Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following parameters: nominal Zener voltage (9.1 V), tolerance (±5%), maximum power dissipation (500 mW), maximum impedance (200 Ohms), operating temperature range (-65°C to 175°C), package/case (DO-213AA), mounting type (Surface Mount), and RoHS/REACH compliance status. Both electrical and mechanical parameters must align within the specified product group to ensure form, fit, and function compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both CDLL4772A and JANTX1N4103UR-1 are active devices supplied in the DO-213AA surface-mount package, with identical nominal Zener voltage, tolerance, power rating, impedance, and operating temperature range. Both parts are RoHS non-compliant and REACH unaffected. JANTX1N4103UR-1 includes a military qualification (MIL-PRF-19500/435) not present in CDLL4772A. Selection should be based on product status, package, and compliance parameters as provided.
