Key Parameters

Substitute Part Grouping Explanation

Substitution for the CDLL967B Zener diode is established strictly on the following key parameters: voltage - Zener (nominal 18 V), tolerance (±5%), power rating (500 mW), reverse leakage current at specified voltage, forward voltage at specified current, mounting type (surface mount), and package compatibility. Electrical parameters are matched to maintain function, with mechanical compatibility ensured through surface mount package form factors in the MELF/MiniMELF/SOD-80 outline.

Parameter Comparison

Engineering Selection Recommendations

The CDLL967B is RoHS non-compliant, while the substitute TZM5248B-GS08 is ROHS3 compliant. Both diodes are classified as moisture sensitivity level 1 (unlimited), unaffected by REACH, and hold similar ECCN and HTSUS classifications. Adherence to compliance requirements, including RoHS and REACH status, should be a determining factor in selection for environmentally regulated environments.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when substituting Zener diodes in the DO-213AB/MELF and SOD-80 MiniMELF categories?
A1: Voltage - Zener (Nom), tolerance, power rating, reverse leakage at specified voltage, forward voltage at specified current, mounting type, and package compatibility.

Q2: Is the TZM5248B-GS08 suitable as a direct functional substitute for the CDLL967B?
A2: Based on the matching key electrical parameters and surface mount format, the TZM5248B-GS08 is categorized as a valid substitute.

Q3: How does package type affect substitution between the CDLL967B and TZM5248B-GS08?
A3: The CDLL967B uses a DO-213AB MELF surface-mount package, while the TZM5248B-GS08 offers DO-213AC/MiniMELF/SOD-80; these case outlines are mechanically compatible within the MiniMELF/MELF group for standard assembly processes.

Q4: What compliance differences exist between these Zener diodes?
A4: The CDLL967B is RoHS non-compliant, whereas the TZM5248B-GS08 is ROHS3 Compliant. Both are unaffected by REACH regulations.

Q5: Why substitute Zener diodes in an assembly or design?
A5: Substitution is done when electrical performance, mechanical mounting, and compliance parameters are equivalent, ensuring procurement flexibility or alignment with environmental directives.
