Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMC3035LSD-13 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain to Source Voltage (Vdss): 30V minimum
• Dual N-channel and P-channel configuration
• Logic-level gate operation
• Surface-mount 8-SOIC package (0.154", 3.90mm Width)
• Operating temperature range: -55°C to 150°C
• Maximum power dissipation: 2W
• RoHS3 compliance

Current Rating Tolerance: Substitute parts must maintain continuous drain current ratings within the operational envelope of the original specification. The DMC3035LSD-13 specifies 6.9A (N-channel) and 5A (P-channel). Substitute parts with equivalent or superior current ratings are acceptable provided all other parameters remain within specification.

On-Resistance Consideration: The Rds On specification of 35mOhm at 6.9A, 10V establishes the thermal and switching performance baseline. Substitute parts with equal or lower on-resistance values maintain or improve performance characteristics.

Two substitute parts meet these criteria and are identified as direct equivalents.

Engineering Selection Recommendations

IRF9389TRPBF (Infineon Technologies)

The IRF9389TRPBF is an active-status substitute manufactured by Infineon Technologies under the HEXFET® series designation. This part maintains full electrical compatibility with the DMC3035LSD-13 across all critical parameters: 30V Vdss rating, dual N/P-channel configuration, 8-SOIC package geometry, and -55°C to 150°C operating range. The IRF9389TRPBF demonstrates improved on-resistance performance (27mOhm versus 35mOhm), resulting in lower thermal dissipation. Current ratings of 6.8A (N-channel) and 4.6A (P-channel) remain within the operational envelope of the original specification. ROHS3 compliance and unlimited moisture sensitivity rating ensure regulatory and environmental compatibility. Active product status ensures long-term availability and supply chain continuity.

SP8M10FRATB (Rohm Semiconductor)

The SP8M10FRATB is an active-status substitute manufactured by Rohm Semiconductor with automotive-grade qualification (AEC-Q101). This part satisfies all critical substitution parameters: 30V Vdss, N/P-channel configuration, 8-SOIC package, and -55°C to 150°C operating range. The SP8M10FRATB provides superior on-resistance performance (25mOhm at 7A, 10V) and higher N-channel current rating (7A versus 6.9A). ROHS3 compliance and unlimited moisture sensitivity rating are maintained. Automotive qualification provides additional reliability assurance for applications requiring enhanced environmental and operational stress testing. Active product status ensures sustained component availability.

Both substitutes are electrically and mechanically compatible with the obsolete DMC3035LSD-13 and are suitable for direct replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the IRF9389TRPBF and SP8M10FRATB be used interchangeably with the DMC3035LSD-13?

A: Yes. Both substitute parts meet all critical electrical and mechanical parameters required for direct replacement: 30V Vdss rating, N and P-channel configuration, logic-level gate operation, 8-SOIC package geometry, and -55°C to 150°C operating temperature range. Pin-to-pin compatibility is maintained across all three parts.

Q: What are the key differences between the two substitute options?

A: The IRF9389TRPBF (Infineon) offers 27mOhm on-resistance and is designated as a general-purpose MOSFET array. The SP8M10FRATB (Rohm) provides 25mOhm on-resistance and carries automotive-grade qualification (AEC-Q101), making it suitable for applications requiring enhanced reliability testing and environmental stress screening. Both parts are active products with established supply chains.

Q: Are there any current rating differences that affect circuit performance?

A: The DMC3035LSD-13 specifies 6.9A (N-channel) and 5A (P-channel). The IRF9389TRPBF provides 6.8A and 4.6A respectively, while the SP8M10FRATB provides 7A and 4.5A. All three parts operate within compatible current envelopes for typical dual-channel switching applications. Thermal analysis should be performed for applications operating at maximum continuous current.

Q: Is the 8-SOIC package identical across all three parts?

A: Yes. All three parts use the 8-SOIC package with 0.154" (3.90mm) width specification. PCB footprints and reflow soldering profiles are compatible without modification.

Q: What is the significance of the SP8M10FRATB automotive qualification?

A: The AEC-Q101 qualification indicates that the SP8M10FRATB has undergone automotive-grade reliability testing, including thermal cycling, humidity resistance, and electrostatic discharge protection. This qualification is required for automotive and industrial applications with enhanced reliability requirements but is not necessary for general commercial applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DMC3035LSD-13, IRF9389TRPBF, and SP8M10FRATB are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with lead-free soldering processes and environmental regulations.

Q: Which substitute part should be selected for new designs?

A: Selection between the IRF9389TRPBF and SP8M10FRATB depends on application requirements. For general commercial applications, either part is suitable. For automotive or industrial applications requiring enhanced reliability documentation, the SP8M10FRATB is the appropriate choice. Both parts are active products with established supply availability.
