Chosen Solution

I have a MacBook Pro retina 13" late 2013 One day he refused to see the SSD, like an innocent I ordered an SSD for 300 CAD, I installed it and Na it did not see it. I decided to go to Apple store. they kept it for a couple of days and told me afterwards that it is a logic board issue and costs 10,000 CAD :) you know. I went on Internet and followed the instructions of a video on IFIXIT. I removed the logic board and looked at it under a magnifier. Just behind the plug where the SSD sits, on the other side of the board I discovered a surface mount component that has leaked a greenish material and was obviously the problem to repair. I copied the writing on it so I can buy it and install it (DDP 3X 8B) the surprise is nothing on the internet, nothing at an electronics store, and nothing on google knows what the hack this component is! Can anyone help? would be much appreciated. I can post pics if needed.

First: Do what Oldturkey03 said. Second: $10,000 Canadian Dollars equals $7,839.50 US Dollars, is that correct? Third: Apple offers a “Flat Rate Repair” program in the USA. They will fix any and all things on your Mac if it has not received liquid or impact damage. Simply call at 1-800=MYAPPLE. This program takes four days, shipping is overnight express, total with tax and shipping is $357 in Texas USoA.
