LKSH2222MESZ Equivalent & Substitute Parts

Part Overview

The LKSH2222MESZ is a 2200 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.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LKSH2222MESZ are qualified based on the following criteria:

Electrical Parameters (Must Match or Exceed):

• Capacitance: 2200 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: Minimum 71 V (80 V rated substitutes are acceptable as they provide higher voltage margin)
• Operating Temperature Range: -40°C to 85°C (minimum requirement)
• Polarization: Polar (exact match required)

Mechanical Parameters (Must Match):

• 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: 1.457" (37.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)

Both substitute parts meet these criteria and are pin-compatible replacements for the obsolete LKSH2222MESZ.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete LKSH2222MESZ.

LLS1K222MELZ (Nichicon): This substitute maintains the same manufacturer as the original part, providing design continuity. It offers a 3000-hour lifetime at 85°C, representing a threefold improvement over the original 1000-hour rating. The 80 V voltage rating provides additional safety margin above the original 71 V specification. This part is ROHS3 compliant.

B41231A228M (EPCOS - TDK Electronics): This substitute provides the highest ripple current capability at 3.25 A @ 120 Hz, compared to 2.25 A for the original part. The 2000-hour lifetime at 85°C offers improved reliability over the original specification. This part is also ROHS3 compliant.

Both substitutes are mechanically and electrically compatible with the original LKSH2222MESZ and support direct board-level replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the LLS1K222MELZ or B41231A228M be used as direct replacements for the LKSH2222MESZ?

A: Yes. Both substitute parts are pin-compatible and mechanically identical. They share the same capacitance (2200 µF), tolerance (±20%), package type (radial snap-in), lead spacing (10.00 mm), and physical dimensions (22.00 mm diameter, 37.00 mm height). The higher voltage ratings (80 V vs. 71 V) provide additional design margin.

Q: What is the difference between the two substitute options?

A: Both are functionally equivalent for the LKSH2222MESZ application. The LLS1K222MELZ maintains Nichicon as the manufacturer and offers the longest lifetime (3000 hours @ 85°C). The B41231A228M, manufactured by EPCOS - TDK Electronics, provides the highest ripple current rating (3.25 A @ 120 Hz) and a 2000-hour lifetime at 85°C.

Q: Are both substitutes RoHS compliant?

A: Yes. Both the LLS1K222MELZ and B41231A228M are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Will the higher voltage rating of the substitutes affect circuit performance?

A: No. The 80 V rated substitutes are backward compatible with the original 71 V specification. Higher voltage ratings do not degrade performance in circuits designed for lower voltages; they only provide additional safety margin and reliability.

Q: Are there any package or mounting differences?

A: No. All three parts use identical through-hole radial snap-in packages with matching lead spacing and physical dimensions, enabling direct board-level substitution without layout modifications.
