Substitute Part Grouping Explanation

Substitution of the UUG2G470MRQ1MS is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 400 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 2000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)

The substitute part UUG2G470MNJ6MS meets all electrical equivalence criteria. Physical dimensions differ slightly due to manufacturing optimization within the same product series, but both parts maintain compatible surface mount land patterns for standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The UUG2G470MNJ6MS is the direct substitute for the obsolete UUG2G470MRQ1MS. Both components are manufactured by Nichicon within the same UUG series and maintain identical electrical specifications across all critical parameters.

The substitute part carries Active product status, ensuring long-term availability and supply chain stability. The UUG2G470MNJ6MS is RoHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing.

Physical dimensions are reduced in the substitute part (18.00mm diameter versus 20.00mm), resulting in a more compact footprint while maintaining the same seated height. The smaller surface mount land size (19.10mm x 19.10mm versus 21.10mm x 21.10mm) accommodates standard PCB assembly processes without design modification.

Frequently Asked Questions (FAQ)

Q: Can the UUG2G470MNJ6MS be used as a direct replacement for the UUG2G470MRQ1MS?

A: Yes. Both parts are electrically equivalent across all specified parameters: 47 µF capacitance, 400 V voltage rating, ±20% tolerance, 2000 hour lifetime at 85°C, and identical operating temperature range. The substitute part is manufactured by the same supplier within the same product series.

Q: What are the physical differences between these parts?

A: The substitute part has a smaller diameter (18.00mm versus 20.00mm) and correspondingly smaller surface mount land size (19.10mm x 19.10mm versus 21.10mm x 21.10mm). Seated height remains identical at 22.50mm. These dimensional changes do not affect electrical performance or circuit functionality.

Q: Does the smaller footprint require PCB redesign?

A: No. The reduced land size of the substitute part is compatible with standard surface mount assembly processes. Existing PCB layouts may accommodate the smaller footprint without modification, or layouts can be optimized to take advantage of the reduced space requirement.

Q: What is the significance of the Active product status for the substitute part?

A: Active product status indicates that the UUG2G470MNJ6MS is currently manufactured and supported by Nichicon. This ensures reliable long-term availability, consistent quality, and continued technical support compared to the obsolete UUG2G470MRQ1MS.

Q: Are there compliance differences between the main part and substitute?

A: The substitute part carries RoHS3 compliance certification. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status. The substitute part meets current environmental and regulatory standards for electronic component manufacturing.
