Engineering Selection Recommendations

DMN2022UFDF-7 (Parametric Equivalent): This part is manufactured by Diodes Incorporated and maintains identical electrical specifications to the DMN2022UFDF-13 across all critical parameters. Both devices share the same base product number (DMN2022) and are housed in the 6-UDFN Exposed Pad package. The DMN2022UFDF-7 is ROHS3 compliant with MSL 1 (Unlimited) rating. This substitute is suitable for direct replacement in applications where the primary part is unavailable. Current inventory for DMN2022UFDF-7 is 1817 pieces.

FDMA410NZT (Manufacturer Recommended): This onsemi device exceeds the electrical performance of the DMN2022UFDF-13 with a continuous drain current rating of 9.5A compared to 7.9A, and increased power dissipation capability of 2.4W versus 660mW. The FDMA410NZT maintains the same 20V Vdss rating, equivalent gate threshold voltage, and identical operating temperature range. The device is packaged in 6-UDFN (2.05x2.05) with exposed pad, maintaining mechanical compatibility. ROHS3 compliance and MSL 1 (Unlimited) rating are confirmed. The lower gate charge (14 nC @ 4.5V) provides improved switching characteristics. Current inventory for FDMA410NZT is 3316 pieces. This substitute is applicable in designs requiring enhanced current handling or thermal performance within the same voltage class.

All substitute parts maintain Active product status and are compliant with REACH and EAR99 export classifications.

Frequently Asked Questions (FAQ)

Q: Can DMN2022UFDF-7 be used as a direct replacement for DMN2022UFDF-13?

A: Yes. The DMN2022UFDF-7 is a parametric equivalent with identical electrical specifications including Vdss (20V), Id (7.9A), Rds On (22 mOhm @ 4A, 4.5V), and operating temperature range (-55°C to 150°C). Both parts use the same 6-UDFN Exposed Pad package and are manufactured by Diodes Incorporated. The parts are electrically and mechanically interchangeable.

Q: What are the advantages of using FDMA410NZT over DMN2022UFDF-13?

A: The FDMA410NZT provides higher continuous drain current (9.5A versus 7.9A) and significantly increased power dissipation capability (2.4W versus 660mW). Gate charge is reduced to 14 nC @ 4.5V, enabling faster switching response. These characteristics make the FDMA410NZT suitable for applications requiring enhanced thermal performance or higher current capacity within the 20V voltage rating.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All listed substitute parts utilize the 6-UDFN Exposed Pad package format. The FDMA410NZT is specified as 6-UDFN (2.05x2.05), which maintains footprint compatibility with the standard 6-UDFN package used by the DMN2022UFDF-13 and DMN2022UFDF-7.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts listed are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. All parts are classified under EAR99 export control.

Q: What is the difference between the DMN2022UFDF-13 and DMN2022UFDF-7 part numbers?

A: The suffix difference (-13 versus -7) indicates different manufacturing date codes or tape reel configurations. The electrical and mechanical specifications are identical. Both parts share the base product number DMN2022 and are functionally equivalent.

Q: Can FDMA410NZT be used in applications designed for 7.9A continuous current?

A: Yes. The FDMA410NZT is rated for 9.5A continuous drain current, which exceeds the 7.9A requirement. The device maintains equivalent gate threshold voltage (1V @ 250µA), operating temperature range, and voltage rating. The higher current rating provides design margin without compromising compatibility.

Q: What packaging format is used for these MOSFETs?

A: All parts are surface mount devices in 6-UDFN (Micro Flat No-Lead) packages with exposed pad. The DMN2022UFDF-13 and DMN2022UFDF-7 use U-DFN2020-6 (Type F) designation. The FDMA410NZT uses 6-UDFN (2.05x2.05) designation. Both formats are mechanically compatible for PCB assembly.
