LLS1K682MELC Equivalent & Substitute Parts

Part Overview

The LLS1K682MELC is a 6800 µF, 80 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in capacitor is rated for 3000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, lead time considerations, or specific performance parameters within the allowed electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1K682MELC is determined by strict equivalence across the following parameters: capacitance value (6800 µF), voltage rating (80 V), tolerance (±20%), lifetime specification (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), polarization (Polar), lead spacing (10.00 mm), mounting type (Through Hole), and package configuration (Radial, Can - Snap-In). All identified substitutes meet these core electrical and mechanical requirements. Physical dimensions (diameter and height) may vary within the constraints of the snap-in package form factor. Equivalent Series Resistance (ESR) and ripple current specifications are provided where available but do not restrict substitution eligibility when core parameters align. All substitute parts maintain ROHS3 compliance and active product status.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, meeting the regulatory and supply chain requirements equivalent to the LLS1K682MELC. Selection among substitutes should be based on physical space constraints within the application. Parts with 35.00 mm diameter and 40.00-42.00 mm height (LLS1K682MELC, SLPX682M080H7P3, 80USG6800MEFCSN35X40) are suitable for compact mounting applications. Parts with 30.00 mm diameter and 50.00-52.00 mm height (LLS1K682MELB, 380LX682M080K052, SLPX682M080E9P3) accommodate applications with vertical space availability. ESR specifications provided for CDE and Rubycon parts indicate performance characteristics within the general purpose application category. Ripple current ratings across all substitutes remain within acceptable ranges for the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can LLS1K682MELB be used as a direct replacement for LLS1K682MELC?

A: Yes. Both parts share identical electrical specifications: 6800 µF capacitance, 80 V voltage rating, ±20% tolerance, 3000 hour lifetime at 85°C, and -40°C to 85°C operating range. Physical dimensions differ (diameter 30.00 mm vs. 35.00 mm; height 52.00 mm vs. 42.00 mm), requiring verification of available mounting space.

Q: What is the difference between Nichicon LLS series and Cornell Dubilier SLPX series parts?

A: Both series meet the core electrical requirements for 6800 µF, 80 V, ±20% tolerance capacitors with 3000 hour lifetime at 85°C. SLPX parts provide specified ESR values (49 mOhm @ 120 Hz), while LLS parts do not list ESR specifications. Physical dimensions vary between models within each series.

Q: Are there dimensional constraints when selecting a substitute?

A: Yes. The snap-in package form factor accommodates two primary dimensional profiles: compact (35.00 mm diameter, 40.00-42.00 mm height) and extended (30.00 mm diameter, 50.00-52.00 mm height). PCB layout and enclosure design must accommodate the selected profile. Lead spacing remains constant at 10.00 mm across all substitutes.

Q: Do all substitutes maintain the same ripple current rating?

A: Ripple current specifications vary slightly across manufacturers and series. All listed substitutes operate within the 5.16-5.83 A range at 120 Hz, suitable for general purpose applications. High-frequency ripple current (20-100 kHz) varies by part; refer to the parameter comparison table for specific values.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance, meeting regulatory requirements equivalent to the LLS1K682MELC.
