I great deal of the confustion going on is because you keep callng your iPad an iPad 2; both the old and the one you just ordered. iPad 2 referes to a specific model, the second model made; back in 2011 I think. There is no other iPad refered to as an iPad 2. None.
The iPad 2 had a 30 pin connector, a much heaftier build than any modle after the iPad 4, and wonāt run any iOS verison beyond iOS 9 (if memory serves). Nothing that fit the old iPad will fit a new one. There is that big a difference. If your current iPad is running iPadOS 13, then itās not an iPad 2. It might be an iPad Air 2. A very different beast.
The current iPad modle for sale (new from Apple) is a 7th generation iPad. It will sometimes be simply refered to as the new iPad. Anything you order for those will fit.
In another thread you tried to idenify your iPad using a part number. You ended up using the M series part nubers. These were not intended for public use, and so are difficult to pin down. A better part number is the A series part number. You can find this by going to Settings > General > About. Tap on the the Modle number to toggle between the M and A part numbers.
Find the model number of your iPhone, iPad, or iPod touch
If you are using an older iPad with an older version of iOS, then you might find the model number under Legal & Regulatory instead of About. Itā was a weird place to put it.
You can then see what your iPad model and features are here:
Identify your iPad model
Iām not trying to pick on you, and I hope I donāt come accross that way. Finding out and using the correct model for your iPad will help a lot when researching parts and asking questions here.
