Substitute Part Grouping Explanation

Substitution of the 2SC1008-Y-AP is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Transistor polarity: NPN
• Maximum collector current: 700 mA
• Collector-emitter breakdown voltage: 60 V
• Vce saturation characteristics: 400 mV @ 50 mA, 500 mA
• Collector cutoff current: 100 nA (ICBO)
• DC current gain (hFE): minimum 120 @ 50 mA, 2 V
• Maximum power dissipation: 800 mW

Mechanical Specifications:

• Mounting type: Through Hole
• Package designation: TO-92-3 (TO-226AA)

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

Substitute parts must match all electrical parameters and mechanical specifications without deviation. Frequency-transition specifications may vary within the active product range without affecting functional substitution in standard switching and amplification circuits.

Parameter Comparison

Engineering Selection Recommendations

The KSC1008YBU manufactured by Fairchild Semiconductor is a direct electrical and mechanical equivalent to the 2SC1008-Y-AP. All critical electrical parameters—collector current, breakdown voltage, saturation characteristics, cutoff current, and DC current gain—are identical. Both devices utilize the TO-92-3 (TO-226AA) Through Hole package, ensuring mechanical compatibility in existing circuit board layouts and assembly processes.

The primary advantage of the KSC1008YBU is its active product status. The 2SC1008-Y-AP is obsolete, making the KSC1008YBU the appropriate selection for new designs, repairs, and component replenishment. The KSC1008YBU exhibits a higher transition frequency of 50 MHz compared to the 2SC1008-Y-AP at 30 MHz; this enhancement does not compromise compatibility and provides improved performance margin in high-frequency applications.

Both devices comply with RoHS3 requirements. The KSC1008YBU is suitable for direct substitution in all applications where the 2SC1008-Y-AP was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the KSC1008YBU replace the 2SC1008-Y-AP in existing designs?

A: Yes. The KSC1008YBU is electrically and mechanically equivalent to the 2SC1008-Y-AP. All critical electrical parameters match exactly, and both devices use the TO-92-3 package. Direct substitution is supported without circuit modification.

Q: What is the significance of the higher transition frequency in the KSC1008YBU?

A: The KSC1008YBU operates at 50 MHz compared to the 2SC1008-Y-AP at 30 MHz. This higher frequency capability does not affect compatibility in standard switching and low-frequency amplification circuits. In applications requiring high-frequency performance, the KSC1008YBU provides additional operational margin.

Q: Are there any package compatibility concerns?

A: No. Both the 2SC1008-Y-AP and KSC1008YBU use the TO-92-3 (TO-226AA) Through Hole package with formed leads. Pin configuration and mechanical dimensions are identical, ensuring direct board-level compatibility.

Q: Why is the 2SC1008-Y-AP classified as obsolete?

A: The 2SC1008-Y-AP has been discontinued by its manufacturer, Micro Commercial Co. The KSC1008YBU from Fairchild Semiconductor remains in active production and is the recommended alternative for ongoing component sourcing.

Q: Are both devices RoHS3 compliant?

A: The 2SC1008-Y-AP is confirmed RoHS3 compliant. The KSC1008YBU is suitable for RoHS3 applications. Compliance documentation should be verified with the supplier for the specific production lot.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is determined by matching transistor type (NPN), maximum collector current (700 mA), collector-emitter breakdown voltage (60 V), saturation voltage characteristics (400 mV @ 50 mA, 500 mA), collector cutoff current (100 nA), DC current gain (120 minimum @ 50 mA, 2 V), and maximum power dissipation (800 mW). The KSC1008YBU meets all these criteria.
