US Digital Product Change Notifications (PCNs) are updated frequently, in keeping with our continuous improvement efforts and strategic supply management policies. Some PCNs communicate technical changes such as improvements in performance, durability, robustness or environmental compliance. Others pertain to external enhancements such as marking, color, materials, packaging, adaptability or aesthetics. PCNs are also issued when a particular product has reached its End-of-Life (EOL).

These notifications are part and parcel of our ongoing product lifecycle management program, and every effort is made to notify customers of changes in advance.

If you have questions about a particular model or configuration, please contact our customer support team at 1-800-736-0194 or support@usdigital.com.
