LKS2A152MESA Equivalent & Substitute Parts

Part Overview

The LKS2A152MESA is a 1500 µF, 100 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 production continuity. The part was designed for audio applications with a rated lifetime of 1000 hours at 85°C. Substitute parts maintain the same electrical specifications (capacitance, voltage, tolerance) and physical form factor while offering improved reliability characteristics or active product status from alternative manufacturers.

Engineering Selection Recommendations

Primary Recommendation: LLS2A152MELA (Nichicon)

The LLS2A152MELA is the direct active-product successor from the original manufacturer. It maintains identical electrical and mechanical specifications while providing triple the lifetime rating (3000 hours at 85°C versus 1000 hours). This part is RoHS3 compliant and carries active product status, ensuring long-term availability and supply chain stability.

Extended Temperature Applications: 100MXG1500MEFCSN25X30 (Rubycon) or EKMH101VSN152MQ30S (Chemi-Con)

For applications requiring operation at elevated temperatures up to 105°C, the 100MXG1500MEFCSN25X30 or EKMH101VSN152MQ30S provide extended operating range. Both maintain the required electrical specifications and offer 2000–3000 hour lifetimes at their respective temperature ratings. Both are RoHS3 compliant and active products.

Alternative Sources: 380LX152M100J022 (CDE) or B41231B9158M000 (EPCOS - TDK Electronics)

These parts provide additional sourcing options with active product status and RoHS3 compliance. The 380LX152M100J022 offers 3000-hour lifetime at 85°C. The B41231B9158M000 provides 2000-hour lifetime at 85°C. Both support design flexibility through multi-source qualification.

Diameter Consideration

Parts B41231B9158M000, EKMH101VSN152MQ30S, and ESMH101VSN152MQ30S have a diameter of 1.000" (25.40 mm) compared to the original 0.984" (25.00 mm). Verify PCB layout clearance before substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LKS2A152MESA with any of the listed parts?

A: Yes. All listed parts meet the core substitution criteria: 1500 µF capacitance, 100 V voltage rating, ±20% tolerance, radial snap-in package, 0.394" lead spacing, and through-hole mounting. Physical diameter variations exist for some parts; verify PCB layout compatibility.

Q: What is the primary reason to substitute the LKS2A152MESA?

A: The LKS2A152MESA is obsolete. Active substitute parts ensure continued design support, production availability, and supply chain reliability.

Q: Does the LLS2A152MELA provide a direct replacement?

A: Yes. The LLS2A152MELA is manufactured by Nichicon, the original manufacturer, and maintains identical electrical and mechanical specifications while offering improved lifetime characteristics (3000 hours at 85°C versus 1000 hours).

Q: Which substitute offers the longest operating temperature range?

A: The 100MXG1500MEFCSN25X30 (Rubycon) and EKMH101VSN152MQ30S (Chemi-Con) both support -40°C to 105°C operation, compared to -40°C to 85°C for the original part and most other substitutes.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Q: What is the significance of the diameter difference in some parts?

A: Parts B41231B9158M000, EKMH101VSN152MQ30S, and ESMH101VSN152MQ30S have a 1.000" (25.40 mm) diameter versus the original 0.984" (25.00 mm). This 0.016" difference may affect PCB layout clearance. Verify mounting hole spacing and adjacent component placement before substitution.

Q: Can I use multiple substitute parts interchangeably in the same design?

A: Yes, provided PCB layout accommodates any diameter variations and the application requirements align with each part's lifetime and temperature specifications. Multi-source qualification is supported by the active product status of all substitutes.
