Equivalent & Substitute Parts Reference for NDXD4815EC

Part Overview

NDXD4815EC by Murata Power Solutions Inc. is an isolated module DC-DC converter in the NDX (7.5W) series, designed for ITE (Commercial) applications. It provides dual outputs of +15V and -15V at up to 250mA, with a 36V–75V input range and 1 kV isolation. This product is currently obsolete; therefore, identifying substitute models is necessary to ensure continuity in designs requiring similar electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by strict matching of the following key parameters: number of outputs, input voltage range, output voltages, maximum output currents, power rating, operating temperature range, isolation voltage, mounting type, package style, and compliance information. Only parts meeting or closely aligning to these criteria are considered. NCS6D4815C is listed as a substitute due to relevant matches in output voltages, isolation, operating temperature, mounting, and application, as well as compliance parameters supplied.

Parameter Comparison

Engineering Selection Recommendations

NDXD4815EC is designated Obsolete. Substitute part NCS6D4815C is Active, ROHS3 compliant, and available in quantity. Compliance parameters and product status support direct selection for designs requiring continued supply and regulatory conformity. Both parts are available for through hole mounting.

Frequently Asked Questions (FAQ)

Q1: What defines appropriate substitution between DC-DC converters?
A: Substitution is strictly determined by the match of output voltages, output currents, input voltage range, number of outputs, isolation voltage, operating temperature, mounting type, packaging, efficiency, and compliance parameters.

Q2: Are package differences relevant when choosing a substitute?
A: Yes. NDXD4815EC uses a 6-DIP module, while NCS6D4815C utilizes a 24-DIP module (600 mil, 8 Leads). Mechanical compatibility should be confirmed in designs.

Q3: Does current or power rating variance affect substitution validity?
A: Maximum output current and total power must meet application requirements. NCS6D4815C supplies 200mA per output and 6W total; NDXD4815EC supplies 250mA and 7W.

Q4: How do compliance statuses impact selection?
A: Compliance information, such as ROHS3 and REACH, must match end-use requirements. NDXD4815EC is REACH unaffected, whereas NCS6D4815C is ROHS3 compliant and REACH affected.

Q5: Is operating temperature consistency required?
A: Both models feature -40°C ~ 85°C ranges, ensuring suitability for similar environments.

Q6: Is input voltage range compatibility important?
A: Yes. NDXD4815EC requires 36V–75V; NCS6D4815C operates from 18V–75V. Designs with supply voltages in the former’s range will be supported by the latter.
