Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC2235-Y(T6CANOFM is determined by electrical parameter equivalence across the following critical specifications:

Electrical Equivalence Criteria:

• Transistor type (NPN)
• Maximum collector current (800mA)
• Collector-emitter breakdown voltage (120V)
• Saturation voltage characteristics (1V @ 50mA, 500mA)
• Collector cutoff current (100nA)
• Transition frequency (120MHz)
• Operating temperature range (150°C TJ)

Mechanical Compatibility Considerations:

• Package type and pinout configuration
• Mounting methodology (through hole versus surface mount)
• Physical form factor

The 2SC2881-Y(TE12L,ZC meets the electrical parameter requirements for substitution. However, this part differs in mounting type (surface mount versus through hole) and maximum power dissipation (500mW versus 900mW), requiring circuit-level evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

2SC2881-Y(TE12L,ZC Suitability:

The 2SC2881-Y(TE12L,ZC is electrically equivalent to the 2SC2235-Y(T6CANOFM across all primary electrical parameters: collector current, breakdown voltage, saturation characteristics, cutoff current, and transition frequency. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Considerations for Implementation:

The 2SC2881-Y(TE12L,ZC operates at a reduced maximum power dissipation of 500mW compared to the original part's 900mW rating. Applications requiring thermal dissipation near or exceeding 500mW require thermal analysis to confirm adequate heat management within the PW-MINI package.

The DC current gain (hFE) of the substitute is higher (120 minimum versus 80 minimum), which may affect biasing calculations in circuits with fixed base resistor networks. Circuits employing feedback biasing or current-source biasing are less sensitive to this variation.

The substitute part utilizes surface mount packaging (TO-243AA, PW-MINI) rather than through-hole mounting. PCB redesign is required for mechanical and electrical integration.

The 2SC2881-Y(TE12L,ZC carries RoHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2SC2881-Y(TE12L,ZC directly replace the 2SC2235-Y(T6CANOFM in existing through-hole PCB designs?

A: No. The substitute part uses surface mount packaging (TO-243AA, PW-MINI) while the original uses through-hole TO-92-3 Long Body. PCB redesign is required. Mechanical mounting and electrical connection methods differ fundamentally between these package types.

Q: Are the electrical characteristics identical between these parts?

A: The primary electrical parameters are equivalent: collector current (800mA), breakdown voltage (120V), saturation voltage, cutoff current, and transition frequency (120MHz) are identical. The DC current gain (hFE) is higher in the substitute (120 versus 80 minimum), and maximum power dissipation is lower (500mW versus 900mW).

Q: What is the impact of the lower power rating on the substitute part?

A: Applications dissipating power below 500mW experience no impact. Circuits designed for the original 900mW rating require thermal analysis. If the original design operated near 900mW, the substitute may require additional heat management or circuit modification to maintain acceptable junction temperatures.

Q: How does the higher DC current gain affect circuit operation?

A: In circuits with fixed base resistor biasing, higher hFE results in lower base current requirements for the same collector current. Circuits employing emitter feedback or current-source biasing automatically compensate for hFE variation and are unaffected. Fixed-bias circuits may require base resistor recalculation.

Q: Is the 2SC2881-Y(TE12L,ZC suitable for new designs?

A: Yes. The substitute part is in active production status with RoHS3 compliance and REACH unaffected status, making it suitable for new product development. Surface mount packaging aligns with modern manufacturing processes.

Q: What certifications and compliance standards apply to the substitute part?

A: The 2SC2881-Y(TE12L,ZC is RoHS3 compliant and REACH unaffected. Both parts carry EAR99 export classification and are assigned to HTSUS commodity codes for semiconductor transistors.
