Key Parameters

Substitute Part Grouping Explanation

Substitution of the BS08D-112 is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Breakover: 7 ~ 9V (exact match required)
• Current - Breakover: 200 µA (exact match required)
• Current - Hold (Ih) (Max): 1.5 mA (exact match required)
• Current - Peak Output: 1 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (TJ) (exact match required)
• Package / Case: TO-226-3 or TO-92-3 configuration (mechanical compatibility required)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (exact match required)

The BS08D-T112 meets all specified electrical and thermal parameters. The primary distinction is packaging format: the BS08D-112 is supplied in standard tube or reel format, while the BS08D-T112 is supplied in Cut Tape (CT) format with formed leads. Both devices share identical electrical characteristics and thermal operating ranges, making them functionally equivalent for circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The BS08D-T112 is the direct functional equivalent for the obsolete BS08D-112. Selection of the BS08D-T112 is supported by:

• Electrical Equivalence: All breakover voltage, breakover current, hold current, and peak output specifications are identical.
• Thermal Compatibility: Operating temperature range matches exactly (-55°C ~ 125°C TJ).
• Package Compatibility: Both devices use TO-92-3 Short Body configuration. The BS08D-T112 features formed leads in Cut Tape packaging, which is compatible with standard TO-92-3 footprints.
• Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications.
• Active Product Status: The BS08D-T112 is currently in active production, ensuring long-term availability and supply chain continuity.
• RoHS Compliance: The BS08D-T112 is ROHS3 compliant, meeting current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the BS08D-T112 be used as a direct replacement for the BS08D-112?

A: Yes. The BS08D-T112 is electrically and thermally identical to the BS08D-112. Both devices share the same breakover voltage (7–9V), breakover current (200 µA), hold current (1.5 mA maximum), and peak output current (1 A). Operating temperature ranges are identical (-55°C ~ 125°C TJ). The primary difference is packaging format: Cut Tape with formed leads versus standard tube/reel format.

Q: What is the difference between the BS08D-112 and BS08D-T112 packaging?

A: The BS08D-112 is supplied in standard tube or reel format. The BS08D-T112 is supplied in Cut Tape (CT) format with pre-formed leads. Both use the TO-92-3 Short Body package configuration. The formed leads on the BS08D-T112 are compatible with standard TO-92-3 PCB footprints and do not affect electrical performance.

Q: Why is the BS08D-112 listed as obsolete?

A: The BS08D-112 has been discontinued by the manufacturer. The BS08D-T112 remains in active production and serves as the current production equivalent.

Q: Are there any compliance differences between the two parts?

A: No. Both parts carry identical ECCN (EAR99) and HTSUS (8541.30.0080) classifications. The BS08D-T112 is additionally certified as ROHS3 compliant, meeting current environmental standards.

Q: Can the BS08D-T112 be used in applications requiring the exact same thermal performance?

A: Yes. Both devices operate across the identical temperature range of -55°C ~ 125°C (TJ) and share the same thermal characteristics. No thermal performance differences exist between the two parts.

Q: Is the BS08D-T112 suitable for high-volume production?

A: Yes. The BS08D-T112 is in active production with substantial inventory availability (18,942 pcs in stock). Cut Tape packaging is standard for automated assembly processes.
