• Gate Drive Voltage: Must support 10V operation
• On-State Resistance (Rds On): Must not significantly exceed 270mOhm @ 8A, 10V to maintain thermal performance
• Gate Threshold Voltage (Vgs(th)): Must be compatible with 4V @ 250µA
• Maximum Gate Voltage (Vgs): Must support ±30V
• Power Dissipation: Must support minimum 160W (Tc) thermal requirements
• Operating Temperature: Must span -55°C to 150°C (TJ)

Mechanical Compatibility Criteria:

• Package Type: TO-252-3, DPAK (2 Leads + Tab), SC-63
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Regulatory Compliance:

• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 8541.29.0095

Substitute parts are classified into two categories: Parametric Equivalents (identical electrical specifications) and Similar Parts (compatible but with parameter variations within acceptable operational limits).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent - FQD16N25CTM:

The FQD16N25CTM is a direct parametric equivalent to the FQD16N25CTM_F080. Both devices share identical electrical specifications across all critical parameters: 250V Vdss, 16A continuous drain current, 270mOhm Rds On, and 160W power dissipation. The primary distinction is product status: FQD16N25CTM is Active, whereas FQD16N25CTM_F080 is Obsolete. The FQD16N25CTM is supplied in Tape & Reel (TR) packaging and carries ROHS3 Compliant certification. This part is the preferred direct replacement for the obsolete variant.

Similar Part - AOD458:

The AOD458 from Alpha & Omega Semiconductor Inc. is compatible for applications where continuous drain current requirements do not exceed 14A. This device maintains the same 250V Vdss rating and 10V drive voltage. The Rds On specification is marginally higher at 280mOhm @ 7A, 10V compared to 270mOhm @ 8A, 10V for the main part. Power dissipation is rated at 150W (Tc), which is 10W lower than the FQD16N25CTM_F080. The AOD458 operates across -50°C to 175°C (TJ), providing extended high-temperature capability. This part is suitable for designs with reduced current demands or where the extended temperature range provides operational advantage.

Similar Part - RCD080N25TL:

The RCD080N25TL from Rohm Semiconductor is compatible for applications requiring reduced continuous drain current of 8A or less. This device maintains 250V Vdss and 10V drive voltage compatibility. The Rds On specification is 300mOhm @ 4A, 10V. Power dissipation is significantly lower at 850mW (Ta) and 20W (Tc), indicating this device is suitable for lower-power switching applications. The RCD080N25TL is supplied in CPT3 package format. This part is applicable only to designs with current requirements not exceeding 8A.

Regulatory and Compliance Status:

All substitute parts maintain REACH Unaffected status, EAR99 ECCN classification, and HTSUS 8541.29.0095 coding, ensuring regulatory consistency with the original part. The FQD16N25CTM and AOD458 carry ROHS3 Compliant certification, supporting modern environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can FQD16N25CTM be used as a direct replacement for FQD16N25CTM_F080?

A: Yes. The FQD16N25CTM is a parametric equivalent with identical electrical specifications. Both devices feature 250V Vdss, 16A continuous drain current, 270mOhm Rds On @ 8A, 10V, and 160W power dissipation. The primary difference is that FQD16N25CTM is Active status while FQD16N25CTM_F080 is Obsolete. Mechanical compatibility is maintained through identical TO-252AA packaging.

Q: What are the current limitations when using AOD458 as a substitute?

A: The AOD458 is rated for 14A continuous drain current compared to 16A for the FQD16N25CTM_F080. Applications requiring sustained currents above 14A are not suitable for this substitute. Additionally, power dissipation is rated at 150W (Tc) versus 160W (Tc) for the main part, requiring thermal design verification for high-power applications.

Q: Is RCD080N25TL suitable for all applications using FQD16N25CTM_F080?

A: No. The RCD080N25TL is rated for only 8A continuous drain current and 20W (Tc) power dissipation, making it suitable only for applications with significantly reduced current and power requirements. This part is not a general-purpose substitute but rather a lower-power alternative for specific design scenarios.

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

A: FQD16N25CTM and AOD458 both use TO-252-3 DPAK packaging and are footprint-compatible with FQD16N25CTM_F080. The RCD080N25TL uses CPT3 package format, which differs from the DPAK standard and requires PCB layout verification before substitution.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous tape reels suitable for automated assembly processes. Cut Tape (CT) & Digi-Reel® packaging is supplied in shorter tape segments. Both formats contain identical components; the difference is in supply format and handling for manufacturing operations.

Q: Do all substitute parts meet the same temperature operating range?

A: No. FQD16N25CTM operates -55°C to 150°C (TJ), matching the original part. AOD458 extends to -50°C to 175°C (TJ), providing wider high-temperature capability. RCD080N25TL is specified at 150°C (TJ) maximum. Design thermal requirements must be verified against each substitute's operating range.

Q: Are there differences in gate charge characteristics between the main part and substitutes?

A: Yes. FQD16N25CTM matches the main part at 53.5 nC @ 10V. AOD458 has significantly lower gate charge at 15 nC @ 10V, resulting in faster switching characteristics. RCD080N25TL has 25 nC @ 10V. Gate drive circuit design may require adjustment based on these differences.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. All listed parts and substitutes carry this rating, ensuring consistent handling requirements.

Q: Are all substitute parts ROHS3 compliant?

A: FQD16N25CTM and AOD458 are explicitly ROHS3 Compliant. RoHS status for RCD080N25TL is also ROHS3 Compliant. The original FQD16N25CTM_F080 does not specify RoHS status. All active substitutes meet modern environmental compliance standards.
