Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKS1K222MESA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 2200 µF (exact match required)
• Voltage Rating: 80 V (minimum acceptable rating)
• Tolerance: ±20% (electrical performance specification)
• Package Type: Radial, Can - Snap-In (mechanical and electrical interface)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Lead Spacing: 0.394" (10.00 mm) (footprint compatibility)
• Operating Temperature Range: -40°C ~ 85°C (environmental specification)
• Polarization: Polar (electrical polarity requirement)

The LKG1K222MESCBK qualifies as a direct substitute based on matching all critical parameters. Both components are manufactured by Nichicon, share identical electrical specifications, and employ the same snap-in package configuration with compatible lead spacing and mounting requirements.

Parameter Comparison

Engineering Selection Recommendations

The LKG1K222MESCBK serves as the direct equivalent substitute for the LKS1K222MESA. Both components meet ROHS3 compliance requirements and are unaffected by REACH regulations. The substitute maintains identical electrical specifications, thermal ratings, and mechanical interface compatibility.

The primary difference between the two parts is the can diameter: the LKS1K222MESA measures 0.984" (25.00 mm), while the LKG1K222MESCBK measures 1.378" (35.00 mm). This dimensional variance requires verification of available PCB space and mechanical clearance in the target application. The substitute also provides higher ripple current capability (3.25 A @ 120 Hz versus 2.45 A @ 120 Hz), which represents an operational advantage in audio applications.

Both parts are classified as obsolete. Component selection should prioritize current inventory availability and lead time requirements for production schedules.

Frequently Asked Questions (FAQ)

Q: Can the LKG1K222MESCBK be used as a direct replacement for the LKS1K222MESA?

A: Yes, the LKG1K222MESCBK is electrically and mechanically compatible. Both components share identical capacitance, voltage rating, tolerance, temperature range, and snap-in package configuration with matching lead spacing. Physical space constraints must be evaluated due to the larger can diameter of the substitute.

Q: What is the primary difference between these two parts?

A: The can diameter differs: LKS1K222MESA is 0.984" (25.00 mm), while LKG1K222MESCBK is 1.378" (35.00 mm). The substitute provides higher ripple current capability. Both maintain identical electrical specifications and thermal ratings.

Q: Are both parts still in production?

A: No. Both the LKS1K222MESA and LKG1K222MESCBK are classified as obsolete. Component procurement should be based on available inventory from authorized distributors.

Q: Do these parts require any special handling or installation considerations?

A: Both components are polar aluminum electrolytic capacitors and must be installed with correct polarity. The snap-in package design requires proper seating on the PCB. Lead spacing of 0.394" (10.00 mm) must match the PCB footprint design.

Q: Are there any compliance or regulatory differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory status is identical.
