NMK2412SC Equivalent & Substitute Parts Reference

Part Overview

The NMK2412SC, from Murata Power Solutions Inc., is an isolated DC-DC converter module providing +12V and -12V output voltages at up to 83mA per channel with an input voltage range of 21.6V to 26.4V and 2W maximum power. This through-hole, 7-SIP module is suitable for ITE (Commercial) applications and operates over a temperature range of -40°C to 85°C. The product status for NMK2412SC is marked as obsolete. When a product reaches obsolete status, it becomes necessary to identify suitable alternative models to ensure ongoing production and design support.

Substitute Part Grouping Explanation

Substitution is possible when a component exhibits electrical and mechanical compatibility with the original part. The allowed parameters for substitution in this category are:

Input Voltage Range (21.6V – 26.4V)
Output Voltages (+12V, -12V)
Maximum Output Currents (≥83mA per channel)
Maximum Power (2 W)
Number of Outputs (2)
Package/Case (7-SIP Module, 5 Leads)
Mounting Type (Through Hole)
Isolation Voltage (as listed)
Applications (ITE Commercial)
Operating Temperature Range (-40°C ~ 85°C)
Compliance Status (RoHS, REACH)

These parameters ensure proper functional equivalence and compatibility in most assemblies.

Engineering Selection Recommendations

Component selection is dictated by the product status and regulatory compliance. The NMK2412SC is obsolete, and the substitute RD-2412D is active with ROHS3 compliance and REACH unaffected status. Both options support ITE (Commercial) requirements. Only listed parameters and certifications should be used to support engineering selection.

Frequently Asked Questions (FAQ)

Q1: What are the defining substitution criteria for the NMK2412SC DC-DC converter?
A1: Substitution criteria are defined by matching input voltage range, output voltages and currents, number of outputs, total power, package type, mounting type, isolation voltage, application suitability, and compliance status.

Q2: Is the output current capability a direct match between NMK2412SC and RD-2412D?
A2: The RD-2412D provides 84mA output on both channels, compared to 83mA for the NMK2412SC.

Q3: Is the RD-2412D package/mechanical footprint compatible?
A3: Both NMK2412SC and RD-2412D use a 7-SIP Module, 5 Leads package and have matching mounting types.

Q4: Are regulatory compliance and certifications equivalent between the main and substitute parts?
A4: Both the NMK2412SC and RD-2412D are ROHS3 compliant and REACH unaffected.

Q5: What is the main difference in isolation voltage between these models?
A5: The NMK2412SC has an isolation voltage of 3 kV, while the RD-2412D offers 1 kV isolation.

Q6: Why is an alternative to the NMK2412SC necessary?
A6: The NMK2412SC is obsolete, requiring qualified substitutes for continued availability and support in designs.
