Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMB2EZ16D5-TP is determined by the following critical parameters:

Primary Substitution Criteria:

• Zener voltage (Vz): 16 V nominal
• Tolerance: ±5%
• Package / Case: DO-214AA (SMB) surface mount
• Operating temperature range: -55°C to 150°C
• RoHS3 compliance

Secondary Compatibility Factors:

• Power rating: Minimum 2 W (higher ratings are acceptable for drop-in replacement)
• Impedance (Zzt): Maximum 8 Ohms (higher impedance values acceptable within circuit tolerance)
• Reverse leakage current: Maximum 500 nA @ 12.2 V (higher leakage acceptable within application requirements)
• Forward voltage: Maximum 1.5 V @ 200 mA

Substitute parts meeting all primary criteria and maintaining compatibility with secondary factors are classified as direct equivalents or functional substitutes.

Engineering Selection Recommendations

1SMB2EZ16_R1_00001 (Panjit International Inc.)

This part is a parametric equivalent to the SMB2EZ16D5-TP. It matches all critical electrical specifications: 16 V nominal Zener voltage, ±5% tolerance, 2 W maximum power, 8 Ohms maximum impedance, and 500 nA reverse leakage current. The operating temperature range (-55°C to 150°C) and DO-214AA (SMB) package are identical. This part carries active product status and ROHS3 compliance with unlimited moisture sensitivity level (MSL 1). This substitute is suitable for direct replacement in applications where the original part is no longer available.

3SMBJ5930B-TP (Micro Commercial Co)

This part is a functional substitute with higher power rating (3 W versus 2 W). It maintains the same 16 V nominal Zener voltage, ±5% tolerance, and DO-214AA (SMB) package. The impedance is 10 Ohms (versus 8 Ohms) and reverse leakage is 1 µA (versus 500 nA). This part carries active product status and ROHS3 compliance. The increased power rating and slightly higher impedance and leakage current are acceptable for applications where the original 2 W specification is not a limiting constraint. This substitute provides enhanced thermal performance due to higher power dissipation capability.

Both substitutes are ROHS3 compliant and available in active product status, ensuring long-term supply chain viability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 3SMBJ5930B-TP (3 W) be used in place of the SMB2EZ16D5-TP (2 W)?

A: Yes. The 3SMBJ5930B-TP is a functional substitute. Both parts share identical Zener voltage (16 V), tolerance (±5%), and package (DO-214AA/SMB). The higher power rating (3 W) does not prevent operation in circuits designed for 2 W. The slightly higher impedance (10 Ohms versus 8 Ohms) and reverse leakage (1 µA versus 500 nA) remain within acceptable ranges for most applications. Verify circuit requirements do not mandate the lower impedance or leakage specifications.

Q: Is the 1SMB2EZ16_R1_00001 a direct replacement?

A: Yes. The 1SMB2EZ16_R1_00001 is a parametric equivalent. It matches all electrical specifications of the SMB2EZ16D5-TP: 16 V Zener voltage, ±5% tolerance, 2 W power rating, 8 Ohms impedance, and 500 nA reverse leakage. The only difference is the manufacturer (Panjit International Inc. versus Micro Commercial Co). Both parts use the same DO-214AA (SMB) package and operate across -55°C to 150°C.

Q: Why is the SMB2EZ16D5-TP listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by the original supplier. The substitute parts listed (1SMB2EZ16_R1_00001 and 3SMBJ5930B-TP) carry active product status, ensuring continued availability and supply chain support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both substitute parts (1SMB2EZ16_R1_00001 and 3SMBJ5930B-TP) are ROHS3 compliant, matching the compliance status of the original SMB2EZ16D5-TP.

Q: What is the difference between the two substitute parts?

A: The 1SMB2EZ16_R1_00001 is a parametric equivalent with identical 2 W power rating and 8 Ohms impedance. The 3SMBJ5930B-TP offers higher power dissipation (3 W) and slightly higher impedance (10 Ohms) and reverse leakage. Select the 1SMB2EZ16_R1_00001 for exact electrical matching; select the 3SMBJ5930B-TP for applications requiring enhanced thermal performance.

Q: Can these parts be used interchangeably in the same circuit board layout?

A: Yes. All three parts use the DO-214AA (SMB) surface mount package with identical pinout and footprint. No PCB layout modifications are required when substituting between these parts.

Q: What certifications apply to these substitute parts?

A: Both substitute parts are ROHS3 compliant. The 1SMB2EZ16_R1_00001 carries REACH Unaffected status and MSL 1 (Unlimited). The 3SMBJ5930B-TP carries REACH Unaffected status and MSL 1 (Unlimited). Both parts are classified under ECCN EAR99 and HTSUS 8541.10.0050.
