Nichicon UAS2G330MHD Equivalent & Substitute Parts

Part Overview

The Nichicon UAS2G330MHD is a 33 µF, 400 V aluminum electrolytic capacitor in radial, can package rated for 2000 hours at 105°C. This component is classified as Active product status and is suitable for general purpose applications. Equivalent and substitute parts are identified when electrical specifications (capacitance, voltage rating, tolerance, operating temperature range) and mechanical parameters (package type, lead spacing, mounting configuration) align with the original part, enabling direct replacement in circuit designs.

Key Parameters

Parameter	Value
Capacitance	33 µF
Voltage Rating	400 V
Tolerance	±20%
Operating Temperature Range	-40°C ~ 105°C
Package Type	Radial, Can
Lead Spacing	0.295" (7.50 mm)
Mounting Type	Through Hole
Polarization	Polar
Size / Dimension	0.630" Dia (16.00 mm)

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

Electrical Specifications: Capacitance (33 µF), voltage rating (400 V), and tolerance (±20%) must be identical
Operating Temperature Range: Must encompass or match the original range (-40°C ~ 105°C minimum)
Package Configuration: Radial, can package with identical lead spacing (0.295" / 7.50 mm) and through-hole mounting
Physical Dimensions: Can diameter (0.630" / 16.00 mm) and height must be compatible with PCB layout constraints
Polarization: Polar configuration must be maintained

All substitute parts listed meet these core requirements. Variations in lifetime rating, ripple current capacity, and manufacturer series do not preclude substitution when the above parameters align.

Chemi-Con EKXG401ELL330ML20S: Cross-manufacturer equivalent with 10000-hour lifetime rating and ROHS3 compliance. Lowest profile option at 0.787" (20.00 mm) height. REACH unaffected status. Suitable for applications requiring compact vertical clearance.

Chemi-Con EGXF401ELL330ML20S: Automotive-grade substitute with AEC-Q200 certification and extended operating temperature range (-40°C ~ 125°C). Rated for 3000 hours at 125°C, providing thermal margin for high-temperature environments. Recommended for automotive and industrial applications requiring enhanced temperature performance.

Frequently Asked Questions (FAQ)

Q: Can UCS2G330MHD replace UAS2G330MHD directly?

A: Yes. Both parts share identical electrical specifications (33 µF, 400 V, ±20% tolerance), operating temperature range (-40°C ~ 105°C), and mechanical configuration (radial, can, 0.295" lead spacing, 16.00 mm diameter). The UCS variant offers extended lifetime (10000 vs. 2000 hours at 105°C) and improved ripple current performance without compromising compatibility.

Q: What is the height difference between substitute parts?

A: UAS2G330MHD measures 0.866" (22.00 mm). UCS2G330MHD and UCY2G330MHD3 measure 0.846" (21.50 mm). EKXG401ELL330ML20S measures 0.787" (20.00 mm). EGXF401ELL330ML20S measures 0.846" (21.50 mm). Verify PCB clearance requirements before selecting the lowest-profile option.
