LKSH2332MESZ Equivalent & Substitute Parts

Part Overview

The LKSH2332MESZ is a 3300 µF, 71 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. 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.

Substitute Part Grouping Explanation

Substitution for the LKSH2332MESZ is based on the following criteria:

• Capacitance Match: 3300 µF (exact match required)
• Voltage Rating: Minimum 71 V; higher ratings acceptable for backward compatibility
• Package Compatibility: Radial, can snap-in with identical lead spacing (10.00 mm) and physical dimensions (22.00 mm diameter, 47.00 mm height)
• Mounting Type: Through hole configuration
• Polarization: Polar (aluminum electrolytic)
• Temperature Range: -40°C to 85°C minimum

The identified substitute parts meet all mechanical and electrical compatibility requirements while offering improved product status and extended operational lifetime ratings.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with improved specifications compared to the obsolete LKSH2332MESZ. The LLS1K332MELZ offers the longest operational lifetime at 3000 hours at 85°C and maintains Nichicon manufacturing continuity. The B41231A338M provides an alternative from EPCOS - TDK Electronics with 2000 hours lifetime rating and higher ripple current capability at low frequency (4.18 A @ 120 Hz).

Both substitutes feature higher voltage ratings (80 V versus 71 V), providing enhanced margin for circuit protection. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Physical and electrical compatibility is confirmed across all critical parameters including capacitance, tolerance, package dimensions, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can LLS1K332MELZ or B41231A338M be used as direct replacements for LKSH2332MESZ?

A: Yes. Both parts are mechanically and electrically compatible. They share identical capacitance (3300 µF), package type (radial snap-in), lead spacing (10.00 mm), and physical dimensions (22.00 mm diameter, 47.00 mm height). The higher voltage ratings (80 V) are backward compatible with the original 71 V specification.

Q: What are the key differences between the two substitute options?

A: LLS1K332MELZ offers extended lifetime (3000 hours at 85°C) and maintains Nichicon manufacturing. B41231A338M provides higher ripple current capability at low frequency (4.18 A @ 120 Hz versus 3.23 A @ 120 Hz) and represents EPCOS - TDK Electronics technology.

Q: Are there any compliance or certification differences?

A: Both substitute parts are ROHS3 compliant and REACH unaffected. The original LKSH2332MESZ compliance status was not specified in available documentation.

Q: Does the higher voltage rating affect circuit performance?

A: No. The 80 V rating of substitute parts is compatible with circuits designed for 71 V operation. This provides additional safety margin without affecting functional performance.

Q: Are the ripple current specifications important for my application?

A: Ripple current ratings should be evaluated based on your specific circuit requirements. Both substitutes meet or exceed the original specification. B41231A338M provides higher ripple current capacity at low frequency (4.18 A @ 120 Hz).
