Substitute Part Grouping Explanation

Substitution of the SF63G-TP is determined by strict equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage must equal 150 V
Current Rating: Average rectified current must equal 6 A
Forward Voltage Drop: Maximum forward voltage at rated current must equal 975 mV @ 6 A
Reverse Recovery Time: Must equal 35 ns (fast recovery classification)
Reverse Leakage Current: Must equal 5 µA @ 150 V
Package and Mounting: Must be DO-201AD axial through-hole configuration
Operating Temperature Range: Must support -55°C to 150°C junction temperature

Substitute parts are grouped into two categories based on these parameters and additional qualifications:

Category 1: Direct Parametric Equivalent — Parts matching all electrical and mechanical specifications with standard industrial qualification.

Category 2: Automotive-Qualified Equivalent — Parts matching all electrical and mechanical specifications with automotive-grade qualification (AEC-Q101).

Engineering Selection Recommendations

For Standard Industrial Applications:

The SF63G (Taiwan Semiconductor Corporation) is a direct parametric equivalent to the SF63G-TP. Both parts share identical electrical specifications, including voltage rating, current capacity, forward voltage drop, and reverse recovery characteristics. The SF63G maintains active product status, ensuring continued availability and supply chain support. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1). Selection of SF63G is appropriate for applications where standard industrial-grade qualification is sufficient.

For Automotive and High-Reliability Applications:

The SF63GH (Taiwan Semiconductor Corporation) is an automotive-qualified variant meeting AEC-Q101 qualification standards. This part maintains all electrical and mechanical equivalence to the SF63G-TP while providing enhanced qualification for automotive and mission-critical applications. The SF63GH is recommended for designs requiring automotive-grade components or where AEC-Q101 certification is a contractual or regulatory requirement.

Packaging Consideration:

The SF63G-TP is supplied in Tape & Reel (TR) packaging. The SF63G substitute is available in Cut Tape (CT) packaging. The SF63GH packaging specification is not provided in available data. Packaging format selection should be based on assembly process requirements and volume specifications.

Frequently Asked Questions (FAQ)

Q: Can SF63G or SF63GH be used as direct replacements for SF63G-TP in existing designs?

A: Yes. Both SF63G and SF63GH meet all critical electrical parameters: 150 V reverse voltage, 6 A average rectified current, 975 mV forward voltage drop at 6 A, 35 ns reverse recovery time, and 5 µA reverse leakage current. Both are packaged in DO-201AD axial through-hole configuration and operate across the same temperature range (-55°C to 150°C). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between SF63G and SF63GH?

A: The SF63G and SF63GH are electrically and mechanically identical. The SF63GH carries AEC-Q101 automotive qualification, making it suitable for automotive applications and high-reliability systems. The SF63G is standard industrial grade. Selection between these parts depends on application requirements and qualification standards.

Q: Why is the SF63G-TP marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status with the original manufacturer (Micro Commercial Co). New designs should not be initiated using this part number. Existing designs using SF63G-TP should transition to active alternatives such as SF63G or SF63GH to ensure long-term supply availability and support.

Q: Are there differences in capacitance between the main part and substitutes?

A: The SF63G-TP specifies 120 pF @ 4V, 1MHz, while both SF63G and SF63GH specify 100 pF @ 4V, 1MHz. This 20 pF difference is within typical manufacturing tolerance for general-purpose rectifier diodes and does not affect functional equivalence in standard rectification applications. Applications with specific capacitance requirements should evaluate this parameter against circuit design specifications.

Q: What packaging formats are available for these substitutes?

A: The SF63G-TP is supplied in Tape & Reel (TR) format. The SF63G substitute is available in Cut Tape (CT) format. Packaging selection should align with assembly equipment and production volume requirements. Contact the supplier for availability of alternative packaging formats.

Q: Are all three parts RoHS compliant?

A: Yes. The SF63G-TP, SF63G, and SF63GH are all ROHS3 compliant and carry REACH Unaffected status. All parts are suitable for applications requiring RoHS compliance.

Q: What is the inventory status of these parts?

A: The SF63G-TP has 729 pieces in stock. The SF63G has 3,320 pieces in stock. The SF63GH has 696 pieces in stock. Inventory levels should be confirmed with the supplier for current availability and lead time information.
