Substitute Part Grouping Explanation

Substitute parts for the CDLL0.2A40 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40V
• Current - Average Rectified (Io): 200mA
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 200 mA
• Current - Reverse Leakage @ Vr: 5 µA @ 40 V
• Capacitance @ Vr, F: 50pF @ 0V, 1MHz
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Equivalence Criteria:

• Package / Case: DO-213AA
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 125°C

Parts meeting all of these criteria are classified as parametric equivalents and direct substitutes.
