Key Parameters

Substitute Part Grouping Explanation

Substitutes for CD1005-Z10 are selected strictly on the basis of matching key electrical and mechanical parameters. The allowed criteria for substitution in the Diodes, Zener category are:

• Zener voltage (Vz) must be 10 V nominal
• Tolerance must be ±5% or better
• Maximum power rating must be 200 mW
• Maximum impedance (Zzt) must be 15 Ohms
• Reverse leakage current at reverse voltage must not exceed 100 nA @ specified Vr
• Operating temperature range must be -55°C ~ 125°C
• Package / case must be 1005 (2512 Metric) compatible
• Mounting type must be Surface Mount
• RoHS Compliance and REACH status must match or exceed the main part requirements

Only parts that satisfy all of these parameters are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The CD1005-Z10 is classified as obsolete; all designated substitute parts are active and ROHS3 compliant, with matching MSL and REACH status. Substitutes from Comchip Technology, such as CZRF52C10, CZRF52C10-HF, CZRF10VB, CZRFR52C10, and CZRFR52C10-HF, meet the specified compliance and product status requirements. All substitute Zener diodes listed maintain the required certifications for industrial use.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when substituting CD1005-Z10 Zener diodes?
Selection requires matching Zener voltage, tolerance, power rating, impedance, leakage current, temperature range, mounting type, package/case, RoHS compliance, MSL, and REACH status.

Q2: Are there any tolerance differences among the substitutes?
All substitutes offer ±5% tolerance except CZRF10VB, which has a tighter ±3% tolerance.

Q3: Is the package size and mounting type consistent across all substitutes?
All listed substitute Zener diodes use the 1005 (2512 Metric) package and are designed for surface mount applications.

Q4: Do the substitute parts have differences in compliance or moisture sensitivity?
All substitutes are ROHS3 compliant, feature MSL 1 (Unlimited), and are REACH unaffected.

Q5: Why is it important to use active substitutes?
Active status ensures part availability and long-term manufacturability in place of the obsolete CD1005-Z10.

Q6: What does “100 nA @ 7.5 V” for leakage current mean when selecting substitutes?
This specifies the maximum allowable reverse leakage current under the referenced test voltage for compatibility. All listed substitutes conform to this requirement or present equivalent performance.
