ECA-1AM682 Equivalent & Substitute Parts

Part Overview

The ECA-1AM682 is a 6800 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C and is designed for general-purpose applications requiring high capacitance in a compact through-hole form factor. The part is ROHS3 compliant and currently active in production.

Equivalent and substitute parts are necessary when the original component becomes unavailable, when design requirements demand extended operational lifetime, improved ripple current handling, or when higher voltage ratings are required for circuit margin enhancement.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications (capacitance, tolerance, voltage rating) and mechanical dimensions (lead spacing, case diameter, height) while potentially offering improved lifetime or operating temperature range.

Upgrade Substitutes provide enhanced performance characteristics such as extended lifetime at elevated temperature or improved ripple current handling, while maintaining identical capacitance, voltage rating, and mechanical compatibility.

Similar Substitutes share the same electrical specifications but differ in mechanical dimensions (case diameter or height), requiring PCB layout verification before implementation.

Parametric Equivalents match the primary electrical and mechanical specifications but may have minor variations in ripple current performance or impedance characteristics.

Voltage Upgrade Substitutes increase the rated voltage above the original specification, providing additional circuit margin while maintaining the same capacitance and mechanical form factor.

Engineering Selection Recommendations

Direct Mechanical and Electrical Compatibility (No PCB Modification Required)

ECA-1AHG682 (Panasonic NHG-A series) provides direct substitution with identical mechanical dimensions and improved thermal performance. Operating temperature range extends to 105°C with lifetime rated at 2000 hours at this elevated temperature. Product status is Active, suitable for new designs.

10YXJ6800M16X25 (Rubycon YXJ series) and 10ZLH6800MEFC16X25 (Rubycon ZLH series) maintain identical case dimensions and lead spacing. Both are Active products. The YXJ variant offers 8000-hour lifetime at 105°C, while the ZLH variant extends to 10000 hours at 105°C with improved ripple current handling (3.63 A @ 100 kHz).

UVR1A682MHD (Nichicon UVR series) matches mechanical specifications exactly but carries Not For New Designs status. This part is suitable only for legacy system maintenance or replacement applications.

Mechanical Incompatibility (PCB Layout Verification Required)

UKL1A682MHD and URS1A682MHD differ in case diameter (18.00 mm vs. 16.00 mm) and/or height. UKL1A682MHD increases to 37.00 mm height, while URS1A682MHD reduces to 21.50 mm height. These parts require PCB footprint verification before implementation.

Voltage Upgrade Option

UVK1C682MHD (Nichicon UVK series) increases rated voltage to 16 V while maintaining identical case dimensions. This part carries Not For New Designs status and is suitable only for replacement applications requiring voltage margin enhancement.

Obsolescence Considerations
