Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CZ5335B TR is based on electrical parameter equivalence and mechanical compatibility within the through-hole axial diode category. The substitute part 1N5335BRLG maintains identical electrical specifications across all critical parameters: nominal Zener voltage of 3.9 V, ±5% tolerance, 5 W maximum power rating, 2 Ohms maximum impedance, 50 µA reverse leakage current at 1 V, and 1.2 V maximum forward voltage at 1 A. Both components operate across the same temperature range of -65°C to 200°C and utilize through-hole axial mounting configuration.

The substitution logic is based on the following key parameters:

• Voltage - Zener (Nom): 3.9 V (exact match)
• Tolerance: ±5% (exact match)
• Power - Max: 5 W (exact match)
• Impedance (Max): 2 Ohms (exact match)
• Current - Reverse Leakage @ Vr: 50 µA @ 1 V (exact match)
• Voltage - Forward (Vf) (Max) @ If: 1.2 V @ 1 A (exact match)
• Operating Temperature: -65°C to 200°C (exact match)
• Mounting Type: Through Hole (exact match)
• Package / Case: Axial (exact match)

Parameter Comparison

Engineering Selection Recommendations

The 1N5335BRLG manufactured by onsemi is a direct electrical and mechanical substitute for the obsolete CZ5335B TR. All electrical parameters match exactly, and both components utilize through-hole axial packaging suitable for identical PCB mounting configurations.

Selection of the 1N5335BRLG eliminates obsolescence risk while maintaining complete functional equivalence in voltage regulation and transient protection applications requiring 3.9 V, 5 W Zener diode performance.

Frequently Asked Questions (FAQ)

Q: Can the 1N5335BRLG directly replace the CZ5335B TR in existing designs?

A: Yes. The 1N5335BRLG is electrically and mechanically equivalent. All electrical parameters are identical, and both components use through-hole axial mounting. No circuit modifications are required.

Q: What is the difference between DO-201AA and T-18 axial packages?

A: Both are through-hole axial diode packages. DO-201AA and T-18 are equivalent designations for the same physical form factor used in axial-lead component mounting. The 1N5335BRLG in T-18 axial package is mechanically compatible with DO-201AA footprints.

Q: Why is the CZ5335B TR listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The 1N5335BRLG provides continued access to equivalent 3.9 V, 5 W Zener diode functionality from an active manufacturer.

Q: Are there any compliance differences between the two parts?

A: The 1N5335BRLG is ROHS3 compliant and REACH unaffected. The CZ5335B TR compliance status is not specified in available documentation. For applications requiring specific environmental compliance, the 1N5335BRLG meets current regulatory standards.

Q: What is the inventory status of these parts?

A: The CZ5335B TR has 798 pieces in stock as new original inventory. The 1N5335BRLG has 1402 pieces in stock as new original inventory, providing greater availability for procurement.

Q: Can the 1N5335BRLG be used in high-temperature applications?

A: Yes. The 1N5335BRLG operates across the full temperature range of -65°C to 200°C, identical to the CZ5335B TR, supporting applications requiring extended temperature performance.
