UPW2E330MHD1TO Equivalent & Substitute Parts

Part Overview

The UPW2E330MHD1TO is a 33 µF, 250 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has been superseded in the product lifecycle. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 7000 hours at 105°C. Finding equivalent or substitute parts is necessary for maintenance, repair, and legacy system support where the original component may no longer be readily available or where design improvements are desired.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPW2E330MHD1TO is determined by the following critical parameters:

• Capacitance: Must be 33 µF (exact match required)
• Voltage Rating: Must be ≥250 V (equal or higher voltage rating is acceptable)
• Tolerance: Must be ±20% or tighter
• Polarization: Must be Polar
• Package Type: Must be Radial, Can
• Mounting Type: Must be Through Hole
• Lead Spacing: Must be 0.197" (5.00 mm)
• Operating Temperature Range: Must support -40°C to 105°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status

All identified substitute parts meet these core electrical and mechanical compatibility criteria. Differences in lifetime rating, ripple current handling, and physical height are secondary considerations that do not prevent functional substitution but may affect performance characteristics in specific applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (250 V Rating)

UCS2E330MHD1TO and 860241178003 are direct electrical equivalents with identical voltage and capacitance ratings. Both parts are Active status and ROHS3 compliant. UCS2E330MHD1TO offers improved lifetime (10000 hours) and higher ripple current capability. The 860241178003 from Würth Elektronik provides an alternative manufacturer source with comparable performance. Both are suitable for direct replacement in existing designs.

UCY2E330MHD3TO is also a direct electrical equivalent with the highest lifetime rating (12000 hours) among 250 V options. This part carries REACH Affected status, which may require compliance verification depending on application jurisdiction.

Voltage Upgrade Option (400 V Rating)

UCY2G330MHD1TO operates at 400 V, providing overvoltage margin beyond the original 250 V specification. This part is suitable for applications where higher voltage headroom is beneficial or required. The increased voltage rating does not affect capacitance or tolerance specifications. This part is Active status and ROHS3 compliant but carries REACH Affected designation.

Product Status Consideration

All substitute parts carry Active product status, whereas the original UPW2E330MHD1TO is Not For New Designs. This transition supports long-term supply chain stability and design continuity.

Frequently Asked Questions (FAQ)

Q: Can UCS2E330MHD1TO directly replace UPW2E330MHD1TO?

A: Yes. Both parts share identical electrical specifications: 33 µF capacitance, 250 V voltage rating, ±20% tolerance, and -40°C to 105°C operating range. Lead spacing and mounting type are identical. UCS2E330MHD1TO offers extended lifetime (10000 hours versus 7000 hours) and higher ripple current ratings, making it a performance-equivalent or superior replacement.

Q: What is the difference between the Nichicon UCY2E330MHD3TO and UCY2G330MHD1TO?

A: Both are Nichicon UCY series parts with 33 µF capacitance and 12000-hour lifetime. The primary difference is voltage rating: UCY2E330MHD3TO is rated 250 V, while UCY2G330MHD1TO is rated 400 V. The 400 V part provides higher voltage margin but maintains the same capacitance and tolerance. Physical height differs slightly (0.846" versus 1.043").

Q: Can I use the 400 V rated UCY2G330MHD1TO in a 250 V circuit?

A: Yes. A higher voltage-rated capacitor is electrically compatible with lower voltage applications. The 400 V rating provides additional safety margin and does not degrade performance in 250 V circuits.

Q: Are there physical fitment concerns with substitute parts?

A: Lead spacing (0.197" / 5.00 mm) is identical across all substitutes, ensuring PCB compatibility. Physical height varies: UPW2E330MHD1TO is 1.063", UCS2E330MHD1TO and UCY2E330MHD3TO are 0.846", UCY2G330MHD1TO and 860241178003 are approximately 1.043". Verify clearance in confined spaces. Diameter is 0.492" (12.50 mm) for Nichicon parts and 0.512" (13.00 mm) for the Würth Elektronik part; verify mounting hole tolerance if critical.

Q: What is the significance of REACH Affected status?

A: REACH Affected indicates the part contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Compliance requirements depend on application jurisdiction and end-use classification. Consult regulatory requirements for your specific application.

Q: Which substitute offers the best reliability?

A: UCY2E330MHD3TO and UCY2G330MHD1TO both offer 12000-hour lifetime at 105°C, the highest among available options. UCS2E330MHD1TO and 860241178003 provide 10000-hour lifetime. Selection depends on application duty cycle and required service life.
