Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key electrical and mechanical parameters. These include product category (Diodes, Zener), configuration (1 Pair Common Anode), Zener voltage (18 V nominal), mounting type (Surface Mount), package/case, power rating, tolerance, and compliance statuses (ROHS, REACH). Substitute parts must align with these parameters for functional and regulatory compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both UMZ18NT106 and AZ23C18-7-F are listed as Active and are compliant with ROHS3 and unaffected by REACH regulation. Selection between these parts depends strictly on supplied compliance, package options, and matching electrical parameters as stated. There are no regulatory distinctions between them based on the provided certifications.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting Zener diode arrays?
A1: Substitute selection is strictly based on matching the category, Zener voltage, tolerance, power rating, configuration, mounting type, package or case, and compliance parameters as provided.

Q2: Are the package/case options interchangeable between UMZ18NT106 and AZ23C18-7-F?
A2: Both parts are surface mount but feature different case options: UMZ18NT106 uses SC-70, SOT-323, while AZ23C18-7-F uses TO-236-3, SC-59, SOT-23-3. Compatibility must be determined based on specific mechanical envelope requirements.

Q3: Does compliance status affect part substitution?
A3: Both parts are ROHS3 compliant and REACH unaffected. These statuses allow substitution where regulatory compliance must be maintained.

Q4: Is electrical configuration identical for both parts?
A4: Yes. Both are configured as 1 Pair Common Anode Zener Diode Arrays with a nominal voltage of 18 V.

Q5: Are there differences in tolerance and power ratings that should be considered?
A5: UMZ18NT106 has a tolerance of ±2.19% and power rating of 200 mW; AZ23C18-7-F has ±5% and 300 mW respectively. Selection must adhere to the tolerances required by the application.
