Key Parameters

Substitute Part Grouping Explanation

The DGD0590AFU-7 qualifies as a direct substitute for the DGD0590FU-7 based on the following critical parameters:

Electrical Compatibility:

• Identical driven configuration (half-bridge)
• Identical number of drivers (2)
• Identical gate type (N-channel MOSFET)
• Identical supply voltage range (4.5V ~ 5.5V)
• Identical peak output currents (1A source, 3A sink)
• Identical input type (non-inverting)
• Identical bootstrap voltage rating (50V maximum)
• Identical rise/fall times (27ns, 29ns typical)

Mechanical Compatibility:

• Identical package type (8-VQFN Exposed Pad)
• Identical supplier device package (V-QFN3030-8 Type TH)

Regulatory Compliance:

• Identical RoHS3 compliance status
• Identical REACH status (unaffected)
• Identical ECCN and HTSUS classifications

The primary distinction is product status: DGD0590AFU-7 is active with high inventory availability, whereas DGD0590FU-7 is obsolete. The DGD0590AFU-7 is supplied in Tape & Reel packaging with MSL 3 (168 hours) versus the original part's MSL 1 (unlimited).

Parameter Comparison

Engineering Selection Recommendations

The DGD0590AFU-7 is the direct active equivalent for the obsolete DGD0590FU-7. Selection of the substitute part is based on:

Product Status: The DGD0590AFU-7 maintains active production status with substantial inventory availability (10,518 pcs), ensuring long-term supply chain reliability compared to the obsolete original part.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying equivalent environmental and regulatory requirements.

Electrical and Mechanical Specifications: All functional parameters, electrical ratings, and package specifications are identical, enabling direct pin-for-pin and functional replacement without circuit modification.

Packaging Consideration: The substitute part is supplied in standard Tape & Reel format, which is the industry standard for automated assembly processes. The MSL 3 rating (168 hours) requires standard moisture control during storage and handling, consistent with modern manufacturing practices.

Frequently Asked Questions (FAQ)

Q: Can DGD0590AFU-7 be used as a direct replacement for DGD0590FU-7?

A: Yes. The DGD0590AFU-7 is electrically and mechanically identical to the DGD0590FU-7. All electrical parameters, pin configurations, and functional specifications match exactly. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. DGD0590FU-7 is obsolete; DGD0590AFU-7 is active production. DGD0590AFU-7 is supplied in Tape & Reel packaging with MSL 3 (168 hours) moisture sensitivity, while DGD0590FU-7 was supplied in bulk with MSL 1 (unlimited).

Q: Are there any compatibility concerns with the MSL 3 rating?

A: No. MSL 3 (168 hours) is standard for modern surface-mount components. This rating indicates the component can be exposed to 85°C / 85% relative humidity for up to 168 hours before soldering. Standard moisture control procedures during storage and handling ensure full compatibility.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Yes. Tape & Reel is the standard packaging format for automated pick-and-place assembly equipment. If manual assembly is required, the component can be removed from the tape for individual handling.

Q: Do both parts have identical electrical performance?

A: Yes. Rise/fall times, output current ratings, supply voltage range, bootstrap voltage rating, and all other electrical specifications are identical between DGD0590FU-7 and DGD0590AFU-7.

Q: What is the operating temperature range for the substitute part?

A: The DGD0590AFU-7 operates across -40°C to 150°C junction temperature, identical to the original part.
