Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDBUR0130 are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is determined by the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 30V
• Current - Average Rectified (Io): 100mA
• Voltage - Forward (Vf) (Max) @ If: 440 mV @ 100 mA
• Current - Reverse Leakage @ Vr: 30 µA @ 30 V
• Capacitance @ Vr, F: 9pF @ 10V, 1MHz
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 2-SMD, No Lead
• Supplier Device Package: 0603/SOD-523F or 0603C/SOD-523F

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• Operating Temperature - Junction (Max): 125°C

All identified substitute parts maintain identical electrical performance, thermal ratings, and regulatory compliance. Packaging variants (0603 vs. 0603C) are functionally equivalent within the SOD-523F form factor specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CDBUR0130, CDBU0130, and CDBU0130-HF—are active products from Comchip Technology with identical electrical specifications, thermal ratings, and regulatory compliance. Selection between these parts is based on the following engineering criteria:
