Substitute Part Grouping Explanation

Substitution of N-Channel MOSFETs is determined by compatibility across the following critical parameters:

Voltage Rating Compatibility: The drain-to-source voltage (Vdss) must equal or exceed the main part specification. Substitute parts with higher voltage ratings (40V) are acceptable for 30V applications.

Current Handling Capability: The continuous drain current (Id) at 25°C must meet or exceed the application requirement. Substitutes with equal or higher current ratings maintain functional equivalence.

On-Resistance (Rds On): Lower on-resistance values indicate improved efficiency and reduced power dissipation. Substitutes with comparable or lower Rds On values are electrically compatible.

Package and Pinout: All substitute parts must use identical D2PAK (TO-263-3) surface mount packaging with matching lead configuration to ensure mechanical and electrical compatibility without PCB redesign.

Gate Drive Voltage: Drive voltage specifications (4.5V and 10V) must be compatible with existing gate drive circuitry. All listed substitutes maintain this compatibility.

Temperature Range: Operating temperature specifications must encompass the application environment. All substitutes support the -55°C to 175°C range or equivalent.

Compliance and Product Status: RoHS compliance and product status (Active, Not For New Designs, or Obsolete) inform long-term availability and regulatory requirements.

Engineering Selection Recommendations

Primary Substitute: PSMN4R3-30BL,118

The PSMN4R3-30BL,118 from Nexperia is the recommended primary substitute. It maintains identical 30V voltage rating and D2PAK packaging. With 100A continuous drain current, it provides 86% of the main part's current capability while delivering superior on-resistance performance (4.1 mOhm versus 7 mOhm). The device is classified as Active, ensuring long-term availability and supply chain stability. ROHS3 compliance satisfies modern regulatory requirements. This substitute is suitable for applications where the full 116A capability is not required or where improved efficiency is beneficial.

Secondary Substitute: STB80NF03L-04T4

The STB80NF03L-04T4 from STMicroelectronics offers 80A continuous drain current with superior on-resistance (4 mOhm) and exceptional power dissipation capability (300W). The 30V voltage rating and D2PAK package ensure direct compatibility. This device is classified as Obsolete but maintains ROHS3 compliance. Selection of this substitute is appropriate for applications requiring maximum thermal performance and lower conduction losses, provided that 80A current capacity is sufficient.

Alternative Substitute: IPB015N04LGATMA1

The IPB015N04LGATMA1 from Infineon provides the highest current capability (120A) and superior on-resistance (1.5 mOhm). The 40V voltage rating exceeds the main part specification, providing additional design margin. D2PAK packaging ensures mechanical compatibility. This device is classified as Not For New Designs, indicating limited future availability. Selection is appropriate for applications requiring maximum current handling and efficiency, with the understanding that long-term supply may be constrained.

Not Recommended: PSMN017-30BL,118

The PSMN017-30BL,118 provides only 32A continuous drain current, representing 28% of the main part's capability. While it maintains 30V voltage rating and D2PAK packaging, the significantly reduced current capacity limits its applicability to lower-power variants of the original design. This substitute is suitable only for applications where current requirements have been substantially reduced.

Frequently Asked Questions (FAQ)

Q: Can I use the IPB015N04LGATMA1 as a direct replacement for the 94-2113?

A: Yes, the IPB015N04LGATMA1 is electrically compatible. It provides higher current capability (120A versus 116A), superior on-resistance (1.5 mOhm versus 7 mOhm), and higher voltage rating (40V versus 30V). The D2PAK package is identical, requiring no PCB modifications. However, this device is classified as Not For New Designs, which may affect long-term supply availability.

Q: What is the difference between the PSMN4R3-30BL,118 and STB80NF03L-04T4?

A: Both devices maintain the 30V voltage rating and D2PAK package. The PSMN4R3-30BL,118 provides 100A current with 4.1 mOhm on-resistance and is classified as Active. The STB80NF03L-04T4 provides 80A current with 4 mOhm on-resistance and is classified as Obsolete. The PSMN4R3-30BL,118 is preferred for new designs due to Active status and higher current capability.

Q: Why is the PSMN017-30BL,118 listed as a substitute if it has only 32A capability?

A: The PSMN017-30BL,118 is listed because it maintains the 30V voltage rating and D2PAK package, satisfying the core substitution criteria. However, its 32A current rating represents a significant reduction from the main part's 116A specification. This substitute is applicable only to applications where current requirements have been substantially reduced or where the original design operated well below the 116A maximum.

Q: Are all substitute parts available in the same packaging?

A: Yes, all substitute parts listed use D2PAK (TO-263-3) surface mount packaging with identical pinout. No PCB modifications are required for mechanical compatibility. All devices support the same drive voltage specifications (4.5V and 10V).

Q: What is the impact of different on-resistance values on my application?

A: On-resistance (Rds On) directly affects conduction losses and heat generation. Lower on-resistance values reduce power dissipation. The IPB015N04LGATMA1 (1.5 mOhm) dissipates significantly less heat than the main part (7 mOhm). The PSMN4R3-30BL,118 (4.1 mOhm) and STB80NF03L-04T4 (4 mOhm) provide intermediate performance. Selection depends on thermal management requirements and efficiency targets.

Q: Which substitute has the best long-term availability?

A: The PSMN4R3-30BL,118 is classified as Active, indicating ongoing production and the longest expected availability. The IPB015N04LGATMA1 is classified as Not For New Designs, suggesting limited future availability. The STB80NF03L-04T4 and PSMN017-30BL,118 are classified as Obsolete, indicating no new production.

Q: Do all substitutes meet RoHS compliance requirements?

A: All substitute parts are ROHS3 compliant. The main part (94-2113) is RoHS non-compliant. If RoHS compliance is a regulatory requirement, any of the listed substitutes satisfy this requirement.

Q: Can I use a substitute with higher voltage rating (40V) in a 30V application?

A: Yes, the IPB015N04LGATMA1 with 40V rating is suitable for 30V applications. Higher voltage ratings provide additional design margin and do not create compatibility issues. The device will operate safely within the 30V specification.

Q: What is the significance of gate charge (Qg) differences between parts?

A: Gate charge affects gate drive circuit requirements and switching speed. Higher gate charge values require more drive current or longer switching times. The PSMN017-30BL,118 (10.7 nC) has the lowest gate charge, while the IPB015N04LGATMA1 (346 nC) has the highest. For most applications with standard gate drive circuits, these differences are not critical, but high-frequency switching applications may require evaluation.
