UCS2G470MHD Equivalent & Substitute Parts

Part Overview

The UCS2G470MHD is a 47 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 10,000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering in power supply circuits. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UCS2G470MHD is determined by the following critical parameters:

• Capacitance Value: Must be 47 µF (±20% tolerance band)
• Voltage Rating: Minimum 400 V (equal or higher voltage rating acceptable)
• Polarization: Polar (electrolytic type)
• Mounting Type: Through Hole radial configuration
• Lead Spacing: 0.295" (7.50 mm) pitch
• Can Diameter: 0.630" (16.00 mm)
• Height Constraint: Maximum seated height must not exceed available board clearance; minor height variations within mechanical tolerance are acceptable
• Operating Temperature: -40°C ~ 105°C minimum range
• Compliance: RoHS3 compliant, REACH unaffected

The substitute part 450BXW47MEFR16X25 meets all critical electrical and mechanical parameters. The rated voltage is increased to 450 V (higher than the 400 V requirement), providing enhanced voltage margin. The lifetime rating is upgraded to 12,000 hours at 105°C. Physical dimensions remain compatible with the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both the UCS2G470MHD and 450BXW47MEFR16X25 maintain Active product status with full regulatory compliance. The substitute part offers equivalent electrical performance with enhanced voltage margin (450 V vs. 400 V) and extended thermal lifetime (12,000 hours vs. 10,000 hours at 105°C). Both components are RoHS3 compliant and REACH unaffected. The mechanical compatibility is confirmed across all critical dimensions, with a maximum height difference of 0.020 inches (0.50 mm), which remains within standard PCB clearance tolerances for radial through-hole components. Selection between these parts depends on supply availability and application-specific voltage margin requirements.

Frequently Asked Questions (FAQ)

Q: Can the 450BXW47MEFR16X25 be used as a direct replacement for the UCS2G470MHD?

A: Yes. Both parts share identical capacitance (47 µF), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lead spacing (7.50 mm), can diameter (16.00 mm), and mounting configuration (through-hole radial). The substitute has a higher voltage rating (450 V vs. 400 V) and improved lifetime rating (12,000 hours vs. 10,000 hours at 105°C). The height difference of 0.020 inches is within standard PCB clearance tolerances.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by: capacitance value (47 µF), voltage rating (minimum 400 V), polarization type (polar), mounting configuration (through-hole radial), lead spacing (7.50 mm), can diameter (16.00 mm), operating temperature range (-40°C ~ 105°C), and compliance certifications (RoHS3, REACH unaffected).

Q: Does the higher voltage rating of the substitute part affect circuit operation?

A: No. A higher voltage rating does not negatively affect circuit operation. The 450 V rating of the substitute provides additional voltage margin and is fully compatible with circuits designed for 400 V operation.

Q: Are there any mechanical compatibility concerns with the 0.020-inch height difference?

A: No. The height difference of 0.020 inches (0.50 mm) between the two parts is negligible for through-hole radial capacitors and remains within standard PCB design clearances. Both components use identical lead spacing and can diameter.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the UCS2G470MHD and 450BXW47MEFR16X25 are RoHS3 compliant and REACH unaffected, meeting identical regulatory requirements for industrial and commercial applications.
