The best ways to manage component obsolescence

Manage component obsolescence strategically and plan it in to your design phase

Managing Component Obsolescence

The life-cycles of electronic components are shortening with the demand and specifications of semiconductors constantly changing, the lives of products within this market and becoming increasingly shorter.

Long term product availability is vital in industries that require a rigorous roll out process including testing, standards and certifications, these red tape industries require a reliable source of components and the technical expertise to support them with obsolescence.

Buyers and procurement specialists need to be able to manage component obsolescence strategically, otherwise they could be faced with:

• Production delays or line stops
• A large financial commitment tied up in last-time buys
• Long term storage costs
• Forced product redesign
• A premature product end of life

 GD Rectifiers works with customers to explore their component obsolescence options and details the best ways to manage component obsolescence in future:

Design phase considerations

Poor component selection can lead to premature product end of life resulting in a redesign and requalification. This can be a prevalent deciding factor for customers with long development and qualification cycles, and the lowest cost may not always be the most favourable. Buyers and procurement specialists should seek clarification from the suppliers on OCM commitments to long term availability before designing the components in to the build.

Understanding the total cost of obsolescence

It’s important to understand the cost and risks associated with obsolescence from the start. Component obsolescence shouldn’t just be a problem to be addressed as an after-thought it should form part of the initial decision-making process. The project plans should highlight any anticipated product redesigns and the costs associated with this.

Plan for obsolescence

Preventative planning for obsolescence can help manage expectations, costs, component engineering and purchasing management.

Monitor life-cycles

Buyers and procurement specialists should monitor component life-cycles with the help of distributors in order to anticipate problems before they occur.

PDNs

Work closely with your authorised distributors to receive PDNs (product discontinuation notices) so that you can forward plan how this will affect your product and the options available to you.

Last time buys

LTB orders are inevitable but a supplier with an end of life transition partner offers risk-free on-going stock and production if demand rises, redesigns are delayed or in-service commitments are extended. Liaise with your distributor on LTBs and develop a plan to fulfil the supply until the product redesign is scheduled.

Purchase from authorised channels

There is a misconception that once the original component manufacturer (OCM) stops making a component, that the only option is to source the product from the grey market or unauthorised channels. However, the zero-risk option of using an authorised distributor should always be the buyers only logical choice.

It’s also important to remember that original component manufacturers do not provide guarantees for products purchased through unauthorised channels.
