NMK1209SC Equivalent & Substitute Parts Reference

Part Overview

The Murata Power Solutions Inc. NMK1209SC is an obsolete isolated DC-DC converter module, designed for applications requiring dual output voltages of +9V and -9V at 111mA each, with up to 2W power capability. This through-hole, 7-SIP module is suited for ITE (Commercial) environments and offers 3 kV isolation. Since the NMK1209SC is obsolete, identifying compatible substitute parts is required to maintain system functionality and supply continuity, especially in existing or service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching the following essential electrical, mechanical, and compliance parameters:

• Isolated module type
• Dual output (+9V, -9V) configuration
• Input voltage range of 10.8V to 13.2V
• Maximum output current of 111mA per output
• 2W output power
• Through-hole mounting, 7-SIP 5-lead package
• Operating temperature range of -40°C ~ 85°C
• RoHS3 compliance

Only parts meeting all the above parameters, as explicitly stated, are considered equivalent or substitutes. No assumptions have been made beyond provided data.
