EEU-ED2C820 Equivalent & Substitute Parts

Part Overview

The EEU-ED2C820 is an 82 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This capacitor is rated for 10,000 hours at 105°C and is designed for general-purpose applications requiring stable capacitance and ripple current handling. The part is currently active in production with full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs without performance degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-ED2C820 is determined by the following critical parameters:

Capacitance Value: Must be 82 µF
Voltage Rating: Must be 160 V or higher
Tolerance: Must be ±20% or tighter
Polarization: Must be Polar
Lead Spacing: Must be 0.197" (5.00 mm)
Package Type: Must be Radial, Can
Mounting Type: Must be Through Hole
Operating Temperature Range: Must support -25°C ~ 105°C minimum
Lifetime Rating: Must be 10,000 Hrs @ 105°C or greater

The EEU-EE2C820 meets all substitution criteria. Both parts share identical electrical specifications (capacitance, voltage, tolerance, temperature range, and lifetime rating) and mechanical compatibility (lead spacing, package type, mounting configuration). Differences in ripple current ratings and physical height do not preclude substitution when the application circuit design accommodates the specified ripple current performance of the substitute part.

Engineering Selection Recommendations

Both the EEU-ED2C820 and EEU-EE2C820 are active production parts with identical RoHS3 and REACH compliance status. Selection between these parts should be based on:

PCB Layout Constraints: The EEU-EE2C820 has a maximum seated height of 1.063" (27.00 mm) compared to 0.984" (25.00 mm) for the EEU-ED2C820. Verify available vertical clearance on the PCB assembly.
Ripple Current Requirements: The EEU-EE2C820 provides higher ripple current capacity (518 mA @ 120 Hz and 1.48 A @ 100 kHz) compared to the EEU-ED2C820 (424 mA @ 120 Hz and 1.06 A @ 100 kHz). Select based on circuit ripple current demands.
Inventory Availability: The EEU-EE2C820 has 2,025 pieces in stock versus 874 pieces for the EEU-ED2C820.

Both parts satisfy the core electrical and mechanical requirements for direct substitution in 82 µF, 160 V general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the EEU-EE2C820 replace the EEU-ED2C820 in existing designs?

A: Yes. Both parts have identical capacitance (82 µF), voltage rating (160 V), tolerance (±20%), operating temperature range (-25°C ~ 105°C), lifetime rating (10,000 Hrs @ 105°C), lead spacing (5.00 mm), and package type (Radial, Can). Verify that the increased height (27.00 mm vs. 25.00 mm) and higher ripple current rating do not conflict with PCB layout or circuit requirements.

Q: What are the key differences between these two parts?

A: The primary differences are physical height and ripple current performance. The EEU-EE2C820 is 2.00 mm taller and provides higher ripple current capacity at both low frequency (518 mA @ 120 Hz vs. 424 mA) and high frequency (1.48 A @ 100 kHz vs. 1.06 A).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the EEU-ED2C820 and EEU-EE2C820 are RoHS3 compliant and REACH unaffected.

Q: What mounting configuration do these capacitors use?

A: Both parts are through-hole mounted radial capacitors with 5.00 mm lead spacing, suitable for PCB insertion and wave or reflow soldering processes.

Q: Can I use the EEU-EE2C820 if my circuit requires lower ripple current handling?

A: Yes. The EEU-EE2C820 has higher ripple current ratings than the EEU-ED2C820, so it will perform adequately in applications requiring lower ripple current. The capacitor will operate within specification.
