Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSN2272MESA is based on the following critical parameters:

Capacitance value must remain 2700 µF to maintain circuit functionality. Voltage rating must be equal to or greater than 56 V to ensure safe operation. Package dimensions (diameter, height, lead spacing) must match exactly to ensure mechanical compatibility with existing PCB layouts and snap-in mounting hardware. Polarization must remain polar. Tolerance specification of ±20% is acceptable for this application category.

The substitute part 63MXG2700MEFCSN25X25 meets all these criteria with identical capacitance, matching package geometry, and higher voltage rating (63 V), which provides improved safety margin.

Parameter Comparison

Engineering Selection Recommendations

The 63MXG2700MEFCSN25X25 from Rubycon is a direct mechanical and electrical substitute for the obsolete LKSN2272MESA. The substitute part maintains identical capacitance, tolerance, and package geometry while providing a higher voltage rating (63 V versus 56 V), which offers improved operational margin. The substitute is currently in active production status, ensuring long-term availability.

The Rubycon part demonstrates superior reliability characteristics with a rated lifetime of 3000 hours at 105°C compared to the original 1000 hours at 85°C. The substitute meets ROHS3 compliance requirements, supporting modern manufacturing and environmental standards. Ripple current specifications are equivalent between the two parts at 120 Hz operation.

Frequently Asked Questions (FAQ)

Q: Can the 63MXG2700MEFCSN25X25 be used as a direct replacement for LKSN2272MESA?

A: Yes. Both parts share identical capacitance (2700 µF), tolerance (±20%), package type (radial snap-in), and mechanical dimensions (25 mm diameter, 27 mm height, 10 mm lead spacing). The substitute operates at a higher voltage rating (63 V), which is compatible with circuits designed for 56 V operation.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Nichicon versus Rubycon), product status (obsolete versus active), voltage rating (56 V versus 63 V), and lifetime rating (1000 hours at 85°C versus 3000 hours at 105°C). The substitute offers improved reliability and compliance certifications.

Q: Will the snap-in mounting interface work identically?

A: Yes. Both parts use identical lead spacing (10 mm) and package dimensions, ensuring compatibility with existing snap-in mounting hardware and PCB layouts.

Q: Is the higher voltage rating of the substitute a concern?

A: No. A higher voltage rating does not create compatibility issues in circuits designed for lower voltages. The 63 V rating of the substitute provides additional safety margin in the 56 V application.

Q: What is the compliance status of the substitute part?

A: The 63MXG2700MEFCSN25X25 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
