Substitute Part Grouping Explanation

Substitution decisions for the BZX84C11VLFHT116 are determined strictly by matching core electrical and mechanical parameters. These include Zener voltage (11 V), power rating (250 mW), maximum Zener impedance (20 Ohms), reverse leakage current at rated voltage (100 nA @ 8 V), tolerance, mounting type, package specifications, automotive grading, AEC-Q101 qualification, and all stated compliance designations. Substitute parts listed meet these constraints within the specified tolerance range and package options.
