Risk-Free Semiconductor Supply Chain Solutions fromRochester Electronics
Shortages, Lead Time Events, and Obsolescence
The evolution of semiconductor technology has followed predictable patterns over the last 50 years. Original component manufacturer (OCM) investments and resources are focused on the most profitable newer technologies, while costs are reallocated by discontinuing older products. However, many customers will still require long-term product support post-end-of-life (EOL). For the many professionals tasked with
maintaining products and systems with active and obsolete mission-critical components, building a reliable long-term supply chain, is crucial. Market shortages, long lead time events,
and component obsolescence are all real challenges businesses face. In our current market manufacturing companies have invested in producing products that remain incomplete while awaiting much-needed components. With investments frozen in these unfinished goods, sales, and available cash flow dip to uncomfortable levels. Manufacturers must ensure that a reliable
component source is in place, even after components become obsolete. This requires businesses to be resourceful in finding alternate component options during shortages and long lead time events, while strategically planning for obsolescence. Failure to do so could lead to serious challenges such as: • Line-down situations • Unnecessarily large financial commitments • Long-term component storage costs • Forced product redesign or requalification • Premature product EOL and reduced service life There is a common misconception that
when components are unavailable through the original manufacturer, unauthorised, or “grey market” sources are the only solution. Nothing could be further from the truth. The risk-free option of an authorised after-market supplier, such as Rochester Electronics, should always be the first choice, versus any purchase of products outside of the authorised channel. Rochester is 100% authorised by over 70
leading semiconductor manufacturers. Their factory direct, AS6496-compliant, offering negates the need for expensive redesign, requalification, and recertification. Components are 100% authorised, traceable, and guaranteed direct from the OCMs. As a result, Rochester can offer the original component warranties and guarantees.
A continuous supply source of both active components and EOL semiconductors Despite being traditionally known for EOL (end- of-life) products and solutions, today around one-third (5 billion devices) of Rochester’s in- stock inventory is active product. Over 10 billion of Rochester’s in-stock devices are classed as EOL by the original manufacturer. Rochester is well-positioned to offer a continuous source of supply during component shortages, and long lead time events, and to extend the life of applications beyond device availability. Rochester has over 15 billion devices in stock
encompassing 200,000-part numbers, providing the world’s most extensive range of EOL and broadest range of active semiconductors.
Concerned about date codes? - What is a safe shelf life for semiconductor components? Long-term storage represents a viable solution to the challenge of maintaining a continuous supply of semiconductor components in long- lifecycle applications, but how does long-term storage affect performance? OCMs (original component manufacturers)
continue to employ date codes as an indicator of when a component may be too old to perform its original specification. This is no longer accepted as an accurate signifier of quality and reliability. Virtually all components can be used well beyond this manufacturer- established date code. OCMs and traditional authorised distributors tend to store components for only a few years before turning over the inventory. However, Rochester Electronics has been successfully storing components for extended periods of time and bridging supply chain disruptions for long-life applications since 1981. When long-term component storage is a
requirement, it is important for customers to have confidence that properly stored components are reliable in the field. Rochester has conducted testing on the effects of long- term storage on solderability, mechanical integrity, and performance. They have published results in white papers and held webinars on the topic which also reference findings with similar results from Allegro and Texas Instruments. Independent tests confirmed that no negative
effects due to component aging were found to impact the solderability, mechanical integrity, and performance of components that have been properly stored for up to 17 years.

Continued Licensed Manufacturing Increasingly, Rochester is also able to offer ongoing manufacturing from known-good-die and test products according to the original test procedures. Rochester has produced over 20,000 device types ranging from new silicon all the way through assembly, test, and qualification. With over 12 billion die in stock, they have the capability to manufacture over 70,000 device types. Rochester licensed manufactured solutions
are current date code, sold with full approval under the original manufacturer’s part number, and is 100% compliant with the original datasheet specification. In some cases, Rochester’s manufactured solutions have extended the life of applications by 25 years from the original component manufacturer’s end-of-life date! They also offer a full range of
manufacturing services including Design, Wafer Processing, Assembly, Test, Reliability, and IP Archiving; providing single solutions through to full turnkey manufacturing, enabling faster time-to-market. As lead frame assembly types disappear from the market, Rochester is there with a continuation of solutions ensuring our customers do not have to do major redesigns to their system boards. To best support the customer’s ongoing
need to extend the life of semiconductor products, Rochester continues to invest in Design solutions, ensuring your system software does not need to change, while simultaneously creating drop-in hardware solutions that minimize new qualification expenses. Rochester specializes in the authorised porting of products from original fab processes but offers form/fit/functional replacements as well. Regardless of the Design solution from Rochester, no errata are introduced, and no system software changes are needed. When facing component shortages, long
lead time events, and critical component EOL for a long-life application, think Rochester Electronics; the experts in providing dependable and trusted “long-term” Semiconductor Lifecycle Solutions. Rochester keeps your business moving!
