Engineering Selection Recommendations

Primary Recommendation: TZM5232B-GS18

The TZM5232B-GS18 provides the closest electrical match to the CLL5232B BK. This part maintains identical nominal voltage (5.6 V), tolerance (±5%), power rating (500 mW), impedance (11 Ohms), and reverse leakage current (5 µA @ 3 V) specifications. The forward voltage is improved at 1.1 V versus 1.25 V. The part is ROHS3 compliant and carries active product status with substantial inventory availability (131100 pieces). Operating temperature specification is not provided in the datasheet but does not restrict substitution.

Secondary Recommendation: TZM5232B-GS08

The TZM5232B-GS08 offers identical electrical performance to TZM5232B-GS18 with the exception of impedance specification (not provided). This variant is available in Cut Tape & Digi-Reel packaging with 30400 pieces in stock. Selection between GS08 and GS18 variants depends on procurement and assembly requirements.

Alternative Recommendations: TLZ5V6 Series (TLZ5V6A, TLZ5V6B, TLZ5V6C)

The TLZ5V6 series variants (A, B, C) with GS08 and GS18 packaging options provide functional substitution with acceptable parameter variations. These parts maintain 5.6 V nominal voltage and 500 mW power rating. Impedance increases to 13 Ohms (acceptable within tolerance), forward voltage increases to 1.5 V @ 200 mA, and reverse leakage improves to 1 µA @ 2 V. Operating temperature range is -65°C to 175°C. All variants are ROHS3 compliant with active product status. TLZ5V6B-GS08 offers the highest inventory availability at 118550 pieces.

Compliance Status:

All substitute parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8541.10.0050. Moisture sensitivity level is 1 (Unlimited) for all parts.

Frequently Asked Questions (FAQ)

Q: Can TLZ5V6A-GS08 directly replace CLL5232B BK in all applications?

A: TLZ5V6A-GS08 meets the primary electrical requirements (5.6 V nominal, 500 mW power, SOD-80 package). Parameter variations include impedance increase from 11 Ohms to 13 Ohms and forward voltage increase from 1.25 V to 1.5 V @ 200 mA. These variations are within acceptable substitution tolerances for standard zener diode applications. Operating temperature range is reduced from -65°C to 200°C to -65°C to 175°C.

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

A: GS08 and GS18 designations indicate different tape reel configurations for surface mount assembly. GS08 typically represents 8mm tape width, while GS18 represents 18mm tape width. Both variants contain identical electrical components in SOD-80 MiniMELF packages. Selection depends on pick-and-place equipment compatibility and procurement preferences.

Q: Why is TZM5232B-GS18 recommended over TLZ5V6 variants?

A: TZM5232B-GS18 maintains all critical electrical parameters identical to the original CLL5232B BK, including ±5% tolerance, 11 Ohms impedance, and 5 µA @ 3 V reverse leakage current. TLZ5V6 variants introduce parameter variations in impedance, forward voltage, and reverse leakage. When exact parameter matching is required, TZM5232B-GS18 is the preferred choice.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. The original CLL5232B BK requires inventory verification for RoHS status.

Q: What is the inventory advantage of selecting TLZ5V6B-GS08?

A: TLZ5V6B-GS08 has 118550 pieces in stock, representing the highest availability among all substitute options. This variant is suitable for applications where parameter variations in impedance (13 Ohms), forward voltage (1.5 V @ 200 mA), and reverse leakage (1 µA @ 2 V) are acceptable.

Q: Can I use TLZ5V6-GS08 or TLZ5V6-GS18 without tolerance specification?

A: TLZ5V6-GS08 and TLZ5V6-GS18 do not specify tolerance in the provided data. These parts are suitable for applications where tolerance specification is not critical. For applications requiring ±5% tolerance matching, TZM5232B series or CLL5232B BK are appropriate selections.

Q: What is the operating temperature consideration for substitute selection?

A: The original CLL5232B BK operates from -65°C to 200°C. TLZ5V6 series variants operate from -65°C to 175°C, representing a 25°C reduction in maximum operating temperature. TZM5232B-GS08 does not specify operating temperature range. For applications requiring operation above 175°C, verify compatibility with specific circuit requirements.

Q: Are all parts classified under the same HTSUS and ECCN codes?

A: Yes. All parts listed, including the original CLL5232B BK and all substitute options, are classified under HTSUS code 8541.10.0050 and ECCN EAR99. This ensures consistent regulatory treatment for procurement and export purposes.
