Rochester’s obsolescence solutions embrace a wide range of products
The diverse challenges facing five distinct product segments W
hen it comes to electronics, most designs will involve multiple semiconductor devices. With this point in mind, Rochester
Electronics’ goal is not to offer a single solution for an obsolete device, but instead provide a range of solutions covering the many mature devices likely found in designs.
For example, finding a solution for the main microprocessor won’t matter if there isn’t a solution for associated memory devices, or if stand-alone interface devices are no longer available due to newer processors having integrated the technology. Similar challenges exist throughout designs, including standard areas, such as analog, power, and timing. This can be even more challenging with application- specific peripherals, like highspeed networking, RF/wireless, and the many parallel and serial interface standards that exist.
Working with our suppliers and customers, and staying abreast of industry changes, Rochester continuously evaluates inventory to provide the best possible coverage for products with long lifecycle applications. These include finished goods inventory of active and obsolete lifecycle devices, and investment in wafer and die stock. Additionally, Rochester invests in test capabilities for continued manufacturing, and in die recreation for devices where the original die source is no longer available. For finished goods inventory, Rochester has over 10 billion units, covering 200,000- part number options. Product type and classification vary throughout the industry, but Rochester has grouped its inventory into five main categories: analog and mixed signal, processors and peripherals, logic devices, memory, and discrete. Each group faces its own challenges, regarding the likelihood of obsolescence and the availability of compatible replacements.

product types, that include power management, data converters, amplifiers, interface, audio- video, sensors, and RF-microwave. For many devices in this group, there are multi-source and potential alternative options, depending on the original design. However, many proprietary high-performance and specialty analog devices cannot be easily replaced and need to be monitored during their lifecycles.
Processor and peripherals
The processors and peripherals group are typically considered critical parts. Solutions cover 4-bit to 64-bit microprocessors and microcontrollers, that may use multi-sourced or proprietary architectures, and cover multiple product generations. There is also the added complexity of considering utilized software and tool chains.
Logic devices
Products in the logic group have evolved through the product generations resulting from technology advancements and supplier consolidations. Fortunately, compatibility exists across some product families. However, the more complex and higher density products

to monitor what remains available in the marketplace.
Discrete devices
have less compatibility and support for legacy voltage rails such as 5V and older package styles present definite challenges.
Memory and storage
The memory group benefits from a strong customer preference for using multi- sourced solutions. The challenge is due to a push to create faster, denser, and lower power memories, to keep pace with product advancements. As suppliers move to more modern memories, legacy options become limited, requiring consideration for alternatives. Alternatives, however, may differ in performance, density, temperature rating, and even package and power supply differences, all traits that may need to be considered. Also, existing proprietary specialty memories may have a limited number of sources. Once these drop out of the mainstream market it becomes critical
Lastly, the discrete group is the largest segment by volume. The general perception that there is relative “lifecycle safety” for discrete semiconductors, holds some truth, due to the amount of multi-sourcing and package compatibility, but it can never be held as a certainty. Like other semiconductors, there are constant advancements in improving efficiency and cost reduction. More recently, silicon carbide and gallium nitride technologies have gained traction in newer designs and may become a disruptive force to their silicon counterparts down the road. When confronted with the challenge of obsolescence, design requirements usually extend across various products. Rochester’s extensive finished goods inventory, licensed manufacturing solutions, and die recreation provide the widest possible coverage for critical long-lifecycle applications. No matter the product segment, Rochester is committed to supporting your needs. Find out more:
