Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M33ZHA0G is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Nominal Zener voltage (Vz) must be 33 V
• Voltage tolerance must be ±5% or tighter
• Reverse leakage current must not exceed 500 nA @ 25.1 V
• Operating temperature range must encompass the application requirements

Mechanical Compatibility Criteria:

• Package type must be DO-204AC or DO-15 axial through-hole
• Mounting configuration must support through-hole PCB assembly

Regulatory & Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required
• Active product status required

The 1N5364B-TP manufactured by Micro Commercial Co meets all substitution criteria. This part shares identical nominal Zener voltage (33 V), tolerance (±5%), reverse leakage specification (500 nA @ 25.1 V), and package configuration (DO-15 axial). The substitute part is active-status, RoHS3 compliant, and REACH unaffected.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (2M33ZHA0G): The 2M33ZHA0G is the specified component with active product status, AEC-Q101 automotive qualification, and full operational temperature range of -55°C to 175°C. This part is suitable for applications requiring automotive-grade reliability and extended high-temperature operation.

Substitute Part (1N5364B-TP): The 1N5364B-TP is a direct electrical substitute with identical Zener voltage (33 V), tolerance (±5%), and reverse leakage characteristics (500 nA @ 25.1 V). The substitute offers higher power dissipation capability (5 W versus 2 W) and lower impedance (10 Ohms versus 23 Ohms), providing enhanced performance margin in power-limited applications. Both parts are active-status, RoHS3 compliant, and REACH unaffected.

The substitute part operates within -55°C to 150°C, which covers standard industrial and commercial temperature ranges. Applications requiring operation above 150°C must use the primary part (2M33ZHA0G) to ensure compliance with the extended temperature specification.

Frequently Asked Questions (FAQ)

Q: Can the 1N5364B-TP directly replace the 2M33ZHA0G in all applications?

A: The 1N5364B-TP is electrically equivalent for Zener voltage (33 V), tolerance (±5%), and reverse leakage (500 nA @ 25.1 V). Both parts use identical DO-15 axial through-hole packaging. Substitution is valid for applications operating within -55°C to 150°C. Applications requiring operation above 150°C must use the primary part (2M33ZHA0G) to maintain the extended temperature specification of -55°C to 175°C.

Q: What are the differences in power handling between these parts?

A: The 2M33ZHA0G is rated for 2 W maximum power dissipation, while the 1N5364B-TP is rated for 5 W. The substitute part provides higher power dissipation capability. In applications where the 2M33ZHA0G operates near its 2 W limit, the 1N5364B-TP offers additional thermal margin.

Q: Are both parts suitable for automotive applications?

A: The 2M33ZHA0G carries AEC-Q101 automotive qualification. The 1N5364B-TP is active-status and RoHS3 compliant but does not list AEC-Q101 qualification in the provided specifications. Applications requiring automotive-grade qualification must use the primary part (2M33ZHA0G).

Q: Do these parts have identical impedance characteristics?

A: No. The 2M33ZHA0G has maximum impedance (Zzt) of 23 Ohms, while the 1N5364B-TP has maximum impedance of 10 Ohms. Lower impedance in the substitute part results in improved voltage regulation and reduced dynamic resistance. This difference is beneficial in most applications but must be evaluated for circuits with specific impedance requirements.

Q: Are both parts available in the same packaging?

A: Both parts use DO-15 axial through-hole packaging. The 2M33ZHA0G is supplied as DO-204AC (DO-15), and the 1N5364B-TP is supplied as DO-15. These packages are mechanically and electrically compatible for through-hole PCB assembly.

Q: What compliance certifications apply to both parts?

A: Both the 2M33ZHA0G and 1N5364B-TP are RoHS3 compliant and REACH unaffected. The 2M33ZHA0G additionally carries AEC-Q101 automotive qualification. Both parts have Moisture Sensitivity Level (MSL) of 1 (Unlimited).
