Substitute Part Grouping Explanation

Substitution eligibility for the UPW2D330MHD1TO is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance value: 33 µF (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Package type: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Operating temperature range: -40°C to 105°C (minimum requirement)
RoHS compliance: ROHS3 Compliant (required)

Secondary Considerations:

Voltage rating: Rated voltage must equal or exceed 200 V
Physical dimensions: Height and diameter must accommodate PCB layout constraints
Ripple current capability: Higher values indicate improved performance margin
Lifetime rating: Higher values indicate extended operational reliability

Three substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations

UPW2E330MHD1TO (Nichicon): This part maintains identical electrical and mechanical specifications to the main part with the exception of increased voltage rating (250 V vs. 200 V). It remains classified as "Not For New Designs," making it suitable only for direct replacement in existing applications. Voltage margin improvement provides additional safety in circuits operating near maximum ratings.

UCY2G330MHD1TO (Nichicon): This part offers the highest voltage rating (400 V) and extended lifetime (12000 Hrs @ 105°C vs. 7000 Hrs). It carries Active product status, making it the preferred choice for new designs and long-term availability. Significantly higher ripple current capability (385 mA @ 120 Hz, 770 mA @ 100 kHz) accommodates demanding applications. Physical dimensions remain compatible with standard PCB layouts.

860241178003 (Würth Elektronik): This part provides 250 V rating with 10000 Hrs lifetime and Active product status. It delivers higher ripple current performance (375 mA @ 120 Hz, 750 mA @ 100 kHz) compared to the main part. Diameter is marginally larger (0.512" vs. 0.492"), requiring verification of available PCB space. This option provides cross-manufacturer diversity for supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can UCY2G330MHD1TO be used as a direct replacement for UPW2D330MHD1TO?

A: Yes. The UCY2G330MHD1TO maintains identical capacitance (33 µF), tolerance (±20%), polarization, package type (Radial, Can), lead spacing (5.00 mm), and operating temperature range. The higher voltage rating (400 V vs. 200 V) and extended lifetime provide improved performance margins without affecting circuit compatibility.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the part has been superseded in the manufacturer's product lifecycle. While suitable for maintenance and legacy system repairs, it may face eventual discontinuation. For new designs, UCY2G330MHD1TO or 860241178003 are recommended due to their Active status and assured long-term availability.

Q: Does the slightly larger diameter of 860241178003 affect compatibility?

A: The 860241178003 has a diameter of 0.512" (13.00 mm) compared to 0.492" (12.50 mm) for the main part. PCB layout verification is required to confirm adequate clearance around the component footprint. Lead spacing and height remain compatible.

Q: Which substitute offers the best performance for high-ripple-current applications?

A: UCY2G330MHD1TO provides the highest ripple current ratings: 385 mA @ 120 Hz and 770 mA @ 100 kHz. This part is suitable for power supply filtering and other applications requiring significant AC current handling.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—UPW2E330MHD1TO, UCY2G330MHD1TO, and 860241178003—are ROHS3 Compliant, meeting environmental and regulatory requirements equivalent to the main part.
