DMTH4014SPSW-13 Equivalent & Substitute Parts

Part Overview

The DMTH4014SPSW-13 is an N-Channel MOSFET manufactured by Diodes Incorporated, rated for 40V drain-to-source voltage with a continuous drain current of 43.5A at the case temperature (Tc). This device is housed in a PowerDI5060-8 (Type UX) surface mount package with wettable flank construction and is classified as Active product status. The part is ROHS3 compliant and REACH unaffected, making it suitable for industrial and commercial applications requiring high-current switching performance.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits the use of functionally identical components from the same manufacturer's product line.

Engineering Selection Recommendations

DMTH4014SPSW-13 (Primary Part)

The DMTH4014SPSW-13 is the standard industrial-grade variant, suitable for general-purpose switching applications in commercial and industrial environments. Both parts maintain Active product status and are manufactured by Diodes Incorporated with identical electrical and thermal specifications.

DMTH4014SPSWQ-13 (Substitute Part)

The DMTH4014SPSWQ-13 is the automotive-qualified variant of the same MOSFET, carrying AEC-Q101 qualification and Moisture Sensitivity Level (MSL) 1 rating. This part is functionally equivalent to the primary part across all electrical parameters, on-resistance characteristics, gate charge, and thermal performance. The automotive qualification and enhanced moisture sensitivity rating indicate this variant is suitable for automotive and high-reliability applications where stricter qualification standards are required.

Selection Basis:

• Both parts are ROHS3 compliant and REACH unaffected
• Both maintain identical electrical performance and thermal characteristics
• Both are housed in the same 8-PowerTDFN package with PowerDI5060-8 (Type UX) form factor
• The DMTH4014SPSWQ-13 provides additional automotive qualification (AEC-Q101) and improved moisture handling (MSL 1)
• Selection between the two depends on application requirements: standard industrial use favors DMTH4014SPSW-13; automotive or high-reliability applications favor DMTH4014SPSWQ-13
