Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Full Electrical & Voltage Compatibility):

The following parts provide direct substitution with matching or superior electrical performance and identical voltage ratings:

IRF1407STRLPBF (Infineon Technologies HEXFET® Series): This part matches the 2SK4065-DL-E in 75V Vdss rating and 100A continuous drain current specification. The IRF1407STRLPBF is active and ROHS3 compliant. Gate charge is slightly elevated at 250nC compared to 220nC, but on-resistance is comparable at 7.8mOhm. Operating temperature range extends to 175°C, exceeding the 2SK4065-DL-E specification. Packaging is identical TO-263-3 D2PAK.

IRFS3307ZTRLPBF and IRFS3307ZTRRPBF (Infineon Technologies HEXFET® Series): Both variants provide 75V Vdss with enhanced 120A continuous drain current (Tc). Gate charge is reduced to 110nC, and on-resistance is improved to 5.8mOhm at 75A. These parts are active and ROHS3 compliant with extended operating temperature to 175°C. The primary difference between ZTRLPBF (Cut Tape & Digi-Reel) and ZTRRPBF (Tape & Reel) is packaging format only; electrical specifications are identical.

FDB060AN08A0 (onsemi PowerTrench® Series): This part maintains 75V Vdss rating with 80A continuous drain current (Tc) and 16A at Ta. On-resistance is matched at 6mOhm. Gate charge is significantly reduced to 95nC, reducing drive circuit demands. The device is active and ROHS3 compliant with extended operating temperature to 175°C. Input capacitance is substantially lower at 5150pF, improving switching efficiency. Packaging is identical TO-263 D2PAK.

Secondary Substitute (Reduced Voltage Rating):

STB100N6F7 (STMicroelectronics STripFET™ F7 Series): This part provides 60V Vdss, which is 15V below the 2SK4065-DL-E specification. It matches 100A continuous drain current (Tc) and provides superior on-resistance at 5.6mOhm. Gate charge is significantly reduced to 30nC, and input capacitance is lowest among all alternatives at 1980pF. The device is active and ROHS3 compliant with extended operating temperature to 175°C. This part is suitable only for applications where the 60V voltage rating is sufficient and does not exceed system requirements.

Compliance & Regulatory Status:

All substitute parts carry REACH Unaffected status, EAR99 ECCN classification, and 8541.29.0095 HTSUS code, matching the regulatory profile of the 2SK4065-DL-E. All active substitutes are ROHS3 compliant. Moisture sensitivity level is uniformly rated at MSL 1 (Unlimited) across all parts.

Frequently Asked Questions (FAQ)

Q: Can the FDB060AN08A0 replace the 2SK4065-DL-E in all applications?

A: The FDB060AN08A0 is electrically compatible with matching 75V Vdss and 6mOhm on-resistance. However, continuous drain current at Ta is specified as 16A versus the 2SK4065-DL-E at 100A. At Tc (case temperature), the FDB060AN08A0 supports 80A. Application suitability depends on whether your design operates at Ta or Tc conditions and whether 80A or 100A current capacity is required.

Q: What is the difference between IRFS3307ZTRLPBF and IRFS3307ZTRRPBF?

A: Both parts are electrically identical with 75V Vdss, 120A continuous drain current, 5.8mOhm on-resistance, and 110nC gate charge. The difference is packaging format only: ZTRLPBF is supplied in Cut Tape (CT) & Digi-Reel format, while ZTRRPBF is supplied in standard Tape & Reel (TR) format. Select based on your procurement and assembly process requirements.

Q: Why does STB100N6F7 have a lower Vdss rating of 60V?

A: The STB100N6F7 is designed for lower voltage applications. A 60V rating is sufficient for many industrial and consumer switching applications but does not provide the 75V margin of the 2SK4065-DL-E. Use STB100N6F7 only if your circuit operates at voltages below 60V and does not require the additional voltage headroom.

Q: Are all substitute parts available in the same TO-263-3 D2PAK package?

A: Yes. All substitute parts listed are housed in TO-263-3, D2PAK (2 Leads + Tab), or TO-263AB package variants. Mechanical footprint and pin configuration are identical, allowing direct PCB layout compatibility without redesign.

Q: Which substitute offers the lowest gate charge?

A: The STB100N6F7 has the lowest gate charge at 30nC @ 10V, followed by FDB060AN08A0 at 95nC. Lower gate charge reduces driver circuit power consumption and switching losses. However, STB100N6F7 has a reduced 60V Vdss rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts (FDB060AN08A0, IRF1407STRLPBF, IRFS3307ZTRLPBF, IRFS3307ZTRRPBF, and STB100N6F7) are ROHS3 compliant. The 2SK4065-DL-E is obsolete and does not carry a stated RoHS status.

Q: What is the operating temperature range difference?

A: The 2SK4065-DL-E specifies a maximum junction temperature (TJ) of 150°C. All active substitute parts extend this to -55°C ~ 175°C (TJ), providing wider thermal operating margin and improved reliability in temperature-variable environments.

Q: Can I use IRF1407STRLPBF as a direct drop-in replacement?

A: Yes. The IRF1407STRLPBF matches the 2SK4065-DL-E in 75V Vdss, 100A continuous drain current, and TO-263-3 D2PAK package. Electrical performance is comparable with 7.8mOhm on-resistance versus 6mOhm. Gate charge is slightly higher at 250nC. No circuit modifications are required for mechanical or electrical compatibility.

Q: Which substitute has the lowest input capacitance?

A: The STB100N6F7 has the lowest input capacitance at 1980pF @ 25V, reducing switching losses and improving high-frequency performance. The IRFS3307 variants follow at 4750pF @ 50V. Lower capacitance values reduce driver circuit stress and improve switching speed.
