Equivalent & Substitute Parts Reference for NMA0509DC

Part Overview

The Murata Power Solutions Inc. NMA0509DC is an obsolete isolated DC-DC converter module, designed for ITE (commercial) applications. It features dual outputs (+9V and -9V) with a maximum 55mA output current, 1W power rating, and 1 kV isolation, in a through-hole 14-DIP module package. Because the NMA0509DC is obsolete, identifying equivalent or substitute parts that match the specified electrical and mechanical parameters is required for continued product support and design maintenance.

Key Parameters

Substitute Part Grouping Explanation

The substitute part listed is selected based strictly on matching electrical and mechanical parameters required for direct replacement in ITE (commercial) applications. Key parameters considered include number of outputs, input voltage range, output voltages and currents, total output power, output isolation voltage, efficiency, mounting type, package dimensions, operating temperature range, compliance statuses (RoHS3, REACH), and international trade classifications (ECCN, HTSUS).

Parameter Comparison

Engineering Selection Recommendations

The original NMA0509DC is obsolete. MEA1D0509SC from Murata Power Solutions Inc. is compliant with ROHS3, REACH, and shares the same ECCN and HTSUS codes. Both products are through-hole mounting isolated DC-DC converters for ITE (commercial) use, operating over the same voltage and temperature ranges. MEA1D0509SC is active and suitable for applications requiring continued product compliance and supply chain stability.

Frequently Asked Questions (FAQ)

Q: What criteria are used to determine equivalence for NMA0509DC substitute parts?
A: Equivalence is determined by matching number of outputs, input voltage range, output voltages and currents, isolation voltage, power rating, efficiency, mounting type, package dimensions, and environmental/compliance statuses.

Q: Are there any differences in package style or mounting between NMA0509DC and MEA1D0509SC?
A: NMA0509DC uses a 14-DIP Module, 6 Leads package, while MEA1D0509SC uses a 7-SIP Module, 5 Leads package. Both are through-hole mounting types.

Q: Is RoHS and REACH compliance maintained with the substitute MEA1D0509SC?
A: Yes, both NMA0509DC and MEA1D0509SC are ROHS3 compliant and REACH unaffected.

Q: Can MEA1D0509SC be used in all the same ITE (commercial) applications as NMA0509DC?
A: Provided application requirements are within the specified electrical and mechanical parameters listed, MEA1D0509SC meets the same input voltage, output voltages, current, power, and temperature ranges as NMA0509DC.

Q: What is the main difference in physical dimensions between the two models?
A: NMA0509DC measures 0.77" L x 0.39" W x 0.27" H (19.6mm x 9.9mm x 6.9mm); MEA1D0509SC is 0.77" L x 0.24" W x 0.40" H (19.7mm x 6.2mm x 10.2mm).

Q: Is there any difference in maximum output current?
A: NMA0509DC supplies up to 55mA per output; MEA1D0509SC supplies up to 56mA per output.
