Key Parameters

Substitute Part Grouping Explanation

Substitution of the DGD21844S14-13 is determined by strict equivalence across the following critical parameters:

• Driven Configuration & Channel Type: Half-bridge, synchronous topology
• Number of Drivers: Dual-channel configuration
• Gate Type Compatibility: IGBT and N-Channel MOSFET support
• Supply Voltage Range: 10V to 20V operation
• Logic Voltage Thresholds: VIL = 0.8V, VIH = 2.5V
• Peak Output Current: Source 1.4A, Sink 1.8A
• Input Signal Type: Non-inverting
• Bootstrap Voltage Rating: 600V maximum
• Timing Characteristics: Rise time 40ns, fall time 20ns
• Package Specification: 14-SOIC form factor
• Regulatory Compliance: ROHS3 compliance required

The DGD21844MS14-13 meets all these criteria and qualifies as a direct substitute. Packaging differences (tape & reel versus bulk) and product status variations do not affect functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The DGD21844MS14-13 is a direct functional equivalent to the DGD21844S14-13. Both devices share identical electrical specifications, gate drive characteristics, and package form factors. The primary distinction is product status: the original part is classified as Obsolete, while the substitute carries Active status, ensuring continued availability and manufacturing support.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production environments. The DGD21844MS14-13 is supplied in tape & reel packaging, which is standard for automated assembly processes. Selection between these parts should be based on procurement availability, supply chain requirements, and packaging format compatibility with manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can the DGD21844MS14-13 replace the DGD21844S14-13 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The DGD21844MS14-13 operates within the same supply voltage range (10V–20V), delivers identical peak output currents (1.4A source, 1.8A sink), and maintains the same logic voltage thresholds and timing characteristics. No circuit modifications are required.

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

A: The primary difference is product status and packaging format. The DGD21844S14-13 is Obsolete, while the DGD21844MS14-13 is Active. The substitute is supplied in tape & reel format, standard for high-volume manufacturing, whereas the original may have been available in alternative packaging. Both parts are manufactured by Diodes Incorporated and share the same base product number (DGD21844).

Q: Are there any thermal or reliability differences between these parts?

A: The DGD21844S14-13 specifies an operating temperature range of -40°C to 150°C (TJ). The DGD21844MS14-13 specifies a maximum junction temperature of 150°C. Both parts are rated for the same maximum temperature. Moisture sensitivity differs: the original part carries MSL 3 (168 hours), while the substitute carries MSL 1 (unlimited). This indicates improved moisture resistance in the substitute part.

Q: Is the 14-SOIC package identical for both parts?

A: Yes. Both parts use the 14-SOIC package with 0.154" (3.90mm) width. Pin configuration, lead spacing, and PCB footprint are identical. No layout modifications are necessary when substituting one part for the other.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DGD21844S14-13 and DGD21844MS14-13 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. They satisfy identical regulatory requirements for commercial and industrial applications.
