RM-0505S/EH Equivalent & Substitute Parts Reference
Part Overview
The RM-0505S/EH from Recom Power is an isolated DC-DC converter module with a single 5V output, rated for 50mA current and 250mW power. This component is classified as obsolete, having previously served applications in commercial ITE environments requiring 2kV isolation and SCP features. Given its product status, it is necessary to identify alternative compatible models within the same electrical, mechanical, and regulatory parameters for ongoing manufacture, service, and repair needs.

Substitute Part Grouping Explanation
Substitute part selection for the RM-0505S/EH is based strictly on matching the following key parameters: input voltage range (4.5V-5.5V), output voltage (5V), output current (50mA), output power (250mW), voltage isolation rating (2kV), number of outputs (1), SCP feature, through-hole 4-SIP package, body dimensions, compliance certificates (ROHS3, REACH), and relevant application scope. Substitution is validated only when all listed criteria are equivalent.
