2N2222AL Equivalent & Substitute Parts Engineering Reference

Part Overview

The 2N2222AL, manufactured by Microchip Technology, is an NPN Bipolar Junction Transistor (BJT) specified for 50 V collector-emitter breakdown voltage, 800 mA maximum collector current, 500 mW power dissipation, and through-hole TO-18 (TO-206AA) metal can packaging. The product is actively available but RoHS non-compliant. Identifying alternative or equivalent models is necessary for use in RoHS-compliant applications, increased sourcing flexibility, or ensuring continuity when particular compliance or qualification standards are needed.

Substitute Part Grouping Explanation

Substitute parts for the 2N2222AL are grouped based on strict equivalence in electrical parameters (transistor type, maximum collector current, collector-emitter breakdown voltage, maximum power dissipation, minimum DC current gain, and Vce saturation at specified currents), through-hole mounting style, TO-18 (TO-206AA) package, and compliance status. All substitute relationships are determined solely by matching or exceeding the explicit listed parameters.

Key parameters for substitution:

• Transistor Type: NPN
• Collector-Emitter Breakdown Voltage (Vce max)
• Collector Current (Ic max)
• Vce Saturation at specified bias conditions
• DC Current Gain (hFE) at specified bias conditions
• Power Dissipation (Pd max)
• Mounting Type
• Package / Case
• RoHS Compliance Status
• Operating Temperature

Parameter Comparison

Engineering Selection Recommendations

• The 2N2222A from Good-Ark Semiconductor is ROHS3 compliant and otherwise matches all critical listed parameters except for a lower collector-emitter breakdown voltage (40 V versus 50 V) and a lower maximum operating temperature (175°C TJ).
• The JANS2N2222A from Microchip Technology is not RoHS compliant, but matches the key parameters, has the same maximum collector-emitter breakdown voltage (50 V), and includes military qualification (MIL-PRF-19500/255).
• Selection should be based on required RoHS compliance, application voltage thresholds, and qualification requirements as explicitly specified.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically equivalent to the 2N2222AL?
A: Substitute parts listed have matching core parameters for NPN type, collector current (800 mA max), power dissipation (500 mW max), DC current gain (100 min @ specified conditions), Vce saturation, mounting type (through hole), and TO-18 (TO-206AA) package. The Good-Ark 2N2222A has a lower collector-emitter breakdown voltage (40 V vs 50 V) and lower maximum operating temperature (175°C), while JANS2N2222A matches the 50 V rating.

Q: What are the packaging and mounting requirements for substitutes?
A: All parts use through-hole mounting and a TO-206AA (TO-18-3 Metal Can) package. Supplier device packages are listed as TO-18 or TO-18 (TO-206AA).

Q: Are RoHS-compliant alternatives available?
A: The Good-Ark Semiconductor 2N2222A is ROHS3 compliant. JANS2N2222A and 2N2222AL are both RoHS non-compliant.

Q: What compliance or qualification considerations are present?
A: JANS2N2222A offers military grade qualification (MIL-PRF-19500/255). The other models do not include such qualification in the provided data.

Q: How is DC current gain defined for substitution?
A: All listed parts have a minimum DC current gain of 100 at 150mA, 10V as required by the main part.

Q: What are the important electrical differences among the substitutes?
A: The main difference is the collector-emitter breakdown voltage: 2N2222A (Good-Ark Semiconductor) is 40 V, while both 2N2222AL and JANS2N2222A are 50 V. Other parameters are matched or within specified ranges according to the data provided.
