CDLL965BE3 Equivalent & Substitute Parts

Part Overview

The CDLL965BE3 is a Zener diode voltage regulator manufactured by Microchip Technology, designed for surface mount applications in DO-213AA packaging. This component operates at a nominal Zener voltage of 15 V with a maximum power dissipation of 500 mW, suitable for voltage regulation and protection circuits. The part is currently Active in product status with 895 pieces available in new original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, application-specific certifications, or packaging preferences.

Substitute Part Grouping Explanation

Substitution of the CDLL965BE3 is determined by strict equivalence across the following critical parameters:

Zener Voltage (Vz): 15 V nominal with ±5% tolerance
Power Dissipation: 500 mW maximum
Impedance (Zzt): 16 Ohms maximum
Reverse Leakage Current: 500 nA @ 11 V
Forward Voltage: 1.1 V maximum @ 200 mA
Operating Temperature Range: -65°C to 175°C
Package Type: DO-213AA surface mount

The substitute part JANTX1N965BUR-1 meets all electrical parameters identically. Substitution is valid when these parameters are matched across both components. Differences in product grade, qualification standards, RoHS compliance, and inventory availability do not affect electrical or mechanical interchangeability.

Engineering Selection Recommendations

CDLL965BE3 is the primary selection for applications requiring RoHS3 compliance. This part carries ROHS3 Compliant status and is suitable for commercial and industrial applications with environmental compliance requirements. Current inventory of 895 pieces supports standard production volumes.

JANTX1N965BUR-1 is the appropriate selection for military and aerospace applications. This part carries Military grade qualification to MIL-PRF-19500/117 standard, with Moisture Sensitivity Level (MSL) 1 (Unlimited). The higher inventory level of 15,645 pieces provides extended availability. This part is RoHS non-compliant and is designated for applications where military qualification supersedes commercial environmental standards.

Both parts are electrically and mechanically identical. Selection between them is determined by application requirements: commercial/industrial environments favor CDLL965BE3, while military/aerospace environments require JANTX1N965BUR-1.

Frequently Asked Questions (FAQ)

Q: Can JANTX1N965BUR-1 be used as a direct replacement for CDLL965BE3 in commercial applications?

A: Yes. All electrical parameters, mechanical dimensions, and operating characteristics are identical. The primary difference is military qualification and RoHS compliance status. Commercial applications may use either part provided compliance requirements are met.

Q: What is the significance of the Military grade designation on JANTX1N965BUR-1?

A: Military grade indicates qualification to MIL-PRF-19500/117 standard, which specifies enhanced testing, screening, and reliability requirements. This designation is required for military and aerospace applications but is not necessary for commercial or industrial use.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both parts use DO-213AA surface mount packaging with identical physical dimensions and pin configuration. No PCB layout modifications are required when substituting between these parts.

Q: What does RoHS3 Compliant mean for CDLL965BE3?

A: RoHS3 Compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. This is required for commercial products sold in regulated markets. JANTX1N965BUR-1 is RoHS non-compliant and is not subject to these restrictions due to its military designation.

Q: Can CDLL965BE3 be used in applications requiring MIL-PRF-19500/117 qualification?

A: No. CDLL965BE3 does not carry military qualification. Applications requiring MIL-PRF-19500/117 certification must use JANTX1N965BUR-1.

Q: Are the electrical characteristics identical between both parts?

A: Yes. Zener voltage, power dissipation, impedance, leakage current, forward voltage, and operating temperature range are identical across both parts.
