Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DBL101G C1G are identified based on electrical and mechanical parameter equivalence. The substitution logic is structured as follows:

Direct Manufacturer Equivalent: Parts sharing identical electrical specifications, package configuration, and mounting type without additional qualifications or grade designations.

Parametric Equivalent: Parts meeting all core electrical parameters and physical package requirements but incorporating additional qualifications such as automotive-grade certification or enhanced reliability standards.

The critical parameters determining substitutability are:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 2 µA @ 50 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Package / Case: 4-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
