The Last-Time-Buy (LTB)

The most typical response to an End-of-Life notice is to place a large “Last-Time-Buy” (LTB) order. While this may seem like the safest choice at first glance, for products with long lifecycles, relying on an LTB can be merely a short-term solution that introduces significant long-term risks.

Relying solely on an LTB is a risky strategy that can significantly affect profitability. It locks up substantial amounts of capital in inventory that may remain unsold for years. This situation poses a threat to the Cost of Goods

Sold (COGS) and can lead to margin erosion, which product directors strive to avoid. In addition to the initial cash outlay, it’s essential to consider the Total Cost of Ownership for that inventory, which includes:

High Carrying Costs: Properly storing electronic components, especially moisture-sensitive ones, requires specialized facilities with controlled temperature and humidity. This adds operational overhead and complexity.
Risk of Degradation: Components are not inert. Over years of storage, leads can oxidize, and internal materials may degrade, resulting in quality issues and potential failures in the field.
Forecasting Inaccuracy: Predicting demand accurately for 5, 7, or even 10 years ahead is nearly impossible. Over-purchasing can lead to significant losses from unsold inventory, while under-purchasing can result in facing an end-of-life crisis again, but this time without the option for last-time buys.

Proactive Sourcing for Long-Term Continuity

The LTB date does not signify the end of a component’s availability; it simply marks the end of its availability through the Original Component Manufacturer. This is where a specialist in Obsolescence Management becomes an invaluable asset. As a leading independent distributor, Suntsu utilizes exceptional global sourcing capabilities to locate EOL components on the open market for years after they have been officially discontinued.

This involves more than just searching online marketplaces; it includes a vetted global network of suppliers and a rigorous quality assurance process to mitigate the risk of counterfeit parts. Every component we source undergoes a multi-point inspection process that includes:

Documentation & Packaging Inspection: Verifying part numbers, lot codes, country of origin, and proper ESD/MSL packaging.
Detailed Visual & Dimensional Inspection: Examining the component under high magnification for evidence of remarking, resurfacing, or physical defects.
Advanced Testing: Utilizing tools like X-Ray analysis, solderability testing, and decapsulation to verify authenticity and quality.

This commitment to quality guarantees that the parts you receive adhere to the same reliability standards as the original, enabling you to maintain production with confidence even after the LTB has ended.

When a Replacement is the Only Path Forward

In some situations, the original component may become completely unobtainable. This is a scenario that engineers dread, as it often signals the beginning of a costly and time-consuming board redesign. However, it doesn’t necessarily have to.

Suntsu’s Component Engineering services are specifically designed to prevent this issue. Our goal is to find a replacement that perfectly matches in “form, fit, and function”:

Form: The physical dimensions, pin layout, and package type are identical, requiring no changes to the PCB layout.
Fit: The component integrates seamlessly into the existing manufacturing and assembly process.
Function: All critical electrical characteristics, performance parameters, and tolerances match the original part, ensuring the final product operates exactly as designed.

Our engineers will review your Bill of Materials (BOM) to identify possible replacements and provide the necessary technical data for your team to validate the new part. This can include services such as our Board Characterization, which confirms performance in your live environment. For unique requirements where a direct replacement is not available, we can also develop Custom Components, offering an elegant solution that eliminates the need for a complete redesign.

Building a Resilient Supply Chain

Successfully managing one End of Life (EOL) notice is a good achievement. However, developing a supply chain strategy that anticipates and mitigates these notices is even better. This shift enables you to transition from being a reactive problem-solver to a strategic leader. Building this resilience necessitates a partnership that extends beyond simply fulfilling orders.

By proactively engaging with Suntsu, you can access valuable market intelligence that informs your initial design decisions. Our BOM Analysis

services help identify high-risk components in your design before they reach their end-of-life (EOL). This allows you to explore alternative options at your convenience, rather than being dictated by the manufacturer’s timeline.

FAQs

How can I proactively manage component lifecycles to get ahead of EOL notices?

You can get ahead of EOL notices by shifting from a reactive to a proactive strategy. We partner with your team to perform a comprehensive BOM Analysis, where we analyze your Bill of Materials to identify high-risk components that are aging or have a history of supply volatility. By flagging these parts early—often during the design phase—we can help you qualify alternative components on your own schedule, not a manufacturer’s. This proactive Obsolescence Management is the key to building a truly resilient supply chain.

Is sourcing an EOL component from the open market more expensive?

The price of an EOL component on the global market is driven by supply and demand. While some high-demand parts can be more expensive, others are comparable to their original price. However, the most important calculation is the total cost of the alternative: a board redesign. The cost of sourcing an obsolete component is almost always significantly lower than the thousands of dollars in engineering hours, re-testing, and production downtime that a redesign requires. We focus on finding the most cost-effective solution to ensure your project’s continuity and profitability.

What’s the timeframe for sourcing a hard-to-find EOL component vs. a replacement?

The timeframe depends on the specific part and solution. Sourcing an existing EOL component can often be very fast—sometimes within days or a few weeks—if the part is available within our trusted global network. Finding and validating a replacement is a more involved Component Engineering project. This requires detailed analysis by our engineers, sourcing samples, and then validation and testing on your end. While it takes longer, it’s the right solution for ensuring the long-term health of your product when the original part is truly gone.

What are the risks of using a component in my design after it goes EOL?

Continuing to use an EOL component without a long-term strategy introduces significant risks to your product and business:

Supply Uncertainty: You become completely dependent on a shrinking global supply. If another company buys up the remaining stock, your production line could come to a sudden halt with no warning.
Lack of Manufacturer Support: The OCM provides no warranty, technical support, or failure analysis for EOL parts. If you encounter an issue, you’re entirely on your own.
Inability to Scale Production: Your ability to increase production is capped by the number of components you can find. This can prevent you from meeting unexpected customer demand.
Future Repair & Service Issues: Servicing or repairing products in the field becomes nearly impossible if you can’t source replacement parts for them.

What information does my engineering team need to start sourcing or replacement?

To get started as quickly and efficiently as possible, the most helpful information you can provide is:

The full Manufacturer Part Number
The Manufacturer’s Name
The Quantity you need
Any available Datasheets for the component

With this information, our sourcing specialists can immediately begin searching the global market, or our engineering team can start a detailed analysis to find a suitable replacement.
