Engineering Selection Recommendations

DMN6066SSS-13 as Direct Substitute:

The DMN6066SSS-13 is a parametric equivalent to the DMN6066SSSQ-13. Both devices share identical electrical specifications, thermal characteristics, and package geometry. The primary distinction is the packaging format: the DMN6066SSSQ-13 is supplied in Tape & Reel (TR) format with automotive-grade qualification (AEC-Q101), while the DMN6066SSS-13 is supplied in standard Tape & Reel format without explicit automotive qualification designation in the part number suffix.

Both parts maintain:

Active production status
RoHS3 compliance
Unlimited moisture sensitivity level (MSL 1)
REACH unaffected status
Identical electrical performance across all rated parameters

Selection between these parts depends on supply chain requirements, packaging format availability, and whether automotive qualification documentation is mandated by the application. The electrical and thermal performance are functionally identical, permitting direct substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the DMN6066SSS-13 replace the DMN6066SSSQ-13 in automotive applications?

A: The DMN6066SSS-13 possesses identical electrical and thermal specifications. However, the DMN6066SSSQ-13 carries explicit AEC-Q101 automotive qualification in its part number designation. If automotive qualification documentation is a contractual or regulatory requirement, the DMN6066SSSQ-13 is the specified part. If qualification documentation can be obtained separately or is not required, the DMN6066SSS-13 provides equivalent electrical performance.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the DMN6066SSSQ-13 and DMN6066SSS-13 use the 8-SOIC package with 0.154" (3.90mm) width. PCB footprints and thermal characteristics are identical.

Q: What is the difference between the "Q" suffix in DMN6066SSSQ-13?

A: The "Q" suffix indicates AEC-Q101 automotive qualification. The DMN6066SSS-13 lacks this designation in the part number, though both devices meet identical electrical specifications and operating temperature ranges.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) with identical power dissipation ratings of 1.56W. Thermal performance is equivalent.

Q: Are there any differences in gate charge or switching characteristics?

A: No. Gate charge (Qg) is specified at 10.3 nC @ 10V for both parts. Input capacitance (Ciss) is 502 pF @ 30V for both. All switching and capacitive parameters are identical.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DMN6066SSSQ-13 and DMN6066SSS-13 are ROHS3 compliant and REACH unaffected.
