Where Can I get the information of EOL or NRND or for how many years it will be manufactured for components here on Digikey? is there any other option?

Each component listing has a Product Status field with that information.

If your goal is to only locate parts that are Active you can simply select that option only for the Product Status field on a search page.

DigiKey only has current Production Status available on the website, we don’t currently have forecasting/product lifecycle capabilities.
