Product development teams today face far more than just obsolete components. While EOL-End of Life parts often receive the most attention, manufacturers are increasingly affected by supply shortages, regulatory changes, lifecycle uncertainty, and sourcing risks that can disrupt production, delay product launches, and increase engineering costs.
For OEMs in Analytical Instruments, Industrial Automation, Manufacturing and Life Sciences, managing these risks requires continuous visibility across the entire Bill of Materials (BoM).
The iLenSys Obsolescence Manager (iOM) helps organizations identify, prioritize, and mitigate these risks through automated BoM analysis, risk prioritization, alternate part identification, change planning, and continuous monitoring. The platform evaluates risks such as EOL, LTB, NRND, Supply Chain, RoHS, and REACH, enabling engineering and procurement teams to act before problems impact production.
1. Obsolescence (EOL-End of Life)
Component obsolescence remains one of the biggest challenges for manufacturers.
When a manufacturer discontinues a component, OEMs often face:
- Production interruptions
- Product redesigns
- Emergency procurement
- Increased sourcing costs
- Missed customer commitments
Without early visibility, organizations are forced into reactive decision-making.
How iOM helps
- Detects obsolete components across the BoM
- Identifies affected assemblies and products
- Prioritizes risks based on business impact
- Suggests alternate components
- Tracks mitigation activities until closure
- Visual Dashboards provide a clear, simple view of key insights and metrics at a glance.
By identifying obsolescence early, engineering teams can plan redesigns instead of reacting to production crises.
2. NRND (Not Recommended for New Designs)
Many components remain available even after manufacturers classify them as Not Recommended for New Designs (NRND).
Although production continues, these parts are approaching the end of their commercial life and should no longer be selected for new products.
Ignoring NRND components often results in:
- Shorter product lifecycles
- Future redesign costs
- Increased engineering effort
- Repeat obsolescence issues
How iOM helps
- Automatically flags NRND components
- Highlights affected BoMs
- Supports proactive replacement planning
- Prevents new products from inheriting future risks
3. LTB (Last Time Buy)
A Last Time Buy (LTB) notification represents the final purchasing opportunity before a component is permanently discontinued.
Missing an LTB window can result in:
- Inability to manufacture products
- Expensive aftermarket sourcing
- Counterfeit component risks
- Emergency redesign projects
How iOM helps
- Detects LTB notifications during BoM analysis
- Prioritizes affected components
- Supports inventory planning
- Enables procurement teams to secure stock before deadlines
4. Supply Lead Time Risk
Even active components can become a production bottleneck when lead times suddenly increase.
Extended lead times may be caused by:
- Global supply chain disruptions
- Capacity shortages
- Geopolitical events
- Raw material constraints
The result is delayed production and uncertain delivery schedules.
How iOM helps
- Continuously monitors component availability
- Identifies long lead-time parts
- Highlights supply chain risks
- Supports alternate sourcing decisions
- Generates ongoing risk reports for proactive planning
Continuous monitoring helps organizations respond before shortages affect manufacturing.
5. Lifecycle Risk
Not every component has a clearly defined lifecycle status.
Some components have uncertain or changing lifecycle information, making it difficult to determine long-term availability.
Lifecycle uncertainty creates challenges such as:
- Poor design decisions
- Unexpected obsolescence
- Long-term support issues
- Reduced product sustainability
How iOM helps
- Evaluates component lifecycle information
- Identifies lifecycle uncertainty
- Highlights products requiring engineering review
- Supports lifecycle-based decision making
6. RoHS Compliance Risk
Many global markets require compliance with the Restriction of Hazardous Substances (RoHS) Directive.
Even if a component is commercially available, it may no longer satisfy the environmental requirements of target markets.
Non-compliant components can result in:
- Product certification delays
- Market restrictions
- Customer non-conformance
- Engineering rework
How iOM helps
- Detects and flags components impacted by RoHS exemptions
- Monitors exemption status and regulatory changes
- Enables proactive supplier engagement and future planning
- Accelerates compliant alternate part selection
- Reduces environmental compliance risk
Why Managing Risks Individually Is No Longer Enough
In reality, components rarely present a single risk.
A single electronic part may simultaneously be:
- NRND
- Approaching End-of-Life
- Experiencing long lead times
- Facing RoHS compliance concerns
Managing these risks independently creates fragmented processes and delayed decision-making.
iLenSys Obsolescence Manager evaluates multiple risks together, prioritizes them based on business impact, and provides a structured workflow for mitigation. The platform supports continuous BoM analysis, alternate part identification, risk resolution, change implementation, and ongoing monitoring to help engineering, procurement, quality, and compliance teams collaborate effectively.
A Smarter Approach to Obsolescence Management
Effective obsolescence management is no longer limited to tracking discontinued components. It requires continuous visibility into lifecycle status, sourcing challenges, supply chain disruptions, and regulatory compliance across the entire product lifecycle.
With the iLenSys Obsolescence Manager, organizations can:
- Analyze complete Bills of Materials for multiple risk types
- Identify EOL, NRND, LTB, lifecycle, supply chain, and RoHS risks
- Prioritize components based on business impact
- Identify qualified alternate parts
- Track mitigation activities
- Support engineering change planning
- Continuously monitor component health
By moving from reactive problem-solving to proactive risk management, OEMs can reduce redesign costs, improve production continuity, strengthen supply chain resilience, and accelerate time-to-market.
