Equivalent & Substitute Parts Reference: RB-0509S/H

Part Overview

RB-0509S/H, manufactured by Recom Power, is an active isolated DC-DC converter module delivering 9V at up to 111mA from a 4.5V to 5.5V input. It is categorized under isolated DC-DC converter modules, with a power rating of 1W and designed for ITE (Commercial) and Medical applications. Its through-hole 7-SIP module package, ROHS3 compliance, and wide operating temperature range make it suitable for commercial and precision applications. Identifying alternative models is fundamental for supply stability, inventory coverage, and maintaining design flexibility.
