Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC4116-GR-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Collector-emitter breakdown voltage must be greater than or equal to 60 V
• Maximum collector current must be greater than or equal to 150 mA
• Maximum power dissipation must be greater than or equal to 100 mW
• Transition frequency must be greater than or equal to 80 MHz
• DC current gain (hFE) characteristics must support intended circuit operation

Mechanical Compatibility Criteria:

• Package type must be SOT-323 or SC-70 (electrically and mechanically equivalent)
• Surface mount mounting type
• Moisture sensitivity level MSL 1 or better

Compliance Requirements:

• RoHS3 compliance required
• ECCN EAR99 classification

The identified substitute parts meet these criteria with the following considerations: 2SC4116-GR,LF operates at a reduced maximum voltage (50 V) compared to the original specification, while 2PC4081R,115 provides enhanced performance characteristics including higher power dissipation (200 mW) and transition frequency (100 MHz).

Parameter Comparison

Engineering Selection Recommendations

2SC4116-GR,LF (Direct Substitute - Toshiba Semiconductor and Storage)

This part is classified as a direct manufacturer equivalent with active product status. It maintains identical collector current (150 mA), power dissipation (100 mW), and transition frequency (80 MHz) specifications. The maximum collector-emitter breakdown voltage is reduced from 60 V to 50 V. This reduction is acceptable for applications where the circuit design operates below 50 V. The part carries ROHS3 compliance and MSL 1 rating, matching the original specification. Toshiba's active status ensures long-term availability and supply chain stability.

2PC4081R,115 (Similar Substitute - Nexperia USA Inc.)

This part is classified as a similar substitute with active product status and automotive-grade qualification (AEC-Q101). It maintains the 150 mA collector current and 50 V breakdown voltage. Enhanced specifications include 200 mW maximum power dissipation (versus 100 mW) and 100 MHz transition frequency (versus 80 MHz), providing performance margin for demanding applications. The maximum operating temperature matches the original at 150°C. Nexperia's automotive qualification and active status support applications requiring enhanced reliability and traceability. The higher Vce saturation (400mV versus 250mV) must be evaluated for saturation-dependent circuit designs.

Both substitute parts are ROHS3 compliant with EAR99 classification, matching the original part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can 2SC4116-GR,LF be used as a direct replacement for 2SC4116-GR-TP in all applications?

A: The 2SC4116-GR,LF is electrically compatible for applications operating at collector-emitter voltages of 50 V or below. The reduced maximum voltage rating (50 V versus 60 V) must be verified against circuit design specifications. All other electrical parameters—collector current, power dissipation, and transition frequency—are identical. Package compatibility is confirmed (SOT-323/SC-70).

Q: What is the difference between 2SC4116-GR,LF and 2PC4081R,115?

A: Both parts share the same 50 V breakdown voltage and 150 mA collector current. The 2PC4081R,115 provides enhanced power dissipation (200 mW versus 100 mW) and higher transition frequency (100 MHz versus 80 MHz). The 2PC4081R,115 carries automotive-grade qualification (AEC-Q101) and operates at the same maximum temperature (150°C). The 2SC4116-GR,LF has a lower maximum operating temperature (125°C). Selection depends on thermal requirements and automotive qualification needs.

Q: Are the SOT-323 and SC-70 packages interchangeable?

A: SOT-323 and SC-70 are electrically and mechanically equivalent package designations for the same physical form factor. Both packages are used interchangeably in surface mount applications. Pin configuration and footprint requirements are identical.

Q: Why is the 2SC4116-GR-TP classified as obsolete?

A: The 2SC4116-GR-TP is listed as obsolete by the original manufacturer (Micro Commercial Co). The identified substitute parts from Toshiba and Nexperia provide active, supported alternatives with equivalent or enhanced electrical characteristics.

Q: What compliance certifications apply to these substitute parts?

A: All three parts (2SC4116-GR-TP, 2SC4116-GR,LF, and 2PC4081R,115) are ROHS3 compliant and classified under ECCN EAR99. The 2PC4081R,115 additionally carries AEC-Q101 automotive qualification. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: How do the DC current gain (hFE) specifications differ among these parts?

A: The 2SC4116-GR-TP specifies hFE minimum of 200 @ 1mA, 6V. The 2SC4116-GR,LF specifies hFE minimum of 70 @ 2mA, 6V (measured at different bias conditions). The 2PC4081R,115 specifies hFE minimum of 180 @ 1mA, 6V. Circuit designs dependent on specific hFE values must account for these variations in bias point and measurement conditions.

Q: Can 2PC4081R,115 be used in applications requiring the full 60 V rating of the original part?

A: No. The 2PC4081R,115 has a maximum collector-emitter breakdown voltage of 50 V. Applications requiring 60 V operation must use the original 2SC4116-GR-TP or identify alternative parts with 60 V or higher ratings.
