Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SB1184-P-TP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Transistor Type: PNP
• Collector Current (Max): 3 A
• Collector-Emitter Breakdown Voltage (Max): 50 V
• Power Dissipation (Max): 1 W
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63

Allowable Variation Parameters:

• Frequency - Transition: Equal to or greater than 70 MHz
• DC Current Gain (hFE): Equal to or greater than specified minimum
• Vce Saturation: Equal to or lower than specified maximum
• Operating Temperature Range: Must encompass or exceed -55°C to 150°C

The 2SB1202T-TL-E meets all mandatory matching parameters and exceeds allowable variation thresholds, qualifying it as a direct substitute. The 2SB1202T-TL-E provides superior frequency response (150 MHz versus 70 MHz) and higher DC current gain (200 @ 100mA, 2V versus 82 @ 500mA, 3V), while maintaining identical voltage and current ratings within the same package footprint.

Engineering Selection Recommendations

2SB1184-P-TP (Primary Selection)

The 2SB1184-P-TP is recommended for new designs and applications requiring active product status with ongoing manufacturer support. This part is currently in production with 823 units in stock, ensuring supply continuity. The device carries REACH Unaffected status and EAR99 classification, meeting regulatory requirements for standard commercial applications.

2SB1202T-TL-E (Substitute Selection)

The 2SB1202T-TL-E qualifies as a direct electrical and mechanical substitute, meeting all mandatory parameter requirements. This onsemi device provides enhanced performance characteristics, including doubled transition frequency (150 MHz versus 70 MHz) and improved DC current gain. However, the 2SB1202T-TL-E carries Obsolete product status, indicating discontinued manufacturing. This part is suitable for replacement applications, legacy system maintenance, or inventory consolidation where supply availability is confirmed. The device is RoHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating and maintains REACH Unaffected and EAR99 compliance.

Compliance Considerations

Both parts maintain identical regulatory classifications (REACH Unaffected, EAR99) and identical HTSUS codes (8541.29.0075), supporting seamless substitution from a compliance perspective. The 2SB1202T-TL-E's RoHS3 compliance provides additional environmental certification beyond the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the 2SB1202T-TL-E directly replace the 2SB1184-P-TP in existing designs?

A: Yes. Both devices share identical electrical ratings (3 A collector current, 50 V breakdown voltage, 1 W power dissipation) and identical package footprints (TO-252-3, DPAK). The 2SB1202T-TL-E provides superior frequency response and current gain, making it functionally compatible for all applications within the specified parameter envelope.

Q: What is the primary difference between these two parts?

A: The 2SB1202T-TL-E operates at 150 MHz transition frequency compared to the 2SB1184-P-TP's 70 MHz, and exhibits higher DC current gain (200 versus 82 minimum). Both maintain identical maximum ratings for current, voltage, and power dissipation. The 2SB1184-P-TP is currently active in production, while the 2SB1202T-TL-E is obsolete.

Q: Are there package compatibility concerns?

A: No. Both parts use the TO-252-3 DPAK package with identical pinout and footprint (SC-63). Direct PCB substitution is supported without layout modifications.

Q: What does "Obsolete" product status mean for the 2SB1202T-TL-E?

A: Obsolete status indicates the manufacturer has discontinued production. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed. This part is suitable for replacement or maintenance applications where current stock is confirmed available.

Q: How do the saturation voltage specifications differ?

A: The 2SB1184-P-TP specifies 1 V saturation at 200 mA base current and 2 A collector current. The 2SB1202T-TL-E specifies 700 mV saturation at 100 mA base current and 2 A collector current. The lower saturation voltage of the 2SB1202T-TL-E indicates improved switching efficiency at the specified operating point.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts carry identical REACH Unaffected and EAR99 classifications. The 2SB1202T-TL-E additionally carries RoHS3 Compliance certification. Both maintain the same HTSUS code (8541.29.0075).

Q: What is the operating temperature difference?

A: The 2SB1184-P-TP specifies -55°C to 150°C operating range. The 2SB1202T-TL-E specification provided lists 150°C maximum only. For applications requiring the full -55°C to 150°C range, verification of the 2SB1202T-TL-E's minimum operating temperature is necessary through the manufacturer datasheet.
