Substitute Part Grouping Explanation

Substitution of the SF63GH is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SF63G maintains identical performance specifications including reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, reverse leakage current, and junction temperature range. Both parts employ standard rectifier technology with fast recovery characteristics and are housed in the DO-201AD axial through-hole package.

The primary distinction between SF63GH and SF63G is the packaging format: SF63GH is supplied in standard packaging, while SF63G is supplied in cut tape (CT) format. This difference does not affect electrical performance or mechanical compatibility in circuit applications. Both parts are manufactured by Taiwan Semiconductor Corporation, carry AEC-Q101 automotive qualification, and comply with ROHS3, REACH, and moisture sensitivity requirements.

Substitution is valid when the following parameters are matched:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 6 A
• Voltage - Forward (Vf) (Max) @ If: 975 mV @ 6 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 150 V
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C

Parameter Comparison

Engineering Selection Recommendations

Both SF63GH and SF63G are active production parts manufactured by Taiwan Semiconductor Corporation with identical electrical specifications and mechanical compatibility. Selection between these parts is based on packaging and supply requirements rather than performance differences.

SF63GH is appropriate for applications requiring standard packaging format with current inventory of 696 pieces available.
