Engineering Selection Recommendations

The BC33716_J35Z is classified as obsolete. Both substitute parts—BC33716BU and BC33716TA—are manufactured by Fairchild Semiconductor and carry active product status, ensuring continued availability and supply chain reliability.

BC33716BU is supplied in bulk packaging and maintains all electrical and mechanical specifications identical to the original part. This option is suitable for production environments requiring high-volume component sourcing.

BC33716TA is supplied in standard packaging and maintains all electrical and mechanical specifications identical to the original part. This option is suitable for general component replacement and repair applications.

Both substitute parts are classified under ECCN EAR99 and HTSUS 8541.21.0075, matching the regulatory classification of the original component. Selection between BC33716BU and BC33716TA depends on packaging requirements and supply chain logistics rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can BC33716BU and BC33716TA be used interchangeably with BC33716_J35Z?

A: Yes. Both substitute parts maintain identical electrical parameters (800 mA maximum collector current, 45 V breakdown voltage, 625 mW power dissipation, 100 MHz transition frequency, and 100 minimum DC current gain) and identical mechanical specifications (TO-92-3 through-hole package). Direct substitution is supported without circuit modification.

Q: What is the difference between BC33716BU and BC33716TA?

A: The primary difference is packaging format. BC33716BU is supplied in bulk packaging, while BC33716TA is supplied in standard packaging. Electrical and mechanical specifications are identical. Selection depends on procurement and inventory management requirements.

Q: Why is the BC33716_J35Z listed as obsolete?

A: The BC33716_J35Z is no longer manufactured by onsemi. However, equivalent parts from active product lines are available from Fairchild Semiconductor, ensuring continued access to functionally identical components.

Q: Are there any compliance or regulatory differences between the original and substitute parts?

A: No. All parts share identical ECCN (EAR99) and HTSUS (8541.21.0075) classifications, ensuring equivalent regulatory treatment in export and import applications.

Q: What parameters must remain identical for a part to be considered a direct substitute?

A: Direct substitution requires matching transistor type (NPN), maximum collector current (800 mA), collector-emitter breakdown voltage (45 V), maximum power dissipation (625 mW), DC current gain (100 minimum @ 100 mA, 1 V), transition frequency (100 MHz), saturation voltage (700 mV @ 50 mA, 500 mA), collector cutoff current (100 nA maximum), operating temperature (150°C), and package configuration (TO-92-3 through-hole).

Q: Can these parts be used in new designs?

A: Yes. Both BC33716BU and BC33716TA carry active product status and are suitable for new design implementations. The BC33716_J35Z, being obsolete, is not recommended for new designs; however, the active substitutes provide equivalent functionality.
