Equivalent & Substitute Parts for MPDKN117S

Part Overview

MPDKN117S from Murata Power Solutions Inc. is an isolated DC-DC converter module, providing a single 3.3V output at up to 20A with an input voltage range of 36V to 75V and a maximum power output of 66W. It is designed for ITE (Commercial) applications and features through-hole mounting in an 8-DIP, 1/8 brick form factor. The device is currently designated as Obsolete, which necessitates identifying alternative models for continued production support and supply chain continuity.

Engineering Selection Recommendations

MPDKN117S is classified as Obsolete, while EQW020A0F1Z and SQE48T20033-NGB0G are both Active. All substitute models support the same electrical ratings, mechanical mounting, and application category. RoHS and REACH status are provided for substitutes; Obsolete status for the original part precludes continued manufacturing. Substitutes meet provided compliance status for regulatory and environmental considerations as detailed in the input.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for a substitute to be suitable for MPDKN117S?
A1: Input voltage range, output voltage, output current, output power, voltage isolation, operating temperature, application classification, mounting style, and package/case attributes must all align with MPDKN117S.

Q2: Can these substitute DC-DC converters be used in the same application as MPDKN117S?
A2: All listed substitutes are specified for ITE (Commercial) applications and provide identical electrical ratings and functional categories as MPDKN117S.

Q3: Are the form factors and mounting types consistent among the original and substitute parts?
A3: All components use an 8-DIP Module, 1/8 Brick package in a through-hole mounting configuration; physical dimensions are comparable.

Q4: Does the voltage isolation rating vary among these options?
A4: MPDKN117S and EQW020A0F1Z feature a 1.5kV isolation rating; SQE48T20033-NGB0G provides 2kV isolation.

Q5: How should compliance and part status inform the selection among these options?
A5: Active status of EQW020A0F1Z and SQE48T20033-NGB0G supports ongoing availability; compliance attributes, including RoHS and REACH status, are indicated in the provided data for detailed environmental requirements.
