NMV1209DC Equivalent & Substitute Parts Reference

Part Overview

The Murata Power Solutions Inc. NMV1209DC is an obsolete isolated DC-DC converter module, providing two outputs of +9V and -9V at a maximum of 55mA each, with a power rating of 1W and an input voltage range of 10.8V to 13.2V. It is designed for ITE (Commercial) applications and features 3kV isolation and through-hole mounting in a 14-DIP module. Due to its obsolete product status, sourcing direct replacements is no longer feasible, necessitating the identification of substitute models with strictly matching electrical and mechanical key parameters for continued system support or maintenance.

Key Parameters

Substitute Part Grouping Explanation

Equivalent and substitute parts for the NMV1209DC are determined by matching the following parameters: manufacturer, module type, number of outputs, input voltage range, output voltages, output currents, power rating, isolation voltage, intended applications, operating temperature range, mounting type, package or case type, size or dimension, and compliance with relevant RoHS and REACH standards. Only parts strictly within these criteria are suitable as direct replacements.

Parameter Comparison

Engineering Selection Recommendations

The NMV1209DC is classified as obsolete. The NKA1209SC is an active and manufacturer-recommended substitute that matches all RoHS and REACH compliance statuses as well as the ECCN and HTSUS designations. Both parts support ITE (Commercial) applications and have equivalent electrical isolation, output configuration, and input characteristics. Differences exist in package and mechanical dimensions and must be reviewed in accordance with system mechanical constraints.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for the NMV1209DC?
A1: The key criteria are matching the module type, input voltage range, number and values of outputs, output current and power ratings, isolation voltage, application type, operating temperature range, compliance with RoHS and REACH, and comparable mounting style and dimensions.

Q2: Can NKA1209SC be used as a drop-in replacement for NMV1209DC?
A2: NKA1209SC meets all electrical and functional parameters required for substitution. Package, lead count, and dimensions differ and must be reviewed for mechanical compatibility.

Q3: Are there differences in compliance or certification between NMV1209DC and NKA1209SC?
A3: Both are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 and HTSUS 8504.40.9580.

Q4: What should be considered regarding the package/case when substituting?
A4: NMV1209DC utilizes a 14-DIP Module with 6 Leads, while NKA1209SC uses a 6-SIP Module with 5 Leads. Mechanical and PCB layout differences must be evaluated for compatibility.
