Key Parameters

Substitute Part Grouping Explanation

Substitutes are determined on the basis of strictly matching key electrical and mechanical parameters critical for interchangeability in the zener diode category. The following parameters are matched: nominal Zener voltage (22 V), voltage tolerance (±5%), maximum power dissipation (200 mW), maximum impedance (55 Ohms), reverse leakage current at test voltage (100 nA @ 17 V), identical surface mount package and footprint (1005/2512 Metric), and identical operating temperature range (−55°C to +125°C). Compliance with RoHS and REACH, as well as MSL and supply chain status, are required for selection.

Parameter Comparison

Engineering Selection Recommendations

Given the obsolete status of Bourns CD1005-Z22 and the active status of its listed substitutes (CZRF52C22, CZRF52C22-HF, CZRFR52C22, CZRFR52C22-HF), priority should be given to active devices for design continuity. All substitutes are ROHS3 compliant, REACH unaffected, and rated at MSL 1 (Unlimited), matching required compliance and environmental certifications.

Frequently Asked Questions (FAQ)

Q: What makes a diode, zener, part number suitable as a substitute for CD1005-Z22?
A: A substitute is suitable only if it matches the voltage (22 V), tolerance (±5%), power dissipation (200 mW), impedance (55 Ohms), reverse leakage current (100 nA @ 17 V), operating temperature (−55°C to +125°C), mounting type (surface mount), and package/case (1005/2512 Metric).

Q: Do these substitute zener diodes offer the same performance and fit as CD1005-Z22?
A: All listed substitutes present identical parameter values and package form factor as provided, ensuring consistent functional performance and mechanical fit.

Q: Are the substitutes compliant with RoHS and REACH standards?
A: Yes. All listed substitute zener diodes are ROHS3 compliant and REACH unaffected as specified.

Q: Why is finding a substitute necessary for CD1005-Z22?
A: The original Bourns CD1005-Z22 is obsolete, requiring selection of a functionally and mechanically equivalent active part to maintain device availability.

Q: Do package or supplier device package differences affect substitution in this case?
A: All models are in the 1005 (2512 Metric) surface mount package as detailed, maintaining consistent PCB layout compatibility.
