EEU-EB2C680S Equivalent & Substitute Parts

Part Overview

The EEU-EB2C680S is a 68 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 5000 hours at 105°C and is designed for general-purpose applications requiring polar capacitance in through-hole mounting configurations. The part is ROHS3 compliant and currently in active production status with 786 units in stock.

Substitute parts are identified when design requirements allow for higher voltage ratings, extended operational lifetime, or improved ripple current handling while maintaining the same capacitance value and core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the EEU-EB2C680S are determined by the following criteria:

Upgrade Substitutes maintain identical capacitance (68 µF), tolerance (±20%), and physical dimensions while offering one or more of the following improvements:

• Higher voltage rating (200 V or 250 V vs. 160 V)
• Extended operational lifetime (10000 Hrs vs. 5000 Hrs @ 105°C)
• Increased ripple current capacity at high frequency (1 A @ 100 kHz vs. 750 mA @ 100 kHz)

Similar Substitutes maintain identical capacitance and voltage rating but differ in physical dimensions, lead spacing, or operational lifetime. These are suitable only when PCB layout accommodates the different form factor.

All substitute parts listed are Panasonic Electronic Components products with ROHS3 compliance and active production status.

Parameter Comparison

Engineering Selection Recommendations

Direct Upgrade Path (Same Physical Footprint):

EEU-EB2D680S provides a voltage upgrade from 160 V to 200 V while maintaining identical physical dimensions and lead spacing. This substitution is suitable for applications where higher voltage margin is required without PCB redesign.

EEU-ED2D680S and EEU-ED2E680S offer both voltage upgrades and extended lifetime (10000 Hrs vs. 5000 Hrs). These parts are physically compatible with the main part's lead spacing (7.50mm) but feature reduced height (0.787" vs. 0.866"), which may provide additional PCB clearance. Both parts support higher ripple current (1 A @ 100 kHz vs. 750 mA @ 100 kHz).

Alternative Form Factor (Reduced Dimensions):

EEU-ED2C680 and EEU-EE2C680 maintain the 160 V rating and 68 µF capacitance but feature smaller physical dimensions (0.492" diameter, 5.00mm lead spacing). These parts are suitable only when PCB layout has been designed to accommodate the reduced footprint. EEU-EE2C680 provides the highest ripple current capacity (1.35 A @ 100 kHz) among all listed alternatives.

All substitute parts maintain ROHS3 compliance, active production status, and Panasonic Electronic Components manufacturing.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB2D680S be used as a direct replacement for EEU-EB2C680S?

A: Yes. Both parts share identical physical dimensions, lead spacing (7.50mm), and capacitance (68 µF). The primary difference is the voltage rating: EEU-EB2D680S is rated for 200 V compared to 160 V. This substitution is suitable when higher voltage margin is required. Both parts maintain 5000-hour lifetime at 105°C.

Q: What is the advantage of EEU-ED2D680S over EEU-EB2D680S?

A: EEU-ED2D680S extends the operational lifetime from 5000 hours to 10000 hours at 105°C and increases ripple current capacity from 750 mA to 1 A at 100 kHz. The height is reduced from 0.866" to 0.787", which may provide additional PCB clearance. Lead spacing and voltage rating remain identical.

Q: Can EEU-ED2C680 be used in place of EEU-EB2C680S?

A: EEU-ED2C680 maintains the same capacitance (68 µF) and voltage rating (160 V) but features different physical dimensions: 0.492" diameter and 5.00mm lead spacing compared to 0.630" diameter and 7.50mm lead spacing. This substitution requires PCB redesign and is suitable only when the smaller footprint is accommodated in the circuit layout.

Q: Which substitute part offers the highest ripple current capacity?

A: EEU-EE2C680 provides the highest ripple current capacity at 1.35 A @ 100 kHz. However, this part features a reduced physical footprint (0.492" diameter, 5.00mm lead spacing) and requires PCB layout compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and manufactured by Panasonic Electronic Components with active production status.

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

A: The series designation indicates different performance grades within the Panasonic aluminum electrolytic capacitor product line. EB series parts are rated for 5000 hours at 105°C. ED and EE series parts are rated for 10000 hours at 105°C, offering extended operational lifetime. Series also correlates with physical dimensions and ripple current specifications.
