Selection Guidelines

Choose this model if you need compact, isolated 5V power with low current demand and input voltages between 10.8V and 13.2V

Ensure load requirements do not exceed 21mA

Check compatibility with through-hole DIP package

Confirm environmental specs and moisture tolerance for your application

Verify that the isolation voltage, power rating, and temperature specs line up with your system’s needs

Usage Considerations

Product is obsolete—check availability and future support

Observe maximum input/output ratings to prevent damage

Keep output current below 21mA for reliability

Ensure operating temperature remains within specified 0°C to 70°C

Install in compatible PCB footprint (7-DIP, 4 leads)

Utilize short-circuit protection when designing for safety

Consider using an alternative if ongoing supply is critical

Potential Equivalent/Replacement Models

There may be similar DC-DC converter modules from Murata Power Solutions or other brands, but direct drop-in replacements may not be available due to obsolescence and unique specs. Suggested alternatives: Other Murata LME12 series converters, C&D Technologies NME12 series, or recom equivalents – these may have differences in pinout, power, sizing, voltage, or current ratings; always check specifications for compatibility.
