Key Parameters

Substitute Part Grouping Explanation

Substitute grouping is determined exclusively by the following key parameters: Zener voltage (Vz), package/case type, mounting type, power rating, tolerance, maximum impedance (Zzt), reverse leakage current, and operating temperature range. Only substitutes strictly matching these fields are included, ensuring compatibility in terms of electrical operation, mechanical fit, and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Substitute part selection between SMBJ5342A/TR13 (Microchip Technology) and 1SMB5921B-13 (Diodes Incorporated) should consider product status (both active), RoHS and REACH compliance, and moisture sensitivity level (MSL 1). 1SMB5921B-13 offers ROHS3 compliance, which may be required for certain applications. Both parts share the same category, package type, mounting type, operating temperature range, and similar compliance codes.

Frequently Asked Questions (FAQ)

Q1: What are the most important criteria for substituting Zener diodes in this category? A1: Substitution is determined by Zener voltage (Vz), tolerance, power rating, impedance, reverse leakage current, operating temperature range, mounting type, and package/case compatibility.

Q2: Are SMBJ5342A/TR13 and 1SMB5921B-13 physically interchangeable? A2: Both parts use the DO-214AA, SMB package and surface mount type, which supports direct interchangeability in terms of mechanical fit.

Q3: What compliance and certification differences exist between the main part and substitute? A3: SMBJ5342A/TR13 is RoHS non-compliant, while 1SMB5921B-13 is ROHS3 Compliant. Both have MSL 1 (unlimited), REACH Unaffected status, and are classified under ECCN EAR99.

Q4: Does the difference in power rating and tolerance affect substitution? A4: Selection is strictly based on provided parameters. Verify that application requirements match the maximum power and voltage tolerance specified for substitute parts.

Q5: Can the substitute part be used in high-temperature surface mount assemblies? A5: Both SMBJ5342A/TR13 and 1SMB5921B-13 have an operating temperature range of -65°C ~ 150°C and are suitable for surface mount environments within this range.
