UVZ2G3R3MPH Equivalent & Substitute Parts

Part Overview

The UVZ2G3R3MPH is a 3.3 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 2000 hours at 105°C, serving general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution for the UVZ2G3R3MPH is determined by strict equivalence across the following parameters: capacitance value (3.3 µF), voltage rating (400 V), tolerance (±20%), operating temperature range (-40°C to 105°C), polarization (polar), package type (radial, can), and mounting type (through hole). Lead spacing (5.00 mm) and physical dimensions must remain compatible with the original PCB layout. Lifetime rating of 2000 hours at 105°C establishes the minimum thermal endurance requirement.

Two categories of substitutes are identified:

Direct Manufacturer Substitutes: Parts from Nichicon within the same UVZ series that maintain identical electrical and mechanical specifications while offering improved product status or compliance certifications.

Similar Manufacturer Substitutes: Parts from alternative manufacturers (Cornell Dubilier Electronics) that match all critical electrical parameters and physical dimensions, enabling cross-manufacturer compatibility.

Engineering Selection Recommendations

UVZ2G3R3MPD (Direct Manufacturer Substitute): This Nichicon part provides direct electrical and mechanical equivalence to the UVZ2G3R3MPH. The primary advantage is ROHS3 compliance, addressing regulatory requirements for new production environments. Product status is "Not For New Designs," indicating this part remains available for legacy system support and repair applications. Identical ripple current specifications (38 mA @ 120 Hz, 60.8 mA @ 10 kHz) ensure drop-in compatibility. This substitute is preferred for applications requiring manufacturer continuity and compliance certification.

SEK3R3M400ST (Similar Manufacturer Substitute): This Cornell Dubilier Electronics part maintains all critical electrical parameters (3.3 µF, 400 V, ±20%, 2000 Hrs @ 105°C) and physical dimensions (5.00 mm lead spacing, 10.00 mm diameter). Active product status provides long-term availability and supply chain stability. ROHS3 compliance is confirmed. The height dimension (13.00 mm vs. 12.50 mm) represents a 0.5 mm increase; PCB layout verification is required to confirm clearance compatibility. Higher ripple current ratings (47 mA @ 120 Hz, 84.6 mA @ 10 kHz) provide additional thermal margin in ripple-intensive applications. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and PCB height clearance permits the dimensional variance.

Frequently Asked Questions (FAQ)

Q: Can UVZ2G3R3MPD be used as a direct replacement for UVZ2G3R3MPH?

A: Yes. Both parts share identical capacitance (3.3 µF), voltage rating (400 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lead spacing (5.00 mm), and package dimensions. Electrical performance and PCB footprint compatibility are maintained. The primary difference is improved RoHS3 compliance in the UVZ2G3R3MPD.

Q: What is the height difference between UVZ2G3R3MPH and SEK3R3M400ST?

A: The UVZ2G3R3MPH has a maximum seated height of 0.492" (12.50 mm), while the SEK3R3M400ST measures 0.512" (13.00 mm). This 0.5 mm difference must be evaluated against available PCB clearance to the next assembly level or enclosure.

Q: Are ripple current specifications interchangeable between these parts?

A: No. The UVZ2G3R3MPH and UVZ2G3R3MPD both specify 38 mA @ 120 Hz and 60.8 mA @ 10 kHz. The SEK3R3M400ST specifies higher ripple currents (47 mA @ 120 Hz, 84.6 mA @ 10 kHz). In applications with high ripple current demands, the SEK3R3M400ST provides additional thermal margin. In current-limited applications, either part is acceptable.

Q: Why is the UVZ2G3R3MPH marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Nichicon. The UVZ2G3R3MPD (Not For New Designs) and SEK3R3M400ST (Active) represent current alternatives for ongoing supply and new production requirements.

Q: Is RoHS compliance required for my application?

A: The UVZ2G3R3MPH is RoHS non-compliant. Both substitute parts (UVZ2G3R3MPD and SEK3R3M400ST) are ROHS3 compliant. If regulatory or customer requirements mandate RoHS compliance, either substitute is suitable.

Q: Can I use SEK3R3M400ST in a legacy system originally designed for UVZ2G3R3MPH?

A: Yes, provided PCB layout accommodates the 0.5 mm height increase (13.00 mm vs. 12.50 mm). All electrical parameters, lead spacing, and diameter match the original specification. Cross-manufacturer substitution is electrically valid.
