Substitute Part Grouping Explanation

Substitute parts for the DBL151G C1G are identified based on electrical and mechanical parameter equivalence. The substitution logic is structured as follows:

Direct Equivalence Criteria:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parametric Equivalence Criteria: Parts meeting all direct equivalence criteria with additional qualifications (such as automotive-grade certification per AEC-Q101) are classified as parametric equivalents. These parts maintain full electrical and mechanical compatibility while offering enhanced reliability for specific application environments.
