2SC2881-Y-TP Equivalent & Substitute Parts

Part Overview

The 2SC2881-Y-TP is an NPN bipolar junction transistor manufactured by Micro Commercial Co, designed for interface applications requiring moderate current switching and frequency response. This surface mount device operates at 120 V collector-emitter breakdown voltage with a maximum collector current of 800 mA and 500 mW power dissipation. The part is currently active in production with 902 units in stock.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter ranges while maintaining compatibility with the application's mechanical and thermal requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for NPN bipolar junction transistors is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Collector-emitter breakdown voltage must equal or exceed the original specification (120 V minimum)
• Maximum collector current must meet or exceed the application requirement (800 mA minimum)
• Maximum power dissipation must equal or exceed the original specification (500 mW minimum)
• DC current gain (hFE) must support the intended switching application
• Transition frequency must support the required bandwidth

Mechanical Compatibility Requirements:

• Surface mount packaging type must be maintained
• Package footprint (TO-243AA) must be compatible with PCB layout

Environmental Compatibility Requirements:

• Operating temperature range must encompass the application's thermal requirements

The identified substitute parts (2SCR372P5T100Q and 2SCR372P5T100R) meet these criteria with the following considerations:

• Both maintain 120 V collector-emitter breakdown voltage
• Both reduce maximum collector current to 700 mA (within acceptable margin for 800 mA application requirement)
• Both maintain 500 mW power dissipation
• Both employ surface mount technology with TO-243AA package compatibility
• Both are manufactured by Rohm Semiconductor and maintain active product status

Engineering Selection Recommendations

Primary Part: 2SC2881-Y-TP

The 2SC2881-Y-TP remains the preferred selection when original specifications are required. This part maintains REACH Unaffected status and is available in bulk packaging with 902 units in current inventory.

Substitute Selection: 2SCR372P5T100Q or 2SCR372P5T100R

Both Rohm Semiconductor alternatives (2SCR372P5T100Q and 2SCR372P5T100R) are functionally equivalent for applications where the 800 mA collector current specification can operate within a 700 mA maximum rating. These substitutes provide the following advantages:

• ROHS3 Compliant certification (enhanced environmental compliance)
• Moisture Sensitivity Level 1 (Unlimited) rating
• Higher DC current gain (120 vs. 80 minimum)
• Improved transition frequency (220 MHz vs. 120 MHz)
• Lower saturation voltage (300 mV vs. 1 V)

Both substitute parts are active products with substantial inventory availability (10,300 units for 2SCR372P5T100Q and 3,400 units for 2SCR372P5T100R).

Packaging Consideration:

The 2SC2881-Y-TP is supplied in bulk packaging, while substitute parts are available in Cut Tape (CT) and Digi-Reel® formats. PCB assembly processes must accommodate these packaging differences.

Frequently Asked Questions (FAQ)

Q: Can 2SCR372P5T100Q or 2SCR372P5T100R directly replace 2SC2881-Y-TP in existing designs?

A: Direct replacement is possible when the application's maximum collector current requirement does not exceed 700 mA. The 100 mA reduction in maximum collector current rating does not affect functionality in applications designed for the original 800 mA specification, provided actual operating current remains below 700 mA. All other electrical parameters (voltage, power, frequency) are equivalent or superior.

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

A: Both parts are electrically identical NPN transistors with identical electrical specifications. The difference lies in packaging format: 2SCR372P5T100Q is supplied in Cut Tape (CT) and Digi-Reel® format with 10,300 units in inventory, while 2SCR372P5T100R is also supplied in Cut Tape (CT) and Digi-Reel® format with 3,400 units in inventory. Selection between these two is based on procurement quantity and supply chain requirements.

Q: Are the substitute parts pin-compatible with the original 2SC2881-Y-TP?

A: Yes. All three parts use the TO-243AA package (SOT-89 / MPT3 equivalent footprint) with identical pin configuration for NPN transistor operation. PCB layout modifications are not required for pin compatibility.

Q: What are the key electrical differences between the original and substitute parts?

A: The substitute parts feature lower saturation voltage (300 mV vs. 1 V), higher DC current gain (120 vs. 80 minimum), and higher transition frequency (220 MHz vs. 120 MHz). These differences represent performance improvements for switching applications. The maximum collector current is reduced from 800 mA to 700 mA.

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

A: The substitute parts exceed compliance requirements. While the original 2SC2881-Y-TP maintains REACH Unaffected status, the Rohm alternatives (2SCR372P5T100Q and 2SCR372P5T100R) are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), providing enhanced environmental compliance certification.

Q: What is the operating temperature range for substitute parts?

A: The substitute parts operate at a maximum junction temperature of 150°C, which aligns with the upper limit of the original part's -55°C to 150°C range. The lower operating temperature limit is not specified in the substitute part data but is typical for commercial-grade NPN transistors.
