Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDZT2R8.2B are selected based on exact or matching key parameters within the Zener diode product category. Allowed substitution is based strictly on:

• Zener voltage (8.2 V)
• Power rating (100 mW)
• Maximum impedance (30 Ohms)
• Maximum reverse leakage current (500 nA @ 5 V)
• Package/case (2-SMD, Flat Lead) and supplier device package (VMN2/SOD-923)
• Compliance (RoHS3, REACH)
• Moisture sensitivity (MSL 1)
• Mounting type (Surface Mount)
• Operating temperature

Substitutes may originate from the same manufacturer and must conform precisely to these parameters as provided.

Parameter Comparison

Engineering Selection Recommendations

Selection among available substitute Zener diodes should be based on product status and compliance certifications. The CDZT2R8.2B is listed as "Not For New Designs," while both CDZVT2R8.2B and CDZT2RA8.2B are active and meet the same compliance standards (ROHS3 Compliant, REACH Unaffected, MSL 1). These active parts are suitable for designs requiring continued manufacturer support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: What determines if a Zener diode can be substituted for CDZT2R8.2B?
A: The substitute must have matching Zener voltage, power rating, maximum impedance, reverse leakage current, mounting type, package/case, compliance (RoHS, REACH), moisture sensitivity, and operating temperature range.

Q: Is the package for all listed substitute parts the same as CDZT2R8.2B?
A: All substitute parts use a 2-SMD, Flat Lead package in the SOD-923 family, ensuring mechanical compatibility for surface-mount installation.

Q: Are there any changes in electrical characteristics among these substitutes?
A: According to the provided data, all substitutes match the key parameters including Zener voltage, power, impedance, and leakage current, with minor differences in specified tolerance documentation.

Q: Do substitute parts meet RoHS and REACH compliance like the original part?
A: All substitute parts are ROHS3 Compliant and REACH Unaffected, meeting the same regulatory standards as CDZT2R8.2B.

Q: Why is product status important when choosing a substitute?
A: Only active status parts are recommended for new or ongoing designs to ensure availability and long-term manufacturer support, since CDZT2R8.2B is not recommended for new designs.
