BCP52TA Equivalent & Substitute Parts
Part Overview
The BCP52TA is a PNP bipolar junction transistor manufactured by Diodes Incorporated, rated for 60 V collector-emitter breakdown voltage and 1 A maximum collector current. The device is housed in a SOT-223-3 surface mount package and operates across a temperature range of -65°C to 150°C. With an active product status and 28,200 units in stock, the BCP52TA serves as a standard switching and amplification component in low-power applications.
Equivalent and substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design requirements necessitate alternative electrical or mechanical characteristics. The substitute parts listed maintain functional compatibility through matching or exceeding the core electrical parameters while accommodating different packaging formats and manufacturer specifications.

Substitute Part Grouping Explanation
Substitute parts for the BCP52TA are classified into two primary categories based on electrical and mechanical compatibility:
Direct Electrical Equivalents maintain the core specifications of 60 V collector-emitter breakdown voltage and 1 A maximum collector current. These parts satisfy applications where the BCP52TA specifications are mandatory. Substitution within this group is determined by matching or exceeding the following parameters: maximum collector current, collector-emitter breakdown voltage, maximum power dissipation, and saturation voltage characteristics.
Functional Alternatives provide equivalent or superior performance in specific parameters while maintaining the 60 V / 1 A rating envelope. These parts may differ in transition frequency, DC current gain, or power rating but remain suitable for circuits designed around the BCP52TA electrical envelope.
Lower Voltage Alternatives operate at reduced collector-emitter breakdown voltage (45 V) and are applicable only in circuits where the lower voltage rating is acceptable. These parts are not interchangeable in applications requiring the full 60 V rating.
Higher Current Alternatives exceed the 1 A collector current specification and are suitable for applications requiring increased current handling capacity while maintaining the 60 V voltage rating.
The following key parameters determine substitution eligibility:
- Transistor type (PNP)
- Collector-emitter breakdown voltage (minimum 60 V for direct equivalents)
- Maximum collector current (minimum 1 A for direct equivalents)
- Maximum power dissipation (minimum 2 W for direct equivalents)
- Surface mount package compatibility (SOT-223 family)
- RoHS3 compliance and MSL rating

Engineering Selection Recommendations
Direct Electrical Equivalents (Recommended for Pin-Compatible Replacement)
FZT591TA (Diodes Incorporated) provides direct electrical equivalence with identical 60 V / 1 A ratings and 2 W power dissipation. The FZT591TA exhibits superior transition frequency (150 MHz versus 125 MHz) and higher DC current gain (100 versus 40), making it suitable for high-speed switching applications. Available in Cut Tape packaging with 25,094 units in stock. Both parts maintain ROHS3 compliance and MSL 1 rating.
BCP5216H6327XTSA1 (Infineon Technologies) matches the BCP52TA electrical specifications exactly, including 125 MHz transition frequency and 2 W power rating. This part carries a Last Time Buy status with limited inventory (1,068 units), indicating reduced long-term availability. Selection of this part is appropriate only when existing design validation specifically requires Infineon qualification or when supply of primary alternatives is constrained.
Nexperia Automotive-Grade Alternatives

