hello I have a macbook pro 13, which was spilled liquid, I opened and cleaned with isopropyl alcohol. but realized it had released three components, and would like to know which model or type to try to change.
Questa è una buona domanda?

Shimamoto, took me a while to find a match based on your images. First image shows:"
Reference designator C7242 is a capacitor 0.001UF 20% Cerm 402
Reference designator C7241 is a capacitor 1UF 10% 25V X5R 603
Reference designator C7281 is a capacitor 1UF 10% 25V X5R 603
Reference designator C7282 is a capacitor0.001UF 20% Cerm 402
Those are part of your 5V/3.3V SUPPLY circuit
Second image shows Reference designator U5703 SN74LVC1G10 which is a SINGLE 3-INPUT POSITIVE-NAND GATE The datasheet is available here. It is part of your SMC_MANUAL_RESET LOGIC circuit. Hope this helps, good luck

Cerm 402 package voltage is 25v ? I found this X5R 603, but the other I am not able find it. I should look for CERM 402 or c7242?
Shimamoto, C7242 etc. is only a reference for the location of the part on your board, not a search term. You need to know that 402 is nothing but the package size, the physical dimension, not the electronic dimension. 0402 (1005 metric): 1.0 mm × 0.5 mm (0.039 in × 0.020 in). Typical power rating for resistors = 0.1 or 0.062 watt. X5R is a description of the dielectric constant determined by the ceramic material. This is only one of the factors that determines the capacitance value of a capacitor
I do not know where you are located, so here are the parts from the company I deal with a lot. I am certain you can get those parts from many other suppliers as well. For C7242 and C7282 anyone of these will work. For C7241 and C7281 use this page.

Post some images of the damage so we can see what you see.

Good pictures, now all you have to do is to back out a bit so we can see where those parts are located on the board.:-)

Ok here some new pictures.

Thanks for the images.

when I buy the capacitors can buy any manufacturer? since that is the same right? But what is the right model? C7242 OR Cerm 402?
