Key Parameters

Substitute Part Grouping Explanation

Substitution of the DGD21042S8-13 is determined by strict equivalence across the following critical parameters:

• Driven configuration (half-bridge topology)
• Channel type (synchronous operation)
• Number of drivers (2 channels)
• Gate type compatibility (IGBT and N-Channel MOSFET support)
• Supply voltage range (10V ~ 20V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.5V)
• Peak output current specifications (source 290mA, sink 600mA)
• Input logic type (non-inverting)
• Bootstrap voltage rating (600V maximum)
• Timing characteristics (rise/fall times 70ns/35ns typical)
• Operating temperature range (-40°C ~ 150°C)
• Package form factor (8-SOIC)
• Surface mount compatibility

The DGD2104MS8-13 meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The DGD2104MS8-13 is the direct substitute for the obsolete DGD21042S8-13. Both parts are manufactured by Diodes Incorporated and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product status: the DGD21042S8-13 is obsolete, while the DGD2104MS8-13 is active and currently in production. The DGD2104MS8-13 is supplied in Tape & Reel packaging format, which is standard for production environments, whereas the original part was available in bulk packaging.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The identical operating temperature range, supply voltage specifications, output current ratings, and timing characteristics confirm functional equivalence for all half-bridge gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can the DGD2104MS8-13 be used as a direct replacement for the DGD21042S8-13?

A: Yes. The DGD2104MS8-13 is electrically and mechanically equivalent to the DGD21042S8-13. All functional parameters, including supply voltage, output current, timing characteristics, and operating temperature range, are identical. The parts are pin-compatible and functionally interchangeable.

Q: What is the difference between the DGD21042S8-13 and DGD2104MS8-13?

A: The primary differences are product status and packaging format. The DGD21042S8-13 is obsolete and was supplied in bulk packaging. The DGD2104MS8-13 is an active product supplied in Tape & Reel format. All electrical specifications and package form factors are identical.

Q: Are there any compatibility concerns when switching from DGD21042S8-13 to DGD2104MS8-13?

A: No compatibility concerns exist. Both parts use the same 8-SOIC package footprint and pin configuration. PCB layouts, schematic designs, and application circuits require no modification.

Q: Does the packaging format change affect circuit performance?

A: No. Packaging format (bulk versus Tape & Reel) affects only handling and assembly processes. It does not impact electrical performance, reliability, or functional characteristics of the gate driver IC.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the DGD21042S8-13 and DGD2104MS8-13 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
