NMA1512SC Equivalent & Substitute Parts Reference

Part Overview

NMA1512SC is a Murata Power Solutions isolated module DC-DC converter, providing two outputs at +12V and -12V with a total power of 1W. It operates over a 13.5V to 16.5V input range and is packaged in a 7-SIP module suitable for through-hole mounting. The product is obsoleted by the manufacturer, making it necessary to identify alternate models with matching electrical, mechanical, and environmental characteristics to maintain system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on the alignment of core electrical parameters (input voltage range, output voltage, output current, output power, isolation), mechanical format (mounting type, package size), and compliance factors (RoHS, REACH). These criteria ensure functional interchangeability within the product’s application domain. Only substitute models matching these criteria are included.

Key parameters considered:

• Input voltage range
• Output voltage and current ratings
• Output power
• Output isolation voltage
• Number of outputs
• Operating temperature range
• Mechanical package, mounting type, and dimensions
• Product compliance (RoHS, REACH)

Parameter Comparison

Engineering Selection Recommendations

NMA1512SC is obsolete. MEA1D1512SC is available, active, and maintains full RoHS3 and REACH compliance. Both share identical core electrical parameters, mounting style, and package configuration. The size and mechanical dimensions are closely matched between both models. The substitute part MEA1D1512SC can be directly selected as a replacement under these criteria.

Frequently Asked Questions (FAQ)

Q1: What core electrical criteria define substitutes for NMA1512SC in DC-DC converter applications?
A1: Substitute parts must match input voltage range, output voltages and currents, total output power, and isolation voltage. Compliance with the number of outputs and application type (ITE, Commercial) is also required.

Q2: Are package and mounting differences allowed when selecting substitutes?
A2: Only substitutes with identical mounting type (through hole), package/case (7-SIP Module, 5 Leads), and closely matched dimensions are considered.

Q3: What compliance factors are important when qualifying substitute DC-DC converters?
A3: Substitute models must be ROHS3 compliant and REACH unaffected, as provided.

Q4: Is a substitute with different efficiency acceptable?
A4: Efficiency is not listed as a substitute restriction when all other key parameters are matched.

Q5: Can a substitute part be used for the same commercial ITE applications as NMA1512SC?
A5: Yes, provided the substitute matches the same application classification and all other allowed electrical and mechanical parameters.
