Equivalent & Substitute Parts Reference for NML1212SC

Part Overview

The Murata Power Solutions Inc. NML1212SC is an isolated DC-DC converter in the 4-SIP module category, specified for ITE (Commercial) applications. It delivers a single 12V output at a maximum of 167mA from a 10.8V to 13.2V input, with 2W output power and 1kV isolation. Its active product status and RoHS3 compliance ensure ongoing availability for current designs. Engineering processes often require identification of alternative models to maintain supply resilience, ensure form-fit-function compatibility, and accommodate sourcing strategies, especially in case of supply fluctuations or when preferred parts are on allocation.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are selected based strictly on identical or compatible key electrical and mechanical parameters. These include input voltage range, output voltage, output current or power, voltage isolation, operating temperature range, efficiency, number of outputs, mounting type, and package/case format. RoHS and REACH compliance are also required for regulatory alignment. Only substitutes which align with all specified parameters are included for consideration.

Key parameters for substitution:

• Input Voltage Range
• Output Voltage
• Output Current (or Power)
• Voltage Isolation
• Operating Temperature Range
• Number of Outputs
• Mounting Type
• Package/Case
• Compliance (RoHS/REACH)
• Product Status

Parameter Comparison

Engineering Selection Recommendations

Both NML1212SC (Murata Power Solutions Inc.) and RI-1212S (Recom Power) are active in their respective manufacturers’ portfolios, and both are ROHS3 compliant and REACH unaffected. These regulatory statuses support selection in compliant designs without the need for further qualification based on hazardous substances or reach requirements. The substitute RI-1212S also holds an unlimited Moisture Sensitivity Level (MSL 1), which can be considered where required. Include only substitutes matching official product status and regulatory compliance for direct interchange in qualified assemblies.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for a drop-in DC-DC converter substitution?
A: Input voltage range, output voltage, output current or power rating, voltage isolation, operating temperature range, number of outputs, mounting type, and package/case size must align for substitution.

Q2: Are there any compliance or certification requirements when using substitute parts?
A: Substitute parts must be compliant with RoHS and REACH for environmental and hazardous substances regulations. The NML1212SC and RI-1212S both meet ROHS3 compliance and REACH unaffected status.

Q3: Do package and mounting differences affect compatibility?
A: Both NML1212SC and RI-1212S use a 4-SIP Module and through-hole mounting, so no board-level package or mounting changes are required.

Q4: Does the size/dimension difference affect substitution?
A: Both parts use the 4-SIP Module package format, but exact mechanical fit should be confirmed based on the given length, width, and height values.

Q5: Is product status significant for selection?
A: Both the main and substitute DC-DC converter modules are active. Selection can proceed based on form-fit-function and compliance parameters.
