MPS2222RLRPG Equivalent & Substitute Parts

Part Overview

The MPS2222RLRPG is a small-signal NPN bipolar junction transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a 30 V collector-emitter breakdown voltage, 600 mA maximum collector current, and 625 mW power dissipation in a through-hole TO-92 package. The part is currently listed as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across key parameters including collector current, breakdown voltage, DC current gain, and operating temperature range while accommodating different packaging technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2222RLRPG is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Transistor Type: NPN (required match)
• Current - Collector (Ic) (Max): 600 mA (required match)
• Voltage - Collector Emitter Breakdown (Max): minimum 30 V (equal or higher acceptable)
• DC Current Gain (hFE) (Min): 100 @ 150mA, 10V (required match)
• Operating Temperature Range: -55°C to 150°C (required match)
• Current - Collector Cutoff (Max): 10 nA (required match)

Secondary Considerations:

• Vce Saturation characteristics
• Frequency - Transition: 250 MHz minimum
• Power dissipation capability
• Mounting type and package compatibility

The substitute parts listed below satisfy these criteria within their respective packaging technologies (through-hole or surface-mount).

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole Applications (Direct Package Compatibility):

PN2222TF is the primary substitute for through-hole designs. This part is manufactured by Fairchild Semiconductor and maintains active product status with 64,868 units in stock. It matches all critical electrical parameters including 600 mA collector current, 30 V breakdown voltage, 100 hFE minimum, and -55°C to 150°C operating range. The PN2222TF is packaged in TO-92-3 (TO-226AA) formed leads, providing mechanical compatibility with the MPS2222RLRPG footprint.

PN2222TA is an alternative through-hole substitute from onsemi with 4,556 units available. This part carries Last Time Buy status and is ROHS3 compliant. It satisfies all primary electrical criteria and maintains the same TO-92-3 package. However, the Last Time Buy designation indicates limited future availability.

For Surface-Mount Applications (Package Technology Change):

MMBT2222ALT1G is the surface-mount equivalent, manufactured by onsemi with 725,400 units in stock and active product status. This part exceeds the 30 V breakdown voltage requirement at 40 V, maintains 600 mA collector current, and meets all DC current gain specifications. The MMBT2222ALT1G is AEC-Q101 qualified and ROHS3 compliant, packaged in SOT-23-3 (TO-236). Surface-mount implementation requires PCB layout and assembly process modifications.

Compliance Considerations:

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification. PN2222TF and MMBT2222ALT1G are active products with established supply chains. PN2222TA, while electrically compatible, carries Last Time Buy status and should be evaluated for long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can PN2222TF directly replace MPS2222RLRPG in existing designs?

A: Yes. PN2222TF maintains electrical equivalence across all critical parameters: 600 mA collector current, 30 V breakdown voltage, 100 hFE minimum, and -55°C to 150°C operating temperature. Both parts use TO-92-3 through-hole packaging, enabling direct PCB footprint compatibility without layout modifications.

Q: What is the difference between PN2222TA and PN2222TF?

A: Both parts are electrically equivalent NPN transistors with identical collector current (600 mA), breakdown voltage (30 V), and operating temperature range (-55°C to 150°C). The primary difference is manufacturer: PN2222TA is from onsemi with Last Time Buy status, while PN2222TF is from Fairchild Semiconductor with active product status and higher inventory availability (64,868 units).

Q: Can MMBT2222ALT1G be used as a substitute in through-hole applications?

A: No. MMBT2222ALT1G is a surface-mount device in SOT-23-3 package, incompatible with through-hole PCB designs. This part requires surface-mount assembly processes and modified PCB layouts. Use MMBT2222ALT1G only when transitioning to surface-mount technology.

Q: Does MMBT2222ALT1G have higher voltage capability than MPS2222RLRPG?

A: Yes. MMBT2222ALT1G has a 40 V collector-emitter breakdown voltage compared to 30 V for MPS2222RLRPG. This higher rating provides additional design margin in applications approaching the 30 V limit. All other electrical parameters remain equivalent.

Q: What is the power dissipation difference between MPS2222RLRPG and MMBT2222ALT1G?

A: MPS2222RLRPG is rated for 625 mW maximum power dissipation, while MMBT2222ALT1G is rated for 225 mW. This difference reflects the surface-mount package's reduced thermal capability. For applications requiring full 625 mW dissipation, use through-hole substitutes PN2222TF or PN2222TA.

Q: Are all substitute parts ROHS3 compliant?

A: PN2222TA and MMBT2222ALT1G are explicitly ROHS3 compliant. PN2222TF RoHS status is not specified in the provided data. Verify PN2222TF compliance with your supplier or design requirements documentation.

Q: What is the inventory status for each substitute?

A: PN2222TF has the highest inventory at 64,868 units. MMBT2222ALT1G has 725,400 units available. PN2222TA has 4,556 units with Last Time Buy status, indicating limited future availability. MPS2222RLRPG has 1,071 units as obsolete stock.
