LKSH2182MESZ Equivalent & Substitute Parts

Part Overview

The LKSH2182MESZ is a 1800 µF, 71 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is classified as obsolete, making substitute parts 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.

Substitute Part Grouping Explanation

Substitution for the LKSH2182MESZ is determined by strict adherence to the following electrical and mechanical parameters:

Core Substitution Criteria:

Capacitance: 1800 µF (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Physical Diameter: 0.866" (22.00 mm) (exact match required)
Height - Seated (Max): 1.260" (32.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

Voltage Rating Substitution Logic: Substitute parts must have a voltage rating equal to or greater than the original 71 V rating. All qualified substitutes meet or exceed this requirement.

All five substitute parts listed below satisfy these mandatory criteria and are therefore electrically and mechanically compatible with the LKSH2182MESZ.

Engineering Selection Recommendations

All five substitute parts are active products with current manufacturing status, providing supply chain continuity for the obsolete LKSH2182MESZ. Selection among these substitutes should be based on the following factors:

Compliance and Regulatory Status: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original LKSH2182MESZ does not specify RoHS compliance status.

Voltage Rating Considerations: The 100MXG1800MEFCSN22X30 offers the highest voltage rating at 100 V, providing maximum design margin. The LLS1K182MELZ, 80MXG1800MEFCSN22X30, B41231A0188M000, and ESMH800VSN182MP30S all provide 80 V ratings, which exceed the original 71 V specification.

Lifetime and Temperature Performance: The Rubycon MXG series parts (80MXG1800MEFCSN22X30 and 100MXG1800MEFCSN22X30) offer extended operating temperature range to 105°C and 3000-hour lifetime at 105°C, providing superior thermal performance. The Nichicon LLS1K182MELZ provides 3000-hour lifetime at 85°C. The EPCOS B41231A0188M000 and Chemi-Con ESMH800VSN182MP30S provide 2000-hour lifetime at 85°C.

Manufacturer Availability: All substitute parts are currently in stock with inventory levels ranging from 920 to 1787 pieces, ensuring immediate availability.

Frequently Asked Questions (FAQ)

Q: Can the LKSH2182MESZ be directly replaced with any of these substitute parts?

A: Yes. All five substitute parts are direct replacements. They share identical capacitance (1800 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00 mm), physical dimensions (22.00 mm diameter, 32.00 mm height), and mounting type (Through Hole). All substitute parts have voltage ratings equal to or greater than the original 71 V specification.

Q: What is the difference between the 80 V and 100 V rated substitutes?

A: The 100MXG1800MEFCSN22X30 provides a higher voltage rating (100 V versus 80 V) and extended operating temperature range to 105°C. The 80 V rated substitutes (LLS1K182MELZ, 80MXG1800MEFCSN22X30, B41231A0188M000, ESMH800VSN182MP30S) are suitable for applications where the original 71 V specification is adequate.

Q: Are there any physical compatibility concerns with these substitutes?

A: No. All substitute parts maintain identical lead spacing (10.00 mm), can diameter (22.00 mm), and seated height (32.00 mm). They are mechanically interchangeable on existing PCB layouts designed for the LKSH2182MESZ.

Q: Which substitute offers the best long-term reliability?

A: The Rubycon MXG series parts (80MXG1800MEFCSN22X30 and 100MXG1800MEFCSN22X30) provide the longest rated lifetime of 3000 hours at their respective temperature ratings (105°C). The Nichicon LLS1K182MELZ provides 3000 hours at 85°C.

Q: Are all substitutes RoHS compliant?

A: Yes. All five substitute parts are ROHS3 compliant. The original LKSH2182MESZ does not specify RoHS compliance status.

Q: What is the inventory status of these substitutes?

A: All substitute parts are currently in stock as new original components. Inventory levels range from 920 pieces (ESMH800VSN182MP30S) to 1787 pieces (B41231A0188M000).
