Equivalent & Substitute Parts for NMK1215SC

Part Overview

The Murata Power Solutions Inc. NMK1215SC is an isolated module DC-DC converter designed for ITE (commercial) applications. It features dual outputs of +15V and -15V at up to 67mA each, with a total power output of 2 W and an input voltage range of 10.8V to 13.2V. The device supports a through-hole mounting type using a 7-SIP module, 5 leads package. The active product status of NMK1215SC ensures availability; however, precise substitutes are required for design flexibility, supply chain security, or multi-sourcing.

Substitute Part Grouping Explanation

Substitute DC-DC converters are determined based on equivalence across several critical parameters that define functional and physical compatibility. For the NMK1215SC, substitute suitability strictly follows these parameters: number of outputs, input voltage range, output voltages, output current, power rating, isolation voltage, operating temperature, compliance (RoHS, REACH), mounting type, and package/case. Only those parts meeting all these parameters are considered equivalent for substitution.
