In 2025, end-of-life (EOL) risk for electronic components has become one of the biggest challenges for the supply chain. According to industry data, more than 328,000 EOL notices were issued globally in 2023, and this number is expected to continue to rise in 2025 (driven by AI/automotive demand pushing suppliers to optimize their product lines). EOL can lead to production disruptions, skyrocketing redesign costs (averaging $100,000-$500,000 per project), and even product withdrawal from the market.
This article, originally written by the supply chain expert team at AMPLE CHIP LIMITED , helps electronics engineers and OEM/ODM purchasing personnel proactively manage risks. Through strategies such as reusing surplus inventory, you can reduce costs by 20-40%, extend product lifecycles, and avoid the risk of counterfeit parts.

The chart above shows the typical lifecycle curve of an electronic component (from introduction to end-of-life/EOL).

Above: Schematic diagram of component lifecycle stages
1. Current Status and Causes of EOL Risks (Latest Insights as of 2025)
- Statistics show that in 2025, there will be an increase in EOL (End of Service) notices, with older logic ICs (such as the 74HC series), 8-bit MCUs (such as the PIC16), and analog devices (such as the ADXL335 accelerometer) frequently entering the EOL stage.
- Main causes :
- Technological iteration: Suppliers are focusing on new AI/automotive-grade products and abandoning mature, low-profit parts.
- Supply chain adjustments: Geopolitical risks and cost pressures lead to "immediate production stoppages" (no traditional LTB opportunities).
- Shifting market demand: The conflict between the short lifecycle of consumer electronics and the long lifecycle of industrial/automotive products.
- Risk impact : End-of-life (EOL) of single-source parts can lead to production line shutdowns; the risk of counterfeit parts increases (the black market proliferates after EOL).

Core steps :
- Monitor PCN/PDN : Subscribe to manufacturer notifications ( tools such as Microchip/ SiliconExpert ).
- Lifecycle assessment : Using databases to predict end-of-life (EOL) risk.
- Risk classification : High (single source/critical), Medium (multiple sources), Low (standard parts).
- Mitigation strategy options : LTB, substitution, inventory buffer, redesign.
- Implementation and Tracking : BOM Update + Supplier Audit.

Recommended practice :
- Regular (quarterly) audit of BOM: mark NRND/EOL parts.
- Use tools to automatically trigger alerts ( SiliconExpert , Z2Data).
- Prioritize new, unused remaining inventory: reliable quality and complete compliance certifications.
5. Recommended Tools and Platforms for 2025
- Free/Low Cost : Octopart (market data), Manufacturer PCN subscription.
- Specialty : SiliconExpert (Lifecycle Prediction).
- Platform Solution : AmpleChip – AI BOM Matching + Remaining Inventory Priority Recommendation + Sustainable Reporting.
Conclusions and Calls to Action
EOL (End-of-Life) risks are unavoidable, but proactive management can turn them into advantages: cost optimization + supply chain resilience. By 2025, excess inventory will become the mainstream mitigation solution.
