Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC4935-Y,Q(J is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown (Max) must be equal to or greater than 50 V
• Current - Collector (Ic) (Max) must be equal to or greater than 3 A
• Operating temperature range must support 150°C (TJ)

Mechanical Compatibility Criteria:

• Package type and mounting configuration must be compatible with the application's PCB layout and thermal management requirements

The 2SC5886A(T6L1,NQ) meets the electrical requirements for substitution. However, this part differs in mounting type (surface mount versus through hole) and package configuration (TO-252-3, DPAK versus TO-220-3). This difference requires evaluation based on the specific application's mechanical constraints and PCB design.

Engineering Selection Recommendations

2SC5886A(T6L1,NQ) as a Substitute:

The 2SC5886A(T6L1,NQ) is classified as active and is RoHS3 compliant, providing long-term supply chain availability compared to the obsolete 2SC4935-Y,Q(J. This part exceeds the electrical requirements of the original component, with a maximum collector current of 5 A versus 3 A and improved DC current gain characteristics (400 versus 70 at 500mA, 2V).

The primary consideration for substitution is the change in mounting type and package configuration. The 2SC5886A(T6L1,NQ) uses surface-mount technology (TO-252-3, DPAK) rather than through-hole mounting (TO-220-3). This substitution is viable only when the PCB design can accommodate surface-mount components and when thermal management requirements are compatible with the reduced power rating (1 W versus 2 W).

The lower maximum power dissipation of the 2SC5886A(T6L1,NQ) requires verification that the application's thermal load does not exceed 1 W under operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 2SC5886A(T6L1,NQ) directly replace the 2SC4935-Y,Q(J in an existing design?

A: Electrical substitution is possible because the 2SC5886A(T6L1,NQ) meets or exceeds the voltage and current specifications. However, mechanical substitution requires PCB redesign due to the change from through-hole (TO-220-3) to surface-mount (TO-252-3, DPAK) packaging. Direct socket replacement is not possible without PCB modification.

Q: What are the key electrical differences between these parts?

A: Both parts operate at 50 V maximum collector-emitter breakdown voltage and 150°C maximum junction temperature. The 2SC5886A(T6L1,NQ) supports higher collector current (5 A versus 3 A) and exhibits superior DC current gain (400 versus 70 at 500mA, 2V). The 2SC4935-Y,Q(J supports higher power dissipation (2 W versus 1 W).

Q: Is the 2SC5886A(T6L1,NQ) suitable for high-power applications?

A: The 2SC5886A(T6L1,NQ) has a maximum power rating of 1 W, which is lower than the 2SC4935-Y,Q(J (2 W). Applications requiring sustained power dissipation above 1 W must verify thermal performance or consider alternative components.

Q: What is the significance of the product status difference?

A: The 2SC4935-Y,Q(J is obsolete, indicating discontinued manufacturing and limited future availability. The 2SC5886A(T6L1,NQ) is active and RoHS3 compliant, ensuring continued supply and compliance with current environmental regulations.

Q: Are there moisture sensitivity concerns with either part?

A: Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
