Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SC5459(TOJS,Q,M) is determined by alignment of the following critical electrical and mechanical parameters:

• Transistor Type: NPN polarity must be maintained
• Voltage Rating: Collector-emitter breakdown voltage must meet or exceed 400 V
• Current Rating: Maximum collector current must support 3 A operation
• Power Dissipation: Maximum power rating must accommodate 2 W
• Saturation Characteristics: Vce saturation performance at specified bias conditions
• Current Gain: DC current gain (hFE) must meet minimum specifications
• Package Type: Through-hole mounting in TO-220 or equivalent form factor
• Compliance Status: RoHS compliance and regulatory certifications (ECCN, HTSUS)

The 2SC5354,TOJSQ(O) is identified as a substitute part manufactured by Toshiba Semiconductor and Storage. This part maintains NPN transistor topology and is classified as an active product with RoHS compliance certification.

Frequently Asked Questions (FAQ)

Q: Why is the 2SC5459(TOJS,Q,M) classified as obsolete?

A: The 2SC5459(TOJS,Q,M) is no longer in active production. The 2SC5354,TOJSQ(O) represents the current active equivalent from the same manufacturer.

Q: What are the critical parameters for substitution of NPN transistors in this voltage and current class?

A: Substitution requires matching or exceeding the collector-emitter breakdown voltage (400 V), maximum collector current (3 A), power dissipation (2 W), and saturation characteristics. The transistor type (NPN) and package form factor (through-hole TO-220) must remain consistent.

Q: Does the 2SC5354,TOJSQ(O) meet the same regulatory requirements as the 2SC5459(TOJS,Q,M)?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications. The 2SC5354,TOJSQ(O) carries RoHS compliance certification, which exceeds the regulatory status of the obsolete part.

Q: Are there package compatibility considerations between these parts?

A: The 2SC5459(TOJS,Q,M) uses a TO-220-3 through-hole package. Verification of the 2SC5354,TOJSQ(O) package configuration is required to confirm mechanical and thermal interface compatibility in the target application.

Q: What is the inventory status of these parts?

A: The 2SC5459(TOJS,Q,M) has 1050 pieces in stock as new original inventory. The 2SC5354,TOJSQ(O) has 746 pieces in stock as new original inventory.

Q: Can the 2SC5354,TOJSQ(O) be used in all applications where the 2SC5459(TOJS,Q,M) was specified?

A: Substitution is valid where the electrical parameters (voltage, current, power, and gain characteristics) of the 2SC5354,TOJSQ(O) meet or exceed the design requirements of the original application. Package and thermal interface compatibility must be confirmed for the specific mounting configuration.
