Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based on strict equivalence in key electrical and mechanical characteristics:

• Nominal Zener voltage (100 V)
• Tolerance (±5%)
• Package type and mounting (DO-214AA, SMB, surface mount)
• Operating temperature range (-65°C ~ 150°C)
• Compliance and product status parameters

These factors ensure form, fit, and function equivalence within the Zener diode category for engineering substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

Both SMBJ4764A/TR13 and SZ1SMB5949BT3G are active Zener diodes in the DO-214AA/SMB package with identical nominal voltage and tolerance. The SZ1SMB5949BT3G is ROHS3 Compliant, whereas SMBJ4764A/TR13 is RoHS non-compliant. Both parts have an MSL of 1 (Unlimited) and are listed as REACH Unaffected. Certification status and product activity should guide selection when specific regulatory requirements are present.
