Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSA2222MESA is determined by the following critical parameters:

• Capacitance Value: 2200 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Polarization: Polar (exact match required)

The substitute part MAL205659222E3 meets all critical substitution criteria. While the rated voltage is higher (100 V vs. 42 V), this represents an acceptable over-specification for the electrical function. Physical dimensions differ slightly in diameter and height, which must be verified against PCB layout constraints before implementation.

Engineering Selection Recommendations

The MAL205659222E3 is the identified substitute for the obsolete LKSA2222MESA based on matching electrical and mechanical specifications. Key considerations for selection:

• Product Status: The substitute part is active and in production, ensuring long-term availability compared to the obsolete main part.
• Compliance: Both parts maintain REACH Unaffected status, indicating equivalent regulatory compliance.
• Physical Compatibility: The substitute has larger physical dimensions (30.00mm diameter vs. 25.00mm, and 42.00mm height vs. 22.00mm). PCB layout verification is required to confirm clearance and mounting compatibility.
• Electrical Performance: The substitute provides higher voltage rating (100 V vs. 42 V) and extended lifetime (12000 Hrs vs. 1000 Hrs @ 85°C), representing improved reliability margins.

Frequently Asked Questions (FAQ)

Q: Can MAL205659222E3 be used as a direct replacement for LKSA2222MESA?

A: MAL205659222E3 matches the critical electrical parameters (2200 µF, ±20% tolerance, polar, through-hole snap-in package, 10.00mm lead spacing). However, physical dimensions differ significantly. Verify PCB layout clearance before implementation.

Q: Why is the voltage rating different between the main part and substitute?

A: The substitute part has a 100 V rating versus the main part's 42 V rating. This over-specification is acceptable for circuit operation at the original 42 V design voltage and provides additional safety margin.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical REACH Unaffected status. The substitute part is RoHS3 Compliant, while the main part's RoHS status is not specified in available data.

Q: What is the impact of the larger physical dimensions?

A: The substitute part is larger in both diameter (30.00mm vs. 25.00mm) and height (42.00mm vs. 22.00mm). PCB layout must accommodate these dimensions, including clearance for snap-in mounting and adjacent components.

Q: Does the substitute part have better performance characteristics?

A: The substitute provides extended operational lifetime (12000 Hrs @ 85°C vs. 1000 Hrs) and higher ripple current capability (2.27 A @ 100 Hz vs. 1.55 A @ 120 Hz), indicating improved reliability for the same capacitance value.
