VN2222LLRLRAG N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The VN2222LLRLRAG is an N-Channel MOSFET manufactured by onsemi, rated for 60V drain-to-source voltage with 150mA continuous drain current at 25°C. The device is housed in a TO-92-3 (TO-226) through-hole package and dissipates a maximum of 400mW. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, and thermal characteristics while accommodating available packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the VN2222LLRLRAG is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 60V minimum
• Gate Voltage (Vgs) Max: ±20V
• Operating Temperature Range: -55°C to 150°C
• Mounting Type: Through Hole

Performance Parameters (Substitutes Must Meet or Exceed):

• Continuous Drain Current (Id) @ 25°C: 150mA minimum
• Power Dissipation (Max): 400mW minimum
• Rds On (Max) @ 10V: 7.5 Ohm maximum

Package Compatibility: Substitute parts must be compatible with TO-92-3 through-hole footprints or equivalent E-Line packages designed for TO-92 compatibility.

The substitute parts ZVN3306A and ZVN3306ASTZ meet all critical matching parameters and exceed performance specifications in continuous drain current (270mA), power dissipation (625mW), and on-resistance (5 Ohm @ 500mA, 10V). Both devices maintain identical voltage ratings, gate specifications, and operating temperature ranges.

Engineering Selection Recommendations

ZVN3306A (Bulk Packaging)

The ZVN3306A is an active product manufactured by Diodes Incorporated and is ROHS3 compliant. This part provides direct electrical and mechanical compatibility with the VN2222LLRLRAG in standard TO-92-3 packaging. The ZVN3306A exceeds the original part specifications in continuous drain current (270mA vs. 150mA) and power dissipation (625mW vs. 400mW), providing enhanced thermal and current handling margins. This part is suitable for applications requiring standard bulk component procurement.

ZVN3306ASTZ (Tape & Reel Packaging)

The ZVN3306ASTZ is an active product manufactured by Diodes Incorporated and is ROHS3 compliant. This part provides identical electrical specifications to the ZVN3306A but is supplied in Tape & Reel (TR) packaging with E-Line (TO-92 compatible) case format. The ZVN3306ASTZ is designed for automated assembly processes and high-volume production environments. Inventory availability (25,400 Pcs) supports sustained production requirements.

Compliance and Regulatory Status

Both substitute parts maintain REACH Unaffected status and EAR99 ECCN classification, consistent with the original VN2222LLRLRAG. Moisture Sensitivity Level (MSL) is rated as 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the ZVN3306A or ZVN3306ASTZ be used as direct replacements for the VN2222LLRLRAG?

A: Yes. Both substitute parts meet all critical electrical parameters: 60V Vdss rating, ±20V gate voltage specification, -55°C to 150°C operating temperature range, and through-hole mounting compatibility. The substitutes exceed the original part in continuous drain current and power dissipation, providing improved performance margins.

Q: What is the difference between ZVN3306A and ZVN3306ASTZ?

A: Both parts are electrically identical with matching specifications. The primary difference is packaging format: ZVN3306A is supplied in bulk, while ZVN3306ASTZ is supplied in Tape & Reel format with E-Line (TO-92 compatible) case configuration. ZVN3306ASTZ is optimized for automated assembly processes.

Q: Are there any thermal or current handling limitations when substituting these parts?

A: No. The substitute parts (ZVN3306A and ZVN3306ASTZ) provide superior thermal performance with 625mW maximum power dissipation compared to the original 400mW specification. Continuous drain current is rated at 270mA, exceeding the original 150mA rating. On-resistance is reduced to 5 Ohm at 500mA, 10V, compared to the original 7.5 Ohm specification.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both ZVN3306A and ZVN3306ASTZ are ROHS3 compliant. The original VN2222LLRLRAG RoHS status is not specified in available documentation.

Q: What is the gate threshold voltage difference between the original and substitute parts?

A: The gate threshold voltage (Vgs(th)) @ 1mA is 2.5V for the VN2222LLRLRAG and 2.4V for both substitute parts. This 0.1V difference is within normal device variation and does not affect circuit compatibility.

Q: Can I use ZVN3306ASTZ in applications originally designed for standard TO-92-3 packaging?

A: Yes. The ZVN3306ASTZ E-Line package is designed for TO-92 compatibility and maintains the same pin configuration and footprint as the original TO-92-3 package. The E-Line format is optimized for tape-and-reel automated assembly but is mechanically compatible with standard through-hole PCB layouts.

Q: What is the input capacitance difference, and does it affect circuit performance?

A: The input capacitance (Ciss) is 60 pF @ 25V for the VN2222LLRLRAG and 35 pF @ 18V for the substitute parts. The lower capacitance in the substitutes may improve switching speed in high-frequency applications, but this difference does not prevent substitution in standard switching applications.

Q: Are there any moisture sensitivity or storage requirements for these parts?

A: No. All three parts (VN2222LLRLRAG, ZVN3306A, and ZVN3306ASTZ) are rated MSL 1 (Unlimited), indicating no special moisture handling, baking, or storage requirements.
