2N6288G Equivalent & Substitute Parts

Part Overview

The 2N6288G is an NPN bipolar junction transistor manufactured by onsemi, housed in a TO-220-3 package for through-hole mounting. This device is rated for 30 V collector-emitter breakdown voltage, 7 A maximum collector current, and 40 W maximum power dissipation. The 2N6288G operates across a temperature range of -65°C to 150°C and features a 4 MHz transition frequency.

The 2N6288G is currently in Last Time Buy status, indicating that onsemi has discontinued or will discontinue production. This product status necessitates identification of equivalent and substitute parts to ensure design continuity and procurement availability for applications requiring NPN transistor functionality in the TO-220 package.

Substitute Part Grouping Explanation

Substitution of the 2N6288G is determined by electrical and mechanical compatibility within the NPN bipolar transistor category. The primary substitution criteria are:

Electrical Compatibility Requirements:

Transistor type must be NPN
Collector-emitter breakdown voltage must equal or exceed the application requirement (30 V minimum for 2N6288G)
Maximum collector current must equal or exceed the application requirement (7 A minimum for 2N6288G)
Maximum power dissipation must equal or exceed the application requirement (40 W minimum for 2N6288G)
Operating temperature range must encompass the application operating conditions

Mechanical Compatibility Requirements:

Package type must be TO-220-3 or compatible TO-220 variant
Mounting type must be through-hole
Pin configuration must be compatible with existing PCB layouts

Compliance Requirements:

RoHS3 compliance status must be maintained
REACH status must be unaffected

The substitute parts listed below satisfy these criteria with electrical ratings that meet or exceed the 2N6288G specifications, ensuring functional equivalence in applications designed for the original part.

Engineering Selection Recommendations

MJE3055TG (onsemi): The MJE3055TG is a manufacturer-recommended substitute produced by onsemi, the original manufacturer of the 2N6288G. This part exceeds the 2N6288G specifications in collector-emitter breakdown voltage (60 V vs. 30 V), maximum collector current (10 A vs. 7 A), and maximum power dissipation (75 W vs. 40 W). The MJE3055TG maintains ROHS3 compliance and active product status, ensuring long-term availability. The transition frequency is lower (2 MHz vs. 4 MHz), which may be acceptable for applications not requiring high-frequency switching performance. This substitute is suitable for applications where higher voltage and current ratings provide design margin.

TIP41C-BP (Micro Commercial Co): The TIP41C-BP is a similar substitute with higher collector-emitter breakdown voltage (100 V) but lower maximum power dissipation (2 W vs. 40 W). The maximum collector current is 6 A, which is below the 2N6288G rating of 7 A. The TIP41C-BP maintains ROHS3 compliance and active product status. This substitute is suitable only for applications where power dissipation requirements are significantly lower than the 2N6288G design specification and collector current does not exceed 6 A. The TO-220AB package variant is mechanically compatible with TO-220-3 layouts.

Selection between MJE3055TG and TIP41C-BP depends on application power dissipation and current requirements. For applications requiring the full 40 W power capability and 7 A collector current of the 2N6288G, the MJE3055TG is the appropriate substitute. For lower-power applications, the TIP41C-BP may be considered if collector current remains below 6 A.

Frequently Asked Questions (FAQ)

Q: Can the MJE3055TG directly replace the 2N6288G in all applications?

A: The MJE3055TG has higher electrical ratings (60 V breakdown voltage, 10 A collector current, 75 W power) than the 2N6288G (30 V, 7 A, 40 W), making it electrically compatible for applications designed for the 2N6288G. The TO-220-3 package is identical, ensuring mechanical compatibility. However, the transition frequency is lower (2 MHz vs. 4 MHz), which may affect high-frequency switching applications. Verify that the lower transition frequency does not impact circuit performance.

Q: Is the TIP41C-BP suitable as a substitute for the 2N6288G?

A: The TIP41C-BP has a maximum power dissipation of 2 W, which is significantly lower than the 2N6288G specification of 40 W. This part is suitable only for applications where actual power dissipation is well below 2 W. The maximum collector current of 6 A is also below the 2N6288G rating of 7 A. Use the TIP41C-BP only in applications with reduced power and current requirements.

Q: Are the TO-220-3 and TO-220AB packages interchangeable?

A: The TO-220-3 and TO-220AB packages are mechanically compatible for through-hole PCB mounting. Both packages have three leads with identical pin spacing and can be mounted in the same footprint. Verify that the specific PCB layout accommodates the package variant dimensions.

Q: What is the significance of the 2N6288G Last Time Buy status?

A: Last Time Buy status indicates that onsemi has ceased or will cease production of the 2N6288G. Existing inventory may be available for a limited time, but long-term procurement is not guaranteed. Transition to an active substitute part such as the MJE3055TG is recommended for new designs and ongoing production requirements.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes, both the MJE3055TG and TIP41C-BP are ROHS3 compliant, matching the compliance status of the 2N6288G. All three parts are also REACH unaffected, ensuring regulatory compliance across applications.

Q: How do I determine which substitute is appropriate for my application?

A: Compare your application's actual power dissipation, collector current, and collector-emitter voltage requirements against the specifications of each substitute. If your application requires up to 40 W power dissipation and 7 A collector current at voltages up to 30 V, the MJE3055TG is the appropriate substitute. If your application requires significantly lower power dissipation (below 2 W) and collector current (below 6 A), the TIP41C-BP may be considered. Ensure that the transition frequency of the selected substitute meets your circuit's switching speed requirements.
