Engineering Selection Recommendations

Primary Substitute: SRAF1090HC0G

The SRAF1090HC0G is the optimal substitute for the discontinued MBRF1090HC0G. Both parts maintain identical electrical specifications, mechanical packaging, and automotive-grade certifications. The SRAF1090HC0G carries active product status with 844 units in stock, ensuring supply continuity. Both parts are AEC-Q101 qualified and designated as automotive-grade components, making this substitution suitable for applications requiring automotive compliance.

Secondary Substitutes: MBRF1090H and MBRF1090C0G

The MBRF1090H and MBRF1090C0G are parametrically equivalent alternatives with active product status. These parts match all electrical and mechanical specifications of the main part. However, automotive-grade designation and AEC-Q101 qualification are not specified for these variants. Selection of these alternatives is appropriate for non-automotive applications or where automotive qualification is not a circuit requirement.

Tertiary Substitute: SRAF1090C0G

The SRAF1090C0G provides parametric equivalence with active availability. This part does not carry specified automotive-grade designation or AEC-Q101 qualification. Use this substitute only in applications where automotive compliance is not mandated.

All substitute parts are manufactured by Taiwan Semiconductor Corporation and are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can MBRF1090H be used as a direct replacement for MBRF1090HC0G?

A: The MBRF1090H is electrically and mechanically equivalent to the MBRF1090HC0G across all specified parameters. However, automotive-grade designation and AEC-Q101 qualification are not specified for the MBRF1090H. Use this substitute only if your application does not require automotive compliance.

Q: What is the difference between MBRF1090HC0G and SRAF1090HC0G?

A: Both parts are identical in electrical performance, mechanical packaging, and automotive certifications. The primary difference is the base product number designation (MBRF versus SRAF). Both are manufactured by Taiwan Semiconductor Corporation and are suitable for automotive applications requiring AEC-Q101 qualification.

Q: Are all substitute parts compatible with the original TO-220-2 package footprint?

A: Yes. All substitute parts use the TO-220-2 Full Pack configuration with identical through-hole mounting specifications. Direct PCB footprint compatibility is maintained across all listed alternatives.

Q: Which substitute should be selected for automotive applications?

A: For automotive applications, select either SRAF1090HC0G or MBRF1090HC0G. Both parts carry automotive-grade designation and AEC-Q101 qualification. The SRAF1090HC0G is recommended due to active product status and current availability.

Q: Do all substitute parts meet ROHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What is the current inventory status of available substitutes?

A: MBRF1090H: 865 units in stock. MBRF1090C0G: 853 units in stock. SRAF1090C0G: 829 units in stock. SRAF1090HC0G: 844 units in stock. All substitutes are available as new original stock.

Q: Can SRAF1090C0G replace MBRF1090HC0G in automotive circuits?

A: The SRAF1090C0G is electrically and mechanically equivalent but does not carry specified automotive-grade designation or AEC-Q101 qualification. Use this part only in non-automotive applications or where automotive compliance is not required.
