Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD667-C-AP is determined by electrical and mechanical parameter alignment within the NPN bipolar transistor category. The primary substitution criteria are:

Electrical Parameters:

• Collector-emitter breakdown voltage: 80 V (exact match required)
• Maximum collector current: 1 A (exact match required)
• Transistor polarity: NPN (exact match required)
• Operating temperature range: -55°C to 150°C (exact match required)
• DC current gain minimum: 100 @ specified conditions (minimum threshold)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package classification: TO-92-3 form factor (exact match required)

The BC63916-D74Z manufactured by onsemi satisfies all substitution criteria. This part maintains identical voltage and current ratings, operates across the same temperature range, and utilizes the same through-hole TO-92-3 package configuration. Both devices are RoHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the BC63916-D74Z directly replace the 2SD667-C-AP in existing circuits?

A: Yes. Both devices share identical voltage ratings (80 V), current ratings (1 A), operating temperature range (-55°C to 150°C), and TO-92-3 package configuration. Direct pin-for-pin substitution is supported without circuit modification.

Q: What is the significance of the lower saturation voltage in the BC63916-D74Z?

A: The BC63916-D74Z exhibits 500 mV saturation voltage compared to 1 V in the 2SD667-C-AP. This represents improved switching efficiency and reduced power dissipation during saturation conditions, beneficial for switching applications.

Q: Why does the 2SD667-C-AP have higher transition frequency than the BC63916-D74Z?

A: The 2SD667-C-AP specifies 140 MHz transition frequency versus 100 MHz for the BC63916-D74Z. For applications operating below 100 MHz, the BC63916-D74Z is fully compatible. Applications requiring operation above 100 MHz should evaluate frequency-dependent performance requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2SD667-C-AP and BC63916-D74Z are RoHS3 compliant, meeting environmental and regulatory standards for electronic component manufacturing and deployment.

Q: What is the difference in collector cutoff current between these parts?

A: The BC63916-D74Z specifies 100 nA maximum collector cutoff current (ICBO) compared to 10 µA for the 2SD667-C-AP. Lower cutoff current in the BC63916-D74Z indicates reduced leakage current, which may improve circuit performance in low-power or high-impedance applications.

Q: Is the BC63916-D74Z available in the same packaging format?

A: Yes. Both devices utilize the TO-92-3 through-hole package with formed leads, ensuring identical mechanical compatibility and circuit board mounting procedures.

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

A: The 2SD667-C-AP is classified as obsolete with limited inventory availability. The BC63916-D74Z maintains active production status with substantial current inventory (8253 units), ensuring reliable long-term supply for production and design requirements.
