Determining loose capacitors after water damage

I have a water damaged iPhone 6 plus logic board. I have shown below the NAND area of the logic board, and I have circled and labeled 5 capacitors that are burnt/loose. Does anybody know exactly which capacitors these are so I can buy replacement ones especially number 1? If anybody could tell me exactly what to look up at mouser.com that would be amazing.

If anybody can tell me what any of these capacitors are I would greatly appreciate it. Especially number 1 because it is so badly burnt. My iPhone will not start up/show in iTunes and I believe this is the reason why. I already have a micro-solderer who will put these on if I can figure out what capacitors they are.

Thank you for any help I can get,

Joe

Hello Old Turkey!! Thank you for replying, I really appreciate it! The number you are asking for is 820-3675 and the model is an Iphone 6 Plus. Not an Iphone 6s Plus. I have added three pictures for clarity on location on the board. I updated which parts I have "circled" and I only need three parts identified. Number 1 which I believe is a resistor, and numbers 2&3 which I believe are capacitors. Please let me know if there is anything else I should add in order to help. Thank you again, and I really appreciate it!!!

If it helps I believe that 2 and 5 are the same size (T5301), and 1 and 4 are the same size, but I don't know what 1 and 4 are. Nor do I know what 3 is, but I believe 2 and 5 are the same size as most of the capacitors on the logic board. Please let me know if this is correct, and any information on 1 would be really really appreciated.

Thank you,

Joe

If anybody has any information on even the cap values of these parts, even that would extremely helpful.

I don't know if anybody has been looking, or if anybody has seen this post, but I have an update. I've figured out what those capacitors are, and I believe I have the correct ones ordered on Digikey.com. Once they arrive I will have my professional Micro-Solderer take the bad ones off and put the old ones on and I will post an update on whether or not there's any success with starting my Iphone or if it is detected in iTunes.

@joeshmoe what is the 820-XXX number on your board or what exact model is it out of? 6S+? Take anohter picture but this time zoom out so we can see the location of the components in relation to the board.

@oldturkey03 I have posted an answer to my own question for you. It's not an answer, it's a couple more pictures added for clarity in order to be better able to help. Please take a look, and let me know if there is any other information I should add!!! Thank you for the help!

@joeshmoe this is just to identify the components listed in your images

1) Reference designator VR3101_RF is a ESDAVLC5-4BU4 4-line bidirectional transient surge voltage suppressor and it is part of the Sim card ESD protection circuit

2) Reference designator C3101_RF is a 2.2uF 6.3V 20% capacitor in a 0201 package

3) Reference designator C0616 is a 10uF 6.3V 20% capacitor in a 0402 package.

@oldturkey03 thank you so much for the help!! For number 1, the VR3101_RF, will this part from Digikey work as a replacement: YAG3101CT ???!

さんによる

@joeshmoe the YAG3101CT is a resistor and will not work. ESDAVLC5-4BU4 is more of a diode for circuit protection. The part is a bit elusive. There are a few different ones on here but we do not know the value of the 4BU4 so just to substitute may not be a good idea. Try to contact this vendor and see if they carry it.

さんによる

@oldturkey03 I thought that the part VR3101_RF was a variable resistor, and since part number YAG3101CT is a resistor, I thought that would work? If not i'll try to figure out what the value of 4BU4 is. Also, last question... If this part is totally destroyed and non operational, will this alone prevent the iPhone from starting up?
