Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC45620RL is determined by electrical and mechanical compatibility within the following parameters:

Critical Substitution Parameters:

• Transistor polarity (NPN type required)
• Collector-emitter breakdown voltage rating (minimum 50V required)
• Maximum collector current rating (minimum 50mA required)
• Maximum power dissipation (minimum 150mW required)
• Transition frequency (minimum 250MHz required)
• Surface mount package compatibility (SC-70 / SOT-323)
• Operating temperature range (minimum 150°C TJ required)
• Moisture sensitivity level (MSL 1 or equivalent)

The 2SC4097T106Q manufactured by Rohm Semiconductor satisfies substitution criteria based on the following alignment:

The 2SC4097T106Q exceeds the electrical specifications of the 2SC45620RL in collector current (500mA vs. 50mA), power dissipation (200mW vs. 150mW), and transition frequency (250MHz, equal). The collector-emitter breakdown voltage of 32V is lower than the 50V specification of the 2SC45620RL; however, this parameter represents a design constraint that must be evaluated within the specific application circuit. Both devices share identical surface mount packaging (SC-70 / SOT-323), operating temperature range (150°C TJ), and moisture sensitivity classification (MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 2SC45620RL is classified as obsolete, while the 2SC4097T106Q is active and in production. The 2SC4097T106Q maintains continuous manufacturing support and availability through authorized distributors.

Compliance and Certification: The 2SC4097T106Q is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in restricted substance directives. Both devices carry identical ECCN (EAR99) and HTSUS (8541.21.0075) classifications.

Electrical Parameter Variance: The 2SC4097T106Q provides higher collector current capacity (500mA vs. 50mA) and increased power dissipation capability (200mW vs. 150mW), offering design margin in applications requiring higher current handling. The transition frequency remains equivalent at 250MHz.

The reduced collector-emitter breakdown voltage (32V vs. 50V) in the 2SC4097T106Q represents a specification reduction that requires circuit-level evaluation. Applications operating at voltages exceeding 32V require alternative substitutes or retention of the original 2SC45620RL specification.

Inventory and Supply Chain: The 2SC4097T106Q maintains substantial inventory availability (90,200 pieces in stock) compared to the 2SC45620RL (1,126 pieces), supporting long-term production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2SC4097T106Q directly replace the 2SC45620RL in all applications?

A: Direct replacement is contingent upon circuit voltage specifications. The 2SC4097T106Q operates at a maximum collector-emitter breakdown voltage of 32V, compared to 50V for the 2SC45620RL. Applications designed for 50V operation require verification that actual operating voltages remain below 32V. The 2SC4097T106Q is suitable for applications operating at 32V or lower.

Q: Are the package dimensions identical between these devices?

A: Both devices utilize the SC-70 (SOT-323) surface mount package. Physical footprint and pin configuration are compatible, permitting direct PCB layout substitution without modification.

Q: What is the significance of the different DC current gain (hFE) specifications?

A: The 2SC45620RL specifies hFE minimum of 250 at 2mA and 10V, while the 2SC4097T106Q specifies hFE minimum of 120 at 10mA and 3V. These measurements occur at different bias points. Circuit designs relying on specific gain characteristics at particular operating points require evaluation of the substitute device's gain profile at the intended bias conditions.

Q: Does the higher collector current rating of the 2SC4097T106Q affect compatibility?

A: Higher current ratings provide design margin and do not prevent substitution. Applications designed for 50mA operation function within the 500mA capability of the 2SC4097T106Q. The substitute device accommodates the original design current requirements with additional capacity.

Q: What moisture sensitivity considerations apply to these devices?

A: Both devices carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.

Q: Is the 2SC4097T106Q suitable for high-frequency applications?

A: Both devices specify identical transition frequency of 250MHz, supporting equivalent high-frequency performance in switching and amplification circuits operating within this frequency range.
