Engineering Selection Recommendations

Both DMTH46M7SFVW-7 and DMTH46M7SFVWQ-7 are direct electrical and mechanical equivalents to the DMTH46M7SFVWQ-13. Selection between these substitutes is based on product status and compliance requirements:

DMTH46M7SFVWQ-7 is the preferred substitute for applications requiring automotive-grade components. This part maintains Active product status, carries AEC-Q101 qualification, and is available in Tape & Reel packaging format with higher inventory levels (2880 Pcs). The automotive grade designation and AEC-Q101 qualification ensure compliance with automotive industry standards.

DMTH46M7SFVW-7 is an alternative substitute available in Tape & Reel packaging with substantial inventory (2812 Pcs). This part shares all electrical and mechanical specifications with the original part but does not carry automotive grade designation or AEC-Q101 qualification. This part is suitable for non-automotive applications where automotive qualification is not required.

Both substitute parts are ROHS3 compliant and maintain identical electrical performance across all specified parameters. The choice between substitutes depends on application requirements regarding automotive qualification and grade specifications.

Frequently Asked Questions (FAQ)

Q: Are DMTH46M7SFVW-7 and DMTH46M7SFVWQ-7 electrically identical to DMTH46M7SFVWQ-13?

A: Yes. Both substitute parts share identical electrical specifications including Vdss (40V), continuous drain current (16.3A at Ta, 67.2A at Tc), Rds On (7.4mOhm @ 20A, 10V), gate threshold voltage (4V @ 250µA), gate charge (14.8nC @ 10V), input capacitance (1315pF @ 20V), and power dissipation ratings (3.2W at Ta, 54.5W at Tc).

Q: What is the difference between DMTH46M7SFVWQ-13 and its substitutes?

A: The primary differences are product status and packaging format. DMTH46M7SFVWQ-13 is discontinued and supplied in bulk packaging. DMTH46M7SFVWQ-7 and DMTH46M7SFVW-7 are both active products supplied in Tape & Reel format. Additionally, DMTH46M7SFVWQ-7 carries automotive grade designation and AEC-Q101 qualification, while DMTH46M7SFVW-7 does not.

Q: Can DMTH46M7SFVW-7 be used in automotive applications?

A: DMTH46M7SFVW-7 lacks automotive grade designation and AEC-Q101 qualification. For applications requiring automotive-grade components, DMTH46M7SFVWQ-7 is the appropriate substitute.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use the 8-PowerVDFN package with PowerDI3333-8 (SWP) Type UX configuration and wettable flank construction. PCB layouts and footprints are identical across all three parts.

Q: What is the significance of the packaging format difference (bulk versus Tape & Reel)?

A: Packaging format affects handling and assembly processes. Tape & Reel format is standard for automated pick-and-place assembly equipment. Bulk packaging is typically used for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. DMTH46M7SFVWQ-13, DMTH46M7SFVW-7, and DMTH46M7SFVWQ-7 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute part should be selected for new designs?

A: For new designs requiring automotive qualification, DMTH46M7SFVWQ-7 is the appropriate selection. For non-automotive applications, either DMTH46M7SFVW-7 or DMTH46M7SFVWQ-7 can be used based on availability and packaging requirements.
