CLL4696 TR Equivalent & Substitute Parts

Part Overview

The CLL4696 TR is a Zener diode manufactured by Central Semiconductor Corp, rated at 9.1 V nominal with 500 mW maximum power dissipation. The device is packaged in SOD-80 (DO-213AC, MINI-MELF) surface mount configuration and operates across a temperature range of -65°C to 200°C. This part is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support, repair operations, and new production requirements where equivalent electrical performance is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLL4696 TR is determined by matching the following critical electrical and mechanical parameters:

Electrical Matching Criteria:

• Zener voltage: 9.1 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 500 mW
• Reverse leakage current: 1 µA @ 6.9 V
• Forward voltage: 1.5 V @ 100 mA

Mechanical Matching Criteria:

• Surface mount configuration
• Package compatibility with circuit board layout

The CMHZ4696 TR qualifies as a direct substitute based on identical electrical specifications. Package differences (SOD-123 versus SOD-80) represent the primary distinction and require physical board layout verification. The CMHZ4696 TR maintains active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The CMHZ4696 TR is the primary substitute for the obsolete CLL4696 TR. Both components share identical electrical specifications across all critical parameters: 9.1 V zener voltage, ±5% tolerance, 500 mW power rating, and matching forward and reverse leakage characteristics.

The CMHZ4696 TR offers the advantage of active product status, ensuring availability through standard distribution channels and long-term supply continuity. The component carries identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications, maintaining regulatory compliance equivalence.

The primary design consideration is package footprint transition from SOD-80 to SOD-123. Both are surface mount configurations with different physical dimensions and land patterns. Circuit board layout modification is required to accommodate the SOD-123 package. The operating temperature range of the CMHZ4696 TR extends to 150°C maximum junction temperature, compared to 200°C for the CLL4696 TR. Applications operating above 150°C junction temperature require thermal analysis to confirm suitability.

Frequently Asked Questions (FAQ)

Q: Can the CMHZ4696 TR directly replace the CLL4696 TR without circuit modification?

A: Electrical substitution is direct. Physical board layout modification is required due to package differences between SOD-80 and SOD-123. Land pattern, trace routing, and component placement must be updated to accommodate the SOD-123 footprint.

Q: What is the primary reason for substituting the CLL4696 TR?

A: The CLL4696 TR is classified as obsolete. The CMHZ4696 TR provides equivalent electrical performance with active product status and assured supply availability.

Q: Are the electrical specifications identical between CLL4696 TR and CMHZ4696 TR?

A: All critical electrical parameters are identical: 9.1 V zener voltage, ±5% tolerance, 500 mW power dissipation, 1 µA reverse leakage current, and 1.5 V forward voltage. Operating temperature ranges differ: CLL4696 TR operates to 200°C; CMHZ4696 TR operates to 150°C.

Q: Does the temperature range difference affect substitution suitability?

A: Applications with maximum junction temperatures below 150°C experience no thermal limitation. Designs requiring operation above 150°C require thermal analysis to confirm the CMHZ4696 TR remains within acceptable operating margins.

Q: Are regulatory and compliance classifications maintained with the CMHZ4696 TR?

A: Yes. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications, maintaining regulatory equivalence.

Q: What package considerations apply to the SOD-123 configuration?

A: SOD-123 is a smaller surface mount package than SOD-80. Board layout redesign is necessary. Verify component placement clearances, trace routing, and thermal management provisions for the new footprint.
