Hi Jonathan,
I was just doing some research and noticed that although helpful '''++jayeff++''' linked the port for the Fire HD 10 5th gen / 2015 model which has this P/N ++SR87CV++ . You have '''SL056ZE''' for the 7th gen / 2017 HD 10 and you need this '''[https://www.ebay.com/itm/163420068232|USB port.]''' Might be other sellers cheaper but with 100% buyer satisfaction on a listing and over 100 sold there must be a reason. Like he said above there are TONs of various USB ports even in the micro B type. 5, 7 & 11 pins (I’ve even seen 6 on a few odd Samsung models). Middle mount, reverse mount, short, long, through hold, SMT, top or bottom mount, flange and no flange and the list goes on. Good idea to stick with a seller that looks like they specialize in just USB ports or similar components. If they also are selling lingerie & toys (not for kids) I have high doubt of the seller’s knowledge of the replacement parts or any other product they sell.
Also it is very important you get the year / generation correct. They use a different port for each variation with few exceptions. Match the P/N to any listings if they have them. Like this one would be '''SL056ZE''' .
P.S. For what it’s worth if you can remember the Kindle / Fire / FIre HD series generation matches the last digit of the year it is helpful. So 5th gen is 2015, 7th gen is 2017 etc. It DOES NOT apply to non color Amazon e-readers though.
Anyways hope this helps you and/or others.
