CDZT2RA7.5B Equivalent & Substitute Parts Reference

Part Overview

The CDZT2RA7.5B from Rohm Semiconductor is a Zener diode with a nominal Zener voltage of 7.5 V, maximum power rating of 100 mW, and a tolerance of ±2%. Packaged in a surface-mount VMN2 (SOD-923) case, this diode features a reverse leakage current of 500 nA at 4 V and a maximum impedance of 30 Ohms. The part is currently active, RoHS3 compliant, and available in inventory. Alternative models are necessary for design flexibility, supply chain risk mitigation, and to ensure manufacturing continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching or exceeding electrical and compliance parameters critical for Zener diode applications. Only parts with the following parameters equivalent to or better than the main part are considered suitable substitutes:

• Zener voltage: 7.5 V
• Power rating: ≥ 100 mW
• Tolerance: ±2% (where specified)
• Impedance: ≤ 30 Ohms
• Reverse leakage current: ≤ 500 nA @ 4 V (where test conditions are equivalent)
• Surface Mount package form factor and package compatibility
• Temperature rating up to 150°C (minimum)
• Environmental and regulatory status: RoHS3 Compliant, REACH Unaffected, MSL 1

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed (CDZVT2R7.5B and BZT585B7V5T-7) are active status, RoHS3 Compliant, have MSL 1 (Unlimited) ratings, and are REACH Unaffected. These regulatory and compliance certificates directly support their use as substitutes for the CDZT2RA7.5B in applications where product status and environmental compliance must be maintained.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical for substituting the CDZT2RA7.5B Zener diode?
A1: Zener voltage, tolerance, power rating, maximum impedance, reverse leakage current, operating temperature, mounting type, and package compatibility are critical parameters.

Q2: Is package compatibility mandatory for substitution?
A2: Yes, substitute Zener diodes must use a compatible surface-mount package (e.g., VMN2/SOD-923, SOD-523) to ensure proper fit and function in the PCB footprint.

Q3: How does RoHS and REACH status affect selection?
A3: Substitute parts must match the RoHS and REACH environmental compliance of the original CDZT2RA7.5B for regulatory and supply chain requirements.

Q4: Can substitute Zener diodes with higher power ratings be used?
A4: Diodes with the same or higher power ratings as the original are included if other key parameters are met.

Q5: Is it necessary to consider differences in test conditions for reverse leakage or other parameters?
A5: Only provided parameter values and test conditions are considered; substitute selection is based strictly on supplied data.
