URY2E330MHD Equivalent & Substitute Parts

Part Overview

The URY2E330MHD is a 33 µF, 250 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This part operates across -40°C to 105°C with a rated lifetime of 2000 hours at 105°C. The URY2E330MHD is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts maintain the core electrical specifications (33 µF capacitance, 250 V rating, ±20% tolerance) while offering variations in lifetime ratings, ripple current handling, physical dimensions, and product status.

Engineering Selection Recommendations

For Active Product Status (Recommended for New Designs):

URZ2E330MHD is the primary manufacturer-recommended substitute. It maintains identical lead spacing (0.295", 7.50mm) and similar physical footprint to the original URY2E330MHD while offering active product status and improved ripple current handling (250 mA @ 120 Hz, 400 mA @ 10 kHz). The reduced lifetime rating (1000 Hrs vs. 2000 Hrs @ 105°C) is offset by superior current capacity.

UCY2E330MHD3 and UCY2E330MPD provide extended lifetime ratings (12000 Hrs @ 105°C) with active status. These parts require different lead spacing (0.197", 5.00mm) and occupy smaller physical envelopes. Selection depends on PCB layout constraints and thermal cycling requirements.

For Extended Lifetime Applications:

UCY2E330MHD3 delivers 12-fold lifetime extension (12000 Hrs vs. 2000 Hrs @ 105°C) with significantly higher ripple current capacity (400 mA @ 120 Hz, 800 mA @ 10 kHz). Physical dimensions differ substantially; verify PCB footprint compatibility before selection.

For Cross-Manufacturer Compatibility:

EKMG251ELL330MK20S (Chemi-Con) and MAL214253393E3 (Vishay) provide active-status alternatives with equivalent electrical performance. Both maintain ROHS3 compliance and general-purpose application suitability. Lead spacing and physical dimensions differ; confirm PCB layout accommodation.

Parts to Avoid for New Designs:

UVZ2E330MHD carries "Not For New Designs" status despite active inventory. UPJ2E330MHD and UPS2E330MHD are obsolete; use only for legacy system maintenance where exact form-factor matching is critical.

Frequently Asked Questions (FAQ)

Q: Can URZ2E330MHD directly replace URY2E330MHD in existing designs?

A: Yes, with verification. Both parts share identical lead spacing (0.295", 7.50mm) and similar can diameter (0.709", 18.00mm). Height differs slightly (0.650" vs. 0.551"), requiring PCB clearance confirmation. Electrical specifications (33 µF, 250 V, ±20%) are identical. The reduced lifetime rating (1000 Hrs vs. 2000 Hrs @ 105°C) must be evaluated against application thermal cycling demands.

Q: What is the difference between UCY2E330MHD3 and UCY2E330MPD?

A: Both offer identical 12000-hour lifetime at 105°C and active product status. Primary differences are physical dimensions: UCY2E330MHD3 has 0.492" diameter (12.50mm) with 400 mA ripple current @ 120 Hz; UCY2E330MPD has 0.394" diameter (10.00mm) with 305 mA ripple current @ 120 Hz. Lead spacing is identical (0.197", 5.00mm) for both. Selection depends on available PCB space and ripple current requirements.

Q: Are Chemi-Con and Vishay parts electrically equivalent to Nichicon substitutes?

A: EKMG251ELL330MK20S (Chemi-Con) and MAL214253393E3 (Vishay) maintain the core electrical specifications (33 µF, 250 V, ±20% tolerance) and operating temperature range (-40°C to 105°C). Both are ROHS3 compliant and rated for general-purpose applications. Physical dimensions and lead spacing differ; verify PCB footprint compatibility. Ripple current performance varies; confirm suitability for your thermal and current-handling environment.

Q: Why does UVZ2E330MHD show "Not For New Designs" status?

A: UVZ2E330MHD is designated for legacy system support only. Although inventory is available (2863 pcs), Nichicon has discontinued this series for new product development. For new designs, select URZ2E330MHD, UCY2E330MHD3, UCY2E330MPD, or cross-manufacturer alternatives with active status.

Q: What lead spacing options are available?

A: Two lead spacing configurations exist: 0.295" (7.50mm) for URY2E330MHD, URZ2E330MHD, UPJ2E330MHD, and URZ2E330MHD6; and 0.197" (5.00mm) for UCY2E330MHD3, UCY2E330MPD, UPS2E330MHD, UVZ2E330MHD, EKMG251ELL330MK20S, and Vishay parts. Verify PCB hole spacing before substitution.

Q: How do ripple current ratings affect part selection?

A: Ripple current capacity determines thermal performance under AC current stress. Higher ripple current ratings (e.g., UCY2E330MHD3 at 400 mA @ 120 Hz, 800 mA @ 10 kHz) indicate superior thermal stability in high-frequency switching environments. Lower ratings (e.g., UVZ2E330MHD at 160 mA @ 120 Hz, 256 mA @ 10 kHz) suit lower-stress applications. Match ripple current to your circuit's actual AC current demands to prevent premature capacitor failure.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. All are suitable for applications requiring RoHS directive adherence.
