Equivalent & Substitute Parts for Bourns CD0603-Z36 Zener Diode

Part Overview

The Bourns CD0603-Z36 is a surface-mount Zener diode designed for voltage regulation and protection applications. Specified at 36 V nominal Zener voltage with a maximum power dissipation of 150 mW, it is housed in a 0603 (1608 Metric) package suitable for compact electronics. The product is classified as obsolete, necessitating the identification and selection of substitute models that meet the same electrical and mechanical requirements for ongoing production and maintenance activities.

Substitute Part Grouping Explanation

Substitute Zener diodes are determined based on exact matching of electrical and mechanical parameters. The following fields must align for proper substitution: Zener voltage (nominal), tolerance, maximum power, impedance, reverse leakage current at specified voltage, operating temperature range, mounting type, package/case, RoHS/REACH compliance, and moisture sensitivity level. Substitutes listed are direct drop-in replacements with all specified parameters equivalent to the original CD0603-Z36 component.

Engineering Selection Recommendations

The CD0603-Z36 is obsolete; substitute selection is guided by match in electrical ratings, mounting type, and compliance status. All listed substitutes are ROHS3 compliant, maintain the required moisture sensitivity level, and are REACH unaffected. The substitute parts have active product status and identical key parameters, providing direct replacements consistent with original certification and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when selecting a substitute for the CD0603-Z36?
A1: The substitution requires equivalent Zener voltage, tolerance, power rating, impedance, reverse leakage current, operating temperature range, mounting type, package, RoHS compliance, REACH status, and moisture sensitivity level.

Q2: Can the listed substitutes be used in existing CD0603-Z36 layouts?
A2: The mechanical form factor matches the 0603/SOD-523F footprint, meeting the surface-mount and package requirements specified.

Q3: Are all substitute parts compliance-certified equivalent to CD0603-Z36?
A3: All substitutes are classified as ROHS3 compliant and REACH unaffected, matching environmental and regulatory certifications.

Q4: Is there any difference in operational temperature ratings?
A4: All substitutes share an identical operating temperature range of -55°C to 125°C.

Q5: Do substitutes offer the same maximum reverse leakage current?
A5: Each substitute provides a maximum reverse leakage current of 100 nA at 27 V, matching the original specification.
