Use an experienced supply chain partner
if you partner with an experienced distributor, they can manage all these communications on your behalf, and will also be proactive in finding any updates, leaving you to focus on the manufacture and distribution of your products.
A reliable distributor will also be able to source the very best component alternatives for you, including hard to find components, meaning you will be in a good position when obsolescence happens.
While you may not be able to prevent component obsolescence, you can prepare for it by being proactive and aligning yourself with an experienced supply chain partner, like Rebound Electronics.
