LKSA2562MESA Equivalent & Substitute Parts

Part Overview

The LKSA2562MESA is a 5600 µF, 42 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as obsolete, making direct replacement necessary for ongoing production and maintenance applications. The part was designed for audio applications with a rated lifetime of 1000 hours at 85°C. Equivalent and substitute parts listed below maintain the same capacitance and tolerance while offering improved voltage ratings, extended operational lifetimes, and active product status from multiple manufacturers.

Engineering Selection Recommendations

All substitute parts are electrically and mechanically compatible with the LKSA2562MESA. Selection should be based on the following factors:

Manufacturer Continuity: LLS1H562MELA (Nichicon) maintains the same manufacturer as the original part, providing design continuity and supply chain consistency.

Compliance Status: All substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. The original LKSA2562MESA does not specify RoHS compliance.

Extended Operational Life: Substitute parts offer 2000 to 3000 hour lifetimes at 85°C or 105°C, compared to the original 1000 hour rating at 85°C. This represents a 2x to 3x improvement in component longevity.

Voltage Margin: All substitutes are rated at 50 V, providing an 8 V margin above the original 42 V specification. This improves reliability in applications with voltage transients or ripple.

Temperature Range: Parts rated to 105°C (381LQ562M050J032, 381LX562M050J032, 50MXG5600MEFCSN25X35) offer extended thermal operating range compared to the original 85°C maximum.

Inventory Availability: All substitute parts are in active production with confirmed stock quantities ranging from 797 to 4703 units.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of the 42 V original? A: Yes. Higher voltage ratings are acceptable substitutes. The 50 V rated parts provide improved voltage margin and reliability without affecting circuit performance.

Q: Are all substitute parts mechanically identical to the LKSA2562MESA? A: Yes. All substitute parts share identical lead spacing (10.00mm), case diameter (25.00mm), and seated height (37.00mm). They are direct mechanical replacements in snap-in mounting applications.

Q: What is the difference between the Nichicon LLS1H562MELA and the CDE 380LX562M050J032? A: Both are electrically equivalent with 5600 µF capacitance and 50 V rating. The LLS1H562MELA maintains Nichicon manufacturer continuity and offers 3000 hour lifetime at 85°C. The 380LX562M050J032 is from Cornell Dubilier Electronics and also offers 3000 hour lifetime at 85°C with lower ESR (60mOhm @ 120Hz).

Q: Which substitute offers the longest operational life? A: The 381LX562M050J032, 381LQ562M050J032, and 50MXG5600MEFCSN25X35 all offer 3000 hour lifetimes at elevated temperatures (105°C), compared to the original 1000 hour rating at 85°C.

Q: Are these parts suitable for audio applications? A: Yes. All substitute parts are rated for general purpose applications and maintain the same capacitance and tolerance specifications as the original audio-rated LKSA2562MESA.

Q: What is the ESR difference between substitute parts? A: The 380LX562M050J032 specifies 60mOhm @ 120Hz, the 380LQ562M050J032 specifies 89mOhm @ 120Hz, and the 381LQ562M050J032 specifies 74mOhm @ 120Hz. Lower ESR values indicate better high-frequency performance and reduced heat generation.
