DMC3026LSD-13 Equivalent & Substitute Parts

Part Overview

The DMC3026LSD-13 is an N and P-Channel complementary MOSFET array manufactured by Diodes Incorporated, rated for 30V drain-to-source voltage with continuous drain current ratings of 8.2A and 8A at 25°C. This device is packaged in an 8-SOIC surface mount configuration and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with 2338 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, experiences supply constraints, or when design flexibility requires alternative qualified sources. The FDS8958B from onsemi represents a functionally compatible alternative, though it carries a Last Time Buy status and exhibits different electrical performance characteristics that must be evaluated against application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the DMC3026LSD-13 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-source voltage rating (Vdss) must equal or exceed 30V
• Continuous drain current (Id) must support the application's maximum current demand
• Gate threshold voltage (Vgs(th)) must remain within 3V specification
• On-state resistance (Rds On) affects power dissipation and thermal performance
• Power dissipation rating must accommodate circuit operating conditions

Mechanical Compatibility Criteria:

• Package type must be 8-SOIC with identical pin configuration
• Surface mount mounting type required
• Physical dimensions (0.154", 3.90mm width) must match PCB layout

Functional Compatibility Criteria:

• Configuration must maintain N and P-Channel complementary topology
• Operating temperature range must span -55°C to 150°C minimum
• Technology platform must be MOSFET (Metal Oxide)

The FDS8958B from onsemi meets the core electrical and mechanical requirements for substitution. However, the substitute exhibits reduced continuous drain current (6.4A and 4.5A versus 8.2A and 8A) and lower maximum power dissipation (900mW versus 1.6W), which may limit its application in high-current or high-power scenarios.

Engineering Selection Recommendations

DMC3026LSD-13 Selection Criteria: The DMC3026LSD-13 is the primary choice for new designs and applications requiring maximum current handling capacity. Active production status ensures long-term availability and supply chain stability. AEC-Q101 automotive qualification provides validated performance for automotive and industrial applications. The higher continuous drain current (8.2A/8A) and power dissipation rating (1.6W) support demanding circuit topologies with minimal thermal constraints.

FDS8958B Selection Criteria: The FDS8958B is suitable for applications where continuous drain current requirements do not exceed 6.4A and 4.5A ratings. The Last Time Buy status indicates this part is approaching end-of-life; procurement must account for limited future availability. The reduced power dissipation rating (900mW) restricts use in high-power applications. Selection of this substitute requires verification that application current and thermal requirements remain within specified limits.

Compliance Considerations: Both parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status. Automotive applications utilizing the DMC3026LSD-13 benefit from AEC-Q101 qualification; the FDS8958B does not carry this certification and requires independent qualification assessment for automotive use.

Frequently Asked Questions (FAQ)

Q: Can the FDS8958B directly replace the DMC3026LSD-13 in all applications?

A: Direct replacement is limited by electrical performance differences. The FDS8958B supports lower continuous drain current (6.4A/4.5A versus 8.2A/8A) and reduced power dissipation (900mW versus 1.6W). Applications operating at or near the DMC3026LSD-13's maximum current ratings cannot use the FDS8958B without circuit redesign or thermal management modifications.

Q: Are the packages physically identical?

A: Both parts use 8-SOIC packaging with identical physical dimensions (0.154", 3.90mm width). Pin-to-pin compatibility exists for direct PCB layout substitution without layout modifications.

Q: What is the significance of the FDS8958B's Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has announced end-of-life production. Existing inventory may be available, but future procurement will not be possible. Long-term designs should prioritize the active-status DMC3026LSD-13 to avoid supply discontinuation.

Q: Are both parts suitable for automotive applications?

A: The DMC3026LSD-13 carries AEC-Q101 automotive qualification, meeting automotive industry reliability and performance standards. The FDS8958B does not carry this certification. Automotive applications must use the DMC3026LSD-13 or conduct independent AEC-Q101 qualification of the FDS8958B.

Q: How do the on-state resistance values compare?

A: The DMC3026LSD-13 specifies 25mOhm and 28mOhm at 6A, 10V. The FDS8958B specifies 26mOhm at 6.4A, 10V. Resistance values are comparable at equivalent operating points, resulting in similar power dissipation characteristics at matched current levels.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, carry MSL Level 1 (unlimited moisture sensitivity), and maintain REACH unaffected status. These certifications ensure environmental compliance and handling flexibility for manufacturing and storage.
