Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based on an exact match to the following critical parameters, which determine interchangeability for Zener diodes in this category:

• Voltage - Zener (Nom) (Vz)
• Tolerance
• Power - Max
• Impedance (Max) (Zzt)
• Operating Temperature
• Mounting Type
• Package / Case
• Product Status

The substitute part JANTX1N4103UR-1 replicates all specified parameters relevant for functional and mechanical replacement.

Parameter Comparison

Engineering Selection Recommendations

Both CDLL4771 and JANTX1N4103UR-1 are active status parts with matching compliance references: RoHS non-compliant and REACH Unaffected. Both are listed under ECCN EAR99 and HTSUS 8541.10.0050. Selection can therefore be based directly on product status and regulatory alignment per these criteria.
