Substitute Part Grouping Explanation

Substitute parts for the TS20P03G D2G bridge rectifier are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 20 A
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Operating Temperature Range: -55°C to 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: 4-SIP, TS-6P

Substitute parts meeting all electrical and mechanical parameters are classified as direct equivalents and parametric equivalents. Parts with identical specifications but different product status or certifications are listed separately to support design flexibility and supply chain alternatives.
