Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SC2881-O-TP are qualified based on the following criteria:

Electrical Compatibility Requirements:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown rating must be ≥ 120 V
• Operating temperature range must support 150°C (TJ)
• RoHS3 compliance required

Mechanical Compatibility Requirements:

• Package / Case must be TO-243AA
• Mounting type must be Surface Mount
• Supplier device package must be compatible with SOT-89 footprint

Performance Considerations:

• Current - Collector (Ic) rating of 700 mA is acceptable as a substitute for 800 mA applications where the lower rating does not exceed circuit requirements
• Power dissipation of 500 mW is acceptable for applications not requiring the full 1 W capability
• Frequency - Transition of 220 MHz exceeds the 120 MHz requirement and provides enhanced high-frequency performance

The substitute parts 2SCR372P5T100Q and 2SCR372P5T100R meet all electrical and mechanical compatibility criteria.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (2SC2881-O-TP): The 2SC2881-O-TP is the specified component and remains the first choice when available. It provides 800 mA collector current capability and 1 W power dissipation. The device is Active product status with full RoHS3 and REACH compliance.

Substitute Selection (2SCR372P5T100Q or 2SCR372P5T100R): The Rohm Semiconductor parts 2SCR372P5T100Q and 2SCR372P5T100R are functionally equivalent substitutes for applications where the 2SC2881-O-TP is unavailable. Both parts are Active product status with RoHS3 compliance and REACH Unaffected designation.

Substitution Constraints:

• The 700 mA maximum collector current of the substitute parts limits their use to circuits designed for ≤ 700 mA operation
• The 500 mW power dissipation rating requires thermal design verification for applications approaching 500 mW
• The improved DC current gain (120 vs. 80) and lower saturation voltage (300 mV vs. 1 V) of the substitute parts provide enhanced performance characteristics

Packaging and Inventory:

• 2SC2881-O-TP: 821 Pcs available in Tape & Reel packaging
• 2SCR372P5T100Q: 10,300 Pcs available in Cut Tape & Digi-Reel packaging
• 2SCR372P5T100R: 3,400 Pcs available in Cut Tape & Digi-Reel packaging

Frequently Asked Questions (FAQ)

Q: Can 2SCR372P5T100Q and 2SCR372P5T100R be used interchangeably with 2SC2881-O-TP?

A: Yes, within the constraints of the 700 mA maximum collector current rating. Both substitute parts share identical electrical specifications and the same TO-243AA package footprint. The primary limitation is the reduced current capacity, which requires circuit design verification.

Q: What is the difference between 2SCR372P5T100Q and 2SCR372P5T100R?

A: Both parts are electrically and mechanically identical. The difference is in the packaging format: 2SCR372P5T100Q is supplied in Cut Tape & Digi-Reel format with 10,300 units in stock, while 2SCR372P5T100R is also supplied in Cut Tape & Digi-Reel format with 3,400 units in stock. Selection between these two is based on inventory availability and packaging requirements.

Q: Are there any thermal considerations when substituting with the Rohm parts?

A: The substitute parts have a maximum power dissipation of 500 mW compared to 1 W for the 2SC2881-O-TP. Thermal design must account for this reduced power rating. The improved saturation voltage (300 mV vs. 1 V) of the substitute parts reduces power dissipation in saturation mode, partially offsetting the lower power rating.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both 2SCR372P5T100Q and 2SCR372P5T100R are RoHS3 compliant and REACH Unaffected, matching the compliance profile of the 2SC2881-O-TP.

Q: What is the impact of the higher transition frequency in the substitute parts?

A: The substitute parts operate at 220 MHz transition frequency compared to 120 MHz for the 2SC2881-O-TP. This higher frequency capability provides improved performance in high-frequency applications and does not create compatibility issues in circuits designed for the lower frequency specification.

Q: Are the packaging formats compatible with existing assembly equipment?

A: All three parts use the TO-243AA package and surface mount technology. The 2SC2881-O-TP is supplied in Tape & Reel format, while the substitute parts are supplied in Cut Tape & Digi-Reel format. Assembly equipment compatibility depends on the specific feeder configuration; both formats are standard in surface mount assembly processes.