Lower Voltage Alternative (Conditional Use)
BCP51,115 and BCP51-10,135 (Nexperia USA Inc.) operate at 45 V collector-emitter breakdown voltage with 1 A maximum current. These parts are suitable only in applications where the reduced voltage rating is acceptable. Both carry AEC-Q100 automotive qualification. Selection is appropriate for cost optimization in circuits not requiring the full 60 V rating.
Higher Current Alternative (Upgrade Path)
NSS60600MZ4T1G and NSS60600MZ4T3G (onsemi) provide 6 A maximum collector current at 60 V breakdown voltage. These parts are suitable for applications requiring increased current handling while maintaining the 60 V voltage rating. The 800 mW power rating is lower than the BCP52TA, requiring thermal analysis for high-power applications. Available in Cut Tape & Digi-Reel® (25,200 units) and Tape & Reel (2,400 units) respectively.
Legacy Alternative (Not Recommended for New Designs)
BSP31,115 (NXP USA Inc.) provides 60 V / 1 A operation with 1.3 W power rating and 100 MHz transition frequency. Available in Bulk packaging with 4,933 units in stock. This part is suitable for applications where existing design validation exists but is not recommended for new designs due to lower transition frequency compared to alternatives.
Frequently Asked Questions (FAQ)
Q: Can FZT591TA directly replace BCP52TA in existing designs?
A: FZT591TA is electrically equivalent to BCP52TA with matching 60 V / 1 A ratings and 2 W power dissipation. The primary difference is packaging format (Cut Tape versus Tape & Reel) and superior transition frequency (150 MHz versus 125 MHz). Direct replacement is possible in applications where the Cut Tape packaging is acceptable for assembly processes. Both parts maintain identical RoHS3 compliance and MSL 1 rating.
Q: What is the difference between BCP52,135 and BCP52TA?
A: BCP52,135 is manufactured by Nexperia USA Inc. and carries AEC-Q100 automotive qualification, whereas BCP52TA is manufactured by Diodes Incorporated without automotive grading. Both maintain 60 V / 1 A electrical specifications. BCP52,135 features 145 MHz transition frequency (versus 125 MHz) and reduced power rating (1 W versus 2 W). Selection of BCP52,135 is appropriate for automotive applications or when Nexperia supply chain is preferred.
Q: Are the Nexperia BCP51 series parts compatible with BCP52TA?
A: BCP51 series parts operate at 45 V collector-emitter breakdown voltage, which is lower than the BCP52TA 60 V rating. These parts are not direct replacements and are suitable only in applications where the reduced voltage rating does not compromise circuit performance. Both BCP51,115 and BCP51-10,135 carry AEC-Q100 automotive qualification.
Q: When should NSS60600MZ4T1G or NSS60600MZ4T3G be selected?
A: The NSS60600 series provides 6 A maximum collector current at 60 V breakdown voltage, making these parts suitable for applications requiring higher current handling than the 1 A BCP52TA rating. These parts are not direct replacements due to different current ratings and lower power dissipation (800 mW). Selection is appropriate when circuit design requires increased current capacity while maintaining 60 V voltage rating.
Q: What is the significance of the Last Time Buy status for BCP5216H6327XTSA1?
A: Last Time Buy status indicates that the manufacturer (Infineon Technologies) has announced end-of-life for this part. Existing inventory (1,068 units) represents the final available stock. This part should be selected only when existing design validation specifically requires Infineon qualification or when alternative sources are unavailable. For new designs, FZT591TA or Nexperia alternatives are recommended.
Q: Are all substitute parts RoHS3 compliant?
A: All listed substitute parts maintain ROHS3 compliance. The BCP52TA, FZT591TA, BCP5216H6327XTSA1, Nexperia BCP51/BCP52 series, and NSS60600 series all carry ROHS3 Compliant status. BSP31,115 compliance status is not specified in the provided data.
Q: What packaging formats are available for BCP52TA equivalents?
A: Substitute parts are available in multiple packaging formats: Tape & Reel (TR), Cut Tape (CT), Cut Tape & Digi-Reel®, and Bulk. The original BCP52TA is supplied in Tape & Reel format. Selection of packaging format depends on assembly process requirements and volume specifications. Nexperia parts offer the widest range of packaging options.
Q: Can BSP31,115 be used as a direct replacement for BCP52TA?
A: BSP31,115 provides 60 V / 1 A operation with 1.3 W power rating, making it electrically compatible with BCP52TA. However, the 100 MHz transition frequency is lower than BCP52TA (125 MHz), which may impact performance in high-speed switching applications. This part is suitable for applications where lower transition frequency is acceptable and existing design validation exists.
