Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

UPW2C330MHD1TO: Nichicon UPW series provides identical 160 V rating with extended 7000-hour lifetime and reduced height (22.00 mm vs. 27.00 mm). Suitable for direct replacement with improved reliability margin.
UPJ2C330MHD1TO: Nichicon UPJ series matches all electrical specifications and physical dimensions. Parametric equivalent from alternative Nichicon product line.

Voltage Upgrade Options (Higher Voltage Rating):

UPW2D330MHD1TO: 200 V rating provides 25% voltage margin over the original 160 V specification with 7000-hour lifetime. Maintains identical physical footprint.
UPW2E330MHD1TO: 250 V rating provides 56% voltage margin with 7000-hour lifetime. Identical physical dimensions to main part.
UCY2G330MHD1TO: 400 V rating with 12000-hour lifetime (2.4× longer than original). Active product status ensures long-term availability. Slightly reduced height (26.50 mm) maintains PCB compatibility.

Alternative Manufacturer:

860241178003 (Würth Elektronik WCAP-AT1H): 250 V, 10000-hour lifetime with Active product status. Case diameter increases to 0.512" (13.00 mm); verify PCB layout clearance before selection.

Recommendation Basis:

For new designs, select UCY2G330MHD1TO (Active status, extended lifetime, higher voltage margin)
For direct replacement in existing designs, select UPW2C330MHD1TO (same voltage, improved lifetime, reduced height)
For applications requiring alternative manufacturer qualification, select 860241178003 (Active status, verified performance)

Frequently Asked Questions (FAQ)

Q: Can UPW2C330MHD1TO be used as a direct replacement for UPM2C330MHD1TO? A: Yes. Both parts share identical capacitance (33 µF), voltage rating (160 V), tolerance (±20%), and lead spacing (5.00 mm). The UPW series offers extended lifetime (7000 hrs vs. 5000 hrs) and reduced height (22.00 mm vs. 27.00 mm), making it a superior direct replacement.

Q: What is the advantage of selecting UCY2G330MHD1TO over the original UPM2C330MHD1TO? A: The UCY2G330MHD1TO provides three key improvements: (1) 400 V voltage rating vs. 160 V, offering 2.5× voltage margin; (2) 12000-hour lifetime vs. 5000 hours, providing 2.4× extended service life; (3) Active product status ensures continued availability and supply chain stability.

Q: Are there physical compatibility concerns when substituting with higher voltage ratings? A: Lead spacing (5.00 mm) and case diameter (12.50 mm) remain constant across all Nichicon substitutes, ensuring PCB footprint compatibility. Height variations are minimal (20.00 mm to 27.00 mm range). The Würth Elektronik part (860241178003) has a slightly larger case diameter (13.00 mm); verify PCB layout clearance.

Q: Why is UPM2C330MHD1TO marked "Not For New Designs"? A: This designation indicates the part has been superseded by improved alternatives within Nichicon's product portfolio. New designs should utilize active-status parts such as UCY2G330MHD1TO to ensure long-term supply availability and access to manufacturing improvements.

Q: Can parts with different voltage ratings be used interchangeably? A: Yes, within the constraints of circuit design. A capacitor with higher voltage rating can replace one with lower voltage rating, provided the circuit does not exceed the original voltage specification. Higher voltage ratings provide additional safety margin but may increase component cost and size.

Q: What is the significance of the "Cut Tape (CT)" packaging specification? A: Cut Tape packaging indicates the component is supplied on continuous tape that is cut to length for automated pick-and-place assembly. This is standard for high-volume manufacturing. Verify packaging compatibility with your assembly equipment before procurement.

Q: Are all listed substitutes RoHS3 compliant? A: Yes. All parts listed—UPM2C330MHD1TO, UPW series variants, UPJ2C330MHD1TO, UCY2G330MHD1TO, and 860241178003—are ROHS3 compliant and suitable for applications requiring lead-free construction.
