UPS2E330MHD Equivalent & Substitute Parts

Part Overview

The UPS2E330MHD is a 33 µF, 250 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as obsolete, with a rated lifetime of 3000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts with improved specifications or active product status are necessary for new designs and ongoing production requirements. Substitute parts maintain the core electrical characteristics (33 µF capacitance, 250 V rating, ±20% tolerance) while offering extended operational lifetimes, improved ripple current handling, or higher voltage ratings for enhanced circuit reliability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Electrical Compatibility: Capacitance (33 µF), voltage rating (250 V), and tolerance (±20%) must match exactly. Operating temperature range (-40°C ~ 105°C) and polarization (polar) must be identical.

Mechanical Compatibility: Lead spacing (0.197" / 5.00 mm) and mounting type (through hole radial) must match to ensure PCB footprint compatibility. Case diameter and height variations are acceptable if they do not exceed board space constraints.

Performance Enhancement: Substitute parts may offer extended lifetime ratings (5000 Hrs, 10000 Hrs, or 12000 Hrs @ 105°C) or improved ripple current specifications without compromising the core electrical parameters.

Voltage Upgrade Path: Parts with higher voltage ratings (400 V, 420 V, 450 V) are classified as upgrades and provide additional safety margin in circuits where voltage headroom is available.

Product Status Consideration: Active and not-for-new-designs parts are preferred over obsolete classifications for ongoing production.

Engineering Selection Recommendations

Primary Direct Substitute (Same Voltage, Extended Lifetime): UCY2E330MHD3 and UCS2E330MHD are the preferred replacements for UPS2E330MHD. Both maintain 250 V rating and 33 µF capacitance with identical lead spacing (0.197" / 5.00 mm) and case diameter (0.492" / 12.50 mm). UCY2E330MHD3 offers 12000 hours lifetime with active product status and improved ripple current specifications (400 mA @ 120 Hz, 800 mA @ 100 kHz). UCS2E330MHD provides 10000 hours lifetime with active product status and equivalent ripple current performance. Both are ROHS3 compliant and suitable for direct PCB substitution with reduced height (0.846" vs. 1.063"), providing additional board space margin.

Compact Form Factor Alternative: UCY2E330MPD maintains electrical specifications identical to the primary substitutes but with reduced case diameter (0.394" / 10.00 mm). This part is suitable for space-constrained applications where the smaller footprint is advantageous. Product status is active with 12000 hours lifetime rating.

Voltage Upgrade Options: UCY2G330MHD (400 V) and Rubycon 420BXW33MEFR12.5X25 / 450BXW33MEFR12.5X25 (420 V / 450 V) provide higher voltage ratings while maintaining 33 µF capacitance and 0.197" lead spacing. These upgrades are applicable in circuits where voltage headroom enhancement is required. All three parts offer 12000 hours lifetime and active product status. The Rubycon parts maintain the original height specification (1.063" / 27.00 mm), matching the UPS2E330MHD mechanical envelope.

Legacy Compatibility (Different Lead Spacing): UPJ2E330MHD, URZ2E330MHD, URZ2E330MHD6, and UVZ2E330MHD maintain 33 µF / 250 V specifications but feature different lead spacing (0.295" / 7.50 mm for UPJ and URZ series, 0.197" / 5.00 mm for UVZ). These parts require PCB redesign for lead spacing accommodation and are not recommended for direct footprint substitution. UVZ2E330MHD is classified as not-for-new-designs and should be avoided in new product development.

Frequently Asked Questions (FAQ)

Q: Can UCY2E330MHD3 be used as a direct replacement for UPS2E330MHD without PCB modification?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and electrical specifications (33 µF, 250 V, ±20% tolerance). The reduced height of UCY2E330MHD3 (0.846" vs. 1.063") provides additional clearance and does not require PCB changes. Electrical performance is improved with 12000 hours lifetime and higher ripple current ratings.

Q: What is the difference between UCY2E330MHD3 and UCS2E330MHD?

A: Both parts are direct substitutes with identical mechanical compatibility and electrical ratings. The primary difference is lifetime specification: UCY2E330MHD3 offers 12000 hours at 105°C, while UCS2E330MHD offers 10000 hours. Both feature 400 mA ripple current at 120 Hz and 800 mA at 100 kHz. Selection between these parts depends on application lifetime requirements and inventory availability.

Q: Can I use URZ2E330MHD or UPJ2E330MHD as replacements?

A: These parts maintain the same electrical specifications (33 µF, 250 V) but feature different lead spacing (0.295" / 7.50 mm vs. 0.197" / 5.00 mm on the original). Direct PCB substitution is not possible without redesign. These parts are suitable only for new board layouts where lead spacing can be accommodated.

Q: What are the advantages of upgrading to UCY2G330MHD or the Rubycon 420/450 V parts?

A: Voltage upgrades provide increased safety margin in circuits operating near the 250 V rating. UCY2G330MHD (400 V) and Rubycon parts (420 V / 450 V) maintain 33 µF capacitance and 0.197" lead spacing for direct PCB compatibility. All three offer 12000 hours lifetime and active product status. Voltage upgrades are recommended when circuit design permits and component cost is not a limiting factor.

Q: Is UCY2E330MPD suitable for my application?

A: UCY2E330MPD is electrically equivalent to UCY2E330MHD3 and UCS2E330MHD with identical 250 V rating, 33 µF capacitance, and 12000 hours lifetime. The primary difference is reduced case diameter (0.394" / 10.00 mm vs. 0.492" / 12.50 mm). This part is suitable only if board layout accommodates the smaller footprint. Lead spacing remains identical (0.197" / 5.00 mm), ensuring PCB compatibility.

Q: Why is UVZ2E330MHD classified as not-for-new-designs?

A: UVZ2E330MHD offers only 2000 hours lifetime at 105°C, which is significantly lower than active alternatives. While the part maintains 250 V rating and 0.197" lead spacing for direct substitution, its reduced lifetime specification makes it unsuitable for new product development. This classification indicates that Nichicon recommends transitioning to newer series for improved reliability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements for electronic component manufacturing and assembly.
