The tips are replaceable - you should have gotten a little package with a few of them and a tip puller. If you mean the whole thing, from Samsung, and possibly from any large retailer that carries Samsung phones, or your carrier can order one for you. (They probably run about $25.) Or from Amazon - http://www.amazon.com/s/ref=nb_sb_n...ag=hawk-future-20&ascsubtag=UUacUvbUpU4595372
Best Buy used to sell them. They label them for a 10 inch tablet but they work fine on the GNP 12.2. Mine works with my Note 4 phone too. They are about $25
Most Samsung parts come from China, that's reason it's always cheaper to buy from Chinese sellers on Ebay. I take this option for items that not in need right away, but most take only a week or 10 days to get delivered. Ebay is also my option to avoid paying tax, the same item if buying from Amazon + Tax.
