Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2M47Z B0G is permissible when the alternative component maintains the following critical parameters:

Mandatory Matching Criteria:

• Zener voltage nominal value: 47 V
• Voltage tolerance: ±5%
• Mounting type: Through Hole
• Package classification: DO-15 / DO-204AC axial configuration
• Reverse leakage current: 500 nA @ 35.8 V
• RoHS3 compliance status
• REACH unaffected classification

Allowable Variations:

• Power rating: Equal to or greater than 2 W
• Impedance (maximum): Equal to or less than 40 Ohms
• Operating temperature range: Minimum -55°C to maximum ≥150°C
• Manufacturer: Different manufacturer acceptable if all above criteria met

The 1N5368B-TP from Micro Commercial Co qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

Primary Part: 2M47Z B0G

Selection is appropriate for applications requiring the full operating temperature range of -55°C to 175°C. This component maintains Active product status with established supply chain availability (925 units in stock). RoHS3 compliance and REACH unaffected status confirm regulatory alignment for industrial and commercial applications.

Substitute Part: 1N5368B-TP

The 1N5368B-TP provides functional equivalence with enhanced power dissipation capability (5 W versus 2 W) and improved impedance characteristics (25 Ohms maximum versus 40 Ohms maximum). This substitute is suitable for applications where the operating temperature does not exceed 150°C. The substitute maintains identical zener voltage, tolerance, reverse leakage specifications, and regulatory compliance. Higher inventory availability (4335 units in stock) supports supply chain continuity. The substitute is compatible with existing through-hole PCB layouts designed for DO-15 axial packages.

Frequently Asked Questions (FAQ)

Q: Can the 1N5368B-TP replace the 2M47Z B0G in all applications?

A: The 1N5368B-TP is functionally equivalent for applications operating at or below 150°C. If your circuit operates above 150°C and below 175°C, the 2M47Z B0G is required. Both components maintain identical zener voltage (47 V), tolerance (±5%), and reverse leakage characteristics.

Q: What is the significance of the higher power rating on the 1N5368B-TP?

A: The 1N5368B-TP is rated for 5 W maximum power dissipation compared to 2 W for the 2M47Z B0G. This higher rating provides additional thermal margin in applications with sustained current flow through the zener diode. The substitute will operate cooler under identical load conditions.

Q: Are there physical differences between these components?

A: Both components use the DO-15 axial through-hole package configuration. Physical dimensions and lead spacing are compatible. PCB layouts designed for either component are interchangeable.

Q: How do the impedance specifications affect circuit performance?

A: The 1N5368B-TP impedance maximum of 25 Ohms is superior to the 2M47Z B0G specification of 40 Ohms. Lower impedance results in improved voltage regulation stability and reduced output impedance in voltage reference applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2M47Z B0G and 1N5368B-TP are RoHS3 compliant with REACH unaffected status, confirming suitability for regulated markets and applications requiring environmental compliance documentation.

Q: What is the reverse leakage current specification and why is it identical?

A: Both components specify 500 nA maximum reverse leakage current measured at 35.8 V. This parameter defines the quality of the PN junction and is critical for precision voltage reference applications. Identical specifications ensure equivalent performance in low-current bias circuits.
