Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSC5367FTU is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Voltage - Collector Emitter Breakdown rating must be 800 V or greater
• Current - Collector (Ic) maximum rating must meet or exceed 3 A
• DC Current Gain (hFE) minimum must be 12 or greater at specified operating conditions
• Operating temperature range must support 150°C junction temperature

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Package must be TO-220-3 or equivalent footprint

The BUL216 manufactured by STMicroelectronics satisfies all substitution criteria. This device is classified as active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The BUL216 is the qualified substitute for the KSC5367FTU based on the following engineering factors:

Product Status: The BUL216 carries active product status, providing assured long-term availability and supply chain stability. The KSC5367FTU is obsolete, making substitution necessary for production continuity.

Electrical Performance: The BUL216 meets all minimum electrical requirements of the KSC5367FTU. The substitute device provides higher maximum collector current (4 A versus 3 A) and greater power dissipation capability (90 W versus 40 W), enabling operation within the original design envelope with additional performance margin.

Compliance & Certifications: Both devices carry identical REACH status (REACH Unaffected) and ECCN classification (EAR99). The BUL216 is RoHS3 compliant, meeting current regulatory requirements. Both devices have Moisture Sensitivity Level 1 (Unlimited).

Mechanical Compatibility: Both devices utilize identical TO-220-3 through-hole packaging, ensuring direct mechanical and thermal interface compatibility without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the BUL216 directly replace the KSC5367FTU without circuit modification?

A: The BUL216 is electrically and mechanically compatible with the KSC5367FTU. Both devices share identical voltage ratings (800 V), equivalent DC current gain specifications (12 minimum), and identical TO-220-3 packaging. The BUL216 provides higher current and power ratings, which do not require circuit modification for applications designed for the KSC5367FTU.

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

A: The primary differences are product status and performance headroom. The KSC5367FTU is obsolete; the BUL216 is active. The BUL216 provides higher maximum collector current (4 A versus 3 A) and power dissipation (90 W versus 40 W). The BUL216 exhibits higher collector cutoff current (250 µA versus 20 µA) and different saturation voltage characteristics at higher current levels.

Q: Are there any thermal management considerations when substituting?

A: Both devices operate at identical maximum junction temperatures (150°C) and use the same TO-220-3 package. Thermal management requirements remain unchanged. The BUL216's higher power rating provides additional thermal margin for the same application.

Q: What is the impact of different Vce saturation specifications?

A: The BUL216 exhibits 3V saturation voltage at 660mA/2A compared to the KSC5367FTU's 2.5V at 200mA/1A. These measurements occur at different operating points. For applications operating within the original KSC5367FTU design parameters, saturation voltage differences do not affect circuit functionality.

Q: Is the BUL216 available in the same packaging format?

A: Yes. Both devices use TO-220-3 through-hole packaging. The BUL216 is supplied in tube packaging, while the KSC5367FTU was supplied in full pack format. This difference affects only handling and storage; the component footprint and thermal interface remain identical.

Q: What compliance certifications apply to the BUL216?

A: The BUL216 is RoHS3 compliant and carries REACH Unaffected status. Both devices share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications. Moisture Sensitivity Level is 1 (Unlimited) for both devices.
