Substitute Part Grouping Explanation

Substitute identification for DC-DC converters such as UVQ-12/10-D48NB-C must be based solely on matching both critical electrical and mechanical parameters. The provided substitute part, UEE-12/12.5-D48NB-C, was selected as it meets all specified requirements for input voltage range, output voltage, isolation voltage, number of outputs, mounting type, and package/case. Series and features must also align with the necessary application requirements. Regulatory and environmental compliance, part status, and product certifications are also considered for direct equivalency.

Critical comparison is based on these parameters:

• Input voltage range
• Output voltage and output current maximum
• Isolation rating
• Features
• Mounting type and package/case
• Series and part status
• Compliance and certifications

Engineering Selection Recommendations

The Murata UVQ-12/10-D48NB-C is listed as Obsolete. The substitute part, UEE-12/12.5-D48NB-C, carries an Active status, with compliance certifications including RoHS3 and REACH unaffected. Both components share identical input and output voltage ratings, output isolation voltage, mounting type, and control features. Substitute selection based on part status and compliance certifications ensures suitability for regulated production environments and authorized substitution in documentation.

Frequently Asked Questions (FAQ)

Q1: What determines a valid substitute for UVQ-12/10-D48NB-C?
A: Only parts with identical or compatible input voltage range, output voltage, output isolation voltage, mounting type, package/case, and intended application (ITE Commercial) are allowable substitutes. Compliance status and regulatory certifications must also be matched.

Q2: Can UEE-12/12.5-D48NB-C directly replace UVQ-12/10-D48NB-C in a design?
A: UEE-12/12.5-D48NB-C matches all key electrical and mechanical parameters and is listed by the manufacturer as a substitute. Any compatibility consideration is within allowed parameters.

Q3: Are there physical differences to consider in replacement?
A: Package dimensions differ in width: UVQ-12/10-D48NB-C (1.45") versus UEE-12/12.5-D48NB-C (0.90"), both with identical length and height, and both in 8-DIP Module format. This should be verified against mechanical requirements for PCBs.

Q4: Is the substitute part compliant with environmental and regulatory standards?
A: UEE-12/12.5-D48NB-C is ROHS3 compliant and REACH unaffected, matching the required compliance status as specified for UVQ-12/10-D48NB-C.

Q5: Does efficiency or maximum output current affect substitution eligibility?
A: The substitute offers a higher output current (12.5A) and higher efficiency (93%), but still meets the specified minimum requirements from the original part. Only parameters provided are considered for eligibility.
