MC7330 hardware

We currently use MC7330 SKU#1102751 but having issues versus an older MC7330 that works with same firmware version. Are there hardware differences between difference types of MC7330? Also this modem is going EOL and received a notice that lists two type of MC7330 SKU#1102751 & 1103162. The firmware is the same. Is there a hardware difference between these two SKU#? Thanks for your help. JeffS
