Equivalent & Substitute Parts Reference for HPR112C

Part Overview

The Murata Power Solutions Inc. HPR112C is a DC DC Converter categorized as an isolated module, offering 1 output at 5V 150mA from 13.5V–16.5V input, with a rated power output of 1W and isolation voltage of 750V. The module is provided in a 7-SIP package (5 leads) for through-hole mounting, with operating temperature specified between -40°C and 100°C. As part of the HPR1xxC (0.75W) series, the HPR112C is currently listed as obsolete. Finding suitable substitute models is necessary for ongoing manufacturing, maintenance, or repair operations where form, fit, and function need to be maintained.

Key Parameters

Substitute Part Grouping Explanation

The substitute parts for HPR112C are selected strictly based on match with key technical parameters, including input voltage range (13.5V–16.5V), output voltage (5V), maximum output current (≥150mA), power rating (1 W), isolation type and voltage (≥750V), number of outputs (1), mounting type (through hole), package style (similar SIP form factor), and compliance statuses (RoHS3, REACH Unaffected, ECCN EAR99). Product status is also considered, prioritizing active models for ongoing availability. The parameters considered valid for substitution are:

• Input Voltage Range
• Output Voltage
• Maximum Output Current
• Power Rating
• Isolation Voltage
• Number of Outputs
• Mounting Type
• Package Type and Dimensions
• Compliance (RoHS/REACH/ECCN/HTSUS)
• Operating Temperature Range

Parameter Comparison

Engineering Selection Recommendations

The MER1S1505SC (Murata Power Solutions Inc.) and RB-1505S (Recom Power) DC DC converters meet all provided key electrical, mechanical, and compliance criteria for direct substitution of the obsolete HPR112C part. Both alternatives are RoHS3 compliant, REACH unaffected, ECCN EAR99, and available in similar SIP modules for through-hole mounting. Their product status is listed as active, supporting continued availability for new designs and replacements.

Frequently Asked Questions (FAQ)

Q: What are the critical electrical parameters required for substituting HPR112C?
A: The substitute must match the input voltage range (13.5V–16.5V), output voltage (5V), output current (≥150mA), isolation voltage (≥750V), and power rating (1 W).

Q: Are MER1S1505SC and RB-1505S suitable for the same mounting and footprint as HPR112C?
A: Both substitutes feature through-hole mounting and SIP modules with comparable physical dimensions. Package lead count variations should be verified against socket or PCB layout requirements.

Q: How do the isolation voltages of the substitutes compare?
A: MER1S1505SC and RB-1505S both provide 1 kV isolation, exceeding the 750 V isolation provided by HPR112C.

Q: What compliance standards do the substitutes meet?
A: Both substitutes and the original part are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8504.40.9580.

Q: Is the operating temperature range of the substitutes compatible with HPR112C?
A: The substitutes support operating temperatures from -40°C to 85°C. HPR112C has a higher maximum temperature of 100°C; temperature requirements in the application should be checked accordingly.

Q: Can these substitutes be directly placed on the same PCB footprint as HPR112C?
A: The package style and dimensions are comparable. Lead configuration differences between parts should be validated for PCB compatibility.
