You can try the following site, but I don't know if there is any way to tell if discontinuation is not currently planned for the item.
Information on discontinued products is now available on the Intel Product Change Notification (PCN) System.
To search for a discontinued product:
- Go to Intel Product Change Notification (PCN) System.
- Select "Key Characteristics" from the first drop down box.
- Select "Product Discontinuance" from the second drop down box.
- Click "Search".
Sorry about my last post. I just found the link but didn't realize that a login was required to view until I tried it. Anyway, all discontinuation notices for products are posted on Intel's site. You can do a search under the support section. If your item is not currently planned for end of life I don't think there is any way to know.
