Engineering Selection Recommendations

BSP170PH6327XTSA1 (Infineon Technologies)

This part is a parametric equivalent to the BSP170PL6327HTSA1, sharing identical electrical specifications while maintaining Active product status. The BSP170PH6327XTSA1 is supplied in Cut Tape (CT) and Digi-Reel® packaging with significantly higher inventory availability (16,978 pcs). Both parts are ROHS3 Compliant and carry identical REACH and ECCN classifications. This substitute is recommended as the primary replacement for obsolete stock management and new design implementations.

DMP6250SE-13 (Diodes Incorporated)

This part provides enhanced current capability (2.1A vs. 1.9A) and improved on-resistance characteristics (250mOhm @ 1A, 10V). The DMP6250SE-13 offers superior thermal performance with 14W power dissipation at Tc and lower gate charge (9.7 nC). Packaging is SOT-223-3 (three-pin configuration vs. four-pin). This substitute is suitable for applications where increased current margin and thermal headroom are beneficial. Inventory availability is high (23,500 pcs). ROHS3 Compliant.

NDT2955 (onsemi)

This part delivers the highest current rating (2.5A) and power dissipation capability (3W Ta) among all substitutes. The NDT2955 maintains 300mOhm on-resistance at rated conditions and is packaged in SOT-223-4 (four-pin, matching the original package pin count). This substitute is recommended for applications requiring maximum current headroom and thermal margin. Inventory availability is excellent (41,100 pcs). ROHS3 Compliant.

ZXMP6A13GTA (Diodes Incorporated)

This part features the lowest gate charge (5.9 nC) and input capacitance (219 pF @ 30V), making it suitable for high-frequency switching applications. Current rating is 1.7A, slightly below the original specification. On-resistance is higher at 390mOhm @ 900mA, 10V. Packaging is SOT-223-3 (three-pin). This substitute is recommended for applications prioritizing switching speed and gate drive efficiency. Inventory availability is adequate (15,465 pcs). ROHS3 Compliant.

All substitute parts meet the mandatory electrical and mechanical compatibility criteria. Selection should be based on specific application requirements regarding current capacity, thermal dissipation, switching frequency, and package pin configuration.

Frequently Asked Questions (FAQ)

Q: Can BSP170PH6327XTSA1 be used as a direct drop-in replacement for BSP170PL6327HTSA1?

A: Yes. The BSP170PH6327XTSA1 is a parametric equivalent with identical electrical specifications (60V Vdss, 1.9A Id, 300mOhm Rds On, 14 nC Qg). Both parts use PG-SOT223-4 packaging with TO-261-4 and TO-261AA case compatibility. The primary difference is product status (Active vs. Obsolete) and packaging format (Digi-Reel vs. standard). No circuit modifications are required.

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

A: SOT-223-3 contains three pins (Gate, Drain, Source), while SOT-223-4 contains four pins (Gate, Drain, Source, and an additional Drain pin for improved thermal performance). Both are surface mount packages with TO-261-4 and TO-261AA case compatibility. Applications using the original four-pin configuration should verify that three-pin alternatives (DMP6250SE-13, ZXMP6A13GTA) do not require the fourth pin connection.

Q: Which substitute part should I select if my application requires maximum current capacity?

A: The NDT2955 provides the highest continuous drain current rating at 2.5A (vs. 1.9A original) and the highest power dissipation capability at 3W Ta. This part is recommended for applications where current margin and thermal headroom are critical design factors.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. All four substitute parts (BSP170PH6327XTSA1, DMP6250SE-13, NDT2955, ZXMP6A13GTA) are ROHS3 Compliant. The original BSP170PL6327HTSA1 does not specify RoHS status. All parts carry identical REACH Unaffected and EAR99 ECCN classifications.

Q: Which substitute part has the fastest switching characteristics?

A: The ZXMP6A13GTA exhibits the lowest gate charge (5.9 nC) and input capacitance (219 pF), resulting in faster switching transitions. This part is recommended for high-frequency switching applications where gate drive efficiency and switching speed are primary design considerations.

Q: Can I use DMP6250SE-13 in a circuit designed for the original BSP170PL6327HTSA1?

A: The DMP6250SE-13 is electrically compatible with identical Vdss (60V), Vgs (±20V), and operating temperature range (-55°C to 150°C). However, the DMP6250SE-13 uses SOT-223-3 packaging (three pins) versus the original SOT-223-4 (four pins). Verify that your PCB layout and circuit design do not require the fourth Drain pin connection before substitution.

Q: What is the inventory status of each substitute part?

A: BSP170PH6327XTSA1: 16,978 pcs; DMP6250SE-13: 23,500 pcs; NDT2955: 41,100 pcs; ZXMP6A13GTA: 15,465 pcs. All parts are available as New Original stock. The NDT2955 offers the highest inventory availability.

Q: Are there any thermal performance differences between the substitutes?

A: Yes. The DMP6250SE-13 offers enhanced thermal performance with 14W power dissipation at Tc (case temperature), compared to 1.8W Ta for most other parts. The NDT2955 provides 3W Ta power dissipation. For applications with significant thermal constraints, DMP6250SE-13 or NDT2955 are recommended.
