Equivalent & Substitute Parts Reference for DMN4027SSDQ-13

Part Overview

The DMN4027SSDQ-13 by Diodes Incorporated is an automotive-grade, dual N-channel 40V MOSFET array, packaged in an 8-SOP surface-mount format. Key electrical and mechanical parameters include a continuous drain current of 5.4A at 25°C, maximum Rds(on) of 27mOhm at 7A/10V, and a package specification of 8-SOIC with 3.90mm width. The part is active, ROHS3 compliant, and AEC-Q101 qualified. Substitution may be necessary due to inventory needs, product availability, or design requirements. Equivalent models must match critical voltage, current, configuration, and mechanical packaging parameters.

Substitute Part Grouping Explanation

Substitute and equivalent parts for the DMN4027SSDQ-13 are grouped based on strict matching of the following parameters: category, MOSFET technology, dual N-channel configuration, drain-source voltage rating (40V), continuous drain current, Rds(on) maximum value under specified test conditions, threshold voltage, gate charge, input capacitance, power dissipation, operating temperature range, and mechanical package (8-SOIC, surface mount). Compliance and quality criteria, such as ROHS3 and AEC-Q101, are addressed where applicable.

Parameter Comparison

Engineering Selection Recommendations

AO4840 by Alpha & Omega Semiconductor Inc. is not for new designs. FDS8949 by onsemi is active. Both substitutes are ROHS3 compliant and REACH unaffected. DMN4027SSDQ-13 is automotive grade and AEC-Q101 qualified; confirm qualification needs if substituting with non-automotive alternatives. Selection based solely on product status and regulatory compliance as provided.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting DMN4027SSDQ-13 with AO4840 or FDS8949?

A1: Substitutes are selected by matching category, MOSFET technology, dual N-channel configuration, voltage/current ratings, Rds(on) specification, packaging, and regulatory status.

Q2: Are all substitute parts available in the same package type as DMN4027SSDQ-13?

A2: All listed substitutes use an 8-SOIC (0.154", 3.90mm width) surface mount package.

Q3: Does the difference in power rating or input capacitance affect substitution eligibility?

A3: Selection is strictly governed by the provided input parameters. Both substitutes meet the required mechanical and primary electrical criteria.

Q4: Should automotive grade and AEC-Q101 qualification be considered for all substitutes?

A4: DMN4027SSDQ-13 is automotive grade and AEC-Q101 qualified. Substitute selection must be made in accordance with necessary qualification requirements if mandated by the application.

Q5: Are all substitutes compliant with ROHS3 and REACH?

A5: Listed substitutes are ROHS3 compliant and REACH unaffected, according to the provided data.

Q6: Why is product status important in selecting substitutes?

A6: Active status confirms ongoing manufacture and support; a “not for new designs” status indicates limited future supply or support. Select substitutes with active product status for long-term designs.
