Substitute Part Grouping Explanation

Substitution eligibility for the DGD0547FN-7 is determined by the following critical parameters:

• Driven Configuration: Must be Half-Bridge
• Number of Drivers: Must be 2
• Gate Type: Must be N-Channel MOSFET
• Voltage - Supply Range: Must support 0.3V ~ 60V
• Package / Case: Must be 10-WFDFN Exposed Pad
• Input Type: Must be CMOS/TTL compatible
• High Side Voltage - Max (Bootstrap): Must support minimum 50V

The DGD05473FN-7 meets all substitution criteria. Both components share identical supply voltage ranges, package specifications, input logic compatibility, and bootstrap voltage ratings. The substitute part maintains functional equivalence for half-bridge gate driving applications.

Parameter Comparison

Engineering Selection Recommendations

The DGD05473FN-7 is the direct substitute for the obsolete DGD0547FN-7. Both components are manufactured by Diodes Incorporated and maintain identical electrical specifications across all critical parameters including supply voltage range, package form factor, logic thresholds, and thermal operating range.

The DGD05473FN-7 offers the advantage of active product status, ensuring continued availability and manufacturing support. The substitute part carries equivalent ROHS3 compliance and REACH unaffected status, meeting the same regulatory requirements as the original component.

The peak output sink current specification of the DGD05473FN-7 is rated at 2.5A compared to 2A for the DGD0547FN-7, providing enhanced current delivery capability while maintaining full backward compatibility in half-bridge gate driving applications.

Frequently Asked Questions (FAQ)

Q: Can the DGD05473FN-7 directly replace the DGD0547FN-7 in existing designs?

A: Yes. Both components share identical package specifications (10-WFDFN Exposed Pad), supply voltage ranges (0.3V ~ 60V), logic input thresholds, and bootstrap voltage ratings. No circuit modifications are required for substitution.

Q: What is the difference between Synchronous and Independent channel types?

A: Channel type describes the control architecture of the gate drivers. The DGD0547FN-7 uses synchronous control, while the DGD05473FN-7 uses independent control. Both configurations support half-bridge topologies and maintain functional equivalence for standard gate driving applications.

Q: Does the higher sink current rating of the DGD05473FN-7 affect compatibility?

A: No. The increased peak output sink current (2.5A versus 2A) represents an enhancement that maintains full backward compatibility. Designs operating within the original 2A specification will function identically with the substitute part.

Q: Are there any compliance or certification differences between these parts?

A: Both components carry identical ROHS3 compliance and REACH unaffected status. Moisture sensitivity levels are equivalent at MSL 3 (168 Hours). No compliance-related restrictions apply to substitution.

Q: Why is the DGD0547FN-7 classified as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Diodes Incorporated. The DGD05473FN-7 represents the active continuation of this product line with maintained electrical and mechanical compatibility.
