Which resistors to buy for MacBook Pro 820-3115-B

Hello and thanks for reading.

I bought schematics for my specific logic board. Need help identifying the parts to search online. Using Mouser and Digikey - not entirely sure on which resistors to buy to fix my board.

Macbook Pro Mid 2012 Unibody

820-3115-B

(Pictures attached)

Board Viewer shows the resistors I need as:

R7919, R7052

5%

1/16W

MF-LF

402

@mkoenig10 this is just for completion sake since I am certain you already have this fixed. The resistor R7919 is listed as “No Stuff” which for Apple schematic means, it is not there. Those are either from predesign or for future expansion. You will see some solder pads but if you look closely you’ll find they have never been occupied. This resistor (or the absence of it) will not be an issue for your MBP.

Resistor R7052 is a 0 ohm resistor. 0 ohm resistors are no more than a wire link packaged in the same physical package format as a resistor. All it does is connects the traces. Components are easier to place than a wire bridge during manufacturing of the board and are actually quite common. So, you can either get a   0 ohm 1/16W resistor in a 0402 package or you could apply a jumper in between.

Here is more info on what a 0 Ohm resistor does etc.
