CLL5232D TR Equivalent & Substitute Parts

Part Overview

The CLL5232D TR is a Zener diode rated at 5.6 V nominal with 500 mW power dissipation in a surface mount SOD-80 (DO-213AC, MINI-MELF) package. This component is manufactured by Central Semiconductor Corp and is currently classified as obsolete. Due to its obsolete status and limited availability, identifying equivalent substitute parts is essential for design continuity and procurement planning. The substitute part identified maintains the same core electrical specifications and package form factor, enabling direct replacement in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLL5232D TR is determined by the following critical parameters:

1. Zener Voltage (Vz): Both the main part and substitute maintain 5.6 V nominal specification, ensuring equivalent voltage regulation performance.

2. Power Dissipation (Pmax): Both parts are rated at 500 mW, confirming thermal and electrical load compatibility.

3. Package Form Factor: Both components use SOD-80 (DO-213AC, MINI-MELF) surface mount packaging, enabling mechanical and electrical interchangeability on printed circuit boards.

4. Mounting Type: Both are surface mount devices, compatible with standard SMT assembly processes.

5. Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) classification, indicating identical moisture handling requirements.

The substitute part TZMB5V6-GS08 from Vishay General Semiconductor - Diodes Division satisfies all primary substitution criteria. Secondary parameter variations (tolerance, impedance, leakage current, forward voltage) fall within acceptable ranges for typical Zener diode applications and do not preclude substitution.

Engineering Selection Recommendations

The TZMB5V6-GS08 is the qualified substitute for the obsolete CLL5232D TR based on the following engineering criteria:

Product Status: The CLL5232D TR is obsolete with limited inventory availability. The TZMB5V6-GS08 is an active product with substantial stock levels (134,188 pcs), ensuring long-term procurement viability.

Electrical Equivalence: Both parts maintain identical nominal Zener voltage (5.6 V) and power rating (500 mW). The substitute exhibits superior reverse leakage characteristics (100 nA @ 1 V versus 5 µA @ 3 V), representing improved performance in low-current applications.

Compliance and Certification: The TZMB5V6-GS08 carries AEC-Q101 automotive qualification and ROHS3 compliance, meeting modern regulatory and quality standards. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications.

Package Compatibility: Identical SOD-80 surface mount packaging ensures direct mechanical and electrical interchangeability without PCB redesign.

Temperature Operating Range: The substitute operates across -65°C to 175°C, which covers the majority of industrial and commercial applications. Applications requiring operation above 175°C must be evaluated separately.

Frequently Asked Questions (FAQ)

Q: Can the TZMB5V6-GS08 be used as a direct replacement for the CLL5232D TR?

A: Yes. Both parts share identical nominal Zener voltage (5.6 V), power dissipation (500 mW), and SOD-80 surface mount package. No circuit modifications or PCB redesign are required for substitution.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Tolerance: CLL5232D TR is ±1% versus TZMB5V6-GS08 at ±2%; (2) Impedance: CLL5232D TR is 11 Ohms maximum versus 40 Ohms for the substitute; (3) Reverse leakage: TZMB5V6-GS08 exhibits lower leakage (100 nA @ 1 V); (4) Product status: CLL5232D TR is obsolete while TZMB5V6-GS08 is active; (5) Operating temperature upper limit: CLL5232D TR reaches 200°C while TZMB5V6-GS08 is rated to 175°C.

Q: Does the ±2% tolerance of the substitute affect circuit performance?

A: The tolerance difference (±1% versus ±2%) results in a maximum Zener voltage variation of ±0.112 V for the substitute compared to ±0.056 V for the original part. Circuit designs must accommodate this tolerance band. For applications with strict voltage regulation requirements, tolerance specifications should be verified against circuit design margins.

Q: Is the TZMB5V6-GS08 suitable for automotive applications?

A: Yes. The TZMB5V6-GS08 carries AEC-Q101 automotive qualification, making it suitable for automotive-grade applications. The original CLL5232D TR does not carry this certification.

Q: What is the impact of the higher impedance specification in the substitute?

A: The TZMB5V6-GS08 has a maximum impedance of 40 Ohms compared to 11 Ohms for the CLL5232D TR. Higher impedance results in slightly increased dynamic resistance, which may affect transient response in high-frequency or high-current switching applications. Circuit performance should be validated if the application involves rapid load changes or high-frequency noise filtering.

Q: Can the CLL5232D TR be used in applications requiring operation above 175°C?

A: The CLL5232D TR is rated to 200°C junction temperature, while the TZMB5V6-GS08 is limited to 175°C. For applications requiring operation between 175°C and 200°C, the original part specification must be retained, or alternative substitute parts with higher temperature ratings must be identified.

Q: Are there any moisture handling differences between these parts?

A: No. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited) classification, indicating no moisture-related handling restrictions for either component.

Q: What is the availability status of each part?

A: The CLL5232D TR has 1,123 pcs in stock but is classified as obsolete, indicating no future production. The TZMB5V6-GS08 has 134,188 pcs in stock and is an active product with ongoing availability.
