Key Parameters

Substitute Part Grouping Explanation

Equivalents and substitutes are strictly determined by matching all provided electrical and mechanical parameters relevant for Zener diode selection:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Power - Max
• Impedance (Max) (Zzt)
• Current - Reverse Leakage @ Vr
• Operating Temperature Range
• Mounting Type
• Package / Case
• Compliance (RoHS, REACH)
• Moisture Sensitivity Level (MSL)

Parts in the substitute list match the specified values for each above parameter and belong to the same "Diodes, Zener" category, ensuring direct compatibility.

Parameter Comparison

Engineering Selection Recommendations

Given the obsolete status of the Bourns Inc. CD1005-Z33, substitute selection is based on matching electrical characteristics, surface mount form factor, and package similarity. All listed substitute parts from Comchip Technology provide equivalent Zener voltage, power, impedance, reverse leakage, operating temperature range, packaging, RoHS3 compliance, unlimited MSL, and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting the CD1005-Z33 Zener diode?
A1: Substitution requires identical Zener voltage (33 V), ±5% tolerance, 200 mW max power, 80 Ohms max impedance, 100 nA reverse leakage at 25 V, matching operating temperature (-55°C ~ 125°C), surface mount, and 1005 (2512 Metric) packaging.

Q2: Are the substitute parts compliant with RoHS and REACH standards?
A2: All listed substitute parts are ROHS3 compliant and REACH unaffected.

Q3: Will substituting with one of the listed Comchip Technology parts affect my design's mounting or moisture specifications?
A3: No. The substitute parts provide the same mounting type (surface mount), identical package/case (1005/2512 Metric), and MSL 1 (unlimited).

Q4: Is it necessary to evaluate substitute parts for electrical compatibility?
A4: The substitute parts match all allowed electrical parameters for direct substitution as specified.

Q5: Are there any differences in the supplier device package designations?
A5: The substitute parts specify 1005/SOD-323F; however, based strictly on the provided parameters, this matches the required 1005 (2512 Metric) package criteria.
