LKSA2682MESZ Equivalent & Substitute Parts

Part Overview

The Nichicon LKSA2682MESZ is a 6800 µF, 42 V aluminum electrolytic capacitor in radial, can snap-in package designed for audio applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs. The substitute parts listed maintain the same capacitance and tolerance while offering improved voltage ratings, extended lifetime specifications, and active product status from Cornell Dubilier Electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSA2682MESZ is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 6800 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Physical Dimensions: 0.866" Dia × 1.850" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Allowable Substitution Parameters:

• Voltage - Rated: 42 V (original) to 50 V (substitutes) — higher voltage rating is acceptable for backward compatibility
• Operating Temperature: -40°C ~ 85°C (original) to -40°C ~ 105°C (substitutes) — extended upper temperature range is acceptable
• Lifetime @ Temp.: 1000 Hrs @ 85°C (original) to 2000–3000 Hrs @ 85°C or 105°C (substitutes) — extended lifetime is acceptable
• ESR (Equivalent Series Resistance): Provided where available in substitute parts
• Ripple Current: Higher values in substitutes are acceptable

All four substitute parts from Cornell Dubilier Electronics meet these criteria and are direct functional replacements.

Parameter Comparison

Engineering Selection Recommendations

All four Cornell Dubilier Electronics substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment. Selection among the substitutes depends on application thermal requirements:

For standard 85°C operating environments: The 380LQ682M050H452 and 380LX682M050H452 series are suitable. The 380LX682M050H452 offers extended 3000-hour lifetime at 85°C compared to 2000 hours for the 380LQ682M050H452.

For elevated temperature environments up to 105°C: The 381LQ682M050H452 and 381LX682M050H452 series are required. The 381LX682M050H452 provides 3000-hour lifetime at 105°C, while the 381LQ682M050H452 provides 2000-hour lifetime at 105°C with lower ESR (61 mOhm vs. 73 mOhm).

All substitutes feature 50 V rated voltage, which exceeds the original 42 V specification and provides additional design margin. Physical footprint and mounting compatibility are identical across all parts.

Frequently Asked Questions (FAQ)

Q: Can the Cornell Dubilier 380LQ682M050H452 directly replace the Nichicon LKSA2682MESZ?

A: Yes. The 380LQ682M050H452 maintains identical capacitance (6800 µF), tolerance (±20%), package type (radial snap-in), physical dimensions, and lead spacing. The 50 V rating exceeds the original 42 V specification, providing backward compatibility. Operating temperature range (-40°C ~ 85°C) and through-hole mounting are identical.

Q: What is the difference between the 380LX and 381LX series substitutes?

A: The 380LX series operates to 85°C maximum, while the 381LX series operates to 105°C maximum. Both provide 3000-hour lifetime at their respective temperature ratings. Selection depends on the thermal environment of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four Cornell Dubilier substitute parts are ROHS3 compliant, meeting current regulatory requirements for electronic components.

Q: Does the higher voltage rating (50 V vs. 42 V) affect circuit operation?

A: No. A higher voltage-rated capacitor is a direct substitute in circuits designed for the original voltage. The 50 V rating provides additional safety margin and does not alter electrical performance in 42 V applications.

Q: What is the inventory status of these substitute parts?

A: All four substitute parts are in active production with current stock availability: 380LQ682M050H452 (874 pcs), 380LX682M050H452 (701 pcs), 381LQ682M050H452 (854 pcs), and 381LX682M050H452 (725 pcs).

Q: Can I use the 381LQ682M050H452 in a circuit rated for 85°C operation?

A: Yes. The 381LQ682M050H452 is rated to 105°C, so it operates safely in 85°C environments. The extended temperature rating provides additional design margin without affecting performance at lower temperatures.
