Key Parameters

Substitute Part Grouping Explanation

Substitute qualification is strictly based on matching the isolated DC-DC converter category key parameters, specifically:

• Input Voltage Range
• Output Voltage
• Output Current
• Power Rating
• Isolation Voltage
• Number of Outputs
• Mounting Type
• Package / Case Dimensions
• Regulatory Compliance (RoHS, REACH, ECCN, HTSUS, MSL)
• Application Suitability
• Product Status

Only substitute models that meet or exceed these attributes in accordance with the provided part details are considered.

Parameter Comparison

Engineering Selection Recommendations

Substitution should be based on product status and compliance certifications. The original Murata Power Solutions UCH-5/20-D24PB-C is obsolete and RoHS compliant. The recommended substitute, Recom Power RP100H-2405SRW/P, is active and ROHS3 compliant, with matching regulatory identifiers (REACH, ECCN, HTSUS) and Moisture Sensitivity Level. These compliance attributes meet the requirements for direct replacement within category standards.

Frequently Asked Questions (FAQ)

Q1: What are the essential electrical parameters to match when selecting a substitute for the UCH-5/20-D24PB-C?
A1: Critical parameters include input voltage range, output voltage, output current, power rating, and isolation voltage. All must be exactly matched or exceeded in the substitute part.

Q2: Are there mechanical or mounting considerations when replacing the original module?
A2: Yes. Substitute modules must utilize through-hole mounting and fit the Half Brick or 1/2 Brick package dimensions as specified for system compatibility.

Q3: Is regulatory compliance required for direct substitution?
A3: Direct replacements must match RoHS and REACH compliance, as well as ECCN and HTSUS classification, to ensure conformity with global regulations.

Q4: Can features or performance attributes beyond what is specified influence compatibility?
A4: Only documented and provided electrical and mechanical attributes may be considered. No additional features are included in the substitution criteria.

Q5: How is the product status relevant to the selection process?
A5: Substitute selection is required as the main part, UCH-5/20-D24PB-C, is obsolete. An active part with equivalent parameters, such as RP100H-2405SRW/P, supports ongoing system production and maintenance.
