Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching electrical and mechanical key parameters within the Diodes, Zener category. The criteria for compatibility include: package/case (DO-214AA, SMB), surface mount form factor, Zener voltage (12 V), tolerance range, power handling, maximum impedance, reverse leakage current, forward voltage at stated current, and the same operating temperature range. Only substitute parts that directly match or exceed these parameters are included.

Parameter Comparison

Engineering Selection Recommendations

Consider the product status, compliance, and certifications when selecting a substitute. SMBJ5927A/TR13 is currently active and RoHS non-compliant, while 1SMB5927BT3G is active and ROHS3 compliant. Both parts share identical category assignment, mounting type, package form factor, nominal Zener voltage, operating temperature range, maximum impedance, reverse leakage, and regulatory status (ECCN, REACH, HTSUS). For applications requiring strict RoHS compliance, 1SMB5927BT3G is suitable.

Frequently Asked Questions (FAQ)

Q1: How are substitute parts determined for Zener diodes?
Substitute parts are determined by matching electrical parameters such as Zener voltage, tolerance, power rating, impedance, reverse leakage current, and forward voltage, alongside mechanical attributes like package/case and mounting type.

Q2: Is package compatibility guaranteed between SMBJ5927A/TR13 and 1SMB5927BT3G?
Both models use the DO-214AA, SMB package and are surface mount, ensuring mechanical compatibility in typical board layouts specified for this package type.

Q3: Do substitute parts have the same environmental and regulatory certifications?
Both parts are unaffected by REACH and classified under ECCN EAR99 and HTSUS 8541.10.0050. RoHS conformity differs; SMBJ5927A/TR13 is RoHS non-compliant, while 1SMB5927BT3G is ROHS3 compliant.

Q4: Are the electrical performance parameters closely matched?
Key operational parameters such as Zener voltage, reverse leakage, impedance, and operating temperature are strictly matched. Differences exist in tolerance (±10% vs. ±5%), power rating (2 W vs. 3 W), and forward voltage (1.2 V vs. 1.5 V @ 200 mA), all disclosed above for engineering review.

Q5: What are the primary considerations for selecting a substitute for SMBJ5927A/TR13?
Select substitutes based on identical package, mounting type, Zener voltage, power handling, tolerance, and matched regulatory requirements as listed in the comparison table.
