MPS2222 Equivalent & Substitute Parts

Part Overview

The MPS2222 is an NPN bipolar junction transistor (BJT) manufactured by onsemi, designed for small-signal switching and amplification applications. The device operates at a maximum collector current of 600 mA with a collector-emitter breakdown voltage of 30 V and a maximum power dissipation of 625 mW. The MPS2222 is packaged in a through-hole TO-92 (TO-226-3) configuration with a transition frequency of 250 MHz.

The MPS2222 is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this component is specified. Substitute parts must maintain electrical and mechanical compatibility within the defined parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the MPS2222 are identified based on strict electrical and mechanical parameter compatibility. The following criteria define acceptable substitution:

Electrical Compatibility Requirements:

• Transistor type must be NPN
• Maximum collector current (Ic) must be greater than or equal to 600 mA
• Collector-emitter breakdown voltage (VCEO) must be greater than or equal to 30 V
• Maximum power dissipation must be greater than or equal to 625 mW
• DC current gain (hFE) minimum must be greater than or equal to 100 at specified test conditions
• Collector cutoff current (ICBO) must not exceed 10 nA

Mechanical Compatibility Requirements:

• Mounting type must be through-hole
• Package must be TO-92-3 or equivalent TO-226-3 configuration

Performance Considerations:

• Transition frequency may exceed the original specification
• Vce saturation characteristics may differ within acceptable operating ranges
• Operating temperature range may extend beyond the original specification

The PN2222TF meets all electrical and mechanical substitution criteria for the MPS2222.

Engineering Selection Recommendations

MPS2222 (onsemi): The MPS2222 is classified as obsolete and is not recommended for new designs. However, 923 pieces are currently in stock. This part is RoHS non-compliant and carries no active manufacturer support. The MPS2222 is suitable only for legacy system maintenance or repair applications where the original specification is mandatory.

PN2222TF (Fairchild Semiconductor): The PN2222TF is an active product with 64,868 pieces in stock. This substitute meets all electrical and mechanical requirements for direct replacement of the MPS2222. The PN2222TF offers improved performance characteristics, including lower saturation voltage (1 V versus 1.6 V) and higher transition frequency (300 MHz versus 250 MHz). The PN2222TF is suitable for both new designs and legacy system replacements. Compliance certifications (ECCN: EAR99, HTSUS: 8541.21.0075) are equivalent to the original part.

For applications requiring active manufacturer support, ongoing availability, and compliance with current standards, the PN2222TF is the recommended substitute for the obsolete MPS2222.

Frequently Asked Questions (FAQ)

Q: Can the PN2222TF directly replace the MPS2222 in existing circuits?

A: Yes. The PN2222TF meets all electrical and mechanical specifications required for direct substitution. Both devices are NPN transistors with identical maximum ratings for collector current (600 mA), collector-emitter breakdown voltage (30 V), and power dissipation (625 mW). Both are packaged in TO-92-3 through-hole configuration. The PN2222TF exhibits superior performance with lower saturation voltage and higher transition frequency, making it functionally compatible in all applications where the MPS2222 was specified.

Q: What are the key differences between the MPS2222 and PN2222TF?

A: The primary differences are product status and performance characteristics. The MPS2222 is obsolete with no active manufacturer support, while the PN2222TF is an active product. The PN2222TF has a lower Vce saturation voltage (1 V versus 1.6 V at 50 mA, 500 mA), resulting in reduced power dissipation during saturation. The PN2222TF also has a higher transition frequency (300 MHz versus 250 MHz), enabling faster switching operation. Both devices maintain identical maximum electrical ratings and package configuration.

Q: Are there any temperature range limitations when substituting the PN2222TF for the MPS2222?

A: The MPS2222 specifies an operating temperature range of -55°C to 150°C. The PN2222TF datasheet indicates operation up to 150°C. For applications requiring operation below 0°C, verification of the PN2222TF low-temperature performance characteristics is necessary based on the specific application requirements and the substitute device's detailed specifications.

Q: Is the TO-92-3 package configuration identical between both devices?

A: Both the MPS2222 and PN2222TF use TO-92-3 through-hole packaging. The MPS2222 is specified as TO-226-3 with long body leads, while the PN2222TF is specified as TO-226AA with formed leads. Both configurations are mechanically compatible with standard TO-92 PCB footprints and breadboard layouts. Pin assignments (base, collector, emitter) are identical.

Q: What is the inventory status for each part?

A: The MPS2222 has 923 pieces in stock as new original inventory. The PN2222TF has 64,868 pieces in stock as new original inventory. The PN2222TF offers significantly greater availability for immediate procurement.

Q: Are there compliance or regulatory differences between the MPS2222 and PN2222TF?

A: The MPS2222 is RoHS non-compliant. The PN2222TF compliance status is not specified in the provided data. Both devices share identical ECCN (EAR99) and HTSUS (8541.21.0075) classifications. For applications with specific RoHS or environmental compliance requirements, the substitute device's full compliance documentation must be reviewed.
