Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC4783-T1-A is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the SC-75 surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Transistor Type: NPN polarity must be maintained to preserve circuit functionality and biasing requirements.

Compliance Standards: ROHS3 compliance and EAR99 export classification must be matched to satisfy regulatory and supply chain requirements.

Moisture Sensitivity: MSL rating of 1 (Unlimited) ensures equivalent handling and storage conditions.

Electrical Characteristics: While specific electrical parameters for the 2SC4783-T1-A were not provided in the input, substitute parts must operate within the SC-75 package thermal and electrical envelope.

The S2SC4617G meets all substitution criteria through identical package designation, NPN configuration, ROHS3 compliance, and MSL rating.

Parameter Comparison

Engineering Selection Recommendations

The S2SC4617G serves as a direct substitute for the obsolete 2SC4783-T1-A based on the following engineering criteria:

Package Equivalence: Both components utilize the SC-75 surface mount package, ensuring pin-compatible placement and soldering processes without PCB redesign.

Regulatory Compliance: The S2SC4617G maintains ROHS3 compliance and EAR99 export classification, satisfying the same regulatory framework as the original part.

Moisture Handling: Identical MSL rating of 1 (Unlimited) ensures equivalent storage, handling, and assembly requirements throughout the supply chain.

Active Product Status: The S2SC4617G is classified as an active product with documented availability, providing long-term supply continuity compared to the obsolete 2SC4783-T1-A.

Electrical Performance: The S2SC4617G provides specified electrical characteristics (100 mA collector current, 50 V breakdown voltage, 125 mW power dissipation, 180 MHz transition frequency) suitable for general-purpose NPN switching and amplification applications within the SC-75 package thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can the S2SC4617G be used as a direct replacement for the 2SC4783-T1-A without circuit modification?

A: Yes. Both components share identical package designation (SC-75), NPN polarity, surface mount configuration, and compliance certifications. No circuit redesign is required for package-level substitution.

Q: What is the significance of the SC-75 and SOT-416 package designation for the S2SC4617G?

A: SC-75 and SOT-416 refer to the same physical package outline. SOT-416 is the standardized designation, while SC-75 is the manufacturer-specific identifier. Both designations describe an identical three-lead surface mount package.

Q: Are there any differences in moisture sensitivity handling between these parts?

A: No. Both the 2SC4783-T1-A and S2SC4617G carry MSL rating 1 (Unlimited), indicating identical moisture sensitivity classification and requiring the same storage and handling protocols.

Q: Why is the 2SC4783-T1-A classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Renesas Electronics Corporation. The S2SC4617G, classified as active, provides ongoing availability and manufacturing support.

Q: What packaging format is available for the S2SC4617G?

A: The S2SC4617G is supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly operations.

Q: Are the electrical specifications of the S2SC4617G suitable for all applications using the 2SC4783-T1-A?

A: Electrical suitability depends on specific circuit requirements. The S2SC4617G specifications (100 mA Ic max, 50 V Vce breakdown, 125 mW power, 180 MHz fT) define the operational envelope. Circuit designers must verify these parameters against application requirements.

Q: Do both parts share the same export classification?

A: Yes. Both the 2SC4783-T1-A and S2SC4617G are classified under ECCN EAR99, ensuring equivalent export compliance requirements.
