Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

IRFR2407TRPBF is the primary direct substitute for IRFR2407TRLPBF. Both parts share identical electrical specifications (75V, 42A, 26mOhm Rds On) and package configuration. IRFR2407TRPBF carries Active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected.

For Enhanced Voltage Margin Applications:

IPD35N10S3L26ATMA1 and IPD30N10S3L34ATMA1 are Infineon OptiMOS™ series parts rated at 100V Vdss. IPD35N10S3L26ATMA1 delivers 35A continuous drain current with 24mOhm Rds On at 35A/10V, providing superior on-state resistance compared to the original 26mOhm specification. Both parts are Active status with extensive inventory availability. These substitutes are suitable for applications requiring higher voltage headroom while maintaining comparable thermal performance.

For Current-Limited Applications:

STD25NF10LT4, STD25NF10T4, and STD26NF10 are STMicroelectronics STripFET™ II series parts rated at 100V with 25A continuous drain current. These parts are appropriate for designs where the 42A rating of the original part exceeds application requirements. All three maintain Active product status and ROHS3 compliance.

For Lower Voltage, Higher Current Capability:

STD30NF06LT4 (60V, 35A) and FDD10AN06A0 (60V, 50A) provide reduced voltage ratings with enhanced current handling. FDD10AN06A0 offers the lowest on-state resistance (10.5mOhm @ 50A/10V) among all listed substitutes. These parts are suitable only for applications where 60V or 55V Vdss ratings are acceptable.

Obsolete Part Considerations:

BUK9226-75A,118 (Nexperia TrenchMOS™) matches the 75V/45A specification but carries Obsolete product status. This part should not be selected for new designs despite electrical compatibility.

Frequently Asked Questions (FAQ)

Q1: Can IRFR2407TRPBF directly replace IRFR2407TRLPBF without circuit modification?

A: Yes. IRFR2407TRPBF is a parametric equivalent with identical electrical specifications and package configuration. No circuit modifications are required. The only difference is product status (Active vs. Obsolete) and packaging format (Digi-Reel vs. standard tape).

Q2: What is the primary advantage of substituting with IPD35N10S3L26ATMA1?

A: IPD35N10S3L26ATMA1 provides 100V Vdss rating compared to 75V, offering 33% higher voltage margin. On-state resistance improves to 24mOhm at 35A/10V. The part is Active status with high inventory availability. This substitute is recommended for applications requiring enhanced voltage headroom or improved thermal efficiency.

Q3: Are STD25NF10LT4 and STD25NF10T4 interchangeable?

A: Both parts are electrically equivalent at 100V/25A with identical package configuration. STD25NF10LT4 features lower Rds On (35mOhm @ 12.5A/10V) and lower gate threshold voltage (2.5V), while STD25NF10T4 has higher Rds On (38mOhm) and higher gate threshold (4V). Selection depends on specific gate drive and thermal requirements. Both are Active status.

Q4: Can FDD10AN06A0 be used in applications originally designed for IRFR2407TRLPBF?

A: FDD10AN06A0 is suitable only if the application can tolerate 60V maximum Vdss (compared to 75V) and does not require 42A continuous drain current. The part offers superior on-state resistance (10.5mOhm) and higher power dissipation capability (135W). Circuit validation is required to confirm voltage margin adequacy.

Q5: What packaging considerations apply when substituting these parts?

A: All listed substitutes use TO-252-3 (DPAK) surface mount package with identical footprint and lead configuration. PCB layout modifications are not required. Verify supplier device package designation matches PG-TO252-3-11 or equivalent to ensure mechanical compatibility.

Q6: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements.

Q7: Which substitute offers the lowest on-state resistance?

A: FDD10AN06A0 provides the lowest on-state resistance at 10.5mOhm @ 50A/10V. However, this part is rated at 60V Vdss, which may not be suitable for all applications. Among 75V-rated parts, BUK9226-75A,118 offers 24.6mOhm @ 25A/10V, though it carries Obsolete status.

Q8: What is the difference between Infineon HEXFET® and OptiMOS™ series?

A: HEXFET® (IRFR2407 series) represents earlier generation technology. OptiMOS™ (IPD series) represents current generation with improved gate charge characteristics and lower threshold voltages. OptiMOS™ parts are recommended for new designs due to Active product status and superior performance metrics.
