Equivalent & Substitute Parts for ULE-12/4.2-D48N-C

Part Overview

The Murata Power Solutions ULE-12/4.2-D48N-C is an isolated DC-DC converter module designed for ITE (Commercial) applications, delivering 12V at up to 4.2A (50W) from a 36V–75V DC input. It features through-hole mounting, remote on/off, overcurrent, overtemperature, and undervoltage lockout protections, and a 2.25 kV isolation voltage. This module is obsolete, creating a requirement for compatible substitute models to ensure continuity in designs and maintenance support for legacy systems.

Substitute Part Grouping Explanation

Substitute part selection for DC-DC converter isolated modules is based on a direct match for voltage input range, output voltage, output type, isolation voltage, mounting style, package, and protection features, along with matching or exceeding output current and power requirements. Compatibility is ensured by aligning the following key parameters: voltage input range (36V-75V), output voltage (12V), number of outputs (1), voltage isolation (2.25 kV), mounting type (through hole), package (8-DIP Module, 1/8 Brick), operating temperature range (-40°C ~ 85°C), and protection features. Substitute parts must also meet equivalent compliance and certification standards.

Parameter Comparison

Engineering Selection Recommendations

The ULE-12/4.2-D48N-C is obsolete and listed as such. Substitute selection is based on maintaining compliance with REACH, ECCN EAR99, and HTSUS 8504.40.9580 classifications. Both main and substitute parts offer Moisture Sensitivity Level (MSL) 1 (Unlimited), identical REACH status, and identical regulatory coverage, ensuring compatibility in regulated applications. Substitute parts must match or exceed these certifications and the specified regulatory classifications.

Frequently Asked Questions (FAQ)

Q1: What key parameters must be matched when substituting DC-DC isolated modules like ULE-12/4.2-D48N-C?
A1: Input voltage range, output voltage, number of outputs, isolation voltage, mounting type, package or case, output current (must be equal or higher), operating temperature range, protection features, and compliance certifications.

Q2: Is the package size critical when selecting a substitute for ULE-12/4.2-D48N-C?
A2: Yes. The ULE-12/4.2-D48N-C and UEE-12/12.5-D48N-C both use the 8-DIP Module, 1/8 Brick package with closely matching dimensions, supporting mechanical compatibility.

Q3: Can UEE-12/12.5-D48N-C deliver higher output current than ULE-12/4.2-D48N-C?
A3: Yes. UEE-12/12.5-D48N-C supports up to 12.5A versus 4.2A, and matches all key electrical and mechanical parameters specified.

Q4: Are application areas (ITE Commercial) and protection features compatible?
A4: Both modules are specified for ITE (Commercial) use and provide required protection features, based exclusively on their listed functions.

Q5: Does substitution affect regulatory and compliance classification?
A5: No. Both modules are classified under the same ECCN and HTSUS codes, and share identical REACH and Moisture Sensitivity Levels.

Q6: Is the substitute part active and currently available?
A6: Yes. UEE-12/12.5-D48N-C is marked as Active, providing a direct substitute for the obsolete ULE-12/4.2-D48N-C.
