Substitute Part Grouping Explanation

Substitution of the CLL4689 TR is determined by the following critical parameters:

Electrical Equivalence Criteria:

Voltage - Zener (Nom): 5.1 V
Power - Max: 500 mW
Tolerance: ±5%
Mounting Type: Surface Mount

Mechanical Compatibility Criteria:

Package / Case: SOD-80 (DO-213AC, MINI-MELF)

Substitute parts are grouped into two categories based on package compatibility:

Category 1: SOD-80 Package (Direct Mechanical Substitutes) Parts maintaining the identical SOD-80 package footprint and all electrical parameters within specification.

Category 2: SOD-123 Package (Functional Equivalent, Different Package) Parts with identical electrical specifications but different surface mount package, requiring PCB layout modification.

Engineering Selection Recommendations

For Direct Mechanical and Electrical Substitution (SOD-80 Package):

The following parts are recommended as primary substitutes for the obsolete CLL4689 TR, maintaining identical SOD-80 package compatibility:

TZM5231B-GS18 (Vishay): Active status, ±5% tolerance matching, 500 mW power rating, SOD-80 package. Suitable for general applications with operating temperature range to 175°C.
TZMC5V1-M-08 and TZMC5V1-M-18 (Vishay): Active status, AEC-Q101 automotive qualification, ±5% tolerance, 500 mW power rating, SOD-80 package. Recommended for automotive and high-reliability applications requiring formal qualification.
TLZ5V1C-GS08 and TLZ5V1C-GS18 (Vishay): Active status, 500 mW power rating, SOD-80 package, ROHS3 compliant. Suitable for commercial applications with operating temperature range to 175°C.

For Functional Equivalence with Package Change (SOD-123 Package):

CMHZ4689 TR (Central Semiconductor Corp): Active status, same manufacturer as original part, ±5% tolerance, 500 mW power rating. Requires PCB layout modification due to SOD-123 package. Operating temperature range limited to 150°C.

Compliance Considerations:

All recommended Vishay substitutes carry ROHS3 compliance and REACH Unaffected status. The TZMC5V1-M series provides AEC-Q101 automotive qualification for applications requiring formal component qualification.

Frequently Asked Questions (FAQ)

Q: Can I use CMHZ4689 TR as a direct replacement for CLL4689 TR?

A: CMHZ4689 TR is electrically equivalent (5.1 V, 500 mW, ±5% tolerance) but uses SOD-123 package instead of SOD-80. This requires PCB layout modification and cannot be used as a direct drop-in replacement. The operating temperature range is also reduced to -65°C ~ 150°C compared to the original -65°C ~ 200°C.

Q: What is the difference between TLZ5V1 and TZM5231B series?

A: Both series are 5.1 V, 500 mW Zener diodes in SOD-80 package from Vishay. The TLZ5V1 series does not specify tolerance in the provided data, while TZM5231B series specifies ±5% tolerance matching the original CLL4689 TR. The TZM5231B-GS18 is recommended for applications requiring explicit tolerance specification.

Q: Are TZMC5V1-M parts suitable for my application?

A: TZMC5V1-M-08 and TZMC5V1-M-18 are automotive-grade parts with AEC-Q101 qualification. These are suitable for any application, with particular advantage in automotive and high-reliability environments. They maintain 5.1 V nominal, 500 mW power rating, ±5% tolerance, and SOD-80 package compatibility.

Q: What does the suffix (-08, -18, -GS08, -GS18) indicate?

A: The suffixes indicate tape and reel packaging configurations and quantity per reel. Both -08 and -18 variants are functionally identical in electrical and mechanical specifications. Selection between them depends on procurement quantity requirements and inventory management.

Q: Can I use these substitutes in high-temperature applications?

A: The original CLL4689 TR operates to 200°C. Most active substitutes operate to 175°C maximum. For applications requiring operation above 175°C, verify that the substitute part's maximum operating temperature meets your specific thermal requirements.

Q: Are all recommended substitutes RoHS compliant?

A: All Vishay substitutes (TLZ5V1, TZM5231B, TZMC5V1-M series) are ROHS3 compliant. CMHZ4689 TR compliance status is not specified in the provided data.
