Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for the CLL4697 BK is strictly determined by matching the core electrical and mechanical parameters: nominal Zener voltage, tolerance, maximum power dissipation, reverse leakage current at specified voltage, maximum forward voltage at specified current, operating temperature range, mounting type, package/case, and supplier device package. Only devices meeting or exceeding the performance and form factor requirements are considered equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between CLL4697 BK and CMHZ4697 BK can be based on product status and compliance. CLL4697 BK is obsolete, while CMHZ4697 BK is active and REACH unaffected. Substitute parts listed under CMHZ4697 BK are also available in SOD-123 surface-mount packages.

Frequently Asked Questions (FAQ)

Q: What criteria are used to select a substitute for the CLL4697 BK Zener diode?
A: Substitute selection is based on matching nominal Zener voltage, tolerance, maximum power dissipation, reverse leakage current, forward voltage, operating temperature range, mounting type, and package/case as provided in the parameters.

Q: Are alternate packages like SOD-123 compatible with the original SOD-80 footprint?
A: The package/case specifications must match the required mechanical layout for the circuit. SOD-123 and SOD-80 are both surface-mount packages but differ in pin configuration and size; mechanical compatibility must be assured at the board level.

Q: Does a change in product status affect suitability as a replacement?
A: Product status is a consideration for lifecycle management. The CLL4697 BK is obsolete. Substitutes like CMHZ4697 BK retain active product status, ensuring ongoing availability.

Q: Are there differences in operating temperature ranges among listed substitutes?
A: The CLL4697 BK supports -65°C ~ 200°C (TJ), while substitutes such as CMHZ4697 BK specify -65°C ~ 150°C (TJ). This difference is documented in the parameter comparison.

Q: Do reverse leakage and forward voltage values need to match exactly?
A: Only parts with specified equal or superior reverse leakage and forward voltage values, as provided in the comparison, are considered direct substitutes.
