IEC TS 62686-2:2019 PDF

Overview

IEC TS 62686-2:2019 - Process management for avionics: Part 2 defines general requirements for passive components intended for aerospace, defence and high performance (ADHP) applications. It specifies minimum process, documentation and verification expectations for commercial off-the-shelf (COTS) passive devices (resistors, capacitors, inductors, etc.) when used within manufacturers’ published datasheet limits and used in conjunction with IEC TS 62239-1 (electronic component management). This Technical Specification replaces IEC PAS 62686-2 (2016) and is intended to guide OEMs, suppliers and procurement teams in selecting and managing passive components for high-reliability systems.

Key topics and technical requirements

• Scope and applicability: Applies to general-purpose COTS passive components for ADHP; does not alone guarantee ADHP suitability - OEMs may require redesign or additional testing as part of their ECMP.
• Traceability & documentation: Requirements for traceability, date codes, unit packaging, labels, moisture sensitivity level (MSL) marking and lead‑free identification.
• Product/Process Change Notification (PCN): Required notification practices and minimum content for changes affecting component suitability.
• Shipment and handling controls: Unit pack, intermediate packing, ESD protection and shipment procedures to preserve component integrity.
• Electrical & mechanical controls: Baseline electrical testing, device marking, termination finish management and MSL controls.
• Qualification & testing: Qualification methodology, test samples, maintenance of qualification records; guidance includes a broad set of environmental and reliability tests (temperature cycling, moisture resistance/biased humidity, high temperature operating life, vibration, shock, solderability, tin‑whisker assessment, board flex, etc.) (see Annex A).
• Quality management & audit capability: Internal quality audits, subcontractor controls, sampling plans, outgoing quality and failure analysis support.
• Product monitoring & reporting: In-line monitoring, problem notification and data reporting to support production control.
• Environmental Health & Safety (EHS): Device handling, materials/substance requirements and regulatory compliance expectations.

Applications and practical value

• Ensures consistent procurement and acceptance of COTS passive components for avionics, defence and other high-performance systems.
• Guides suppliers in implementing process controls, documentation and qualification needed by ADHP OEMs.
• Helps OEMs integrate COTS passive parts into their Electronic Component Management Plans (ECMPs) - reducing supply-chain risk, improving traceability and supporting obsolescence/product discontinuance strategies.
• Useful for engineers performing component selection, reliability assessment, incoming inspection, and non-conformance management.

Who should use this standard

• Avionics and defence OEMs, system integrators and design engineers
• Passive component manufacturers and contract manufacturers
• Procurement, quality and reliability professionals in ADHP and other high-reliability industries
• Certification and supply-chain managers requiring structured PCN, traceability and qualification documentation
