SFS30483R3B Equivalent & Substitute Parts Reference

Part Overview

The Cosel USA, Inc. SFS30483R3B is an obsolete DC DC converter in the isolated module category, providing 3.3V at up to 9A from a 36V–76V input, with a 30W output and 1.5kV isolation. Suitable for ITE (Commercial) applications, this part is RoHS3 compliant and available in a 20-SMD Module, 17 Leads package. Due to its obsolete status, it is necessary to identify suitable substitute models with matching core electrical, mechanical, and compliance parameters for maintaining existing system compatibility.
