There are several alternatives for MMBT2222A, which is a popular NPN bipolar junction transistor commonly used in low-power amplifier and switching applications.
One alternative is the 2N2222A transistor, which is also an NPN bipolar junction transistor with similar electrical characteristics to the MMBT2222A. The 2N2222A transistor has a higher maximum collector current and power dissipation rating compared to the MMBT2222A.
Another alternative is the BC547 transistor, which is also an NPN bipolar junction transistor with similar electrical characteristics. The BC547 transistor is commonly used in audio amplifiers, switch-mode power supplies, and signal processing applications.
The PN2222A transistor is another alternative, which is also an NPN bipolar junction transistor with similar electrical characteristics to the MMBT2222A. It has a higher collector current rating and power dissipation compared to the MMBT2222A.
