Equivalent & Substitute Parts Reference for Murata Power Solutions Inc. UVQ-5/20-D48NB-C
Part Overview
The Murata Power Solutions Inc. UVQ-5/20-D48NB-C is a DC-DC isolated module converter providing a single 5V output at up to 20A from an input range of 36V to 75V, with total power output of 100W. Key features include remote on/off, over current protection (OCP), over temperature protection (OTP), over voltage protection (OVP), short circuit protection (SCP), and under voltage lockout (UVLO). The product is currently designated as "Obsolete," which necessitates identification of equivalent or substitute models to maintain compatibility in applications where this converter is specified or used.

Engineering Selection Recommendations
Product status and compliance indicators are used for selection. The UVQ-5/20-D48NB-C is obsolete. UEE-5/30-D48NB-C is specified as active, RoHS3 compliant, and meets MSL 1 (Unlimited) and REACH unaffected criteria. Substitution is strictly supported between these models based on product status and provided regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Which parameters must be matched when substituting isolated DC-DC converter modules?
A: Substitution is based only on matching manufacturer, input voltage range, output voltage, type (isolated module), number of outputs, mounting type, package/case, control features, and compliance/certification status.
Q: Can the UEE-5/30-D48NB-C fully replace the UVQ-5/20-D48NB-C in the same footprint?
A: Package/case sizes differ. Both use 8-DIP module but have distinct brick sizes (1/4 vs. 1/8 Brick), and width dimensions are not identical. Mechanical compatibility must be verified according to the specified mechanical parameters.
Q: Does the substitute part provide at least the same maximum output current and power capacity?
A: The UEE-5/30-D48NB-C supports higher output (30A, 150W) compared to the UVQ-5/20-D48NB-C (20A, 100W) with the same output voltage.
Q: Are operational temperature ranges identical between the two models?
A: The UVQ-5/20-D48NB-C specifies -40°C to 110°C and the UEE-5/30-D48NB-C specifies -40°C to 85°C.
Q: Are both parts compliant with Moisture Sensitivity Level (MSL) 1?
A: Yes, both units are designated MSL 1 (Unlimited).
Q: What regulatory environmental statuses are provided?
A: UEE-5/30-D48NB-C is stated as RoHS3 compliant and REACH unaffected. UVQ-5/20-D48NB-C is REACH unaffected.
