Key Parameters

Substitute Part Grouping Explanation

Substitute grouping is based strictly on the following key parameters that define electrical and mechanical compatibility for Zener diodes in the DO-214AA, SMB category:

• Zener Voltage (Vz)
• Tolerance
• Power Rating
• Impedance (Max)
• Reverse Leakage Current @ Vr
• Forward Voltage (Vf) @ If
• Operating Temperature Range
• Mounting Type
• Package / Case

Other criteria such as product status, RoHS compliance, and inventory levels are included for selection based on regulatory or availability requirements. Only parts that match the surface-mount DO-214AA (SMB) form factor and provided electrical parameters are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between SMBJ5932C/TR13 and substitute 1SMB5932B-13 must be based on product status (active), regulatory compliance, and inventory levels. The main part SMBJ5932C/TR13 is RoHS non-compliant, while the substitute 1SMB5932B-13 is ROHS3 compliant. Both components have REACH unaffected status and identical Moisture Sensitivity Levels (MSL 1). ECCN and HTSUS classifications match. Consider compliance compatibility for environmental and regulatory requirements. Inventory availability is greater for 1SMB5932B-13.

Frequently Asked Questions (FAQ)

Q: What are the primary parameters that determine the suitability of an equivalent Zener diode in this category?
A: Substitution suitability is strictly determined by Zener voltage, tolerance, power rating, impedance, leakage current, forward voltage, operating temperature range, mounting type, and package/case.

Q: What packaging and mounting considerations must be observed when choosing substitutes?
A: Only surface-mount DO-214AA (SMB) package types are considered for mechanical equivalence. Both SMBJ5932C/TR13 and 1SMB5932B-13 meet these requirements.

Q: How does RoHS compliance differ between the main part and its substitute?
A: SMBJ5932C/TR13 is RoHS non-compliant. 1SMB5932B-13 is ROHS3 compliant. This difference is relevant for applications subject to environmental directives.

Q: Are there differences in electrical performance between the main and substitute parts?
A: Both diodes offer a nominal 20 V Zener voltage and 14 Ohms maximum impedance. Tolerance and power rating differ, with SMBJ5932C/TR13 having tighter tolerance (±2%) and higher power rating (2 W), compared to 1SMB5932B-13 (±5%, 550 mW).

Q: What is the range of operating temperatures for these Zener diodes?
A: Both parts are specified for an operating temperature range of -65°C to 150°C.

Q: Can parts be interchanged based on supplier device package?
A: Both SMBJ5932C/TR13 and 1SMB5932B-13 use comparable DO-214AA, SMB surface-mount packaging, and have identical mounting compatibility.
