Substitute Part Grouping Explanation

Substitution of the ES2LJ R5G is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB
Reverse Recovery Time (trr): 35 ns
Voltage - Forward (Vf) (Max) @ If: 1.7 V @ 2 A

Parametric Equivalent Parts maintain identical electrical specifications and performance characteristics across all critical parameters. These parts are direct functional replacements with no derating or circuit modification required.

Similar Parts share the same voltage and package specifications but differ in one or more secondary parameters such as reverse recovery time, reverse leakage current, or capacitance. These parts are suitable for applications where the specific parameter variance does not impact circuit performance.

Packaging Variants within equivalent groups differ only in supplier packaging format (Cut Tape, Tape & Reel, or Digi-Reel) and do not affect electrical performance or mechanical fit.
