LKSN2182MESZ Equivalent & Substitute Parts

Part Overview

The LKSN2182MESZ is a 1800 µF, 56 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part was designed for audio applications with a rated lifetime of 1000 hours at 85°C and operates across the temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LKSN2182MESZ is based on the following criteria:

• Capacitance: Must be 1800 µF (exact match)
• Voltage Rating: Substitute parts must be rated at 63 V or higher (exceeds original 56 V specification)
• Package Compatibility: Radial, can snap-in configuration with identical lead spacing (10.00 mm) and physical dimensions (22.00 mm diameter, 27.00 mm height maximum)
• Mounting Type: Through-hole configuration required
• Polarization: Polar electrolytic capacitor
• Tolerance: ±20% (maintained across substitutes)

The identified substitutes meet all mechanical and electrical compatibility requirements while offering improved or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the LKSN2182MESZ. The LLS1J182MELZ offers the longest operational lifetime at 3000 hours at 85°C and maintains Nichicon manufacturing continuity. The B41231A8188M000 provides an alternative from EPCOS - TDK Electronics with a 2000-hour lifetime rating and higher ripple current capability at 120 Hz (2.2 A versus 1.7 A in the original).

Both substitutes are ROHS3 compliant and share identical mechanical compatibility with the original part. The 63 V voltage rating of both substitutes provides operational margin above the original 56 V specification. Selection between the two substitutes should be based on supply chain availability, manufacturer preference, and specific application ripple current requirements.

Frequently Asked Questions (FAQ)

Q: Can the LLS1J182MELZ or B41231A8188M000 be used as direct replacements for the LKSN2182MESZ?

A: Yes. Both substitutes maintain identical capacitance (1800 µF), tolerance (±20%), package configuration (radial snap-in), lead spacing (10.00 mm), and physical dimensions (22.00 mm diameter, 27.00 mm height). The higher voltage ratings (63 V) are compatible with circuits designed for 56 V operation.

Q: What is the significance of the higher voltage rating in the substitute parts?

A: The 63 V rating in both substitutes exceeds the original 56 V specification, providing operational margin. This does not affect compatibility; the capacitor will function correctly in circuits rated for 56 V or lower.

Q: How do the lifetime ratings differ between the original and substitute parts?

A: The LKSN2182MESZ is rated for 1000 hours at 85°C. The LLS1J182MELZ extends this to 3000 hours, while the B41231A8188M000 provides 2000 hours. Extended lifetime ratings indicate improved thermal stability and longer operational service life.

Q: Are there compliance differences between the substitute options?

A: Both substitutes are ROHS3 compliant. The original LKSN2182MESZ compliance status is not specified in the available data. Both substitutes carry REACH Unaffected status and EAR99 ECCN classification, matching the original part's regulatory profile.

Q: What is the ripple current difference, and does it matter for my application?

A: Ripple current ratings indicate the maximum AC current the capacitor can handle at specified frequencies. The original part is rated for 1.7 A at 120 Hz. The LLS1J182MELZ provides 1.9 A, and the B41231A8188M000 provides 2.2 A at the same frequency. Higher ripple current capability provides additional design margin for power supply and audio applications.
