Substitute Part Grouping Explanation

Substitution of the EDZFHTE619.1B is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Mounting Type: Surface Mount (required match)
• Category: Diodes, Zener (required match)
• Manufacturer: Rohm Semiconductor (preferred continuity)
• RoHS Compliance: ROHS3 Compliant (required match)
• Moisture Sensitivity Level: 1 (Unlimited) (required match)
• ECCN Classification: EAR99 (required match)

Secondary Compatibility Factors:

• Power Rating: Substitute must equal or exceed 100 mW
• Operating Temperature Range: Substitute must support the required thermal envelope
• Package Type: Surface mount package compatibility with assembly equipment

The EDZVFHT2R9.1B qualifies as a substitute based on these parameters. It maintains surface mount configuration, Rohm Semiconductor manufacturing, ROHS3 compliance, MSL 1 rating, and EAR99 classification. The substitute provides enhanced power capability (150 mW versus 100 mW) and extended maximum junction temperature rating (150°C), offering improved thermal performance margins.
