Power Line Filter Modules Procurement Notes

This component is officially listed as obsolete by TDK-Lambda. The product was discontinued on May 9, 2011. The final order date was June 30, 2014, with the last shipment occurring on December 31, 2014. Procurement must rely on secondary market availability or verified replacement parts such as the RSEL-2003M, noting that compatibility is not guaranteed.

Power Line Filter Modules Selection Notes

Designers should account for the obsolete status when selecting this filter. While the MAW-1203-22 offers a 3A rating and 250V capability in a low-profile shielded case, long-term supply chain stability is compromised. Verification of legacy stock or transition to recommended substitutes like the RSEL-2003M is required for new designs.

Power Line Filter Modules Part Context

The MAW-1203-22 belongs to the MAW series of single-stage EMC filters manufactured by TDK-Lambda. These filters are engineered for applications requiring effective noise suppression in single-phase environments. The series typically employs shielded metal cases to ensure robust performance against electromagnetic interference.

Power Line Filter Modules Replacement Considerations

TDK-Lambda recommends the RSEL-2003M as a substitute part number. Users must verify functional compatibility independently, as cross-compatibility is not explicitly guaranteed by the manufacturer.
