Substitute Part Grouping Explanation
Substitution for Murata MTE1S0503MC is determined strictly by matching key electrical and mechanical parameters for isolated module DC DC converters. Substitute models included must meet criteria for number of outputs (1), input voltage range (4.5V to 5.5V), output voltage (3.3V), output current (303mA), power rating (1W), voltage isolation (≥1kV), mounting type (surface mount), suitable applications, operating temperature, package or case format, and compliance status. These factors directly govern interchangeability within the isolated DC DC converter product family.
