2M33Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 2M33Z is an active-status Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 33 V nominal Zener voltage and 2 W maximum power dissipation. This component is packaged in DO-204AC (DO-15) axial through-hole configuration and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist, enabling component selection flexibility for circuit design and procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2M33Z are identified based on the following critical parameters:

Electrical Compatibility Criteria:

• Zener voltage (Nom): 33 V
• Voltage tolerance: ±5%
• Reverse leakage current: 500 nA @ 25.1 V
• Mounting type: Through Hole

Mechanical Compatibility Criteria:

• Package / Case: DO-204AC, DO-15, Axial
• Lead configuration: Axial through-hole

Regulatory & Compliance Criteria:

• RoHS3 Compliant status
• REACH Unaffected status
• ECCN: EAR99

The 1N5364B-TP meets all electrical and mechanical compatibility requirements. While this substitute exhibits higher maximum power rating (5 W versus 2 W) and lower impedance (10 Ohms versus 23 Ohms), these parameters represent enhanced performance characteristics that do not preclude substitution in applications designed for the 2M33Z specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (2M33Z): The 2M33Z is the specified component for applications requiring 33 V Zener regulation at 2 W maximum power dissipation. This part is active-status with full ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute Selection (1N5364B-TP): The 1N5364B-TP is a direct electrical and mechanical substitute for the 2M33Z. Both components share identical Zener voltage (33 V), voltage tolerance (±5%), reverse leakage current (500 nA @ 25.1 V), and axial through-hole package configuration. The 1N5364B-TP maintains active product status and ROHS3 compliance. The substitute exhibits superior power handling (5 W versus 2 W) and lower impedance (10 Ohms versus 23 Ohms), characteristics that enhance performance in regulation applications without introducing incompatibility.

The operating temperature range of the 1N5364B-TP (-55°C to 150°C) is narrower than the 2M33Z (-55°C to 175°C). Applications requiring operation above 150°C junction temperature require the primary 2M33Z specification.

Frequently Asked Questions (FAQ)

Q: Can the 1N5364B-TP replace the 2M33Z in all applications?

A: The 1N5364B-TP is electrically and mechanically compatible with the 2M33Z for applications operating within the temperature range of -55°C to 150°C. Applications requiring junction temperatures above 150°C require the 2M33Z, which is rated to 175°C.

Q: What is the significance of the different power ratings (2 W versus 5 W)?

A: The 1N5364B-TP has a higher maximum power dissipation rating (5 W) compared to the 2M33Z (2 W). This represents enhanced thermal capability and does not create substitution barriers. Applications designed for 2 W operation function within the 5 W capability of the substitute.

Q: Are the packaging and lead configurations identical?

A: Both the 2M33Z and 1N5364B-TP use DO-204AC (DO-15) axial through-hole packaging. Physical dimensions and lead spacing are compatible for direct board-level substitution.

Q: Do both parts meet the same regulatory requirements?

A: Both the 2M33Z and 1N5364B-TP are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Regulatory compliance is equivalent.

Q: What is the difference in impedance between these parts?

A: The 2M33Z has a maximum impedance of 23 Ohms, while the 1N5364B-TP has a maximum impedance of 10 Ohms. Lower impedance in the substitute results in improved voltage regulation characteristics and reduced dynamic resistance.

Q: Are there inventory considerations for component selection?

A: The 2M33Z has 1,070 pieces in stock. The 1N5364B-TP has 9,897 pieces in stock. Availability may influence procurement decisions based on project timeline requirements.
