IEC 62402:2019

Overview

IEC 62402:2019 is an international standard published by the International Electrotechnical Commission (IEC) focusing on obsolescence management. This standard provides comprehensive requirements and guidance for organizations that depend on external parties for the continued value and functionality of supplied items. The document outlines a cost-effective obsolescence management process applicable throughout all phases of an item's life cycle, helping organizations anticipate, mitigate, and resolve obsolescence risks related to electrical, electronic, and related technologies.

This second edition of IEC 62402 replaces the first edition from 2007 and advances the approach by establishing clear requirements rather than just guidelines. It expands the obsolescence management framework as a general process applicable to all technologies and items, making it a vital resource for businesses aiming to maintain long-term operational continuity and asset value.

Key Topics

IEC 62402:2019 covers critical aspects of obsolescence management including:

• Establishing an obsolescence management policy – Developing a formal policy to define objectives and governance.
• Infrastructure and organization – Setting up dedicated roles and responsibilities within the organization to manage obsolescence effectively.
• Obsolescence Management Plan (OMP) – Creating detailed plans that specify how obsolescence risks will be addressed across the item's lifecycle.
• Design strategies to minimize obsolescence – Incorporating proactive approaches such as modularity, open standards, and sustainable technologies during product design to extend utility.
• Obsolescence management approach – Using risk assessments, monitoring mechanisms, and decision-making processes to choose between proactive and reactive strategies.
• Resolution and implementation – Selecting appropriate resolution methods including life-of-need buys, substitute items, emulation, or redesign.
• Performance measurement and continuous improvement – Defining metrics to evaluate how well obsolescence activities meet organizational goals and identify opportunities for enhancement.

The standard also includes informative annexes that provide vocabulary, detailed resolution methods, risk assessment examples, and decision-making frameworks to aid practical application.

Applications

Implementing IEC 62402:2019 assists organizations in:

• Managing lifecycle risks for complex systems dependent on components and technologies that may become obsolete.
• Reducing maintenance and support costs by anticipating obsolescence and avoiding unplanned downtime or urgent redesigns.
• Enhancing product and system reliability by ensuring long-term availability of critical parts and technologies.
• Extending service life and optimizing total cost of ownership for electrical and electronic equipment across industries such as aerospace, defense, energy, manufacturing, and transportation.
• Strengthening supplier relationships and agreements by defining clear obligations and expectations related to obsolescence.
• Complying with international best practices to demonstrate due diligence in product support and lifecycle management.

By adopting this standard, organizations foster a structured obsolescence management culture that enables informed decision-making, proactive risk mitigation, and sustained value realization from technological assets.

Related Standards

IEC 62402 aligns and supports a broader ecosystem of international standards dedicated to lifecycle management, quality assurance, and risk assessment, including:

• IEC 61508 – Functional safety of electrical/electronic/programmable electronic safety-related systems.
• ISO 9001 – Quality management systems and continual improvement processes.
• ISO 55000 series – Asset management standards focusing on value realization and risk management.
• IEC 61511 – Safety instrumented systems for the process industry.
• IEC 62321 – Assessment of chemical substances in products, supporting sustainable technology choices.

Together, these standards provide a robust framework addressing operational excellence, safety, and sustainability, reinforcing the effective management of obsolescence within the global electrotechnical environment.
