Engineering Selection Recommendations

Both SF47G A0G and 1N5405-E3/54 are active, ROHS3 compliant, and have REACH-unaffected status. Both are through-hole DO-201AD packages with unlimited moisture sensitivity rating (MSL 1). Substitute selection can be determined by matching the compliance requirements and ensuring the package and product status align with design constraints.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters when selecting a substitute rectifier diode for SF47G A0G?
A: Maximum reverse voltage, average rectified current, package type (DO-201AD), mounting style, ROHS status, and MSL must be matched.

Q: Is the package form factor identical between SF47G A0G and 1N5405-E3/54?
A: Both diodes utilize the DO-201AD axial through-hole package.

Q: Are there differences in electrical characteristics that should be considered?
A: Substitute selection must align maximum voltage and current ratings as well as mechanical compatibility. The substitute provided matches the reverse voltage and package, with a current rating of 3A compared to 4A for the original.

Q: What compliance standards do both parts meet?
A: Both SF47G A0G and 1N5405-E3/54 are ROHS3 compliant, REACH unaffected, and rated MSL 1 (unlimited).

Q: Is there a difference in inventory or availability between these parts?
A: Both parts are listed as actively available and new original stock, supporting continuity of supply chain.
