MPS3392 Equivalent & Substitute Parts

Part Overview

The MPS3392 is an NPN bipolar junction transistor manufactured by onsemi, housed in a TO-92-3 through-hole package. This device is rated for 25 V collector-emitter breakdown voltage and 100 mA maximum collector current, with a maximum power dissipation of 625 mW. The MPS3392 is classified as obsolete, necessitating identification of functionally equivalent substitute components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPS3392 are selected based on electrical and mechanical compatibility within the following criteria:

Electrical Compatibility Parameters:

• Transistor type must be NPN
• Collector-emitter breakdown voltage must equal or exceed 25 V
• Maximum collector current must equal or exceed 100 mA
• Maximum power dissipation must equal or exceed 625 mW
• Package and mounting type must be TO-92-3 through-hole

Substitution Logic: The PN2222TA and PN2222TF both exceed the electrical specifications of the MPS3392. Both devices provide 30 V breakdown voltage (exceeding the 25 V requirement), 600 mA collector current (exceeding the 100 mA requirement), and 625 mW power rating (meeting the requirement). Both are housed in TO-92-3 through-hole packages, ensuring mechanical and pin compatibility. These devices function as direct substitutes in applications where the MPS3392 was originally specified.

Engineering Selection Recommendations

PN2222TA (onsemi): The PN2222TA is classified as Last Time Buy status. This part provides superior electrical performance compared to the MPS3392, with higher voltage and current ratings. The device is ROHS3 compliant and REACH unaffected. PN2222TA is suitable for applications requiring compliance with modern environmental regulations.

PN2222TF (Fairchild Semiconductor): The PN2222TF is classified as Active product status, indicating ongoing availability and manufacturer support. This part provides identical electrical specifications to the PN2222TA and is available in bulk packaging with the highest inventory level (64,868 pieces). The PN2222TF is suitable for applications requiring long-term component availability and supply chain continuity.

Both substitute parts are mechanically and electrically compatible with the MPS3392. Selection between PN2222TA and PN2222TF should be based on supply chain requirements, compliance certifications, and product lifecycle considerations specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the PN2222TA or PN2222TF be used as direct replacements for the MPS3392?

A: Yes. Both the PN2222TA and PN2222TF are direct substitutes for the MPS3392. All three devices share identical TO-92-3 through-hole packaging with the same pin configuration. The substitute parts exceed the electrical specifications of the MPS3392 across all critical parameters: breakdown voltage, collector current, and power dissipation.

Q: What are the key differences between the PN2222TA and PN2222TF?

A: The primary differences are manufacturer and product status. The PN2222TA is manufactured by onsemi and classified as Last Time Buy. The PN2222TF is manufactured by Fairchild Semiconductor and classified as Active. Both devices have identical electrical specifications and package type. The PN2222TF has significantly higher inventory availability.

Q: Are there any compliance differences between these parts?

A: Yes. The PN2222TA is ROHS3 compliant, while the MPS3392 is RoHS non-compliant. The PN2222TF compliance status is not specified in the provided data. Applications requiring RoHS compliance should specify the PN2222TA.

Q: Will circuit performance change if I substitute the MPS3392 with PN2222TA or PN2222TF?

A: Circuit performance will not degrade. The substitute parts have higher electrical ratings, which provides additional design margin. The DC current gain specifications differ at different operating points, but both substitute parts are suitable for small-signal amplification applications where the MPS3392 was originally used.

Q: Are the packages physically identical?

A: Yes. All three devices use the TO-92-3 through-hole package with formed leads. The physical dimensions and pin spacing are identical, allowing direct board-level substitution without layout modifications.
