Equivalent & Substitute Parts for HPR404C

Part Overview

The Murata Power Solutions HPR404C is a DC-DC converter providing isolated dual outputs of +12V and -12V with a combined power rating of 750 mW. It operates from a 4.5V to 5.5V input, features 3 kV isolation, and is housed in a 7-SIP Module with through-hole mounting. This part is designated as obsolete. As a result, identifying alternative models with strictly matching electrical and mechanical parameters is necessary for ongoing or future designs requiring form, fit, and function replacement.

Substitute Part Grouping Explanation

Substitution is based strictly on matched electrical and mechanical parameters: input and output voltage range, number of outputs, maximum output current, power rating, voltage isolation, mounting type, package/case dimensions, and environmental/compliance criteria. Only parts with these parameters fully matching or within defined limits of the original part number HPR404C are considered suitable equivalents in the DC-DC isolated module component category.

Engineering Selection Recommendations

The primary selection driver is the obsolete status of HPR404C. CMR0512S3C is active and provides strictly matched electrical, mechanical, and compliance parameters, including RoHS3 and REACH status. Both modules are produced by Murata Power Solutions and share comparable form factor and safety classifications.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting HPR404C with another DC-DC converter module?
A1: Substitution requires matching the number of outputs, input and output voltage ranges, maximum output current, isolation voltage, power rating, mounting type, package/case size, and regulatory compliance (RoHS, REACH).

Q2: Is the CMR0512S3C directly compatible with the footprint of HPR404C?
A2: Both use a 7-SIP Module with 5 Leads and similar dimensions, supporting direct mechanical compatibility.

Q3: Does the substitute part offer the same environmental compliance certifications?
A3: Both modules are ROHS3 compliant and REACH unaffected.

Q4: Should differences in efficiency or operating temperature affect substitution?
A4: As per allowed criteria, both parts meet or exceed the original specifications and are approved for substitution within the defined input parameters.

Q5: Can the substitute be used in the same ITE (Commercial) applications?
A5: Both HPR404C and CMR0512S3C are categorized for ITE (Commercial) applications.
