NDY2403C Equivalent & Substitute Parts Reference

Part Overview

The NDY2403C, manufactured by Murata Power Solutions Inc., is an obsolete DC-DC converter in the isolated module product category. It outputs 3.3V at up to 909mA from an 18V to 36V input, delivering 3 W power with a 1 kV isolation rating in a 24-DIP through-hole package. As it is no longer in production, sourcing alternative DC-DC converters with matching electrical and mechanical parameters is necessary for continued application compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by matching the following key parameters: manufacturer, module type (isolated), input voltage range, output voltage, number of outputs, maximum output current, output power, voltage isolation rating, application suitability, operating temperature range, mounting type, compliance status, and packaging style. Substitute parts listed here meet these strict criteria as supported by the data provided.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on the product status of the NDY2403C as obsolete and the availability of NCS3S4803SC as an active product. Both parts are RoHS3 compliant. The main part has a REACH Unaffected status, while the substitute is REACH Affected. Only substitute parts with provided compliance information have been listed.

Frequently Asked Questions (FAQ)

Q: What are the critical criteria for substituting the NDY2403C?
A: Only DC-DC converters with matching output voltage, number of outputs, suitable input voltage range, isolated module type, mounting method, application suitability, and compliance status are considered.

Q: How does the package differ between NDY2403C and NCS3S4803SC?
A: The NDY2403C uses a 24-DIP Module, 8 Leads package, whereas the NCS3S4803SC uses an 8-DIP Module, 6 Leads package. Mechanical compatibility should be verified based on this provided data.

Q: Are there any differences in electrical characteristics between these parts?
A: Both target 3.3V output and 3 W output power. The substitute has lower maximum output current (700mA vs. 909mA), a wider input voltage range, and a higher isolation voltage (1.5 kV vs. 1 kV).

Q: What compliance differences exist between the main part and the substitute?
A: Both are RoHS3 compliant. The main part is REACH Unaffected; the substitute is REACH Affected.

Q: Can the NCS3S4803SC replace NDY2403C directly in all applications?
A: Substitution can only be considered based on the matching parameters provided: output voltage, input voltage range, power, isolation rating, and compliance. Package and lead differences are present.
