To reiterate, your iPad5 is not compatible with Apple Pencil.

The only real alternative was manufactured by Adonit - but they have ceased production of Stylii that were compatible with older models of iPad.

The Adonit wasn’t a true alternative for Apple Pencil anyway - as it required specific support to be coded into third-party Apps.

Our resident expert on Stylus alternatives, MichelPM, will doubtless be along shortly to offer the benefit of his extensive knowledge of Apple compatible stylii.
