If you purchased the EDR after January 1, 2013, upgrade to the new 2011 EDR is free. Just download and install the 2011-EDR version and your existing key will be accepted.
If you purchased the EDR after January 1, 2007, upgrade to the new 2008 EDR is free. Just download and install the 2008-EDR version and your existing key will be accepted.
If you purchased the EDR before January 1, 2007 or are using a version pre-paid by Littelfuse, we offer a discounted upgrade.
If you have a free EDR (pre-2003), there is no upgrade and you must purchase the full EDR to become current.
How can I tell if I qualify for a discounted upgrade?
Your registration code can tell you. Click here for “Finding and Interpreting an EDR Registration Level”
Can I go back to the 2005 or 2008 version if I decide not to upgrade?
