> Common "jellybean" passive components like resistors, capacitors, inductors... are designed to be standardized and interchangeable with any other component of the same specifications. The remaining factor might be cost and manufacturer (their quality control), but knowing which makes of capacitor are consistently reliable is hardly trade secret knowledge. Not even close to true for capacitors and inductors. True for resistors mostly, but inductors and capacitors have wildly different specifications depending on their intrinsic parameters. The derating curves (AC, DC, etc) vary wildly depending on the individual part selection. One capacitor may have double or triple the capacitance of another for the same size, nominal rating, and type at a specific voltage condition. Sure you can overbuild and not worry too much, but given the wildly small size of phones don’t be shocked if the individual components selected are very critical.
