Substitute Part Grouping Explanation

Substitution of the obsolete CZ5388B TR is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Zener (Nom): 200 V
• Power - Max: 5 W
• Tolerance: ±5%
• Impedance (Max): 480 Ohms
• Current - Reverse Leakage @ Vr: 500 nA @ 152 V
• Voltage - Forward (Max) @ If: 1.2 V @ 1 A
• Operating Temperature Range: -65°C to 200°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: Axial configuration

The substitute part 1N5388BRLG from onsemi meets all specified electrical parameters and maintains axial through-hole mounting compatibility. The primary distinction is product status: the substitute is active production, whereas the original is obsolete.
