Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined strictly according to the following allowed parameters: filter type, configuration, AC voltage ratings (phase to ground/neutral and phase to phase), current rating, frequency range, application, approval agency listings, operating temperature range, mounting type, termination style, RoHS and REACH compliance status. Only parts with comparable performance in these criteria are considered eligible substitutes for the FN258L-42-33 in three phase (Delta) EMC/EMI line filter applications.

Parameter Comparison

Engineering Selection Recommendations

FN258L-42-33 is obsolete. For applications requiring continued availability, substitute part numbers FN3288-40-33-C17-R65 and FN3288-40-33-C35-R65 from Schaffner EMC Inc. meet the defined criteria. Both substitutes are ROHS3 compliant, REACH unaffected, and feature terminal block termination and chassis mount structure. Substitute parts offer ENEC and UR approvals, along with CE certification. Selection between substitute parts can be based on packaging preference and active product status, ensuring regulatory compliance and ongoing availability.
