Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DC-DC converter modules within the Recom Power portfolio is strictly based on matching key electrical and mechanical parameters. These include input voltage range, output voltage and current, output power, isolation rating, operating temperature range, mounting type, package/case dimensions, number of outputs, application compatibility, efficiency, and feature set. The substitute must also comply with RoHS and REACH environmental directives, maintain the same moisture sensitivity level, and match trade compliance attributes.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on product status and compliance. REC15-123.4S/H3 is marked as obsolete; REC15-123.4S/H3/M is active. Both parts meet ROHS3 compliance, REACH unaffected status, the same MSL, and identical ECCN and HTSUS codes. The substitute provides identical key electrical and mechanical specifications, with added UVLO feature and medical application listing per provided data.
