Aerospace, Military & Defence Flight of longevity
Rochester explains how aerospace and defence buyers can be confident that critical components will remain available for long-life products and systems
A
erospace and defense markets have product lives that far exceed those of the components which go to make them. Long-term product availability
is vital in these sectors, and companies need to ensure that a reliable long-term source of components is available.
Companies not only need to establish a sourcing partner that can offer guarantees of availability over the long term but can also demonstrate a controlled transition process through end-of-life and into long- term fully authorised supply – or even long-term production.
As an AS6496-compliant distributor and licensed manufacturer, Rochester Electronics continues to offer Military Grade semiconductors and packages long after the original component manufacturers (OCMs) discontinue them. In addition to the millions of components available in-stock, Rochester’s in-house high-reliability hermetic assembly line offers a full complement of package styles including Ceramic DIP, Side Brazed DIP, Flat Pack, CQFP, PGA, Ceramic Leadless Chip Carrier, and Metal Can.
Rochester also offers a wide range of commercial and industrial components and can supply a custom flow built to meet the needs of source-controlled drawings.
Rochester’s extensive in-house qualification and test facilities ensure complete risk-free sourcing of components in compliance with industry standards. Rochester is a QML

Rochester built products are manufactured using known-good-die stored in one of its two nitrogen wafer storage facilities; and are tested to AS6496 standards using the original test processes employed by the OCM. Products retain their original part number because they are guaranteed to meet the original datasheet specification. As a 100 per cent authorised source of supply, anti-counterfeiting standards that apply to independent suppliers such as AS6171 and AS6081 are NOT required.
For ongoing critical obsolete component needs, where Rochester does not hold available inventory or wafer to build, Rochester can leverage its vast Test and Design Engineering experience to keep our customers’ systems going. Rochester can help with suitable alternatives (grades, speeds, finishes, packages) and the creation of additional testing parameters to provide the customer evidence needed to qualify the alternative. Rochester can also support fundamental design changes such as the replacement of obsolete key components with ASIC solutions. The possibility exists in these cases to transition to an ASIC which is not only identical in terms of fit-form-function, but with no software changes required and no errata. This means that Aerospace DO-254 re-qualifications, even for safety-critical (DAL-A) applications, can be greatly simplified as a minor change. Rochester Electronics offers the most comprehensive Stock – Build – Redesign service available for Military and Aerospace customers.
