HPR402C Equivalent & Substitute Parts Reference

Part Overview

The HPR402C from Murata Power Solutions Inc. is an isolated module DC DC converter featuring a single 15V output at a maximum current of 50mA, rated for 750mW power. It supports an input voltage range of 4.5V to 5.5V and provides a 3kV isolation voltage. This DC DC converter is classified as obsolete, necessitating the identification of alternative models with compatible electrical, mechanical, and compliance specifications for continued design support, repair, or manufacturing.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly established by matching mandatory electrical and mechanical parameters, including: module type, number of outputs, input voltage range, output voltage, output current, isolation voltage, mounting type, package/case dimensions, and environmental compliance (RoHS, REACH, MSL). Only components from the same manufacturer and with equal or superior ratings for power, isolation, and certifications, within the specified input voltage window, are included in consideration.

Parameter Comparison

Engineering Selection Recommendations

The HPR402C is designated as obsolete. The MEV1S0515SC satisfies all provided compliance requirements, including ROHS3 and REACH status, and matches the environmental MSL classification. Selection based solely on current product status and compliance supports MEV1S0515SC as a substitute for continued manufacturing or maintenance.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting DC DC converters in this category?
A1: Substitution requires matching type, number of outputs, input and output voltages, maximum output current, power rating, isolation voltage, mounting type, package/case, dimensions, and environmental compliance.

Q2: Is the MEV1S0515SC mechanically compatible with HPR402C?
A2: Both parts are through-hole modules with similar package dimensions, but the lead configuration differs between a 7-SIP (4 leads) and a 6-SIP (5 leads) module. Compatibility should be verified based on actual layout and mechanical fit using provided package information.

Q3: Can the MEV1S0515SC provide higher output current than the HPR402C?
A3: Yes, according to provided parameters, MEV1S0515SC supports up to 67mA current output versus 50mA for HPR402C.

Q4: Does the substitute part meet the same safety and compliance standards?
A4: Both parts are ROHS3 compliant, REACH unaffected, and have the same Moisture Sensitivity Level designation.

Q5: Are operating temperature ratings comparable?
A5: HPR402C operates from -40°C to 100°C; MEV1S0515SC operates from -40°C to 85°C. Selection must observe this difference where maximum operating temperature is a consideration.
