GDZT2R6.8 Equivalent & Substitute Parts Reference

Part Overview

The GDZT2R6.8, manufactured by Rohm Semiconductor, is a Zener diode rated at 6.8 V nominal Zener voltage, 100 mW maximum power dissipation, and ±5% tolerance, in a surface mount GMD2 (0201/0603 metric) package. Its product status is listed as obsolete. Identifying suitable equivalent or substitute parts is essential to maintain design continuity and supply chain reliability when the original device is no longer available.

Substitute Part Grouping Explanation

Substitutes for the GDZT2R6.8 Zener diode are strictly determined based on the following common parameters:

Nominal Zener Voltage (Vz): 6.8 V
Tolerance
Maximum Power Dissipation
Maximum Reverse Leakage Current at Specified Reverse Voltage
Surface Mount Package format matching 0603 metric
RoHS and REACH compliance
Moisture Sensitivity Level (MSL)
Same diode category and mounting type

Only parts that fully match or tighten these criteria are included in the substitute group.

Engineering Selection Recommendations

When selecting substitutes for the GDZT2R6.8 Zener diode, preference should be given to parts matching the RoHS3 compliant status, MSL 1 (unlimited), and REACH unaffected certifications. All substitute parts listed, including SDZT15R6.8 and ADZT15R6.8B, conform to these compliance requirements and have active product status, supporting regulatory and continuous supply needs.

Frequently Asked Questions (FAQ)

What are the critical parameters for selecting a substitute for GDZT2R6.8?

Substitution must be based on nominal Zener voltage, tolerance, maximum power dissipation, reverse leakage current at specified test voltage, surface mount package compatibility, and regulatory compliance (RoHS, REACH, MSL).

Are all substitute parts matched for package and mounting type?

Yes, all listed substitutes use surface mount 0603 metric-compatible packages.

Can a tighter tolerance substitute (e.g., ±2.54%) be used in place of ±5%?

Yes, parts with a tighter tolerance are eligible substitutes under the specified rules.

Do substitute parts have different compliance statuses?

No, all parts listed are ROHS3 Compliant, MSL 1, and REACH Unaffected per input data.

Is the maximum operating temperature higher for substitutes?

Based on the provided parameters, SDZT15R6.8 and ADZT15R6.8B specify an operating temperature up to 150°C.

Are the electrical characteristics, such as maximum Zener voltage and reverse leakage, identical in the substitutes?

Yes, the listed substitutes all match 6.8 V nominal Zener voltage, 100 mW power, and 500 nA maximum reverse leakage at 3.5 V.
