Key Parameters

Substitute Part Grouping Explanation

Substitution of the TIS93 is determined by electrical and mechanical parameter alignment within the PNP BJT category. The critical parameters governing substitution are:

• Transistor Type: PNP configuration
• Maximum Collector Current (Ic): 800 mA minimum requirement
• Collector-Emitter Breakdown Voltage (VCEO): 40 V minimum rating
• Maximum Power Dissipation: 625 mW minimum capability
• Operating Temperature Range: −55°C to 150°C coverage
• Package Type: TO-92-3 through-hole form factor
• DC Current Gain (hFE): Minimum 100 at specified operating point

The PN2907BU manufactured by Fairchild Semiconductor satisfies all electrical and mechanical requirements for direct substitution. Both devices share identical maximum ratings for collector current, breakdown voltage, and power dissipation, operate across the same temperature range, and employ the same through-hole TO-92-3 package configuration.

Parameter Comparison

Engineering Selection Recommendations

The PN2907BU is a direct electrical and mechanical equivalent to the TIS93. Both devices are classified under the same ECCN (EAR99) and HTSUS (8541.21.0095) codes, confirming regulatory alignment.

The primary distinction between the two parts is product status: the TIS93 is obsolete, while the PN2907BU is active. For applications currently using the TIS93, transition to the PN2907BU ensures continued component availability and supply chain stability. The PN2907BU maintains identical electrical performance specifications and physical form factor, enabling direct board-level substitution without circuit redesign.

Both devices carry Moisture Sensitivity Level (MSL) 1 classification, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can the PN2907BU replace the TIS93 in existing circuit designs?

A: Yes. The PN2907BU meets or exceeds all electrical and mechanical specifications of the TIS93. Both devices are PNP BJTs with 800 mA maximum collector current, 40 V breakdown voltage, 625 mW power rating, and TO-92-3 through-hole packaging. Direct substitution is supported without circuit modification.

Q: Are there differences in saturation voltage between these parts?

A: The devices exhibit different saturation voltage characteristics at specified test conditions. The TIS93 specifies 250 mV maximum at 5 mA base current and 50 mA collector current. The PN2907BU specifies 1.6 V maximum at 50 mA base current and 500 mA collector current. Circuit designs must account for these differences if saturation voltage is a critical parameter.

Q: Do both parts use the same package footprint?

A: Yes. Both the TIS93 and PN2907BU employ the TO-92-3 (TO-226AA) through-hole package. Pin configuration and physical dimensions are identical, permitting direct board-level replacement.

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

A: The TIS93 specifies 100 nA maximum collector cutoff current (ICBO), while the PN2907BU specifies 20 nA maximum. The PN2907BU exhibits lower leakage current, which may provide improved performance in low-power or high-impedance applications.

Q: Are there supply chain advantages to using the PN2907BU?

A: Yes. The PN2907BU is classified as active product status with significantly higher inventory availability (22,103 pieces in stock versus 1,120 pieces for the TIS93). The PN2907BU ensures reliable long-term component sourcing.

Q: Do both parts comply with the same regulatory standards?

A: Yes. Both the TIS93 and PN2907BU carry identical ECCN (EAR99) and HTSUS (8541.21.0095) classifications, confirming equivalent regulatory compliance and export control status.
