Both parts maintain Active product status with full RoHS3 compliance
Identical electrical parameters ensure drop-in compatibility
Matching package specifications (6-UDFN Exposed Pad, U-DFN2020-6 Type F) confirm mechanical interchangeability
Both parts carry unlimited moisture sensitivity level (MSL 1), eliminating moisture-related handling constraints
REACH Unaffected status applies to both parts

The DMN2028UFDF-7 is suitable for direct substitution in applications where the DMN2028UFDF-13 is specified, provided that circuit design requirements align with the shared electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can DMN2028UFDF-7 be used as a direct replacement for DMN2028UFDF-13?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, on-state resistance, gate charge, and power dissipation ratings. The package type (6-UDFN Exposed Pad) and mounting configuration are identical, enabling direct substitution in surface mount applications.

Q: What is the difference between the DMN2028UFDF-13 and DMN2028UFDF-7 part numbers?

A: The suffix designation (-13 and -7) indicates different manufacturing batches or distribution channels from Diodes Incorporated. The electrical and mechanical specifications are identical between these variants.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. Both parts use the identical 6-UDFN Exposed Pad package (U-DFN2020-6 Type F) with surface mount configuration. PCB footprints, solder pad layouts, and thermal characteristics are equivalent.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the DMN2028UFDF-13 and DMN2028UFDF-7 are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity level, and maintain REACH Unaffected status. Environmental and regulatory requirements are identical.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution eligibility is determined by matching Vdss (20V), continuous drain current (7.9A @ 25°C), Rds On (25mOhm @ 4A, 4.5V), gate threshold voltage (1V @ 250µA), gate charge (18nC @ 8V), and input capacitance (907pF @ 10V). Both parts meet these specifications identically.
