Engineering Selection Recommendations

IRLR8726TRPBF (Infineon Technologies) - Recommended Primary Substitute

The IRLR8726TRPBF is the optimal substitute for the IRLR8726TRLPBF. This part is manufactured by the same supplier (Infineon Technologies) and maintains identical electrical specifications across all critical parameters: 30V Vdss, 86A continuous drain current, 5.8mOhm Rds On, and 75W power dissipation. The package type is identical (TO-252-3 DPAK), enabling direct PCB replacement without layout modifications. The IRLR8726TRPBF carries an "Active" product status, ensuring long-term availability and supply chain stability. Both parts share the same HEXFET® series designation, gate charge characteristics (23nC @ 4.5V), and operating temperature range (-55°C to 175°C). RoHS3 compliance and MSL 1 rating are maintained. This part is suitable for all applications currently using the IRLR8726TRLPBF.

STD100N3LF3 (STMicroelectronics) - Secondary Substitute with Considerations

The STD100N3LF3 meets the primary electrical requirements with 30V Vdss and 80A continuous drain current, which approaches the 86A specification of the main part. The on-resistance of 5.5mOhm @ 40A, 10V is superior to the main part's 5.8mOhm specification. Package compatibility is maintained with TO-252-3 DPAK configuration. However, this part carries an "Obsolete" product status, indicating discontinued manufacturing and potential supply constraints. The operating temperature range (-55°C to 175°C) and RoHS3 compliance are equivalent. Gate charge is slightly elevated at 27nC @ 5V compared to 23nC @ 4.5V for the main part. This substitute is acceptable for replacement applications where supply of the primary substitute is unavailable, but long-term availability cannot be assured.

PJD80N03_L2_00001 (Panjit International Inc.) - Functional Substitute with Limitations

The PJD80N03_L2_00001 provides functional equivalence with 30V Vdss and 80A continuous drain current at case temperature. The on-resistance of 6.0mOhm @ 20A, 10V is within acceptable tolerance of the main part. Package type is TO-252, maintaining mechanical compatibility with TO-252-3 DPAK footprint. The part carries "Active" product status with confirmed inventory availability. However, the maximum operating temperature is limited to 150°C (junction temperature), which is 25°C below the main part's 175°C specification. This temperature limitation may restrict use in high-temperature applications. Gate charge is significantly reduced at 12nC @ 4.5V, which may affect switching characteristics in certain circuit topologies. This substitute is suitable for applications operating within the -55°C to 150°C range.

PSMN7R0-60YS,115 (Nexperia USA Inc.) - Functional Equivalent with Package Change

The PSMN7R0-60YS,115 exceeds the electrical requirements with 60V Vdss (double the main part specification) and 89A continuous drain current. The on-resistance of 6.4mOhm @ 15A, 10V is marginally higher than the main part. Power dissipation capability is enhanced at 117W. Operating temperature range (-55°C to 175°C) matches the main part. However, this part utilizes LFPAK56 / Power-SO8 package (SC-100, SOT-669), which differs from the TO-252-3 DPAK package of the main part. PCB layout redesign is required for implementation. Gate charge is elevated at 45nC @ 10V, indicating different switching dynamics. This substitute is suitable only for applications where package redesign is feasible and the higher voltage rating provides system-level benefits.

Frequently Asked Questions (FAQ)

Q1: Can the IRLR8726TRPBF be used as a direct replacement for the IRLR8726TRLPBF without PCB modifications?

A: Yes. The IRLR8726TRPBF is a direct replacement. Both parts share identical electrical specifications (30V, 86A, 5.8mOhm Rds On, 75W power dissipation) and the same TO-252-3 DPAK package footprint. No PCB layout changes are required. The primary advantage of the IRLR8726TRPBF is its "Active" product status, ensuring continued availability compared to the "Not For New Designs" status of the IRLR8726TRLPBF.

Q2: What is the significance of the "Not For New Designs" product status on the IRLR8726TRLPBF?

