okie then, what is this
n-channel, p-channel, voltage regulator, diode? what? seriously
spoiler its a NTD 2955 P channel FET, you would know that in a schematic, the photo-realistic part is worthless, and a fritzing diagram is not very much help to those who dont have the exact same breadboar/perfboard layout, those caps come in a dozen different sizes with and without stripes, they may have arrows, they may be NP cap's depending on what you get your hands on.
Grab a blue cap with a stripe on it is a poor description of what the thing actually is
