Key Parameters

Substitute Part Grouping Explanation

Substitution for single-phase EMC/EMI line filters is determined strictly by matching the following key electrical and mechanical parameters: filter type (single phase), configuration (two-stage), rated AC voltage (250V), current rating (3A), operating frequency (50/60Hz), mounting type (chassis mount), and termination style (quick connect). Approval agency certifications and RoHS/REACH compliance are also included as selection criteria. Only parts that meet all listed parameters are suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part 03ER11 is obsolete and RoHS non-compliant, whereas substitute part F1399AA03 is active and ROHS3 compliant. Both parts meet the mandatory electrical and mechanical parameters including filter type, configuration, voltage, current, frequency, mounting type, termination style, and approval agency certifications. For applications with RoHS compliance requirements, F1399AA03 meets those criteria while 03ER11 does not.
