CLL4690 TR Equivalent & Substitute Parts

Part Overview

The CLL4690 TR is a Zener diode rated at 5.6 V nominal with 500 mW power dissipation in SOD-80 (MINI-MELF) surface mount packaging. Manufactured by Central Semiconductor Corp, this component is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, equivalent substitute parts are necessary for new designs and ongoing production requirements. Substitute components maintain the core electrical specifications while offering improved product status, compliance certifications, and extended availability.

Engineering Selection Recommendations

For Direct Replacement (Identical Package and Electrical Specifications):

The Vishay General Semiconductor TZMC5V6-GS08 and TZMC5V6-GS18 provide the closest electrical match to the CLL4690 TR. Both maintain 5.6 V nominal, ±5% tolerance, 500 mW power rating, and SOD-80 packaging. These parts are active products with RoHS3 compliance and AEC-Q101 automotive qualification. The TZMC5V6-GS08 and TZMC5V6-M-08 variants offer extended temperature range (-65°C to 175°C) and lower reverse leakage current (100 nA @ 1 V versus 10 µA @ 4 V), providing improved performance margins.

For Tighter Tolerance Requirements:

The TZMB5V6-GS08 and TZMB5V6-GS18 offer ±2% tolerance versus the ±5% specification of the CLL4690 TR. These parts maintain identical voltage and power ratings in SOD-80 packaging with active product status, RoHS3 compliance, and AEC-Q101 qualification. Operating temperature range extends to -65°C to 175°C with significantly lower reverse leakage (100 nA @ 1 V).

For Alternative Packaging (SOD-123):

The CMHZ4690 TR from Central Semiconductor Corp provides electrical equivalence with identical voltage, tolerance, and power specifications. However, this part uses SOD-123 packaging rather than SOD-80, requiring PCB layout modification. Operating temperature range is -65°C to 150°C. This option is suitable only when package footprint change is acceptable.

For General-Purpose Applications:

The Vishay TLZ5V6-GS08 and TLZ5V6-GS18 are active products in SOD-80 packaging with 5.6 V / 500 mW specifications. These parts lack specified tolerance and reverse leakage parameters but offer -65°C to 175°C operating range and RoHS3 compliance.

All recommended substitutes are active products with current availability and compliance certifications suitable for production use.

Frequently Asked Questions (FAQ)

Q: Can the CLL4690 TR be directly replaced with TZMC5V6-GS08?

A: Yes. Both parts maintain 5.6 V nominal voltage, ±5% tolerance, 500 mW power dissipation, and SOD-80 packaging. The TZMC5V6-GS08 is an active product with improved specifications including lower reverse leakage current and extended temperature range to 175°C. No circuit modification is required.

Q: What is the difference between TZMC5V6-GS08 and TZMB5V6-GS08?

A: Both parts are 5.6 V / 500 mW Zener diodes in SOD-80 packaging from Vishay. The primary difference is tolerance: TZMC5V6-GS08 is ±5% while TZMB5V6-GS08 is ±2%. The TZMB variant also features lower reverse leakage current (100 nA @ 1 V versus 100 nA @ 1 V for TZMC). Both are AEC-Q101 qualified automotive-grade components.

Q: Why is CMHZ4690 TR listed as a substitute if it uses different packaging?

A: CMHZ4690 TR provides electrical equivalence to the CLL4690 TR with identical voltage, tolerance, and power specifications. However, it uses SOD-123 packaging instead of SOD-80. This part is listed for applications where package footprint change is acceptable or where SOD-80 alternatives are unavailable. PCB layout modification is required for implementation.

Q: Are all substitute parts RoHS3 compliant?

A: All Vishay substitute parts listed (TLZ5V6, TZM5232B, TZMB5V6, TZMC5V6 series) are RoHS3 compliant. The Central Semiconductor CMHZ4690 TR does not specify RoHS status in the provided data. Verify compliance requirements for your specific application before selection.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 qualification indicates the component meets automotive industry reliability and quality standards. Parts bearing this qualification (TZMB5V6 and TZMC5V6 series) are suitable for automotive and high-reliability applications. Non-qualified parts (TLZ5V6, TZM5232B) are suitable for general industrial and consumer applications.

Q: Can I use TLZ5V6-GS08 as a direct replacement for CLL4690 TR?

A: TLZ5V6-GS08 maintains 5.6 V / 500 mW specifications in SOD-80 packaging and is an active product. However, tolerance and reverse leakage current specifications are not provided in the datasheet. Use this part only when tolerance and leakage specifications are not critical to circuit performance.

Q: What is the difference between -GS08 and -GS18 packaging designations?

A: Both designations indicate SOD-80 MiniMELF packaging. The -GS08 and -GS18 suffixes denote different tape reel configurations (8mm and 18mm reel widths respectively) for automated assembly. Electrical specifications are identical; selection depends on assembly equipment compatibility.

Q: Is the operating temperature range of 175°C sufficient for applications requiring 200°C operation?

A: No. The CLL4690 TR specifies -65°C to 200°C operating range. All listed Vishay substitutes limit operation to 175°C maximum. For applications requiring 200°C operation, alternative components outside this substitute list must be evaluated.

Q: What is the advantage of lower reverse leakage current in TZMB5V6 and TZMC5V6 variants?

A: Lower reverse leakage current (100 nA @ 1 V versus 10 µA @ 4 V) reduces standby power consumption and improves circuit stability in precision applications. This specification is particularly important in low-power and high-impedance circuits where leakage current directly impacts performance.
