LKS1J682MESA Equivalent & Substitute Parts

Part Overview

The LKS1J682MESA is a 6800 µF, 63 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is rated for 1000 hours at 85°C and is designed for audio applications. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations where this capacitance and voltage rating are required.

Substitute Part Grouping Explanation

Substitution for the LKS1J682MESA is determined by strict electrical and mechanical compatibility:

Electrical Parameters (Non-Negotiable):

Capacitance: 6800 µF (exact match required)
Voltage Rating: 63 V (minimum; higher ratings acceptable)
Tolerance: ±20% (as specified)
Polarization: Polar (required for this application)

Mechanical Parameters (Required for Physical Fit):

Package Type: Radial, Can - Snap-In (snap-in mounting interface required)
Mounting Type: Through Hole
Lead Spacing: 0.394" (10.00mm) (exact match for PCB hole alignment)

Compliance Requirements:

RoHS3 Compliant
REACH Unaffected

Substitute parts must match all electrical parameters and maintain mechanical compatibility with the original PCB footprint. Physical dimensions (diameter and height) may vary within the snap-in package envelope, provided the lead spacing and mounting interface remain unchanged.

Engineering Selection Recommendations

LKS1J682MESC (Similar Substitute): This Nichicon part maintains identical electrical specifications and lead spacing as the LKS1J682MESA. Both components are obsolete products with equivalent performance characteristics. Physical dimensions differ (diameter 1.378" vs. 0.984", height 1.181" vs. 1.969"), requiring verification of available PCB space within the snap-in mounting envelope. This substitute is suitable for direct replacement where mechanical clearance permits.

SLPX682M063C9P3 (Upgrade Substitute): This Cornell Dubilier Electronics part meets all electrical and mechanical compatibility requirements with identical lead spacing and package type. The SLPX682M063C9P3 is an active product with extended lifetime (3000 hours at 85°C versus 1000 hours), higher ripple current capability (4.52 A at 120 Hz versus 3.65 A), and lower ESR (59 mOhm at 120 Hz). Physical dimensions match the LKS1J682MESA exactly (0.984" diameter, 1.969" height), ensuring direct mechanical compatibility. This part is recommended for new designs and long-term supply continuity.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can LKS1J682MESC be used as a direct replacement for LKS1J682MESA?

A: Electrical compatibility is confirmed. Both parts share identical capacitance (6800 µF), voltage rating (63 V), tolerance (±20%), lead spacing (10.00mm), and operating temperature range. Physical dimensions differ; verify that the LKS1J682MESC (1.378" diameter, 1.181" height) fits within available PCB space and the snap-in mounting envelope.

Q: What are the advantages of SLPX682M063C9P3 over the original LKS1J682MESA?

A: The SLPX682M063C9P3 offers extended operational lifetime (3000 hours at 85°C versus 1000 hours), higher ripple current capacity (4.52 A at 120 Hz versus 3.65 A), and lower equivalent series resistance (59 mOhm at 120 Hz). Physical dimensions are identical to the original part, ensuring direct mechanical fit. The part is currently in active production, providing long-term supply availability.

Q: Are all three parts mechanically interchangeable?

A: Lead spacing (10.00mm) is identical across all three parts, confirming PCB hole alignment compatibility. Physical dimensions vary: LKS1J682MESA and SLPX682M063C9P3 share identical diameter (0.984") and height (1.969"), while LKS1J682MESC differs (1.378" diameter, 1.181" height). Verify available clearance within the snap-in mounting envelope before selection.

Q: Do all substitute parts meet current compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the difference between "Similar" and "Upgrade" classifications?

A: LKS1J682MESC is classified as a similar substitute due to identical electrical specifications and obsolete status matching the original part. SLPX682M063C9P3 is classified as an upgrade substitute because it is an active product with enhanced performance characteristics (extended lifetime, higher ripple current, lower ESR) while maintaining full electrical and mechanical compatibility.
