CDLL5535B/TR Equivalent & Substitute Parts Reference

Part Overview

The CDLL5535B/TR from Microchip Technology is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 15 V and a maximum power dissipation of 500 mW, housed in a surface-mount DO-213AA package. The product is classified as active and available in tape and reel packaging. Identifying alternative models is required for inventory flexibility, procurement continuity, and compliance considerations, especially when evaluating stock levels or seeking parametric or regulatory alternatives.

Substitute Part Grouping Explanation

Substitute Zener diode parts are grouped strictly on matching key parameters: Zener voltage (15 V), power dissipation (500 mW), maximum impedance, reverse leakage current, forward voltage at specified current, operating temperature range, surface mount package type (DO-213AA), and product status. Only those parts meeting these specific parameters are considered suitable substitutes.
