anywhere
Hydraulic systems are built to last. From heavy presses to industrial lifts, mobile equipment to power plants, these systems often run for decades. That kind of lifespan is great for ROI—but not so great when the drive module fails and you discover the IGBT inside hasn’t been manufactured since 2012.
These older systems depend on IGBT-based inverters and motor drives to regulate pump speed, manage torque, and reduce energy consumption. Without a compatible IGBT, you’re left with three options:
- Downtime, while you scramble for a replacement.
- Costly upgrades, which often trigger full system re-certifications.
- Or—if you're working with ATI—a fast, drop-in replacement from trusted obsolete inventory.
Why You Can’t Always Just “Use a Newer IGBT”
In theory, replacing an IGBT with a newer model sounds simple. But in practice, it’s rarely that easy.
Modern IGBTs often differ in:
- Pin layout and package type (making them physically incompatible)
- Voltage/current characteristics (impacting performance or reliability)
- Gate driver requirements (risking damage to surrounding circuitry)
Even if you can make it work, the engineering effort and testing time may outweigh the benefits.
That’s why many in the hydraulics industry are doubling down on preserving their existing systems—and sourcing discontinued IGBTs that offer exact fit and function.
Who’s Keeping These Systems Running?
The unsung heroes in all of this? Your MRO and engineering teams. These teams are under constant pressure to:
- Prevent unplanned downtime
- Extend asset life
- Control maintenance budgets
- Avoid triggering upgrades that require revalidation or retraining
At ATI, we partner with these professionals every day—helping them locate rare IGBT modules, interpret part codes, and plan proactive inventory strategies for aging equipment.
We stock and source thousands of obsolete parts from major brands like:
- Mitsubishi
- Fuji Electric
- Infineon
- Toshiba
- Semikron …and many others.
Planning Ahead: 2026 Is Closer Than You Think
More IGBT modules will reach End-of-Life (EOL) status in the next 12–18 months. If you're running hydraulics systems with aging drive tech, the time to prepare is now—not after a failure.
To help you stay ahead, we’ve created a free guide: “The Top 26 Parts to Buy Before 2026” – featuring critical IGBTs, drivers, and modules you should stock while supplies last. Download your free copy of our IGBT Resource Guide here: https://igbts.us/
Final Thought
Obsolete doesn’t mean irrelevant. In fact, when it comes to keeping legacy hydraulic systems running, obsolete IGBTs are some of the most valuable components on the market.
At Accurate Technology Inc., we’ve built our business around one mission: finding the parts others can’t—before downtime finds you.
