Equivalent & Substitute Parts for HPR103C

Part Overview

The Murata Power Solutions Inc. HPR103C is a DC-DC isolated module converter providing dual outputs of +5V and -5V at 75mA each, with an input voltage range of 4.5V to 5.5V and 750V isolation. The device is packaged in a 7-SIP module and is certified RoHS3 compliant. The HPR103C is now obsolete, with availability limited to existing inventory. As such, identifying strictly equivalent or substitute parts is necessary to maintain design continuity for applications requiring this specification set.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for DC-DC converters is strictly based on matching key electrical and mechanical parameters. For the HPR103C, these parameters are number of outputs (2), output voltage values (5V, -5V), maximum output current (minimum 75mA, per channel), input voltage range (4.5 to 5.5V), power rating (1 W), voltage isolation (minimum 750 V), mounting style (through hole), package type (7-SIP or compatible SIP), size/dimension, and RoHS/REACH compliance. Substitution is restricted to parts meeting or exceeding these criteria.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring continued availability, active status, and ongoing compliance, MEA1D0505SC should be used as a substitute for the Murata Power Solutions Inc. HPR103C. The substitute part maintains RoHS3 compliance, REACH unaffected status, equivalent or improved key electrical parameters, and is classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Which parameters are critical for substituting HPR103C DC-DC converters?
A: Substitution requires equivalent values for input voltage range, output voltages, number of outputs, maximum output current, output power rating, isolation voltage, mounting type, package/case, physical dimensions, and compliance status.

Q: Are the mounting and package types of HPR103C and MEA1D0505SC compatible?
A: Both models feature through-hole mounting and compatible SIP module dimensions (19.6mm x 6.1mm x 10.2mm). The HPR103C uses a 7-SIP module while the MEA1D0505SC uses a 6-SIP module, both with 5 leads.

Q: Can a substitute with higher output current or isolation voltage be used?
A: Substitute models such as the MEA1D0505SC provide equal or greater output current and isolation voltage without exceeding specifications.

Q: Is compliance with RoHS and REACH maintained with the substitute part?
A: Both the HPR103C and MEA1D0505SC are RoHS3 compliant and REACH unaffected.

Q: What certification status should be considered when selecting a substitute?
A: The substitute part must match or exceed the original part’s compliance, including RoHS, REACH, ECCN, and HTSUS classification.
