HPR123C Equivalent & Substitute Parts Reference

Part Overview

The HPR123C by Murata Power Solutions Inc. is an isolated module DC-DC converter providing dual outputs of +15V and -15V at 25mA each. It operates with a 21.6V to 26.4V input voltage, 1W output power, and is packaged in a 7-SIP Module with 5 leads. This product has achieved ROHS3 compliance and is classified as obsolete, making the identification of direct replacements essential for continued design support or maintenance requirements. Alternative models are necessary due to supply lifecycle constraints.

Substitute Part Grouping Explanation

Substitute parts for the HPR123C are selected based on strict adherence to the following key parameters: input voltage range (21.6V - 26.4V), dual output voltages (+15V, -15V), output power (1W), isolated module construction, mounting style (Through Hole), package type (7-SIP Module, 5 Leads), ROHS3 compliance, and matching or exceeding output current ratings. Only those parts matching these explicit criteria are included.

Engineering Selection Recommendations

The HPR123C is obsolete and listed as ROHS3 compliant. Substitute part MEA1D2415SC is currently active, maintains ROHS3 compliance, and matches all core mechanical and electrical interface requirements relevant to category substitution, based on the supplied parameters.

Frequently Asked Questions (FAQ)

Q1: Which parameters are crucial for selecting a substitute for HPR123C?
A1: Key parameters include input voltage range, number and value of outputs, maximum output current, output power, isolation voltage, mounting type, package type, and compliance certifications.

Q2: Are the package and footprint of MEA1D2415SC compatible with HPR123C?
A2: Both parts use the 7-SIP Module, 5 Leads case with matching dimensions, supporting compatibility for direct replacement in the same PCB footprint.

Q3: Is it necessary to check ROHS compliance for substitutes?
A3: Yes, matching ROHS status ensures substitutes meet the same environmental and regulatory requirements.

Q4: Does the differing operating temperature range affect substitution?
A4: Only the specified operating temperature ranges provided for each part are considered; any substitution must be strictly based on documented values.

Q5: Are other parts permitted as substitutes if not listed?
A5: Only parts meeting all the explicit, documented criteria in the supplied parameters are eligible for substitution.
