Parameter Comparison

Engineering Selection Recommendations

The MPI4020V2-2R2-R serves as a direct substitute for the MPI4040R4-2R2-F based on matching inductance specifications and identical mounting methodology. Both components are manufactured by Eaton - Electronics Division and maintain active product status, ensuring continued availability and supply chain reliability.

The substitute part provides enhanced compliance posture through ROHS3 certification, whereas the main part is RoHS non-compliant. This distinction becomes relevant in applications subject to RoHS regulatory requirements. Both components share identical MSL ratings, ECCN classifications, and HTSUS codes, confirming regulatory and logistical compatibility.

The substitute part includes detailed electrical specifications (current rating 3.8 A, DC resistance 48 Ohm Max, saturation current 5.5 A) and mechanical dimensions (0.160" L x 0.171" W, 0.079" height maximum), enabling precise circuit design validation. The shielded drum core wirewound construction and 33 MHz self-resonant frequency support high-frequency applications within the specified operating temperature range of -55°C to 125°C.

Selection between these components should be based on compliance requirements, inventory availability, and packaging format preferences (Tape & Reel for the substitute part).
