CDLL965A Equivalent & Substitute Parts Reference

Part Overview

The Microchip Technology CDLL965A is a Zener Diode rated for 15 V nominal Zener voltage, 500 mW maximum power dissipation, and housed in a DO-213AB surface-mount package. The product's status is Active. Despite ongoing production, alternative models are sometimes necessary for reasons such as procurement flexibility, inventory strategies, or minor parametric differences within tight tolerances allowed for this product category.

Substitute Part Grouping Explanation

Substitute qualification is strictly based on the following allowed parameters: Zener voltage (Vz), maximum power dissipation, maximum impedance (Zzt), reverse leakage current at specified voltage, forward voltage at specified current, operating temperature range, mounting type, component package, and compliance/certification status. Only parts matching these fields within the specified tolerances are considered valid parametric equivalents.

Engineering Selection Recommendations

Both CDLL965A and CDLL965B are active products with non-compliant RoHS status, unaffected by REACH, and classified as ECCN EAR99. Supply chain requirements or tighter voltage tolerance may dictate selection between these models. For applications where ±5% tolerance is required, CDLL965B meets this criterion; for broader tolerance requirements, CDLL965A is suitable. Both parts share identical certification and environmental status fields and mounting formats.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for CDLL965A?
A1: Substitution is permitted when the Zener voltage, power rating, impedance, leakage current, forward voltage, operating temperature, mounting type, and package match or are within specified tolerances.

Q2: Does CDLL965B differ mechanically from CDLL965A?
A2: No. Both are supplied in the DO-213AB MELF surface-mount package.

Q3: Are there compliance differences between CDLL965A and CDLL965B?
A3: Both models are RoHS non-compliant and REACH unaffected, classified under ECCN EAR99 and HTSUS 8541.10.0050.

Q4: When should CDLL965B be chosen as a substitute for CDLL965A?
A4: CDLL965B should be selected when a Zener diode with 15 V nominal voltage, identical mechanical and environmental specifications, and tighter ±5% tolerance is required.

Q5: Are mounting and packaging considerations the same for both parts?
A5: Yes. Both CDLL965A and CDLL965B utilize Surface Mount technology and the DO-213AB, MELF case and device package.
