Equivalent & Substitute Parts Reference: MEV1D1209SC

Part Overview

The MEV1D1209SC by Murata Power Solutions Inc. is an isolated DC-DC converter module providing dual outputs of +9V and -9V at 56mA each, with a 1W maximum power rating. Suitable for commercial ITE applications, it features a 3kV isolation voltage and operates within an input voltage range of 10.8V to 13.2V, in a through-hole 7-SIP package. As this product is designated obsolete, it is necessary to identify appropriate substitute models based strictly on its essential electrical, mechanical, and compliance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped based strictly on the matching or compatible parameters: input voltage range, output voltage, output current, power rating, isolation voltage, operating temperature, efficiency, mounting type, and compliance certifications. Only parts meeting or exceeding these specifications within the provided data set are considered valid substitutes. Distinctions between single-output and dual-output configurations are explicitly acknowledged.

Parameter Comparison

Engineering Selection Recommendations

Both the main part MEV1D1209SC and substitute NMK1209SAC are listed with obsolete status. RoHS and REACH compliance are confirmed for both parts. Moisture Sensitivity Level is stated as Not Applicable, while ECCN classification and HTSUS codes match. Substitute selection is therefore based strictly on electrically compatible parameters and compliance certifications. Inventory availability is specified for both models.

Frequently Asked Questions (FAQ)

Q: What parameters must match for a DC-DC converter substitute to be considered equivalent?
A: Input voltage range, output voltage, output current, isolation voltage, operating temperature, efficiency, mounting type, and package/case dimensions must align with the original part.

Q: How does the output configuration affect substitution?
A: The MEV1D1209SC provides two outputs (+9V and -9V). Substitute NMK1209SAC provides a single output (9V). Substitution is limited by the output configuration; dual-output requirements must be addressed.

Q: Are package differences relevant in substitute selection?
A: Both parts utilize a 7-SIP through-hole package, but the number of leads and module width differs. Mechanical compatibility should be verified based only on the provided details.

Q: Do compliance certifications impact selection?
A: Both parts list RoHS and REACH compliance, ensuring adherence to material and environmental requirements for ITE commercial applications.

Q: Is it necessary to consider operating temperature in substitution?
A: Yes. Both parts specify -40°C to 85°C, confirming suitability for similar environmental conditions according to commercial standards.
