Key Takeaways

  • IC numbers are unique identifiers assigned to integrated circuits (ICs).

  • They provide traceability throughout the manufacturing, distribution, and field service processes.

  • IC numbers typically consist of three parts: the manufacturer’s code, the device type, and the production code.

  • Understanding IC numbers is essential for inventory management, repair, and troubleshooting.

  • Various standards and databases exist to help decode and register IC numbers.

    What is an IC Number?

    An IC number, also known as an integrated circuit (IC) number, is a unique identifier assigned to each individual IC. This number serves as a critical traceability mechanism throughout the IC’s lifecycle, from manufacturing to field service.

    Structure of an IC Number

    IC numbers are typically composed of three essential components:

    • Manufacturer’s Code: A unique identifier assigned to each IC manufacturer.

    • Device Type: A code that identifies the specific type of IC.

    • Production Code: A sequence of numbers or letters that denotes the production batch and other specific information.

      Purpose of IC Numbers

      IC numbers play a crucial role in various aspects of the IC industry:

      • Inventory Management: IC numbers simplify tracking and managing inventory levels.

      • Repair and Troubleshooting: By identifying the specific IC, repair technicians can quickly pinpoint the cause of a malfunction.

      • Field Service: IC numbers enable the identification and replacement of faulty ICs in the field.

      • Warranty Claims: IC numbers help manufacturers verify warranty claims by tracking the specific ICs that were sold.

      • Counterfeit Prevention: IC numbers assist in identifying counterfeit ICs, ensuring the integrity of electronic components.

        Decoding IC Numbers

        Decoding IC numbers is essential for accurate identification. The process involves using standardized databases maintained by organizations such as the International Standards Organization (IEC) and the Joint Electron Device Engineering Council (JEDEC). These databases provide cross-references between IC numbers and specific manufacturers, device types, and production information.

        International Standards for IC Numbers

        To ensure uniform interpretation of IC numbers, various international standards have been developed:

        • IEC 60062: Defines the general requirements for semiconductor devices, including the format and content of IC numbers.

        • JEDEC JESD37: Provides industry-specific guidance for IC numbers.

          Online Resources for IC Number Lookup

          Numerous online resources offer IC number lookup services:

          • ICDB: A comprehensive database maintained by the Microelectronics Industry Council.

          • Semiconductor Database: A database provided by the Taiwan Semiconductor Library.

          • PartMiner: A search engine that specializes in electronic component data.

            These resources provide access to detailed information on IC numbers, including manufacturer data, device specifications, and production history.

            IC Numbers in the Digital Age

            As the electronics industry continues to evolve, IC numbers are becoming increasingly important. With the proliferation of smart devices and the Internet of Things (IoT), the ability to trace and troubleshoot ICs is paramount. IC numbers serve as the essential link in connecting the physical and digital realms.


            IC numbers play a fundamental role in the electronics industry, providing unique identifiers that facilitate traceability, inventory management, repair, and troubleshooting. Understanding the structure and purpose of IC numbers empowers engineers, technicians, and end-users alike to effectively navigate the complex world of integrated circuits.
