How do I assign a view to a panel node in drupal
If you are display the panel on a node then you need to add a variant of the node/%node page. In Drupal 7 you would


Edit the node_view (node/%node) page.
Press Clone to create a variant of your current page.
Under Selection rules add Node:type and select your new content type.
Ensure that the new variant is above your current variant, or add Selection rules to your current variant too.
In your new variant under Content replace the old View with the new View.


Note: If the only change to the View (and Page) is the Content type then you could have used the Content type of the node being viewed as a Contextual filter on the View. Then there would be no need for a Panel variant or another View.
