I am in desperate need of some assistance.
Adafruit has a breakout board that I pretty much would like to duplicate, with a through hole design, and it is not because I am too cheap to buy it, but because I will be working in close quarters and I do not have the room for attaching the board. Believe me there is a lot headache associated with this task. I want to duplicate their circuitry because I want a tact switch to control the 7.5VDC/1.5A power supply going to a Propeller Proto Board.
Anyhow, the product that I would like to duplicate is here: http://www.adafruit.com/blog/2013/06/07/new-product-adafruit-push-button-power-switch-breakout/
and here is the schematic: http://www.adafruit.com/datasheets/1400sch.png
First off, I want to rip Q1 and R4 out of the schematic, because I do not want or need that kind of shut down. I don't foresee this as a problem, but I could be wrong.
Secondly, is it acceptable to use 1/4W resistors for R2 and R3?
And thirdly, I need a drop in through hole replacement part for this MOSFET: http://www.adafruit.com/datasheets/DMG3415U.pdf
, is there any MOSFET available that would do the job?
I would not know what to look for when trying to find a through hole MOSFET replacement part, so any guidance you might be able to provide, would be greatly appreciated.