A: "Not For New Designs" indicates that Infineon has discontinued this part for new applications and is transitioning customers to alternative products. While existing inventory may remain available, the manufacturer does not guarantee long-term supply or support. For new designs or replacement applications, the IRLR8726TRPBF (Active status) is the recommended alternative.

Q3: Can the STD100N3LF3 be substituted if the IRLR8726TRPBF is unavailable?

A: The STD100N3LF3 is functionally acceptable with 30V Vdss and 80A continuous drain current, meeting the primary electrical requirements. However, this part carries "Obsolete" status, indicating discontinued manufacturing. While it may be available from inventory, supply cannot be assured. Use this substitute only when the primary substitute (IRLR8726TRPBF) is unavailable and the application timeline permits sourcing from remaining stock.

Q4: What are the key differences between the PJD80N03_L2_00001 and the main part?

A: The PJD80N03_L2_00001 maintains 30V Vdss and provides 80A continuous drain current (6A below the main part's 86A). The maximum operating temperature is limited to 150°C versus 175°C for the main part. Gate charge is significantly lower at 12nC, which may affect switching speed in certain applications. This part is suitable for applications operating within the -55°C to 150°C temperature range where the reduced current rating is acceptable.

Q5: Why does the PSMN7R0-60YS,115 have a different package than the main part?

A: The PSMN7R0-60YS,115 uses LFPAK56 / Power-SO8 package (SC-100, SOT-669) instead of TO-252-3 DPAK. This package change reflects different thermal and electrical design objectives by Nexperia. The LFPAK56 package provides enhanced thermal performance suitable for higher power applications. Substitution requires PCB layout redesign to accommodate the different footprint and pin configuration.

Q6: Is the higher voltage rating (60V) of the PSMN7R0-60YS,115 a disadvantage compared to the 30V main part?

A: The higher voltage rating is not a disadvantage; it provides additional design margin. A 60V-rated device can be used in 30V applications without performance degradation. The higher voltage rating may offer system-level benefits such as improved transient immunity or simplified power supply design. However, the different package requires PCB redesign, which may offset these benefits in retrofit applications.

Q7: What compliance certifications are maintained across all substitute parts?

A: All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the main part. REACH status is "Unaffected" for all parts. ECCN classification is EAR99 and HTSUS code is 8541.29.0095 across all parts. These certifications ensure regulatory compliance for industrial and commercial applications.

Q8: How should gate charge differences affect circuit design when substituting parts?

A: Gate charge (Qg) differences affect the speed and energy required to switch the MOSFET. The main part specifies 23nC @ 4.5V. The STD100N3LF3 has 27nC @ 5V (slightly higher), the PJD80N03_L2_00001 has 12nC @ 4.5V (significantly lower), and the PSMN7R0-60YS,115 has 45nC @ 10V (substantially higher). Lower gate charge enables faster switching and reduced driver power consumption. Higher gate charge requires stronger gate drive capability. Verify that the gate driver circuit can supply the required charge for the selected substitute part.

Q9: Can the PJD80N03_L2_00001 be used in applications requiring operation above 150°C?

A: No. The PJD80N03_L2_00001 has a maximum junction temperature rating of 150°C, which is 25°C below the main part's 175°C specification. Applications requiring operation above 150°C must use the IRLR8726TRPBF, STD100N3LF3, or PSMN7R0-60YS,115, all of which support -55°C to 175°C operation.

Q10: What inventory considerations should guide substitute part selection?

A: The IRLR8726TRPBF has the highest confirmed inventory (864,118 pcs) with "Active" status, ensuring supply availability. The PSMN7R0-60YS,115 has 59,791 pcs available. The PJD80N03_L2_00001 has limited inventory at 1,040 pcs. The STD100N3LF3 has 15,465 pcs but carries "Obsolete" status. For applications requiring immediate availability and long-term supply assurance, the IRLR8726TRPBF is the optimal choice.
