Equivalent & Substitute Parts Reference: ULS-5/20-D48P-C

Part Overview

The Murata Power Solutions Inc. ULS-5/20-D48P-C is an isolated DC-DC converter module delivering a regulated 5V output at up to 20A from a 36V to 75V input range, with a 100W power rating. It features remote on/off, OTP, OVP, SCP, and UVLO protection in an 8-DIP Module, 1/16 Brick package. The product status is obsolete, which necessitates the identification of compatible substitute models to ensure continuity in design and maintenance for affected systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are selected based strictly on parameters relevant to electrical form, fit, and function as provided. The following criteria establish equivalence, ensuring correct operation and compliance:

• Type (Isolated Module)
• Input Voltage Range (36V – 75V)
• Output Voltage (5V)
• Output Current (Max 20A)
• Power Rating (100 W)
• Number of Outputs (1)
• Voltage Isolation (2.25 kV)
• Efficiency (91%)
• Features (Remote On/Off, OTP, OVP, SCP, UVLO)
• Operating Temperature Range (-40°C ~ 85°C)
• Mounting Type (Through Hole)
• Package / Case (8-DIP Module, 1/16 Brick)
• Size / Dimension (1.30" L x 0.90" W x 0.40" H)
• RoHS/REACH/ECCN/HTSUS compliance
• Moisture Sensitivity Level (1)

Substitute relationships are based exclusively on these matching parameters.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided data, the ULS-5/20-D48N-C is an active, in-production alternative that meets all electrical, mechanical, and environmental parameters for substitution. RoHS and REACH statuses are equivalent or superseded; both parts carry the same Moisture Sensitivity Level and supply chain classifications. The only control difference is the enable control logic (Active High versus Active Low), which must be considered in control circuit designs—no other differences are indicated within given parameters.

Frequently Asked Questions (FAQ)

Q1: What is the main criteria for substituting ULS-5/20-D48P-C with ULS-5/20-D48N-C?
A: Substitution is based on identical input/output voltage and current, power rating, isolation, features, mounting, size, package type, compliance, and environmental ratings.

Q2: Are there any differences in control logic between the original and substitute part?
A: Yes, the ULS-5/20-D48P-C has an 'Enable, Active High' control feature, while the ULS-5/20-D48N-C uses 'Enable, Active Low.' This must align with system control signal requirements.

Q3: Do both modules fit the same PCB and footprint?
A: Yes, both are specified in the 8-DIP Module, 1/16 Brick package with the same dimensions and through-hole mounting.

Q4: Is there any difference in compliance or environmental classifications?
A: No. Both parts are RoHS and REACH compliant, with MSL 1 (Unlimited), and share the same ECCN and HTSUS categorizations.

Q5: Is thermal performance or efficiency compromised with the substitute part?
A: No. Both specify an efficiency of 91% and an operating temperature range of -40°C to 85°C.

Q6: Can both modules be replaced without design or qualification changes?
A: Based on the provided parameters, all functional and mechanical specifications match except for enable logic polarity, which must be addressed at the system design level if necessary.
