CDLL5242 Equivalent & Substitute Parts Reference

Part Overview

The Microchip Technology CDLL5242 is a Zener diode categorized under Diodes, Zener, specified for a nominal voltage of 12 V, ±20% tolerance, and realized in a DO-213AB surface-mount package. The product is currently active and available as new original stock. Alternative models may be necessary to address stock availability, tolerance requirements, or compliance with specific application criteria. Proper substitution ensures electrical and mechanical compatibility within the same product category and package constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution is evaluated strictly by matching the following key parameters: Zener voltage—nominal (Vz), tolerance, impedance (Zzt), reverse leakage current, forward voltage, operating temperature range, mounting type, and package/case. All listed substitutes retain package compatibility (DO-213AB, MELF), mounting method (Surface Mount), and functional type (Zener diode). Substitutes are grouped based on parametric equivalence without deviation from specified electrical and mechanical figures.

Key parameters considered for substitute grouping:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Impedance (Max) (Zzt)
• Current - Reverse Leakage @ Vr
• Voltage - Forward (Vf) (Max) @ If
• Operating Temperature
• Mounting Type
• Package / Case

Parameter Comparison

Engineering Selection Recommendations

Both CDLL5242 and parametric equivalent CDLL5242B are active and stocked, featuring RoHS non-compliance and REACH unaffected status. Both comply with ECCN EAR99 and share an identical HTSUS code. Selection between these models is based on tolerance requirements alone: CDLL5242 provides ±20%, while CDLL5242B offers ±5%. No other distinction exists in terms of packaging, mounting, or fundamental electrical parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria must be matched to substitute CDLL5242 in the Diodes, Zener category?
A1: Substitution requires matching Zener voltage (12 V), impedance, reverse leakage current, forward voltage, operating temperature, mounting type (surface mount), and identical package (DO-213AB, MELF).

Q2: Are CDLL5242 and CDLL5242B mechanically interchangeable in circuit board placement?
A2: Yes. Both use the DO-213AB, MELF package for surface mount applications, ensuring identical mechanical compatibility.

Q3: Does tolerance difference affect substitution?
A3: Tolerance must match application requirements. CDLL5242 implements ±20% tolerance; CDLL5242B delivers ±5%. All other electrical and physical specifications remain equivalent.

Q4: Are there differences in regulatory compliance?
A4: Both parts are RoHS non-compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.10.0050.

Q5: Can these substitutes be used interchangeably for inventory management?
A5: Both are active and available, and may be substituted strictly when the tolerance specification is suitable for the end application.
