Obsolescense Management
The parts supply chain is a complex puzzle. New semiconductor designs continued calls for low-power consumption and shorter life cycles are making supply chain management even more complicated.

The average component life cycle is now only 10 years.

With shrinking life cycles there is a growing sense of urgency for industry professionals. 94% of engineers say they feel greater time pressure and stress to solve problems even more efficiently and effectively than they did just three years ago.

Low-power consumption is accelerating obsolescence.

  • PLDs: For programmable-logic devices (PLDs), parts obsolescence is an increasing problem due to rapid innovation in lower-voltage components.
  • Microprocessors: Almost 2,500 new microprocessor part numbers introduced in 2014 had a nominal supply voltage of 1 volt or less.
  • FPGAs: Field-programmable gate arrays (FPGAs) are now typically below 2.6 volts, and fresh upstarts go as low as 0.85 volts.

The unfortunate result of the rising tide of obsolescence is a dramatic increase in counterfeit parts. As obsolescence grows, so does parts counterfeiting. “End-of Life”, “Not Recommended for New Design” and “Discontinued” parts make up 71% of the counterfeit reports since 2013. Counterfeit parts result in $7.5 billion in lost revenue, annually.

Obsolescence impacts everyone in the supply chain

  • Procurement Manager:Procurement has become more responsible over the years to ensure the overall success of a company’s supply chain.
  • Design Engineer:Design engineers play a critical role in minimizing the impact and costs of parts obsolescence during their product’s life.
  • Compliance Manager:Compliance managers must mitigate the heightened risk of counterfeits when parts succumb to obsolescence.
  • Component Engineer:Component engineers require access to timely, accurate and complete part data to respond to PCNs and EOL notifications.
