2n2222 Datasheet and History

Since Motorola launched the 2N2222 in 1962 it has become known as the 'universal transistor' - the most successful and widely used transistor in history.  Commonly referred to as the 'quad two' transistor, and also known as the PN2222, it is a small, common NPN BJT transistor used for general purpose low-power amplifying or switching applications. It is designed for low to medium current, low power, medium voltage, and can operate at moderately high speeds.  Billions of 2N2222 have been manufactured and are still in high volume production today.

Transistor Equivalents and Crosses

Everyday more and more visitors come to SupplyFrame to search for transistor equivalents and transistor cross reference devices.  We provide information not only on transistor equivalents but on component crosses for hundreds of commodity components.  If you are need equivalents or transistor cross reference information click this link and enter a part number or description. 

Where does all this information come from?   There are two answers to this.   

1. SupplyFrame partners with component manufacturers around the world.   Many of these manufacturers provide us with their cross reference guides so we can incorporate the knowledge across all manufacturers.  This data is one-way, for example if TI cross information is provided by TI we will help people find the TI equivalent for another manufacturers part - but not vice versa.   Why?  TI went to great expense to create this cross reference list and we use it to help TI grow thier business - using it in the reverse gives the same advantage to TI's competitors.
2. SupplyFrame's community contributions from our popular QuoteFX product.  QuoteFX is used heavily in BOM management and quoting by contract manufacturers and OEMs. In the course of it's use customer provide us with their equivalent and cross knowledge.   We will often incorporate this information if we feel it is accurate.

In all cases, you must review any cross or equivalent and determine if it fits your needs.   We make access to the transistor datasheet or any datasheet easy to obtain to support you on this.

You may also find this article from Dave Cushman's site helpful if you are looking for transistor equivalents for substituting modern transistors in 'elderly' projects.
