Equivalent & Substitute Parts Reference for NME2409SC

Part Overview

The NME2409SC by Murata Power Solutions Inc. is an obsolete isolated DC-DC converter module designed for single output applications requiring 9V at up to 111mA, with a 21.6V to 26.4V input range and 1W power rating. Its through-hole 4-SIP package and 1 kV isolation make it suitable for ITE (commercial) applications. Due to the product's obsolete status, it is necessary to identify direct substitutes that strictly match relevant electrical, mechanical, and compliance parameters for seamless component replacement.

Engineering Selection Recommendations

The main part, NME2409SC, is obsolete, and its substitute, MEE1S2409SC, is active. Both parts share compliance with REACH and EAR99 regulations, and the substitute part further adheres to ROHS3 standards. The substitute part’s operating temperature and MSL status remain compatible with ITE applications.

Frequently Asked Questions (FAQ)

Q1: What key parameters should be matched for DC-DC converter substitution?
A1: The input voltage range, output voltage/current, power rating, isolation voltage, mounting type, package/case, and intended application must be identical or directly compatible.

Q2: How does package/case dimension compatibility affect replacement?
A2: Both NME2409SC and MEE1S2409SC use the 4-SIP Module with closely matching dimensions, ensuring direct mechanical interchangeability.

Q3: Are there compliance differences to consider?
A3: Both parts meet REACH and EAR99 requirements; MEE1S2409SC also meets ROHS3 compliance, enhancing substitution suitability.

Q4: Can the substitute part operate in the same environments?
A4: The substitute part supports a wider operating temperature range, encompassing the requirements of the main part.

Q5: Is through-hole mounting type maintained?
A5: The substitute part retains the through-hole mounting type consistent with the original specification.
