2SB1184-R-TP Equivalent & Substitute Parts

Part Overview

The 2SB1184-R-TP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, designed for general-purpose switching and amplification applications. This surface mount device operates at 50V collector-emitter breakdown voltage with a maximum collector current of 3A and 1W power dissipation capability. The part is currently in active product status with 756 units available in inventory.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements allow for alternative components with compatible electrical and mechanical specifications. The 2SB1202T-TL-E represents an available alternative that maintains critical electrical parameters while offering enhanced frequency performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2SB1184-R-TP is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 3 A
• Voltage - Collector Emitter Breakdown (Max): 50 V
• Power - Max: 1 W
• Operating Temperature (TJ): 150°C
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The 2SB1202T-TL-E meets all mandatory matching parameters and qualifies as a direct electrical and mechanical substitute. Secondary parameters such as DC Current Gain (hFE), Vce Saturation, and Frequency - Transition may vary within acceptable ranges for the application without affecting substitution validity.

Engineering Selection Recommendations

2SB1184-R-TP (Primary Selection)

The 2SB1184-R-TP is the recommended primary component for new designs and applications. This part maintains active product status with established supply availability (756 units in stock). Full ROHS3 compliance and REACH unaffected status confirm regulatory alignment for current manufacturing standards.

2SB1202T-TL-E (Substitute Selection)

The 2SB1202T-TL-E qualifies as a direct substitute when the primary part is unavailable or when design requirements permit component substitution. This part satisfies all mandatory electrical and mechanical parameters. However, the obsolete product status indicates this component is no longer in active production. The higher inventory level (13,201 units) may provide short-term availability, but long-term sourcing should not rely on this part.

Both parts carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1) and operate within the same thermal envelope (150°C TJ). The physical package compatibility (TO-252-3, DPAK) ensures direct PCB layout interchangeability without redesign.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical maximum ratings for collector current (3A), collector-emitter breakdown voltage (50V), power dissipation (1W), and operating temperature (150°C). The physical package (TO-252-3, DPAK) is identical, enabling direct PCB substitution without layout modification.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer (Micro Commercial Co versus onsemi), product status (Active versus Obsolete), and secondary electrical characteristics. The 2SB1202T-TL-E exhibits higher DC current gain (200 versus 82 at different test conditions), lower Vce saturation (700mV versus 1V), and higher transition frequency (150MHz versus 70MHz). These differences do not affect substitution validity for applications within the specified maximum ratings.

Q: Are the packages physically identical?

A: Yes. Both parts use the TO-252-3 DPAK package with 2 leads plus tab (SC-63). Pin configuration and PCB footprint are identical, allowing direct component substitution without board redesign.

Q: What is the significance of the obsolete status for the 2SB1202T-TL-E?

A: Obsolete status indicates the manufacturer has discontinued active production. While current inventory exists (13,201 units), future availability cannot be guaranteed. This part should be used only when the primary part is unavailable and only for applications where long-term supply is not critical.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the 2SB1184-R-TP and 2SB1202T-TL-E are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.

Q: What packaging formats are available for these parts?

A: The 2SB1184-R-TP is supplied in Tape & Reel (TR) format. The 2SB1202T-TL-E is supplied in Cut Tape (CT) and Digi-Reel® format. Both formats are suitable for automated assembly processes, though reel specifications may differ.
