NDT454P P-Channel MOSFET 30V 5.9A Equivalent & Substitute Parts

Part Overview

The NDT454P is a P-Channel metal oxide semiconductor field-effect transistor (MOSFET) manufactured by onsemi, rated for 30V drain-to-source voltage with a continuous drain current of 5.9A at 25°C. The device is housed in a SOT-223-4 surface mount package and dissipates a maximum of 3W. The NDT454P is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and component procurement. Substitute parts must maintain compatibility with the electrical specifications and mechanical form factor while considering current product availability and status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NDT454P is determined by the following critical parameters: P-Channel FET type, 30V Vdss rating, SOT-223-4 surface mount package, and electrical performance characteristics including continuous drain current, on-resistance, and gate charge. Substitute parts must maintain compatibility across these dimensions to ensure functional equivalence in circuit applications.

The substitute parts are grouped into two categories based on electrical performance alignment:

Category 1: High Current Performance (≥5A) Parts in this category maintain drain current ratings at or above 5A, supporting applications requiring the full current capacity of the NDT454P. These include NDT452AP (5A), ZXMP3A16GTA (5.4A), and the original NDT454P specification (5.9A).

Category 2: Reduced Current Performance (<5A) Parts in this category provide lower continuous drain current ratings (3A to 3.7A) and are suitable for applications with reduced current requirements. These include NTF5P03T3G (3.7A), BSP250,115 (3A), and BSP250,135 (3A).

All substitute parts maintain the 30V Vdss rating, SOT-223 package family compatibility, and surface mount technology. Compliance certifications (RoHS3, REACH Unaffected, MSL 1) are consistent across all listed parts.

Engineering Selection Recommendations

For Direct Replacement (Highest Compatibility)

The NDT452AP is the recommended primary substitute for the NDT454P. Both parts are manufactured by onsemi, share identical 30V Vdss and 3W power dissipation ratings, and are housed in the SOT-223-4 package. The NDT452AP is currently in active product status, ensuring long-term availability. The continuous drain current is reduced from 5.9A to 5A, and on-resistance increases from 50mOhm to 65mOhm at rated conditions. These differences are acceptable for applications not requiring the full current capacity of the original part. The NDT452AP maintains the same operating temperature range (-65°C to 150°C) and compliance certifications as the NDT454P.

For High Current Applications

The ZXMP3A16GTA, manufactured by Diodes Incorporated, provides 5.4A continuous drain current, closely matching the NDT454P specification of 5.9A. This part features superior on-resistance performance at 45mOhm (compared to 50mOhm for the NDT454P) and is currently in active product status. The ZXMP3A16GTA is housed in a SOT-223-3 package, which is mechanically compatible with SOT-223-4 applications. Power dissipation is rated at 2W, which is lower than the NDT454P's 3W rating. The operating temperature range extends from -55°C to 150°C, providing adequate thermal performance for most applications.

For Reduced Current Applications

The NTF5P03T3G, also manufactured by onsemi, is suitable for applications requiring 3.7A or less. This part maintains the 30V Vdss rating and is in active product status. The on-resistance of 100mOhm is higher than the NDT454P, and power dissipation is limited to 1.56W. The operating temperature range is -55°C to 150°C. This part is appropriate for lower-power switching applications where current requirements do not exceed 3.7A.

Parts Not Recommended for New Designs

The BSP250,115 and BSP250,135 parts, manufactured by Nexperia USA Inc., are designated as "Not For New Designs." While these parts maintain 30V Vdss and 3A continuous drain current ratings, their obsolescence status makes them unsuitable for new product development. These parts are retained in the substitute list for legacy system support only.

Frequently Asked Questions (FAQ)

Q: Can the NDT454P be directly replaced with the NDT452AP?

A: Yes. The NDT452AP is the recommended substitute for the NDT454P. Both parts are onsemi P-Channel MOSFETs rated for 30V with 3W power dissipation in SOT-223-4 packages. The primary difference is the continuous drain current rating: NDT452AP provides 5A compared to the NDT454P's 5.9A. For applications requiring less than 5A, the NDT452AP is a direct functional replacement. Verify that your circuit design does not require the additional 0.9A capacity of the original part.

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

A: SOT-223-4 and SOT-223-3 are both surface mount packages in the SOT-223 family with identical mechanical footprints and pin spacing. The primary difference is the number of leads: SOT-223-4 includes four leads (Gate, Drain, Source, and an additional pin), while SOT-223-3 includes three leads (Gate, Drain, Source). For MOSFET applications, both packages are mechanically compatible on standard PCB layouts. Verify pin assignments in the device datasheet before substitution.

Q: Why is the ZXMP3A16GTA listed as a substitute if it has lower power dissipation?

A: The ZXMP3A16GTA is listed as a substitute because it maintains the critical electrical parameters for P-Channel MOSFET operation: 30V Vdss, 5.4A continuous drain current (close to the NDT454P's 5.9A), and superior on-resistance performance (45mOhm vs. 50mOhm). The lower power dissipation rating (2W vs. 3W) reflects the device's thermal characteristics under specified test conditions and does not indicate reduced functionality. The ZXMP3A16GTA is suitable for applications where the NDT454P's full 3W dissipation capacity is not required.

Q: Can I use BSP250,115 or BSP250,135 in new designs?

A: No. Both BSP250,115 and BSP250,135 are designated as "Not For New Designs" by Nexperia USA Inc. These parts are retained in the substitute list for legacy system support and repair applications only. For new product development, select from parts with active product status: NDT452AP, NTF5P03T3G, or ZXMP3A16GTA.

Q: What are the key parameters I should verify when substituting the NDT454P?

A: The critical parameters for substitution are: (1) P-Channel FET type, (2) 30V Vdss rating, (3) continuous drain current requirement (verify your circuit operates at or below the substitute part's rated current), (4) on-resistance performance (lower on-resistance reduces power loss), (5) SOT-223 package family compatibility, and (6) operating temperature range (-55°C to 150°C minimum for most applications). Verify gate threshold voltage and gate charge specifications if your circuit uses specific drive voltage levels.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed—NDT452AP, NTF5P03T3G, BSP250,115, BSP250,135, and ZXMP3A16GTA—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. All parts are REACH Unaffected and classified under ECCN EAR99 for export purposes.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are as follows: NDT452AP (40,700 pcs), NTF5P03T3G (15,365 pcs), BSP250,115 (25,086 pcs), BSP250,135 (116,207 pcs), and ZXMP3A16GTA (24,400 pcs). Inventory levels are subject to change. Verify current availability with your component supplier before finalizing procurement decisions.
