2N4402_J14Z PNP Bipolar Junction Transistor Equivalent & Substitute Parts

Part Overview

The 2N4402_J14Z is a PNP Bipolar Junction Transistor manufactured by onsemi, rated for 40 V collector-emitter breakdown voltage and 600 mA maximum collector current. This device is packaged in a TO-92-3 through-hole configuration and is rated for 625 mW maximum power dissipation across an operating temperature range of -55°C to 150°C.

The 2N4402_J14Z is classified as an obsolete product. Locating equivalent substitute parts becomes necessary when original inventory is depleted or when design flexibility is required for procurement optimization. Substitute parts must maintain electrical compatibility within the specified parameter tolerances and physical compatibility with the TO-92-3 package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2N4402_J14Z is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Transistor type must be PNP
• Voltage - Collector Emitter Breakdown (Max) must be ≥ 40 V
• Power - Max must be ≥ 625 mW
• Operating temperature range must encompass -55°C to 150°C
• Package / Case must be TO-92-3 (TO-226-3, TO-226AA equivalent)

Current Rating Consideration: The 2N4402_J14Z specifies a maximum collector current of 600 mA. Substitute parts with lower maximum collector current ratings (such as 200 mA) are classified as restricted substitutes. These parts are electrically compatible for applications where the circuit design operates below the substitute part's current rating. However, they cannot be used in applications requiring the full 600 mA capability of the original part.

The 2N3906BU meets all voltage, power, temperature, and package requirements but operates at a reduced maximum collector current of 200 mA, making it suitable only for circuits designed within this current envelope.

Engineering Selection Recommendations

For Direct Substitution (Full Compatibility): No substitute part in the provided list maintains full electrical equivalence across all parameters. The 2N4402_J14Z operates at 600 mA maximum collector current, and no substitute meeting this specification is listed.

For Current-Limited Applications (Restricted Substitution): The 2N3906BU (Fairchild Semiconductor) is suitable for applications where circuit design operates at or below 200 mA collector current. This part is currently in active production status with 50,200 units in stock, providing superior procurement availability compared to the obsolete 2N4402_J14Z. The 2N3906BU maintains identical voltage rating (40 V), power dissipation (625 mW), temperature range (-55°C to 150°C), and package configuration (TO-92-3).

Compliance and Certification: Both parts carry ECCN classification EAR99 and are REACH Unaffected, meeting standard export and environmental compliance requirements for electronic components.

Frequently Asked Questions (FAQ)

Q: Can the 2N3906BU replace the 2N4402_J14Z in all applications?

A: The 2N3906BU is a restricted substitute. It is compatible only in applications where the circuit design operates at collector currents of 200 mA or below. Applications requiring the full 600 mA capability of the 2N4402_J14Z cannot use the 2N3906BU without circuit redesign.

Q: Are the TO-92-3 packages physically identical?

A: Yes. Both the 2N4402_J14Z and 2N3906BU use the TO-92-3 (TO-226-3, TO-226AA) package, ensuring identical physical footprint and pin configuration for through-hole PCB mounting.

Q: What is the primary difference between these two parts?

A: The maximum collector current rating differs significantly. The 2N4402_J14Z is rated for 600 mA, while the 2N3906BU is rated for 200 mA. All other electrical parameters—voltage rating, power dissipation, temperature range, and saturation characteristics—are compatible.

Q: Why is the 2N4402_J14Z obsolete?

A: The 2N4402_J14Z is classified as obsolete by the manufacturer. The 2N3906BU represents the active production alternative in the PNP transistor family with similar voltage and power ratings.

Q: Can I use the 2N3906BU if my circuit only draws 150 mA?

A: Yes. If your circuit design operates at 150 mA or below, the 2N3906BU is fully compatible with the 2N4402_J14Z across all electrical and thermal parameters.

Q: What certifications apply to both parts?

A: Both parts carry ECCN EAR99 classification and are REACH Unaffected, meeting standard compliance requirements for unrestricted commercial distribution.
