EEU-ED2D330B Equivalent & Substitute Parts

Part Overview

The EEU-ED2D330B is a 33 µF, 200 V aluminum electrolytic capacitor in radial configuration manufactured by Panasonic Electronic Components. This component is rated for 8000 hours at 105°C and is designed for general-purpose applications requiring through-hole mounting. The part is currently active in production and ROHS3 compliant.

Equivalent and substitute parts are identified when electrical parameters (capacitance, voltage rating, tolerance, ripple current, and operating temperature range) and mechanical specifications (lead spacing, case size, and mounting type) align with the original component's functional requirements.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

Capacitance value: 33 µF (exact match required)
Voltage rating: 200 V or higher (equal or greater acceptable)
Tolerance: ±20% (exact match required)
Lead spacing: 0.197" (5.00 mm) (exact match required)
Case diameter: 0.394" (10.00 mm) (exact match required)
Mounting type: Through hole, radial configuration (exact match required)
Polarization: Polar (exact match required)

Parts are grouped into three categories:

Direct Equivalents: Identical electrical and mechanical specifications with different packaging or series designation.

Similar Parts: Meet all core electrical and mechanical requirements but may have enhanced performance characteristics (higher ripple current rating, extended lifetime, or expanded operating temperature range).

Upgrade Parts: Exceed the original specifications in one or more parameters (higher voltage rating or extended lifetime) while maintaining mechanical compatibility.

Engineering Selection Recommendations

Direct Equivalent (Preferred for Drop-In Replacement):

EEU-ED2D330 is the direct equivalent, differing only in packaging format (bulk versus tape & box) and height specification (0.787" versus 0.866"). Both are Panasonic ED series components with identical electrical ratings and active product status. Selection depends on procurement packaging requirements.

Nichicon UCS Series (Active, ROHS3 Compliant):

UCS2D330MPD1TD and UCS2D330MPD are functionally equivalent Nichicon alternatives. Both maintain 200 V, 33 µF specifications with 8000-hour lifetime ratings. The UCS series offers expanded operating temperature range (-40°C to 105°C versus -25°C to 105°C) and higher ripple current capability at 120 Hz (325 mA versus 260 mA). Both are ROHS3 compliant and active in production.

Nichicon UCY Series (Extended Lifetime, Active):

UCY2D330MPD1TD provides 12000-hour lifetime at 105°C, doubling the endurance of the original part while maintaining all other electrical specifications. Operating temperature range extends to -40°C. This part is ROHS3 compliant and active. REACH status is affected; verify compliance requirements for your application.

Upgrade Option (Higher Voltage Rating):

UCY2E330MPD1TD is rated at 250 V (versus 200 V) with 12000-hour lifetime. This part is suitable for applications requiring higher voltage margin or extended service life. Operating temperature range is -40°C to 105°C. REACH status is affected.

Obsolete Part (Not Recommended):

UCA2D330MHD is obsolete and should not be selected for new designs. Case diameter (0.492" versus 0.394") differs from the original specification, creating potential mechanical incompatibility.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2D330 replace EEU-ED2D330B directly?

A: Yes. Both parts are Panasonic ED series with identical electrical specifications (33 µF, 200 V, ±20%, 8000 Hrs @ 105°C). The difference is packaging format and height. EEU-ED2D330 is supplied in bulk packaging with 0.787" height versus tape & box with 0.866" height for EEU-ED2D330B. Verify PCB layout clearance before substitution.

Q: What is the difference between Panasonic ED and EE series?

A: Both ED and EE series meet the core electrical requirements (33 µF, 200 V, ±20%). The EE series (EEU-EE2D330) offers higher ripple current ratings (322 mA @ 120 Hz and 920 mA @ 100 kHz versus 260 mA and 650 mA). Select EE series if your application requires higher ripple current handling.

Q: Can I use a Nichicon part instead of Panasonic?

A: Yes, provided electrical and mechanical specifications align. UCS2D330MPD and UCS2D330MPD1TD are direct functional equivalents. Both are ROHS3 compliant, active in production, and maintain 200 V, 33 µF ratings. Nichicon parts offer expanded operating temperature range (-40°C to 105°C).

Q: What is the advantage of UCY2D330MPD1TD over UCS2D330MPD1TD?

A: UCY2D330MPD1TD extends lifetime to 12000 hours at 105°C (versus 8000 hours). All other electrical specifications remain identical. Select UCY series for applications requiring extended service life or higher reliability margins.

Q: Can I use UCY2E330MPD1TD (250 V) in place of the 200 V original?

A: Yes. Higher voltage rating provides additional safety margin and is mechanically compatible. UCY2E330MPD1TD also offers 12000-hour lifetime. This is an upgrade option suitable for applications where voltage headroom is beneficial. Verify REACH compliance requirements for your region.

Q: Why is UCA2D330MHD listed as obsolete?

A: UCA2D330MHD is no longer in active production. Additionally, case diameter (0.492" versus 0.394") differs from the original specification, creating potential PCB layout incompatibility. Do not select for new designs.

Q: What packaging options are available?

A: EEU-ED2D330B is supplied in tape & box. Direct equivalent EEU-ED2D330 is available in bulk. Nichicon UCS and UCY series are available in cut tape (CT) or bulk packaging depending on part number suffix. Verify packaging requirements for your assembly process.

Q: Are all substitute parts ROHS3 compliant?

A: All active parts listed are ROHS3 compliant. UCA2D330MHD (obsolete) is also ROHS3 compliant but should not be selected due to obsolescence and mechanical incompatibility.
