Substitute Part Grouping Explanation

Substitution is determined strictly by matching the electrical and mechanical parameters essential for function and board compatibility. The allowed parameters for substitution are: category (Diodes, Zener), nominal Zener voltage (2.2 V), tolerance (±5%), maximum power dissipation (150 mW), maximum Zener impedance (100 Ohms), reverse leakage current (100 µA @ 1 V), operating temperature (-55°C ~ 125°C), mounting type (Surface Mount), and package equivalence (0603 or SOD-523F as defined in Supplier Device Package).

Engineering Selection Recommendations

The CD0603-Z2V2 is designated as obsolete, while substitute parts CZRU52C2V2, CZRUR52C2V2, CZRU52C2V2-HF, and CZRUR52C2V2-HF are classified as active and maintain ROHS3 compliance, MSL 1 (Unlimited), and REACH Unaffected status. All alternatives provide full alignment with the original electrical, mechanical, and compliance parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria determine a valid Zener diode substitute in this case?
A1: Substitute validity is based on matching nominal Zener voltage, tolerance, power dissipation, maximum Zener impedance, reverse leakage current, operating temperature range, mounting type, and package equivalence.

Q2: Are the substitute parts compatible with the 0603 (1608 Metric) footprint?
A2: All substitutes list 0603/SOD-523F as the supplier device package and are categorized as surface mount. This aligns with the dimensional requirements specified for a 0603 (1608 Metric) package.

Q3: Are all substitute parts RoHS and REACH compliant?
A3: All listed substitute parts are classified as ROHS3 Compliant and REACH Unaffected.

Q4: How does product status affect component selection?
A4: The main part, CD0603-Z2V2, is obsolete. Substituting with listed active parts ensures continued product availability under equivalent compliance and performance criteria.

Q5: Is there variation in maximum power, Zener voltage, or other critical parameters among substitutes?
A5: All substitute parts match the main part in maximum power rating (150 mW), nominal Zener voltage (2.2 V), tolerance (±5%), maximum impedance (100 Ohms), and reverse leakage current (100 µA @ 1 V).

Q6: Do packaging differences affect electrical or mechanical compatibility?
A6: Packaging is limited to tape & reel format. Mechanical compatibility is preserved by the use of 0603/SOD-523F or equivalent 2-SMD, No Lead packages for all substitutes as specified.
