EEU-EE2G820 Equivalent & Substitute Parts

Part Overview

The EEU-EE2G820 is an 82 µF, 400 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part operates across -25°C to 105°C with a rated lifetime of 10,000 hours at 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

Capacitance: 82 µF (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Case Diameter: 0.709" (18.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Compatibility Parameters:

Voltage Rating: 400 V minimum (equal or higher acceptable)
Operating Temperature Range: -25°C to 105°C minimum (equal or wider acceptable)
RoHS3 Compliance: Required

Height Variation Tolerance:

Maximum seated height variance: ±0.256" (±6.50 mm) from original 1.319" (34.60 mm)

Substitute parts are grouped into two categories: similar parts (matching all primary parameters at original voltage) and upgrade parts (matching all primary parameters with higher voltage ratings or improved specifications).

Engineering Selection Recommendations

Direct Replacement (Same Voltage, Active Status):

UPT2G820MHD (Nichicon) is the preferred direct replacement. It maintains 400 V rating, matches all primary mechanical parameters, and is in active production status. Height is within acceptable tolerance at 1.299" (33.00 mm).

Voltage-Upgraded Alternatives (Higher Voltage Rating, Active Status):

EKXJ421ELL820MMN3S (Chemi-Con, 420 V) and EKXJ451ELL820MMN3S (Chemi-Con, 450 V) provide higher voltage margins with improved lifetime specifications (12,000 hours vs. 10,000 hours). Both are AEC-Q200 rated and in active production.
UCY2W820MHD6 (Nichicon, 450 V) and UCYW6820MHD6 (Nichicon, 420 V) offer equivalent voltage upgrades with active status and extended operating temperature range (-40°C to 105°C).

Compact Alternative (Reduced Height):

LDQ2G820MERYGA (Nichicon) provides a compact form factor at 0.787" (20.00 mm) height with matching 400 V rating. This part is suitable only for applications where reduced height is required, as its 2,000-hour lifetime is significantly lower than the original specification.

Obsolete Panasonic Alternative:

EEU-ED2G820 (Panasonic) maintains identical electrical specifications but is also obsolete and has increased height (1.575" vs. 1.319"), making it unsuitable for space-constrained designs.

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. A capacitor rated at 420 V or 450 V is electrically compatible with a 400 V application. Higher voltage ratings provide additional safety margin and do not degrade performance in lower-voltage circuits.

Q: What is the impact of different case heights on substitution? A: Case height affects PCB layout and mechanical fit. The original EEU-EE2G820 is 1.319" (34.60 mm) tall. Substitutes with heights of 1.299" (33.00 mm) or 1.575" (40.00 mm) may require layout verification. The compact LDQ2G820MERYGA at 0.787" (20.00 mm) is suitable only for designs with height constraints.

Q: Does lifetime rating affect substitution eligibility? A: Lifetime rating does not disqualify a substitute. However, parts with lower lifetime specifications (such as LDQ2G820MERYGA at 2,000 hours) should be selected only when application duty cycle permits. For general-purpose applications requiring the original 10,000-hour specification, select parts rated at 10,000 hours or higher.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant, matching the original part's environmental compliance status.

Q: What is the difference between similar and upgrade substitutes? A: Similar substitutes maintain the original 400 V voltage rating. Upgrade substitutes provide higher voltage ratings (420 V or 450 V) with improved specifications such as extended lifetime and wider operating temperature ranges.
