UPB2V331MRD Equivalent & Substitute Parts

Part Overview

The UPB2V331MRD is a 330 µF, 350 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for 5000 hours at 105°C and is designed for general purpose applications. The product status is obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UPB2V331MRD is determined by the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Equal to or greater than 350 V
• Package type: Radial, can with through-hole mounting
• Physical dimensions: Lead spacing 0.492" (12.50 mm), diameter 0.984" (25.00 mm), height 2.047" (52.00 mm)
• Operating temperature range: -25°C ~ 105°C (minimum requirement)
• Lifetime rating: 5000 Hrs @ 105°C (minimum requirement)

The UPT2G331MRD qualifies as a direct substitute based on matching capacitance, tolerance, package configuration, physical dimensions, temperature range, and lifetime specifications. The higher voltage rating (400 V versus 350 V) provides additional design margin without affecting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The UPT2G331MRD is a direct substitute for the UPB2V331MRD. Both components are obsolete products from Nichicon with identical capacitance, tolerance, package configuration, and physical dimensions. The UPT2G331MRD features a higher voltage rating (400 V versus 350 V), which provides additional design margin and does not introduce compatibility issues in applications designed for the original 350 V specification.

The UPT2G331MRD is RoHS3 compliant, whereas compliance information for the UPB2V331MRD is not provided. Both parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the UPT2G331MRD replace the UPB2V331MRD in existing designs?

A: Yes. The UPT2G331MRD is a direct substitute. Both parts share identical capacitance (330 µF), tolerance (±20%), package type (radial, can), physical dimensions, lead spacing, and thermal specifications. The higher voltage rating of the substitute part does not affect compatibility.

Q: What is the difference between the two parts?

A: The primary differences are voltage rating (400 V versus 350 V) and ripple current specifications. The UPT2G331MRD provides higher ripple current capability at low frequency (1.4 A @ 120 Hz versus 1.05 A). Both parts are rated for identical lifetime (5000 Hrs @ 105°C) and operating temperature range (-25°C ~ 105°C).

Q: Are there any compliance differences between these parts?

A: The UPT2G331MRD is confirmed RoHS3 compliant. Both parts are REACH unaffected and classified as EAR99 for export purposes.

Q: Will the UPT2G331MRD fit the same PCB footprint?

A: Yes. Both parts have identical physical dimensions, lead spacing (0.492" / 12.50 mm), diameter (0.984" / 25.00 mm), and maximum seated height (2.047" / 52.00 mm). No PCB layout modifications are required.

Q: Why are both parts listed as obsolete?

A: Both the UPB2V331MRD and UPT2G331MRD are obsolete products from Nichicon. Obsolete status indicates these parts are no longer in active production. Substitute identification is necessary for system maintenance and component procurement planning.
