The 2N2222 is one of the most commonly used transistors in projects requiring bipolar transistors. They were once easy to find at local electronics stores, where anyone from hobby enthusiasts to businesses building multiple devices could find the parts they needed for a project. While the 2N2222 is still available, it can be difficult to find a brick-and-mortar location to purchase 2N2222 transistors in New Jersey. Fortunately, online stores and express delivery have made component shopping even easier than it was in the days of the local corner electronics store.
Pick the Right Transistor
Because the 2N2222 has been around for more than 50 years, many people assume it is the right pick for every project. While this workhorse small transistor is great for a range of applications, it is not always the best pick. Picking the right transistor means looking at the project specifications for the currency rating, power dissipation, maximum voltage, current gain, temperature rating, and transition frequency the project needs. The most economical choice for any project is the component that meets the project needs without exceeding them.
Other Transistor Options
If examining the project reveals that the 2N2222’s specifications may not be right for the project, there are several similar options. The 2N2222A is almost identical to the 2N2222 but is an updated version, capable of handling higher voltages. However, it is usually more expensive. The BC548 is similar but is only rated for low voltage and low current usages. The 2N2907 is considered to be the PNP equivalent of the 2N2222. The 2N3904 has a significantly smaller current capacity, but is otherwise similar to the 2N2222 and would be a good choice for projects requiring that the transistor amplify current. The 2N2219 serves the same function as the 2N2222 but with a higher power dissipation rating.
Project Ideas for 2N2222 Transistors
Because of their popularity, people use 2N2222 transistors for a wide variety of projects. Some of the most innovative and easy DIY projects using 2N2222 transistors include anti-theft devices for wallets or keys, switches, and even homemade lie detector test equipment.
Finding 2N2222 Transistors
Finding 2N2222 transistors seems easy, but it is important to make sure that the parts meet JEDEC specifications and are right for your project. Get information about 2N2222 Transistors in New Jersey to learn how to place an order.
