In this video I reveal the various life cycle states for components so you can avoid ones that are likely not to be available.
When looking through component data-sheets, or looking online you'll see a note about their position in the electronic component lifecycle: things like preliminary, active, not recommended for new designs and so forth. What do these lifecycle status or phases terms mean?
To try to avoid components going obsolete during the production of a product and not being available it's absolutely necessary to understand the various designations, terminology and the names given for these lifecycle stages or phases. This way you can avoid having too many components that become unobtainable during the life of your product.
The main component lifecycle stages or categories are:
1) Preliminary - when a component is still being developed and only initial information is available. Samples may be available but the final product could change.
2) Active - when the component has been launched and the design is stable. These components should be used in new designs.
3) NRND - this stands for Not Recommended for New Designs and it indicates the component is nearing the end of its production life.
4) LTB - Last Time Buy sometimes called obsolescent and this indicates that the final production run is being made for the component and it will not be available after this.
5) Obsolete - this is when the component is not longer produced and it is not available.
It is really important when designing a new circuit to ensure that the components have the best chance of being current or active when the design enters production and for as long as possible after that.
