Equivalent & Substitute Parts for NMJ1212SAC

Part Overview

The NMJ1212SAC from Murata Power Solutions Inc. is a DC DC converter in the isolated module category, providing a single 12V output at 1W with 5.2 kV isolation. It is an active product, suitable for ITE (commercial) applications, and features a through-hole 7-SIP module package with 4 leads. Situations such as supply chain constraints, long lead times, or manufacturer discontinuations may necessitate sourcing alternative models with strictly compatible electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if RP-1212S can substitute NMJ1212SAC?
A1: Substitution is based strictly on identical or compatible voltage input range, output voltage and current, isolation voltage, output count, power rating, mechanical footprint (7-SIP Module, 4 Leads), mounting type, operating temperature range, RoHS status, and MSL.

Q2: Are there any packaging differences between NMJ1212SAC and RP-1212S?
A2: Both parts share the 7-SIP Module, 4 Leads package and through-hole mounting type.

Q3: Is regulatory compliance maintained with the substitute part?
A3: Both NMJ1212SAC and RP-1212S are ROHS3 compliant and REACH unaffected, with MSL 1 (unlimited).

Q4: Can the substitute part be directly installed in a design using NMJ1212SAC?
A4: Electrical and mechanical parameters relevant for substitution, including package type and mounting, are strictly matched per the provided data.

Q5: Are there differences in the output current or power capabilities?
A5: The output currents are 83mA (NMJ1212SAC) and 84mA (RP-1212S), both with a 1W power rating.
