Engineering Selection Recommendations

DMN3028LQ-7 as Primary Substitute:

The DMN3028LQ-7 is a direct parametric equivalent to the DMN3028L-13. Both devices share identical electrical specifications, thermal ratings, and mechanical packaging. The primary distinction is packaging format: the DMN3028L-13 is supplied in Tape & Reel (TR) format, while the DMN3028LQ-7 is available in Cut Tape (CT) and Digi-Reel® format.

Both parts maintain active production status and comply with ROHS3 and REACH regulatory requirements. The DMN3028LQ-7 carries AEC-Q101 automotive qualification and Moisture Sensitivity Level (MSL) 1 rating, indicating suitability for automotive and high-reliability applications.

Selection between these parts should be based on procurement requirements, supply chain availability, and packaging format compatibility with assembly processes. The DMN3028LQ-7 offers significantly higher inventory availability (52,991 pieces) compared to the DMN3028L-13 (943 pieces).

Frequently Asked Questions (FAQ)

Q: Can the DMN3028LQ-7 replace the DMN3028L-13 in existing circuit designs?

A: Yes. The DMN3028LQ-7 is a parametric equivalent with identical electrical characteristics, thermal performance, and mechanical packaging. Direct substitution is supported without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® packaging provide components in smaller quantities on cut tape segments, suitable for lower-volume production or manual assembly. Electrical and mechanical specifications remain identical.

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

A: No. Both the DMN3028L-13 and DMN3028LQ-7 share identical drain-to-source voltage, continuous drain current, on-state resistance, gate charge, input capacitance, power dissipation, and operating temperature specifications.

Q: Does the DMN3028LQ-7 automotive qualification affect general-purpose applications?

A: No. AEC-Q101 qualification indicates the part meets automotive reliability standards and is suitable for automotive applications. This qualification does not restrict use in general-purpose or industrial applications.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture absorption concerns. Components with MSL 1 do not require special moisture-control storage or handling procedures prior to assembly.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DMN3028L-13 and DMN3028LQ-7 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for European and global markets.
