Current - Collector (Ic) (Max) must be ≥ 3 A
Vce Saturation (Max) must be ≤ 290 mV @ 100 mA, 2 A
DC Current Gain (hFE) (Min) must be ≥ 200 @ 100 mA, 2 V
Current - Collector Cutoff (Max) must be ≤ 1 µA

Engineering Selection Recommendations

Direct Substitutes (Preferred for Obsolete Part Replacement):

The 2SC5964-TD-E and 2SC5964-TD-H are direct substitutes for the 2SC5964-S-TD-E. Both parts are manufactured by onsemi with active product status, ensuring long-term availability. These parts maintain identical electrical specifications including 50 V breakdown voltage, 3 A collector current, 290 mV saturation voltage, and 380 MHz transition frequency. The primary difference is packaging format: 2SC5964-TD-E is supplied in Cut Tape (CT) & Digi-Reel format, while 2SC5964-TD-H is supplied in Tape & Reel (TR) format. Both are ROHS3 compliant with MSL 1 rating. Selection between these two should be based on procurement and assembly requirements.

Functionally Equivalent Alternatives:

The 2SD1624T-TD-E is functionally equivalent with the same 50 V / 3 A ratings and identical saturation voltage specification. However, this part operates at 150 MHz transition frequency (lower than the 380 MHz of the main part) and has reduced maximum power dissipation of 500 mW. This part is suitable for applications where lower frequency operation is acceptable and power dissipation is not a limiting factor.

The 2SC5994-TD-E operates at higher transition frequency (420 MHz) but is rated for 2 A maximum collector current instead of 3 A. This part is suitable for applications where the 3 A rating is not required and higher frequency performance is beneficial.

The PBSS4350X,135 from Nexperia USA Inc. provides 3 A / 50 V capability with automotive-grade qualification (AEC-Q100). This part operates at 100 MHz transition frequency and has higher saturation voltage (370 mV). Selection of this part is appropriate for automotive applications requiring AEC-Q100 qualification.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use 2SC5964-TD-E as a direct replacement for 2SC5964-S-TD-E?

A: Yes. The 2SC5964-TD-E is a direct substitute with identical electrical specifications. The primary difference is packaging format (Cut Tape & Digi-Reel versus the original packaging). Both parts are manufactured by onsemi, maintain the same TO-243AA footprint, and are ROHS3 compliant.

Q: What is the difference between 2SC5964-TD-E and 2SC5964-TD-H?

A: Both parts have identical electrical specifications. The difference is in packaging format: 2SC5964-TD-E is supplied in Cut Tape (CT) & Digi-Reel format, while 2SC5964-TD-H is supplied in Tape & Reel (TR) format. Selection depends on assembly line requirements and procurement preferences.

Q: Can I substitute 2SD1624T-TD-E for the 2SC5964-S-TD-E?

A: The 2SD1624T-TD-E is functionally equivalent for voltage and current ratings but operates at lower transition frequency (150 MHz versus 380 MHz) and has reduced power dissipation (500 mW versus 1.3 W). Additionally, saturation voltage is higher (500 mV versus 290 mV). This part is suitable only if your application does not require the higher frequency performance or power handling capability.

Q: Is the 2SC5994-TD-E a suitable substitute?

A: The 2SC5994-TD-E is a similar substitute with higher transition frequency (420 MHz) but lower maximum collector current (2 A versus 3 A). This part is suitable only if your application does not require the full 3 A collector current rating.

Q: What is the advantage of PBSS4350X,135 over other substitutes?

A: The PBSS4350X,135 is an automotive-grade part with AEC-Q100 qualification. It maintains the 3 A / 50 V rating and is suitable for automotive applications. However, it operates at lower transition frequency (100 MHz) and has higher saturation voltage (370 mV). Selection of this part is appropriate only for automotive applications requiring AEC-Q100 qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and have Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Q: Do all substitute parts use the same TO-243AA package?

A: Yes. All substitute parts use the TO-243AA package with surface mount mounting type, ensuring mechanical compatibility with the original design. No PCB layout modifications are required.

Q: Which substitute should I choose for a new design?

A: For new designs, select either 2SC5964-TD-E or 2SC5964-TD-H based on your procurement and assembly requirements. Both are active products from onsemi with identical electrical specifications and long-term availability. If automotive qualification is required, select PBSS4350X,135.

Q: Can I mix different substitute parts in the same production batch?

A: All listed substitute parts are electrically compatible and mechanically interchangeable. However, mixing different part numbers in the same production batch may complicate traceability and quality control. Standardization on a single substitute part number is recommended for production consistency.
