What Procurement Teams Need to Know
For procurement teams in electronics manufacturing, being notified that a component is now End of Life (EOL) brings a range of challenges to the business. This notification impacts the entire production cycle.
Not just components
Most of the time, EOL notifications are about a component or a product, but not always. Materials can be withdrawn by manufacturers for various reasons:
- Withdrawing a particular grade, perhaps because production requirements have fallen
- New regulations may mean a material no longer conforms
- Minimum Order Quantities (MOQ) can be made higher that renders that material unfeasible
Cost and availability
Availability tightens as everyone reacts to secure remaining supplies of that specific component, with distributors frequently adjusting pricing upwards (scarcity drives up prices). Your procurement team needs to move quickly to acquire stock, but without overbuying or being lured into purchasing from unreliable sources.
Margin pressure
As components go EOL and unit prices escalate, pressure increases on profit margins. In high volume production where margins may be tight, this can trigger difficult conversations about consumer pricing and even the viability of the product in the long run.
Coordinating Engineering, Manufacturing and Supply Chain
Conversations begin in earnest with other departments, starting with engineering and design.
- Do suitable replacement components exist?
- What impact does any specification variation have on the product?
Assuming these questions can be answered satisfactorily, Manufacturing will be asking about component availability. When can sample stock be acquired to test? When will stock be available for production?
Managing Supplier Relationships Strategically
Suppliers’ behaviour during EOL cycles varies widely. Some give early warnings (we liaise with clients as soon as we’re aware of EOL issues), share accurate forecasts and offer structured last time buy opportunities. Others provide minimal visibility or short notice. This is a real test on the relationship between procurement and suppliers.
As the UK Partner for Sunon, we work closely with them, working within their policy of continuous improvement. Whilst some clients will build one-offs (perhaps redesigned each year), many will want the same Sunon component for the lifetime of that product. We work with Sunon to meet these needs for our clients. Their product evolution policy looks like this:
- Roadmap published for next series alternatives, including sample stages, certification and volume production
- New series released for volume production in-tandem with existing range
- EOL notifications issued once next gen manufacturing has stabilised, with ~12 month window before LTB (Last Time Buy)
- LTB’s can be issued to Gelec, where deliveries can be scheduled over an agreed period (max. 12 months)
This gives existing clients about 30 months to test and approve alternatives. If you need a few Sunon fans for testing, see what is in our Sunon Shop.
Navigating the Grey Market and Quality Concerns
If an EOL notice is unexpected, the Grey Market may beckon. For every premium component brand, there exists plenty of “me too” brands and even some counterfeiters. If you have to deal with the grey market, this will be a real test of your due diligence processes, testing capabilities and governance.
Forecasting and Last Time Buy Decisions
First reactions may be to simply buy up as much stock as you can, prolonging the need for replacements or redesigns. Doing this will tie up capital and may cause storage issues, and could lead to write offs. Not buying enough may force you onto the Grey Market or the company into unscheduled redesigns.
Coordinating with Sales, Finance and Product Management about the product’s remaining lifecycle and what is therefore needed will minimise the chance of expensive mistakes.
Regulatory and Certification Awareness
Component changes may trigger recertification; engineers don’t want to have to re-evaluate parts due to EOL issues. Re-opening UL files can be costly. Procurement must ensure that all necessary documentation is complete and traceable. There will be pressure to source compliant alternatives that remove the need for regular recertification caused by inconsistent sourcing.
Spares & Repairs
Warranty commitments and brand reputation commits the business to long term product support. Spare parts need to be available long after production ends.
Neglecting this area can cause late lifecycle supply issues that damage customer trust.
Building a Proactive Obsolescence Strategy
The most successful procurement teams treat EOL management as a continuous process rather than a reactive one. This includes:
- monitoring lifecycle alerts
- maintaining strong relationships with component manufacturers, and
- using tools that predict obsolescence risk.
Working closely with Engineering and with suppliers to choose components with long availability and multiple sourcing options reduces future exposure. For organisations with large or complex product ranges, formal obsolescence management frameworks can dramatically improve resilience.
