BSP60,115 Equivalent & Substitute Parts

Part Overview

The BSP60,115 is a PNP Darlington bipolar junction transistor manufactured by Nexperia USA Inc., designed for surface mount applications in the SOT-223 package. This component operates at a maximum collector current of 1 A with a collector-emitter breakdown voltage of 45 V, making it suitable for low-to-medium power switching and amplification circuits. The device is actively produced and maintains full automotive qualification under AEC-Q101 standards with ROHS3 compliance.

Substitute parts become necessary when the primary component reaches end-of-life status, experiences supply constraints, or when design flexibility requires alternative sourcing from qualified manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the BSP60,115 with the BSP60H6327XTSA1 is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Transistor topology: Both are PNP Darlington configurations
• Maximum collector current: 1 A (identical)
• Collector-emitter breakdown voltage: 45 V (identical)
• DC current gain minimum: 2000 @ 500mA, 10V (identical)
• Transition frequency: 200 MHz (identical)
• Maximum operating temperature: 150°C (identical)
• Mounting technology: Surface Mount (identical)
• Physical package: TO-261-4, TO-261AA (identical)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected (identical)
• Moisture sensitivity: MSL 1 (Unlimited) (identical)

Variant Parameters:

• Power dissipation: BSP60,115 rated at 1.25 W; BSP60H6327XTSA1 rated at 1.5 W (substitute exceeds specification)
• Vce saturation: BSP60,115 at 1.3V @ 500µA, 500mA; BSP60H6327XTSA1 at 1.8V @ 1mA, 1A (within acceptable operating range)
• Collector cutoff current: BSP60,115 at 50nA; BSP60H6327XTSA1 at 10µA (substitute exhibits higher leakage)

The BSP60H6327XTSA1 maintains functional equivalence for applications requiring the specified electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (BSP60,115): The BSP60,115 maintains Active product status with continuous manufacturing availability. This component is the preferred selection for new designs and ongoing production where supply is not constrained. Full automotive qualification under AEC-Q101 and ROHS3 compliance ensure suitability for regulated applications.

Substitute Component (BSP60H6327XTSA1): The BSP60H6327XTSA1 carries Last Time Buy status, indicating discontinued production with limited remaining inventory. This component is suitable for replacement in existing designs or as a secondary source when primary component availability is exhausted. The substitute maintains identical electrical performance specifications for the core switching and amplification functions, with enhanced power dissipation capability (1.5 W versus 1.25 W) and equivalent regulatory compliance.

Both components share identical package geometry (TO-261-4, TO-261AA), mechanical mounting requirements, and thermal operating limits, enabling direct substitution at the board assembly level without design modification.

Frequently Asked Questions (FAQ)

Q: Can the BSP60H6327XTSA1 be used as a direct replacement for the BSP60,115 in existing designs?

A: Yes. Both components share identical collector current (1 A), collector-emitter breakdown voltage (45 V), DC current gain (2000 @ 500mA, 10V), transition frequency (200 MHz), and physical package dimensions (TO-261-4, TO-261AA). The substitute operates within the same thermal envelope (150°C maximum junction temperature) and maintains equivalent regulatory compliance (ROHS3, REACH Unaffected).

Q: What are the differences in saturation voltage between these parts?

A: The BSP60,115 exhibits 1.3 V saturation voltage at 500µA base current and 500 mA collector current. The BSP60H6327XTSA1 exhibits 1.8 V saturation voltage at 1 mA base current and 1 A collector current. These measurements are taken at different bias points; both values remain within acceptable operating ranges for typical switching applications.

Q: Why does the BSP60H6327XTSA1 show higher collector cutoff current?

A: The BSP60,115 specifies 50 nA maximum cutoff current, while the BSP60H6327XTSA1 specifies 10 µA. This difference reflects manufacturing process variations between Nexperia and Infineon. For applications requiring minimal leakage current, the BSP60,115 provides superior performance; however, the BSP60H6327XTSA1 remains suitable for standard switching applications where this leakage level does not impact circuit function.

Q: Are there any packaging differences between these components?

A: Both components use the SOT-223 surface mount package with TO-261-4 and TO-261AA case designations. The supplier device package designation differs (SOT-223 versus PG-SOT223-4), but the physical footprint, lead spacing, and mounting requirements are identical. No PCB layout modifications are required for substitution.

Q: What is the significance of the Last Time Buy status for the BSP60H6327XTSA1?

A: Last Time Buy status indicates that Infineon has discontinued production of this component. Existing inventory remains available for purchase, but no new manufacturing runs are planned. For long-term production requirements, the Active-status BSP60,115 from Nexperia is the recommended primary source. The BSP60H6327XTSA1 is suitable for short-term replacement needs or as a secondary source when primary component allocation is insufficient.

Q: Do both components meet automotive qualification requirements?

A: The BSP60,115 carries explicit AEC-Q101 automotive qualification. The BSP60H6327XTSA1 specification does not list AEC-Q101 qualification in the provided data. For applications requiring automotive-grade components, the BSP60,115 is the specified choice. The BSP60H6327XTSA1 may be used in non-automotive applications or where customer-specific qualification has been established.
