Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD411699B is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Maximum DC reverse voltage must equal or exceed 1600 V
• Current Rating: Average rectified current per diode must equal or exceed 100 A
• Diode Configuration: Must maintain 1 Pair Series Connection topology
• Technology Class: Must be Standard technology classification
• Recovery Speed: Must meet Standard Recovery >500ns, > 200mA (Io) specification
• Mounting Interface: Must support Chassis Mount configuration
• Reverse Leakage: Must not exceed specified maximum at rated voltage

The CD411699C qualifies as a direct substitute based on full parameter alignment across all electrical and mechanical specifications. Both components share identical base product number CD411699, confirming design compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD411699C is the qualified substitute for CD411699B based on the following factors:

Product Status Alignment: The CD411699C is classified as Active, providing assured supply availability and ongoing manufacturer support. The CD411699B is obsolete, making the CD411699C the appropriate long-term replacement for new designs and production continuity.

Electrical Specification Compliance: The CD411699C maintains full electrical equivalence across all critical parameters: 1600 V reverse voltage rating, 100 A average rectified current per diode, and standard recovery speed characteristics. The reverse leakage current of 8 mA at 1600 V is lower than the CD411699B specification of 10 mA, representing improved performance within acceptable design margins.

Regulatory and Compliance Status: The CD411699C carries RoHS3 Compliance certification, meeting current environmental and regulatory requirements. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, confirming equivalent export and tariff treatment.

Mechanical and Thermal Compatibility: Both components utilize identical chassis mount configuration and POW-R-BLOK™ module packaging, ensuring direct mechanical interchangeability. The CD411699C specifies operating junction temperature range of -40°C to 150°C, providing defined thermal operating boundaries.

Inventory and Supply: The CD411699C maintains substantial inventory availability (5400 pieces in stock), supporting immediate procurement requirements.
