Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2EZ39D5-TP is determined by the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Zener voltage (Nominal): 39 V
• Tolerance: ±5%
• Package / Case: DO-41 (axial through-hole)
• Mounting Type: Through Hole

Secondary Compatibility Factors:

• Voltage - Forward (Vf) @ If: 1.2 V @ 200 mA
• Operating Temperature Range
• RoHS and REACH compliance status
• ECCN and HTSUS classification

The 1N4754A from Lumimax Optoelectronic Technology meets the primary matching criteria with identical nominal Zener voltage (39 V), tolerance (±5%), and DO-41 package configuration. Both components are Active products with equivalent regulatory compliance. Differences in maximum power rating (2 W vs. 1 W) and impedance characteristics must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

2EZ39D5-TP (Micro Commercial Co): This component is the primary specification. It delivers 2 W maximum power dissipation with 30 Ohms maximum impedance. The device operates across -55°C to 150°C and maintains RoHS3 compliance. Current inventory status shows 1,138 pieces in stock. This part is suitable for applications requiring higher power handling and lower impedance characteristics.

1N4754A (Lumimax Optoelectronic Technology): This substitute part provides identical Zener voltage (39 V) and tolerance (±5%) in the same DO-41 package. The 1N4754A is rated for 1 W maximum power with 60 Ohms maximum impedance. It operates across an extended temperature range (-65°C to 200°C) and maintains RoHS compliance. Current inventory shows 5,990 pieces available. This part is suitable for applications with lower power requirements and extended temperature operation. The higher reverse leakage current (5 µA vs. 500 nA) must be considered in precision voltage reference applications.

Both components share identical forward voltage characteristics (1.2 V @ 200 mA), equivalent regulatory classification (EAR99, HTSUS 8541.10.0050), and Active product status. Selection between these parts depends on application power dissipation requirements, impedance tolerance, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1N4754A directly replace the 2EZ39D5-TP in all applications?

A: Direct substitution is limited by power rating differences. The 1N4754A is rated for 1 W maximum power, while the 2EZ39D5-TP is rated for 2 W. Applications requiring power dissipation above 1 W must use the 2EZ39D5-TP. For applications operating at or below 1 W, the 1N4754A is mechanically and electrically compatible.

Q: Are there package compatibility concerns between these parts?

A: Both components use the DO-41 axial through-hole package. Mechanical compatibility is confirmed. PCB layout and lead spacing are identical, allowing direct board-level substitution without design modification.

Q: How do the impedance specifications affect substitution?

A: The 2EZ39D5-TP has 30 Ohms maximum impedance, while the 1N4754A has 60 Ohms maximum impedance. Lower impedance provides better voltage regulation and faster transient response. Applications sensitive to impedance characteristics must use the 2EZ39D5-TP.

Q: What is the significance of the reverse leakage current difference?

A: The 2EZ39D5-TP specifies 500 nA reverse leakage at 29.7 V, while the 1N4754A specifies 5 µA at the same voltage. The lower leakage of the 2EZ39D5-TP is advantageous in precision voltage reference and low-current bias applications. The 1N4754A is acceptable for general-purpose regulation applications.

Q: Do both parts meet the same regulatory requirements?

A: Both components are classified as EAR99 and share the same HTSUS code (8541.10.0050). The 2EZ39D5-TP is RoHS3 compliant, while the 1N4754A is RoHS compliant. Both are REACH Unaffected. Regulatory compliance is equivalent for most applications.

Q: What is the operating temperature consideration for substitution?

A: The 2EZ39D5-TP operates from -55°C to 150°C. The 1N4754A operates from -65°C to 200°C, providing extended low-temperature and high-temperature capability. For applications exceeding 150°C, the 1N4754A is required. For applications below -55°C, the 1N4754A is required.
