Engineering Selection Recommendations

The CME375-8-B is a direct equivalent substitute for the CME375-8. Both components are manufactured by Triad Magnetics within the CME series and share identical electrical specifications, mechanical dimensions, and compliance certifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

CME375-8: 1050 pieces in stock. Primary selection for immediate procurement.

CME375-8-B: 640 pieces in stock. Alternative selection when primary part availability is limited.

Both parts maintain active product status and full compliance with CSA, IEC, UL, and VDE standards. Both are ROHS3 compliant and REACH unaffected. The through-hole mounting configuration and vertical 4-pin package ensure identical PCB layout compatibility. Operating temperature range, voltage ratings, and all electrical parameters are identical, confirming full interchangeability in power line filtering applications.
