Top 5 Obsolete IGBTs to Buy Before 2026 — and Why
When legacy drives, elevator controllers, or industrial motor systems fail, downtime can quickly become costly — sometimes stretching from a few hours to weeks or even months if the right replacement parts aren’t on hand. IGBT modules are often the critical components that keep these systems running, but many popular modules are now obsolete or in short supply. Sourcing them at the last minute can mean long waits, inflated prices, and delayed repairs.
To help you avoid these costly disruptions, ATI Accurate Technology Inc. has identified five high-risk, high-value IGBTs that are in demand and running low on stock. Securing these modules now ensures your equipment stays operational, keeps maintenance teams on schedule, and prevents being caught off guard by lead time delays.

Industries Most Affected
These IGBTs are widely used across industries that rely on legacy drives, high-power motor control, and elevator systems:
- Elevator & Escalator Systems – Critical modules in legacy elevator drives; downtime affects commercial, residential, and industrial facilities.
- Industrial Automation & Manufacturing – Three-phase motor control in production lines, conveyor systems, and robotic automation.
- Renewable Energy / Solar & Wind Inverters – Modules support large-scale inverter and grid integration systems.
- Water & Wastewater Treatment Plants – VFDs in pumps and filtration systems depend on these legacy modules.
- Mining, Pulp & Paper, and Heavy Industry – High-current modules for material handling, hoists, and industrial motors.
Why Act Now
The market for legacy IGBTs has shifted dramatically. Many established modules are officially marked obsolete, and lead times for replacement components have grown unpredictably. Global semiconductor manufacturing is increasingly focused on new technologies, such as SiC and wide-bandgap devices, leaving traditional silicon IGBTs in short supply.
Economic factors are also driving cost pressures. International shipping costs, tariffs, and currency fluctuations make sourcing parts outside the U.S. increasingly expensive. Long lead times from overseas suppliers introduce uncertainty and delay, which can cascade into costly downtime for industrial systems, elevator fleets, and critical motor drives.
Availability in the U.S. is limited. Many legacy modules are no longer stocked domestically, and distributors that do maintain inventory often have minimal quantities. Sourcing from non-U.S. suppliers can require additional verification, import documentation, and customs processing — all of which increase operational risk.
ATI Accurate Technology Inc. maintains a strategic inventory of hard-to-find, end-of-life IGBTs in the United States. By sourcing these parts locally, customers can:
- Minimize downtime and maintain operational continuity
- Avoid unpredictable international lead times and cost fluctuations
- Ensure maintenance teams have access to the exact modules required for critical equipment
Acting now to purchase these high-risk IGBTs mitigates operational risk, protects budgets from rising costs, and ensures your systems stay running without interruption.
