2A302J is what electronic component ?

Click For Summary

Discussion Overview

The discussion centers around identifying the electronic component labeled as 2A302J. Participants explore its possible classifications, characteristics, and specifications, including its appearance and function. The scope includes technical identification and component specifications.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants suggest that 2A302J may refer to an integrated circuit (IC).
  • Another participant notes that searches yield results for both capacitors and resistors, indicating a potential value of 3000 (Ohms or capacitance).
  • Questions are raised about the physical characteristics of the component, such as dimensions, shape, number of leads, and whether it is surface mount or through hole.
  • One participant proposes that it could be a 2SA302 transistor, mentioning that the "2SA" part might not always be printed on transistors.
  • A later reply identifies it as a 2SA302 transistor, providing detailed specifications including type (Germanium PNP), maximum collector current, and other electrical characteristics.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding the identification of the 2A302J component, with no consensus reached on its exact classification or characteristics.

Contextual Notes

Limitations include uncertainty about the component's physical form and the implications of its designation, as well as the potential for multiple interpretations of the part number.

What does it look like? If you go to www.findchips.com and do a search on it, you get matches for both capacitors and resistors. The 302J part implies a value of 30*10^2 = 3000 somethings (Ohms for resistors, microFarads or picoFarads for capacitors).

What are the dimensions and shape of the component you are lookikng at? How many leads? Surface mount or through hole? If through hole, is it axial (leads straight out the ends) or radial (leads perpendicular to the component body)?
 


Could also be a 2SA302 transistor.

Sometimes they don't print the "2SA" part on the transistors.

Does it look like a transistor? Does it have 3 wires coming out of it?
 


This is the circuit
 


It's a transistor:
