Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2SC4617T1 are identified based on strict electrical and mechanical parameter compatibility. The primary substitution criteria are:

Electrical Parameters (Must Match or Exceed):

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): ≥ 50 V
• Current - Collector (Ic) (Max): ≥ 100 mA
• Power - Max: ≥ 125 mW
• Frequency - Transition: ≥ 180 MHz
• DC Current Gain (hFE) (Min): ≥ 120 @ 1mA, 6V
• Vce Saturation (Max): ≤ 400mV @ 5mA, 60mA
• Current - Collector Cutoff (Max): ≤ 500nA

Mechanical Parameters:

• Mounting Type: Surface Mount
• Package / Case: SC-75 (SOT-416) or compatible footprint

Substitutes are classified into two categories: parametric equivalents (identical electrical specifications) and similar parts (enhanced electrical specifications with compatible footprints).

Engineering Selection Recommendations

S2SC4617G (Parametric Equivalent - Recommended Primary Substitute)

The S2SC4617G is a direct parametric equivalent manufactured by onsemi with identical electrical specifications to the 2SC4617T1. This part maintains the same SC-75 (SOT-416) package footprint, enabling direct board-level substitution without layout modifications. The S2SC4617G is classified as active product status, ensuring long-term availability and supply chain stability. This part is ROHS3 compliant, addressing environmental and regulatory requirements that the obsolete 2SC4617T1 does not meet. The S2SC4617G is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

2SC4617-R-TP (Similar Part - Alternative for Enhanced Performance)

The 2SC4617-R-TP manufactured by Micro Commercial Co provides enhanced electrical specifications with 150 mA maximum collector current and 150 mW maximum power dissipation, compared to 100 mA and 125 mW for the 2SC4617T1. This part maintains the 50 V breakdown voltage, 180 MHz transition frequency, and identical DC current gain specifications. The 2SC4617-R-TP is classified as active product status. The package footprint differs (SOT-523 versus SC-75/SOT-416), requiring PCB layout evaluation for compatibility. This part is suitable for applications requiring higher current handling or thermal margin. Operating temperature range extends to -55°C, providing broader environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the S2SC4617G be used as a direct replacement for the 2SC4617T1?

A: Yes. The S2SC4617G is a parametric equivalent with identical electrical specifications and the same SC-75 (SOT-416) package footprint. Direct board-level substitution is possible without circuit modifications or layout changes.

Q: What is the primary advantage of using S2SC4617G over the obsolete 2SC4617T1?

A: The S2SC4617G is active product status with confirmed long-term availability. It is ROHS3 compliant, meeting current environmental and regulatory standards. The 2SC4617T1 is obsolete and RoHS non-compliant.

Q: Can the 2SC4617-R-TP be used in place of the 2SC4617T1?

A: The 2SC4617-R-TP meets all electrical parameter requirements with enhanced current and power ratings. However, the package footprint differs (SOT-523 versus SC-75/SOT-416). PCB layout compatibility must be evaluated before substitution. This part is suitable for designs requiring higher current capacity or thermal margin.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are collector-emitter breakdown voltage (50 V minimum), maximum collector current (100 mA minimum), maximum power dissipation (125 mW minimum), transition frequency (180 MHz minimum), and DC current gain (120 minimum @ 1mA, 6V). All substitute parts must meet or exceed these specifications.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The S2SC4617G maintains the SC-75 (SOT-416) package, enabling direct substitution. The 2SC4617-R-TP uses SOT-523 packaging, which has a different footprint. Verify PCB pad layout compatibility before selecting the 2SC4617-R-TP.

Q: What is the difference between the S2SC4617G packaging options?

A: The S2SC4617G is supplied in Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly. The 2SC4617-R-TP is supplied in Bulk packaging.

Q: Does the operating temperature range affect substitution decisions?

A: The S2SC4617G specifies 150°C maximum junction temperature. The 2SC4617-R-TP specifies -55°C to 150°C operating range. For applications with extreme temperature requirements, the 2SC4617-R-TP provides broader environmental coverage. The 2SC4617T1 does not specify operating temperature limits.

Q: Are there compliance differences between the substitute parts?

A: Yes. The S2SC4617G is ROHS3 compliant. The 2SC4617T1 is RoHS non-compliant. The 2SC4617-R-TP compliance status is not specified in the provided data. Both substitute parts are REACH unaffected and classified as EAR99 for export control purposes.
