NMH2415DC Equivalent & Substitute Parts Reference

Part Overview

The NMH2415DC, manufactured by Murata Power Solutions Inc., is an isolated DC-DC converter module designed for ITE (Commercial) applications. This module provides two outputs of +15V and -15V at up to 67mA each, with a total power output of 2W. It operates over an input voltage range of 21.6V to 26.4V, features a 1 kV isolation voltage, and utilizes a through-hole 14-DIP package. The NMH2415DC is now classified as obsolete. It is therefore necessary to identify direct substitute parts to maintain design compatibility and ensure continued product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following parameters: number of outputs, input voltage range, output voltages and currents, total power, isolation voltage equal or higher, efficiency, mounting type, operating temperature range, package type, regulatory compliance (RoHS, REACH), and commercial application suitability. Mechanical dimensions and package pinout must also be considered, as provided.

Parameter Comparison

Engineering Selection Recommendations

The NMH2415DC is designated obsolete, while the NMK2415SC remains active and available. Both parts meet ROHS3 compliance and are REACH unaffected. The NMK2415SC offers a higher isolation voltage, higher efficiency, and supports the same electrical performance parameters as the NMH2415DC. Package and pinout differences must be evaluated for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q1: Which parameter differences should be considered first when selecting a substitute for NMH2415DC?
A1: Electrical specifications such as input range, output voltages, currents, total power, isolation voltage, and efficiency must all strictly match or exceed. Compliance (RoHS, REACH) and environmental ratings must also align.

Q2: Is NMK2415SC functionally equivalent to NMH2415DC?
A2: Based on provided parameters, NMK2415SC matches all critical electrical specifications and exceeds the isolation requirement. Package and pinout differences must be considered for mechanical fit.

Q3: Are there differences in package type or size that may affect substitution?
A3: Yes, NMH2415DC uses a 14-DIP 6-lead module, while NMK2415SC uses a 7-SIP 5-lead module. Size and mounting changes must be checked against board layout requirements.

Q4: Does the substitute NMK2415SC maintain regulatory compliance?
A4: NMK2415SC is ROHS3 compliant and REACH unaffected, meeting regulatory requirements stated for the original NMH2415DC.

Q5: Are any features or control functions present in one part but not the other?
A5: No features or control functions are stated for either part within the provided parameters. Only core DC-DC conversion is specified.
