Engineering Selection Recommendations

Primary Recommendation: BSP171PH6327XTSA1

The BSP171PH6327XTSA1 (Infineon Technologies) is the direct parametric equivalent to the obsolete BSP171PL6327HTSA1. This part maintains identical electrical specifications across all critical parameters: 60V Vdss, 1.9A continuous drain current, 300mOhm Rds On, and 20nC gate charge. The BSP171PH6327XTSA1 carries Active product status and ROHS3 compliance, with significantly higher inventory availability (20,486 units). The packaging designation differs slightly (PG-SOT223-4 versus PG-SOT223-4-21), but both conform to TO-261-4 and TO-261AA case standards, ensuring mechanical and electrical compatibility. This substitution requires no circuit redesign.

Secondary Recommendations:

NDT2955 (onsemi) provides enhanced current capability (2.5A versus 1.9A) and increased power dissipation rating (3W versus 1.8W) while maintaining 60V Vdss and 300mOhm Rds On specifications. This part is suitable for applications requiring higher current margins or thermal headroom. Product status is Active with ROHS3 compliance and high inventory (41,100 units).

PJW3P06A-AU_R2_000A1 (Panjit International Inc.) offers superior performance characteristics: 3A continuous drain current, 170mOhm Rds On, and 3.1W power dissipation. This part includes AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. Product status is Active with ROHS3 compliance. Gate charge is reduced to 8.3nC, improving switching speed performance.

DMP6250SE-13 (Diodes Incorporated) provides 2.1A continuous drain current with 250mOhm Rds On and enhanced power dissipation (14W at Tc). This part offers improved thermal performance and is suitable for applications with elevated ambient temperatures. Product status is Active with ROHS3 compliance.

ZXMP6A13GTA (Diodes Incorporated) is suitable only for applications where the 1.7A continuous drain current specification is acceptable. This part features the lowest gate charge (5.9nC) and input capacitance (219pF), optimizing switching performance in high-frequency applications. Product status is Active with ROHS3 compliance.

All substitute parts maintain the mandatory operating temperature range (-55°C to 150°C), MSL rating (1 - Unlimited), and surface mount configuration. Selection should be based on specific application current requirements, thermal constraints, and switching frequency demands.

Frequently Asked Questions (FAQ)

Q1: Can BSP171PH6327XTSA1 be used as a direct replacement for BSP171PL6327HTSA1?

A: Yes. The BSP171PH6327XTSA1 is a direct parametric equivalent with identical electrical specifications. Both parts feature 60V Vdss, 1.9A continuous drain current, 300mOhm Rds On, and 20nC gate charge. The packaging designation differs slightly (PG-SOT223-4 versus PG-SOT223-4-21), but both conform to TO-261-4 and TO-261AA case standards. No circuit modifications are required.

Q2: What is the difference between SOT-223-3 and SOT-223-4 packages?

A: SOT-223-3 contains three leads (Gate, Drain, Source), while SOT-223-4 contains four leads with an additional Drain connection for improved thermal performance. Both packages conform to TO-261-4 and TO-261AA case standards and are mechanically compatible with the original BSP171PL6327HTSA1 footprint. Verify PCB layout compatibility before substitution.

Q3: Which substitute part should I select if my application requires higher current capability?

A: NDT2955 (2.5A), PJW3P06A-AU_R2_000A1 (3.0A), or DMP6250SE-13 (2.1A) provide increased current ratings. Selection depends on specific current requirements and thermal constraints. PJW3P06A-AU_R2_000A1 offers the highest current rating (3.0A) with automotive qualification (AEC-Q101).

Q4: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts listed (BSP171PH6327XTSA1, DMP6250SE-13, NDT2955, PJW3P06A-AU_R2_000A1, ZXMP6A13GTA) carry ROHS3 compliance certification. The original BSP171PL6327HTSA1 (Obsolete) does not specify RoHS status.

Q5: Can ZXMP6A13GTA be used in applications requiring 1.9A continuous drain current?

A: No. ZXMP6A13GTA is rated for 1.7A continuous drain current at 25°C, which is below the 1.9A requirement of the original part. This substitution is suitable only for applications with maximum current requirements of 1.7A or less.

Q6: What is the significance of gate charge (Qg) differences among substitute parts?

A: Gate charge affects switching speed and driver power requirements. Lower gate charge (5.9nC for ZXMP6A13GTA, 8.3nC for PJW3P06A-AU_R2_000A1) enables faster switching and reduced driver power dissipation. Higher gate charge (20nC for BSP171PH6327XTSA1) requires more driver current but may provide improved noise immunity. Selection depends on switching frequency and driver capabilities.

Q7: Which substitute part is recommended for automotive applications?

A: PJW3P06A-AU_R2_000A1 carries AEC-Q101 automotive qualification and is specifically designed for automotive-grade applications. This part provides 3.0A continuous drain current, 170mOhm Rds On, and 3.1W power dissipation with Active product status and ROHS3 compliance.

Q8: What is the impact of Rds On variation among substitute parts?

A: Rds On (on-resistance) directly affects power dissipation and heat generation. Lower Rds On values (170mOhm for PJW3P06A-AU_R2_000A1, 250mOhm for DMP6250SE-13) reduce power loss and thermal stress. Higher Rds On values (390mOhm for ZXMP6A13GTA) increase power dissipation. Selection should account for application current levels and thermal design constraints.

Q9: Are all substitute parts available in the same packaging format?

A: All substitute parts are surface mount devices in SOT-223 variants (SOT-223-3 or SOT-223-4), which conform to TO-261-4 and TO-261AA case standards. Mechanical compatibility is maintained across all substitutes. Verify specific lead configuration (3-lead versus 4-lead) against PCB layout requirements.

Q10: What inventory status should be considered when selecting a substitute part?

A: BSP171PH6327XTSA1 offers the highest inventory availability (20,486 units), followed by NDT2955 (41,100 units) and DMP6250SE-13 (23,500 units). All listed substitutes maintain active production status with adequate supply. Inventory levels should be verified with suppliers for long-term production requirements.
