Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching key electrical and mechanical parameters: Zener voltage (10 V), tolerance (±5%), power rating (5 W), impedance (2 Ohms), reverse leakage current (5 µA @ 7.6 V), operating temperature range (-55°C ~ 150°C), mounting type (Surface Mount), and identical package (DO-214AB, SMC). Active product status is required. Only parts that meet these criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both CZRC5347B-HF and 1SMC5347-AU_R1_000A1 are active products with matching key electrical and mechanical parameters. 1SMC5347-AU_R1_000A1 provides additional compliance with AEC-Q101 and ROHS3, which may be required for automotive or environmental standards. When selecting a substitute, ensure product status is active and compliance certifications match specific application requirements. Only substitute with parts matching the defined key parameters.
