MPS2222A-AP Equivalent & Substitute Parts

Part Overview

The MPS2222A-AP is an NPN bipolar junction transistor manufactured by Micro Commercial Co, designed for general-purpose switching and amplification applications. This device features a 40 V collector-emitter breakdown voltage, 600 mA maximum collector current, and 300 MHz transition frequency in a Through Hole TO-92 package. The MPS2222A-AP is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across voltage, current, and frequency specifications while accommodating the Through Hole TO-92 package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2222A-AP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor Type: NPN
• Mounting Type: Through Hole
• Package / Case: TO-92-3 (TO-226AA Formed Leads)
• Current - Collector (Ic) (Max): 600 mA
• Vce Saturation (Max) @ Ib, Ic: 1 V @ 50 mA, 500 mA
• Current - Collector Cutoff (Max): 10 nA
• DC Current Gain (hFE) (Min) @ Ic, Vce: 100 @ 150 mA, 10 V
• Frequency - Transition: 300 MHz

Allowable Variation Parameters:

• Voltage - Collector Emitter Breakdown (Max): Substitute parts may equal or exceed the 40 V specification
• Power - Max: Substitute parts may equal or exceed the 600 mW specification
• Operating Temperature (Max): Substitute parts may equal or exceed 150°C

The identified substitute parts KSP2222ATA, PN2222TA, and PN2222TF meet the mandatory matching criteria. PN2222TA and PN2222TF operate at a reduced Voltage - Collector Emitter Breakdown of 30 V, which is acceptable for applications designed within the 30 V operating envelope.

Parameter Comparison

Engineering Selection Recommendations

KSP2222ATA (Fairchild Semiconductor) is the primary direct substitute for the MPS2222A-AP. This part maintains full electrical equivalence across all parameters, including the 40 V collector-emitter breakdown voltage. KSP2222ATA is in Active product status with 55,200 units in stock, ensuring long-term availability. The part is suitable for applications requiring the full 40 V operating envelope.

PN2222TA (onsemi) is a functionally equivalent substitute with a reduced collector-emitter breakdown voltage of 30 V. This part is classified as Last Time Buy, indicating limited future availability. PN2222TA is ROHS3 compliant and suitable for applications designed to operate within the 30 V specification. Current inventory is 4,556 units.

PN2222TF (Fairchild Semiconductor) is an Active substitute with a 30 V collector-emitter breakdown voltage specification. This part maintains all other electrical parameters equivalent to the MPS2222A-AP and is suitable for 30 V applications. PN2222TF has the highest inventory availability at 64,868 units, supporting sustained production requirements.

For new designs or applications requiring the full 40 V operating range, KSP2222ATA is the recommended selection. For applications operating within 30 V specifications, PN2222TF offers superior long-term availability as an Active product.

Frequently Asked Questions (FAQ)

Q: Can PN2222TA or PN2222TF be used in place of MPS2222A-AP in all applications?

A: PN2222TA and PN2222TF are electrically equivalent to MPS2222A-AP for applications designed to operate at 30 V or below. Applications requiring the full 40 V collector-emitter breakdown voltage specification must use KSP2222ATA or equivalent 40 V rated devices.

Q: What is the difference between KSP2222ATA and the PN2222 series?

A: KSP2222ATA maintains the 40 V collector-emitter breakdown voltage of the original MPS2222A-AP. PN2222TA and PN2222TF operate at 30 V maximum collector-emitter breakdown voltage. All three parts share identical collector current, saturation voltage, cutoff current, current gain, power dissipation, and transition frequency specifications.

Q: Are all substitute parts available in the same TO-92-3 package?

A: Yes. KSP2222ATA, PN2222TA, and PN2222TF are all supplied in the Through Hole TO-92-3 (TO-226AA Formed Leads) package, ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What is the product status significance for long-term supply planning?

A: KSP2222ATA and PN2222TF are classified as Active products, indicating ongoing manufacturing and long-term availability. PN2222TA is Last Time Buy, meaning production will cease and inventory will be depleted. For new designs requiring sustained production support, Active status products are preferred.

Q: Do the substitute parts meet RoHS compliance requirements?

A: PN2222TA is ROHS3 compliant. KSP2222ATA and PN2222TF compliance status is not specified in the provided data. Compliance verification with the original equipment manufacturer is required for applications with specific regulatory requirements.
