NMJ1212SC Equivalent & Substitute Parts Reference

Part Overview

The NMJ1212SC, manufactured by Murata Power Solutions Inc., is an active, isolated DC-DC converter module designed for ITE (Commercial) applications. It delivers dual outputs of +12V and -12V at a maximum current of 42mA each, with a 1W power rating and high isolation voltage of 5.2 kV. Finding alternative models is necessary for design flexibility, supply security, and lifecycle management, particularly when exact specifications, regulatory certifications, and packaging formats must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly by matching the following key parameters: number of outputs, output voltage and current ratings, total power, input voltage range, isolation voltage, mounting type, package style and dimensions, RoHS and REACH compliance, and moisture sensitivity level (MSL). Only parts meeting these electrical, mechanical, and compliance requirements are grouped as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both NMJ1212SC and R05P15S/R8 are active products, RoHS3 compliant, have unlimited MSL ratings, and meet REACH requirements. They are available in through-hole SIP packages of similar dimensions.

Frequently Asked Questions (FAQ)

Q: What are the primary criteria for substituting the NMJ1212SC with other DC-DC converter modules?
A: Substitution is based on number of outputs, output voltage and current ratings, power rating, input voltage range, isolation voltage, mounting type, package/case, RoHS and REACH compliance, and MSL rating.

Q: Are the package types and mounting options equivalent between the primary and substitute parts?
A: Both parts are offered in 7-SIP through-hole module formats with similar physical sizes.

Q: Do both NMJ1212SC and R05P15S/R8 comply with the same environmental standards?
A: Both parts are ROHS3 compliant and REACH unaffected, with an MSL of 1 (Unlimited).

Q: Is the number of outputs and output voltages the same between NMJ1212SC and R05P15S/R8?
A: NMJ1212SC provides two outputs (+12V and -12V), while R05P15S/R8 offers a single 15V output.

Q: Can output current or power differences affect substitute part choice?
A: All provided substitute parts must have current and power ratings matching or exceeding those of the NMJ1212SC as specified in the comparison table.
