Substitute Part Grouping Explanation

Substitution of the 2SC58630QL is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

Transistor type must be NPN
Collector-emitter breakdown voltage must be equal to or greater than 300 V
Maximum collector current must be equal to or greater than 70 mA
Maximum power dissipation must be equal to or greater than 200 mW
Transition frequency must support the intended application bandwidth

Mechanical Compatibility Criteria:

Mounting type must be Surface Mount
Package must be compatible with TO-236-3, SC-59, or SOT-23-3 footprints
Moisture sensitivity level must be acceptable for the application environment

The 2SC4061KT146N from Rohm Semiconductor meets these substitution criteria. This device maintains the same 300 V breakdown voltage rating, exceeds the collector current requirement at 100 mA, maintains the 200 mW power rating, and is housed in an identical Surface Mount SOT-23-3 package. The substitute part is classified as Active product status, ensuring continued availability and supply chain support.

Engineering Selection Recommendations

The 2SC4061KT146N is a direct substitute for the obsolete 2SC58630QL based on the following factors:

Product Status: The 2SC4061KT146N is classified as Active product status, ensuring long-term availability and supply chain continuity. The original 2SC58630QL is obsolete, making the substitute necessary for ongoing production requirements.

Compliance & Certifications: The 2SC4061KT146N is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both devices carry ECCN EAR99 classification and share identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited).

Electrical Performance: The substitute device provides equal or superior electrical characteristics. The 300 V breakdown voltage rating is maintained, collector current capacity is increased from 70 mA to 100 mA, and transition frequency is improved from 80 MHz to 100 MHz. These enhancements provide design margin without introducing incompatibility.

Mechanical Compatibility: Both devices utilize identical Surface Mount packaging in the TO-236-3/SC-59/SOT-23-3 form factor, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 2SC4061KT146N directly replace the 2SC58630QL without circuit modifications?

A: Yes. Both devices share identical voltage ratings (300 V), power dissipation (200 mW), operating temperature range (150°C), and Surface Mount SOT-23-3 package specifications. The substitute provides equal or superior electrical performance across all critical parameters.

Q: What are the key differences between these two transistors?

A: The 2SC4061KT146N provides higher maximum collector current (100 mA versus 70 mA), improved transition frequency (100 MHz versus 80 MHz), and lower collector cutoff current (500 nA versus 1 µA). The substitute exhibits slightly higher saturation voltage (2V versus 1.2V at specified conditions). These differences represent performance enhancements suitable for direct substitution.

Q: Is the 2SC4061KT146N available in the same package as the original part?

A: Yes. Both devices are housed in the TO-236-3/SC-59/SOT-23-3 Surface Mount package. PCB footprints are identical, and no layout changes are required for substitution.

Q: What is the product status difference between these parts?

A: The 2SC58630QL is classified as Obsolete, indicating discontinued production and limited availability. The 2SC4061KT146N is classified as Active, ensuring continued manufacturing and supply chain support for future production runs.

Q: Are there any compliance or regulatory differences?

A: Both devices carry identical ECCN EAR99 classification and MSL 1 (Unlimited) ratings. The 2SC4061KT146N additionally provides RoHS3 Compliance and REACH Unaffected status, meeting current environmental regulations.

Q: What packaging options are available for the substitute part?

A: The 2SC4061KT146N is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both manual assembly and automated production environments.
