HPR122C Equivalent & Substitute Parts Reference

Part Overview

The HPR122C from Murata Power Solutions Inc. is an isolated DC-DC converter module designed for applications requiring dual output voltages of +12V and -12V at a maximum current of 30mA each. With an input voltage range of 21.6V to 26.4V and a total output power of 1W, this through-hole 7-SIP module is suited for ITE (Commercial) use. The HPR122C is marked as obsolete. Therefore, it is necessary to identify alternative models with comparable parameters to maintain continuous supply and compatibility in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based on exact matching of key functional and form-factor parameters:

• Input Voltage Range: 21.6V - 26.4V
• Dual Output: 12V and -12V
• Output Power: 1 W
• Maximum Output Current: Equal or higher than 30mA for each channel
• Module Type: Isolated
• Mounting: Through Hole
• Package/Case: 7-SIP Module, 5 leads
• RoHS Compliance

Substitutes listed meet these criteria, ensuring direct compatibility in electronic designs previously utilizing the HPR122C.

Parameter Comparison

Engineering Selection Recommendations

The HPR122C is obsolete and listed as ROHS3 compliant. Substitute part numbers RB-2412D and R24P12D are ROHS3 compliant, active, and share matching key operational and form-factor parameters. Both are available in through-hole 7-SIP module packaging, with comparable or higher output current and isolation voltage parameters. Their compliance certifications and product status satisfy substitution requirements for new designs and ongoing support of existing applications requiring the obsolete HPR122C.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for direct substitution in isolated DC-DC converter modules?
A1: Compatible substitution requires matching input voltage range, identical output voltages, equal or higher output current, same power rating, matching package/case type, mounting type, and RoHS compliance.

Q2: Are output current differences significant in these substitutes?
A2: Both RB-2412D and R24P12D offer higher maximum output current compared to HPR122C, which meets or exceeds the original requirements.

Q3: Is the 7-SIP Module, 5 Leads package consistent across substitutes?
A3: Yes. All listed substitutes utilize the 7-SIP Module, 5 Leads format for direct physical compatibility.

Q4: How do operating temperature ranges affect interchangeability?
A4: Substitute modules feature operating temperature ranges within or exceeding the requirements of the HPR122C (-40°C ~ 100°C) for broad application compatibility.

Q5: Are substitute modules compliant with environmental certifications?
A5: Both substitute part numbers are ROHS3 compliant, matching the original part's environmental certification.

Q6: What is the significance of product status for substitution?
A6: Substitute parts are currently active, ensuring ongoing availability for both current and future design requirements where the HPR122C was previously specified.

Q7: Does the isolation voltage impact substitution eligibility?
A7: Substitute modules present equal or higher isolation voltage ratings, maintaining necessary isolation performance and safety for ITE (Commercial) applications.
