How to select electronic components?

#Discussion(IoTStack) [ via IoTForIndiaGroup ]

Surprisingly, many engineers do not pay enough attention to the task of selecting the right electronic components during the initial phase of their embedded product design.

Selecting right electronic component is one of the most critical & challenging aspect of product design. In this article, I do not aim to explain how to select different components like resistor, capacitor, transistor, digital IC, microcontrollers, relay, power management IC, connector, display, protection device, etc. as there is no one answer to this challenge. Correct answer is, you should know clearly what is your requirements w.r.t a particular component

Using components from previous proven design
New Parts Selection
Manufacturers

  Application Notes
  Reference Designs, Software Tools
  Technical Support / Design Review Support

Application Circuit Complexity
Electrical Parameters [voltage, current , power, accuracy, response time, speed, resolution, etc.]
Mechanical Parameters [dimension, package, weight, etc.]
Consideration w.r.t Manufacturing / Testing
Environmental Parameters : Temperature / Humidity / Pressure / Vibration
Long term availability / End of life (EOL)
Lead time
Cost
From where to Buy
Fall Back Solution / Assembly options
Design Reviews
Prototype before you plan production
