Given the design by Ti and the publications Ti released that I noted at the next link, I don't expect this part to last any longer than the first unless you take some clues from the documents I shared and see if you can bring down the heat a little.

Can you supply me with the part number for the replacemnet DLP chip in a Samsung 50" DLP LED TV (model # HLT5089SX/XAA ). I'm having the white / black dot issue on the screen, and need to replace the faulty chip.
Also can you tell me if the replacement chip is expected to last any longer than the original chip? This would determine if I fix the TV, or invest in a new one that would last longer than 3 years.
