EN IEC 62435-8:2020
(Main)Electronic components - Long-term storage of electronic semiconductor devices - Part 8: Passive electronic devices
General Information
- Abstract
IEC 62435-8:2020 on long-term storage is applied to passive electronic devices in long-term storage that can be used as part of obsolescence mitigation strategy. Long-term storage refers to a duration that can be more than 12 months for product scheduled for storage. Storage typically begins when components are packed at the originating supplier where the pack date or date code are assigned to the product. It is the responsibility of the distributor and the customer to control and manage the aging inventory upon receipt of the dated product. Alternatively, a supplier-customer agreement can be established to manage the aging inventory. Philosophy, good working practice, and general means to facilitate the successful long-term storage of electronic components are also addressed.

Overview - EN IEC 62435-8:2020 (Long-term storage for passive electronic devices)
EN IEC 62435-8:2020 provides guidance and baseline requirements for the long‑term storage (LTS) of passive electronic devices as part of obsolescence mitigation strategies. The standard applies where storage durations can exceed 12 months and typically begins when components are packed and assigned a pack date or date code by the originating supplier. It covers the philosophy, good working practice, and general means to facilitate successful long‑term storage of passive components and clarifies responsibilities for suppliers, distributors and customers.
Key topics and technical requirements
The standard addresses practical storage controls and documentation, including:
- Storage considerations: overview of passive components and typical failure mechanisms in storage.
- Failure mechanisms and mitigation: identification of stimuli that drive degradation and recommended environmental controls to limit failures.
- Materials and storage media: guidance on appropriate packing materials and media for long-term protection.
- Moisture sensitivity designation: classification and handling of moisture‑sensitive devices.
- Dry packing and moisture barrier bags: requirements for dry packing, use of moisture barrier bags, and desiccants.
- Humidity indicator cards and dunnage: use of indicators and internal cushioning to protect components.
- Lot data, labelling and documentation: traceability via pack dates/date codes, lot records and labelling requirements for stored lots.
- Inventory management: inventory checks, dry packing refreshing, re‑assessment and options for supplier–customer agreements to manage aging inventory.
- Storage environment: sustained condition recommendations (temperature, humidity) and Annex A considerations for long‑term storage environments.
Practical applications - who uses this standard
EN IEC 62435-8 is intended for organizations that must preserve passive components for extended periods, including:
- OEMs, system integrators and aftermarket support teams (aerospace, railway, energy, defense)
- Procurement and obsolescence management teams performing lifetime buys
- Distributors, warehouses and long‑term storage service providers
- Quality, reliability and inventory managers responsible for traceability and lot control
Use cases include preventive storage to anticipate obsolescence, remedial storage when products are discontinued, and controlled storage to support long production runs or extended field support.
Related standards
Standards referenced and harmonized in the document include:
- IEC 60749-20 (mechanical/climatic test methods)
- IEC 61760-4 (classification, packaging and handling of moisture sensitive devices)
- JEDEC J-STD-075 (classification of non‑IC electronic components for assembly)
- Other parts of the IEC 62435 series (Parts 1–7) for broader LTS guidance
EN IEC 62435-8:2020 is a practical, standards‑based reference for implementing robust long‑term storage, minimizing degradation risks, and supporting effective obsolescence mitigation for passive electronic components.
