NTD95N02RG Equivalent & Substitute Parts

Part Overview

The NTD95N02RG is an N-Channel MOSFET manufactured by onsemi, rated for 24V drain-to-source voltage with 12A continuous drain current (Ta) and 32A (Tc). The device is housed in a DPAK surface mount package and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system maintenance. Substitute devices must maintain functional compatibility within the electrical and mechanical constraints of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NTD95N02RG is determined by the following critical parameters:

Electrical Compatibility Criteria:

• FET Type: N-Channel MOSFET (Metal Oxide technology)
• Drain-to-Source Voltage (Vdss): Substitute must equal or exceed 24V
• Continuous Drain Current (Id): Substitute must support minimum 12A (Ta) or 32A (Tc) rating
• Gate Threshold Voltage (Vgs(th)): Must be compatible with 2V maximum specification
• Rds On (Max): Lower or equal on-resistance values indicate improved performance
• Operating Temperature Range: Must support -55°C to 150°C minimum

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package / Case: DPAK (TO-252-3, SC-63) form factor required for PCB layout compatibility

Compliance Criteria:

• Moisture Sensitivity Level (MSL): Level 1 (Unlimited) required
• ECCN and HTSUS classifications must align for regulatory compliance

The substitute parts listed below satisfy these criteria with varying performance enhancements and compliance certifications.

Engineering Selection Recommendations

STD95N2LH5 (STMicroelectronics) – Primary Substitute

The STD95N2LH5 is the preferred substitute for the NTD95N02RG. This device is classified as Active with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The STD95N2LH5 provides superior electrical performance with 80A continuous drain current (Tc), significantly exceeding the original 32A (Tc) specification. The on-resistance of 4.5 mOhm at 40A, 10V is lower than the original 5 mOhm, resulting in reduced power dissipation and improved thermal efficiency. The drain-to-source voltage rating of 25V exceeds the 24V requirement with minimal margin, maintaining design safety. The extended operating temperature range of -55°C to 175°C provides additional thermal headroom. DPAK packaging and MSL Level 1 rating ensure direct PCB compatibility. REACH compliance status is unaffected, supporting global supply chain requirements.

IRLR024 (Vishay Siliconix) – Secondary Substitute

The IRLR024 is an Active product suitable for applications where higher voltage margin is required. With a 60V Vdss rating, this device provides substantial overvoltage protection compared to the 24V original specification. However, the continuous drain current of 14A (Tc) is lower than the original 32A (Tc), limiting its use to lower-current applications. The on-resistance of 100 mOhm at 8.4A, 5V is significantly higher than the original specification, resulting in increased power dissipation and thermal stress. The gate charge of 18 nC and input capacitance of 870 pF are lower than the original, reducing switching losses. DPAK packaging and MSL Level 1 rating provide mechanical compatibility. The device is RoHS non-compliant, which may restrict use in regulated applications. This substitute is suitable only for applications where current requirements are below 14A and RoHS compliance is not mandated.

Product Status Consideration

Both substitute parts are classified as Active, ensuring continued manufacturing support and supply chain availability. The original NTD95N02RG is obsolete and should not be specified for new designs.

Frequently Asked Questions (FAQ)

Q: Can the STD95N2LH5 directly replace the NTD95N02RG without PCB modifications?

A: Yes. Both devices use identical DPAK (TO-252-3, SC-63) packaging with the same pin configuration and footprint. No PCB layout changes are required. The STD95N2LH5 is a direct mechanical and electrical substitute.

Q: What is the primary advantage of the STD95N2LH5 over the original NTD95N02RG?

A: The STD95N2LH5 offers significantly higher continuous drain current (80A vs. 32A at Tc), lower on-resistance (4.5 mOhm vs. 5 mOhm), and Active product status with ROHS3 compliance. These characteristics provide improved performance, reduced thermal dissipation, and long-term supply availability.

Q: Why is the IRLR024 not recommended as a primary substitute?

A: The IRLR024 has a lower continuous drain current rating (14A vs. 32A at Tc) and significantly higher on-resistance (100 mOhm vs. 5 mOhm), making it unsuitable for applications requiring the original current capacity. Additionally, it is RoHS non-compliant, which may conflict with regulatory requirements in many applications.

Q: Are there thermal performance differences between the substitutes?

A: Yes. The STD95N2LH5 has a maximum power dissipation of 70W (Tc), compared to the original 86W (Tc). The lower on-resistance of the STD95N2LH5 results in reduced I²R losses at equivalent current levels. The IRLR024 has a maximum power dissipation of 42W (Tc), but its higher on-resistance (100 mOhm) results in greater power dissipation at higher currents, offsetting the lower absolute rating.

Q: What is the operating temperature range difference?

A: The STD95N2LH5 supports -55°C to 175°C (TJ), extending 25°C above the original NTD95N02RG specification of -55°C to 150°C (TJ). This provides additional thermal margin for high-temperature applications. The IRLR024 matches the original range at -55°C to 150°C (TJ).

Q: Are gate drive voltage requirements compatible?

A: The STD95N2LH5 has a gate threshold voltage (Vgs(th)) of 1V maximum at 250µA, compared to the original 2V maximum. This lower threshold voltage indicates faster switching response and reduced gate drive requirements. The IRLR024 matches the original 2V specification. Both devices are compatible with standard gate drive circuits designed for the original part.

Q: What is the significance of MSL Level 1 rating for all three devices?

A: MSL Level 1 (Unlimited) indicates that these devices have unlimited shelf life and do not require moisture-controlled storage or baking procedures before soldering. This simplifies inventory management and reduces handling costs compared to higher MSL-rated components.

Q: Can the IRLR024 be used in high-current applications?

A: No. The IRLR024 is rated for 14A continuous drain current (Tc), which is below the original 32A (Tc) specification. Using this device in applications requiring currents above 14A will result in thermal stress, reduced reliability, and potential device failure.

Q: What compliance certifications should be verified for regulatory applications?

A: The STD95N2LH5 is ROHS3 compliant and REACH unaffected, meeting EU regulatory requirements. The IRLR024 is RoHS non-compliant and should not be used in applications subject to RoHS directives. Both devices carry EAR99 ECCN and 8541.29.0095 HTSUS classifications for export control purposes.
