Substitute Part Grouping Explanation

Substitution of the UPW2F330MHD is determined by the following critical parameters:

Capacitance Value: 33 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: Minimum 315 V (equal or higher voltage rating acceptable)
Polarization: Polar (must match)
Mounting Type: Through Hole (must match)
Package / Case: Radial, Can (must match)
Lead Spacing: 0.295" (7.50mm) (must match for PCB compatibility)
Size / Dimension: 0.630" Dia (16.00mm) (must match for mechanical fit)
Operating Temperature Range: -40°C ~ 105°C (must match or exceed)
RoHS Compliance: ROHS3 Compliant (must match)

The UCS2G330MHD meets all substitution criteria with the following advantages: higher voltage rating (400 V vs. 315 V), extended lifetime (10000 Hrs @ 105°C vs. 8000 Hrs @ 105°C), improved ripple current handling, and active product status ensuring continued availability.

Engineering Selection Recommendations

The UCS2G330MHD is the manufacturer-recommended substitute for the obsolete UPW2F330MHD. Both components are ROHS3 compliant and manufactured by Nichicon, ensuring regulatory alignment and supply chain continuity.

The UCS2G330MHD provides direct functional replacement with enhanced specifications: the 400 V rating provides additional voltage margin over the original 315 V specification, and the extended 10000-hour lifetime at 105°C improves reliability compared to the 8000-hour rating of the UPW series. The reduced seated height (21.50mm vs. 25.00mm) offers improved PCB layout flexibility while maintaining identical lead spacing and diameter for mechanical compatibility.

Active product status of the UCS2G330MHD ensures long-term availability and supply security, eliminating the obsolescence risk associated with the UPW2F330MHD.

Frequently Asked Questions (FAQ)

Q: Can the UCS2G330MHD be used as a direct replacement for the UPW2F330MHD?

A: Yes. The UCS2G330MHD is the manufacturer-recommended substitute. Both components share identical capacitance (33 µF), tolerance (±20%), polarization (polar), mounting type (through hole), package style (radial can), lead spacing (7.50mm), and diameter (16.00mm). The UCS2G330MHD meets or exceeds all electrical and mechanical requirements of the UPW2F330MHD.

Q: What are the key differences between these two parts?

A: The UCS2G330MHD offers three primary improvements: higher voltage rating (400 V vs. 315 V), extended operational lifetime (10000 Hrs @ 105°C vs. 8000 Hrs @ 105°C), and superior ripple current handling capability. The UCS2G330MHD is also shorter (21.50mm vs. 25.00mm seated height), providing better PCB layout options.

Q: Will the UCS2G330MHD fit in the same PCB footprint as the UPW2F330MHD?

A: Yes. Both components have identical lead spacing (0.295" / 7.50mm) and diameter (0.630" / 16.00mm). The UCS2G330MHD is shorter, so it will fit within the same footprint with additional clearance above the component.

Q: Are both parts RoHS compliant?

A: Yes. Both the UPW2F330MHD and UCS2G330MHD are ROHS3 compliant.

Q: Why is the UPW2F330MHD obsolete?

A: The UPW series has been superseded by the UCS series, which offers improved performance characteristics and extended product lifecycle support. Nichicon recommends the UCS2G330MHD as the active replacement.

Q: What is the operating temperature range for both parts?

A: Both components operate across the identical temperature range of -40°C to 105°C.
