Key Parameters

Substitute Part Grouping Explanation

Substitute Zener diodes are grouped based on strict matching of the following key parameters: Voltage - Zener (Nom) (Vz), Tolerance, Power - Max, Impedance (Max) (Zzt), Current - Reverse Leakage @ Vr, Operating Temperature, Mounting Type, and Package / Case. Only devices with identical ratings in these fields and compliant with RoHS3 and REACH requirements are considered as substitute parts. Product status is also used as a critical selection criterion to identify available and active alternatives.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for CD1005-Z3 should be based on product status, ROHS3 compliance, and REACH status. The parts CZRF52C3, CZRF52C3-HF, CZRFR52C3, and CZRFR52C3-HF from Comchip Technology match the required compliance parameters and are available as active products, making them suitable replacements from an engineering, regulatory, and supply chain perspective.

Frequently Asked Questions (FAQ)

Q1: What are the mandatory electrical parameters when selecting a substitute for CD1005-Z3 Zener diodes?
A1: The mandatory parameters are Zener voltage (Vz) of 3 V, tolerance ±5%, power rating of 200 mW, maximum impedance (Zzt) of 95 Ohms, and reverse leakage current of 50 µA @ 1 V.

Q2: What package constraints must be observed for mechanical compatibility?
A2: The substitute Zener diode must be in a 1005 (2512 Metric) package to ensure footprint compatibility with the original CD1005-Z3.

Q3: Does RoHS or REACH compliance affect part interchangeability?
A3: Yes, substitute components must be ROHS3 Compliant and REACH Unaffected to meet environmental compliance requirements for most end applications.

Q4: Are there differences in mounting type among the substitutes listed?
A4: All substitutes utilize the Surface Mount mounting type, identical to the original part.

Q5: Is there any difference in maximum operating temperature between the main part and substitutes?
A5: The operating temperature range is identical across the main and substitute parts, specified as -55°C to 125°C.
