Equivalent & Substitute Parts for CDLL753

Part Overview

The CDLL753 is a Zener Diode manufactured by Microchip Technology, categorized under Diodes, Zener. It features a nominal Zener voltage of 6.2 V, maximum power dissipation of 500 mW, and is supplied in a DO-213AB surface-mount package. It operates over a wide temperature range (-65°C to 175°C) and provides a reverse leakage current of 5 µA at 3.5 V. The device is currently active but is RoHS non-compliant. Identifying alternative models is necessary in scenarios where tighter parameter tolerances, extended compliance, or additional certification requirements are present.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching electrical and mechanical parameters. The allowed parameters include the following: nominal Zener voltage, tolerance, maximum power dissipation, maximum impedance, reverse leakage current, maximum forward voltage at specified current, operating temperature range, mounting type, and physical package. Substitute parts are grouped if all these parameters are identical or within specified bounds. Packaging, RoHS status, and regulatory compliance are considered for selection when sourcing or environmental requirements are a factor.

Parameter Comparison

Engineering Selection Recommendations

Both CDLL753 and CDLL753A are active, RoHS non-compliant, with REACH unaffected status, and have ECCN EAR99 and HTSUS 8541.10.0050. With identical electrical and mechanical parameters, the only difference is a tighter tolerance in CDLL753A. Selection is determined by stock availability, required tolerance level, and compliance needs as per the specified parameters.

Frequently Asked Questions (FAQ)

Q1: What defines a valid substitute for CDLL753?
A valid substitute must match nominal Zener voltage, maximum power rating, impedance, reverse leakage current, forward voltage at specified current, operating temperature, mounting type, and package/case type. Regulatory and compliance status may also be considered.

Q2: Is CDLL753A fully compatible as a substitute?
CDLL753A matches all specified electrical and mechanical key parameters of CDLL753, with a tighter tolerance (±5% vs. ±10%), making it suitable as a direct substitute within these parameters.

Q3: Are there any package or mounting differences between substitutes?
CDLL753 and CDLL753A both use the DO-213AB, MELF package, and are designed for surface-mount applications. No differences exist in mounting or package.

Q4: Do both parts share the same compliance and certification characteristics?
Both CDLL753 and CDLL753A are RoHS non-compliant, REACH unaffected, and share ECCN EAR99 and HTSUS 8541.10.0050 status. Moisture Sensitivity Level is 1 (Unlimited).

Q5: What should be considered for engineering selection between these two parts?
Selection depends on preferred parameter tolerance and required stock. Both parts are equivalent for all other electrical and mechanical parameters.
