Engineering Selection Recommendations

Primary Substitute: RP20-4815DFR/XC

The RP20-4815DFR/XC is the direct functional equivalent of the obsolete RP20-4815DFR. Selection of this substitute is based on the following engineering criteria:

Product Status Consideration: The RP20-4815DFR/XC maintains active product status with Recom Power, ensuring ongoing availability and supply chain reliability. The original RP20-4815DFR is classified as obsolete, making the substitute the appropriate choice for new designs and component replenishment.

Electrical and Mechanical Compatibility: All critical electrical parameters are identical: dual ±15V outputs, 20W power rating, 667mA per output, 1.6 kV isolation, and identical protection features (OCP, OVP, SCP, UVLO). Mechanical compatibility is confirmed through identical through-hole mounting, 6-DIP package format, and physical dimensions of 50.8mm × 25.4mm × 10.2mm.

Compliance and Certification: Both parts maintain ROHS3 compliance, MSL 1 rating, and identical ECCN and HTSUS classifications. No additional compliance verification is required for substitution.

Series Differentiation: The substitute operates within the ECONOLINE RP20-FR series, while the original operates within the POWERLINE RP20-FR series. Both series share identical electrical and mechanical specifications for this model, with the ECONOLINE series representing the current production line.

Packaging: The substitute is supplied in tube packaging format, which is standard for active production components. The original was supplied in standard packaging. Both formats are compatible with standard component handling and assembly processes.
