Equivalent & Substitute Parts for NME1209DC

Part Overview

The NME1209DC from Murata Power Solutions Inc. is an isolated module DC-DC converter featuring a single 9V output at up to 111mA, operating from a 10.8V to 13.2V input. Designed for ITE (Commercial) applications, it delivers 1W of power with a 1 kV isolation voltage, and is housed in an 8-DIP Module, 4 Leads through-hole package. This device is categorized as obsolete, making it necessary to identify substitute models with equivalent electrical, mechanical, and compliance characteristics for continued design support or ongoing production.
