IRLR210ATM N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRLR210ATM is an N-Channel MOSFET manufactured by onsemi, rated for 200V drain-to-source voltage with 2.7A continuous drain current at 25°C. The device is housed in a TO-252AA (DPAK) surface mount package and is classified as obsolete. Due to its obsolete status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production and field replacements.

Substitute Part Grouping Explanation

Substitution of the IRLR210ATM is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 200V minimum
• Mounting Type: Surface Mount
• Package / Case: TO-252-3, DPAK (2 Leads + Tab), SC-63

Performance Compatibility Criteria:

• Continuous Drain Current (Id) @ 25°C: Equal to or greater than 2.7A
• Rds On (Max): Equal to or less than 1.5 Ohm (at specified gate voltage)
• Operating Temperature Range: Minimum -55°C to 150°C
• Power Dissipation: Sufficient thermal capability for application requirements

The substitute parts FQD4N20TM and AOD4504 meet all mandatory matching criteria and provide equal or superior performance characteristics across the specified parameters.

Engineering Selection Recommendations

FQD4N20TM (Fairchild Semiconductor)

The FQD4N20TM is an active product with electrical characteristics closely aligned to the IRLR210ATM. It provides 3A continuous drain current, exceeding the original 2.7A specification, and maintains equivalent Rds On performance at 1.4 Ohm. The device operates across the same temperature range (-55°C to 150°C) and is housed in the identical TO-252 DPAK package. This substitute is suitable for direct replacement in applications where the original onsemi part is no longer available. The FQD4N20TM carries ECCN EAR99 classification and is compliant with applicable export regulations.

AOD4504 (Alpha & Omega Semiconductor Inc.)

The AOD4504 is an active product offering superior electrical performance with 6A continuous drain current and significantly lower Rds On of 0.4 Ohm at 3A, 10V. This device provides enhanced thermal capability with 42.5W maximum power dissipation at Tc, compared to 21W for the original part. The AOD4504 extends the operating temperature range to 175°C and is housed in the identical TO-252 DPAK package. This substitute is suitable for applications requiring higher current handling or improved thermal performance. The AOD4504 is RoHS3 compliant and carries ECCN EAR99 classification.

Both substitute parts are electrically and mechanically compatible with the IRLR210ATM and are available from active manufacturers, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the FQD4N20TM or AOD4504 be used as direct pin-for-pin replacements for the IRLR210ATM?

A: Yes. Both substitute parts are housed in the TO-252-3 DPAK package with identical pinout and lead configuration. No PCB modifications are required for substitution.

Q: What are the key differences between the FQD4N20TM and AOD4504?

A: The FQD4N20TM provides 3A continuous drain current with 1.4 Ohm Rds On, closely matching the original IRLR210ATM performance. The AOD4504 offers higher current capability at 6A with significantly lower Rds On of 0.4 Ohm, resulting in reduced power dissipation and improved thermal performance. The AOD4504 also extends the operating temperature range to 175°C.

Q: Which substitute should be selected for a direct performance match?

A: The FQD4N20TM provides the closest electrical performance match to the IRLR210ATM, with comparable current ratings and Rds On characteristics. Selection of the AOD4504 is appropriate when higher current capacity or improved thermal performance is beneficial to the application.

Q: Are there any gate drive voltage differences between the original and substitute parts?

A: The IRLR210ATM specifies a 5V drive voltage for maximum Rds On rating. The FQD4N20TM and AOD4504 specify 10V drive voltage. Both devices operate at 5V gate voltage; however, Rds On values are specified at their respective drive voltages. Circuit design should account for the gate drive voltage available in the application.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: The FQD4N20TM is supplied in bulk packaging. The AOD4504 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Are the substitute parts compliant with export regulations?

A: Both FQD4N20TM and AOD4504 carry ECCN EAR99 classification, consistent with the original IRLR210ATM. Both are subject to the same export control regulations.
