3,000 parts per car model are expected to become obsolete each year


OVERCOMING OBSOLESCENCE


How working with the right chip designer can help manufacturers avoid the problem of discontinuation


T


he fact that thousands of parts per car model are expected to become obsolete each year


presents a huge challenge for automotive manufacturers. The automotive industry is more prone to obsolescence than other industries because of the sector’s unprecedented rate of development. In fact, consultancy company Oliver Wyman estimates that some 3,000 parts per car model are expected to become obsolete every year. Where vehicles were once entirely mechanical, there is now increasing digitalisation throughout including lane and hazard detection systems,

automatic parking and even completely autonomous driving — all requiring advanced electronics. The faster these developments occur, the quicker components become obsolete. Consultancy firm Roland Berger estimates that some 62 per cent of the automotive market relies on older, more specialised chips. And as chip manufacturers are moving to more advanced technologies, there’s a drop in availability of older components for OEMs. As a result, manufacturers are having to spend more time dealing with supply chain problems and sourcing suitable chip replacements. Often, obsolescence is managed


reactively, after the process or component is out of date. But this is expensive and leaves little room for error. Alternatives may be hard to find and replacement chips must be verified before use. In addition, there’s often significant redesign work required to ensure that a product is compatible with the substitute device. Even if a suitable chip doesn’t require product design changes, it’s unlikely to have the same performance or functionality as the original IC.
