Substitute Part Grouping Explanation

Substitution for the LKSA2153MESB is determined by strict equivalence in the following parameters:

Capacitance: 15000 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 Dimensions: 1.181" Dia (30.00 mm) × 2.047" Height (52.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Polarization: Polar (exact match required)

The substitute parts identified meet all these core mechanical and electrical compatibility criteria. Voltage rating may be equal to or higher than the original specification. Operating temperature range and lifetime ratings may exceed the original part specifications.

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the LKSA2153MESB. The 380LX153M050K052 (Cornell Dubilier Electronics) and 50MXG15000MEFCSN30X50 (Rubycon) meet all mechanical and electrical compatibility requirements for direct substitution.

The 380LX153M050K052 provides a 50 V voltage rating with 3000-hour lifetime at 85°C and carries RoHS3 compliance certification. The 50MXG15000MEFCSN30X50 offers extended operating temperature capability to 105°C with 3000-hour lifetime at that temperature and also carries RoHS3 compliance certification. Both parts are rated for -40°C to 85°C minimum operating range, meeting or exceeding the original specification.

Selection between these two substitutes depends on application-specific requirements regarding maximum operating temperature and thermal performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 380LX153M050K052 or 50MXG15000MEFCSN30X50 be used as direct replacements for the LKSA2153MESB?

A: Yes. Both substitute parts match the LKSA2153MESB in capacitance (15000 µF), tolerance (±20%), package type (radial, can snap-in), lead spacing (10.00 mm), physical dimensions (1.181" diameter × 2.047" height), and mounting configuration (through hole). The higher voltage ratings (50 V versus 42 V) are compatible with circuits designed for the original part.

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

A: The 380LX153M050K052 is rated for 3000 hours at 85°C with a maximum operating temperature of 85°C. The 50MXG15000MEFCSN30X50 is rated for 3000 hours at 105°C with a maximum operating temperature of 105°C, providing enhanced thermal performance for high-temperature applications.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the 380LX153M050K052 and 50MXG15000MEFCSN30X50 carry RoHS3 compliance certification.

Q: Will the higher voltage rating of the substitute parts affect circuit operation?

A: No. Aluminum electrolytic capacitors with higher voltage ratings are electrically compatible with circuits designed for lower voltage ratings. The 50 V substitutes will function correctly in applications specified for 42 V operation.

Q: Are the physical dimensions identical between the original and substitute parts?

A: Yes. All three parts share identical lead spacing (10.00 mm), diameter (1.181" / 30.00 mm), and seated height (2.047" / 52.00 mm), ensuring mechanical compatibility with existing PCB layouts and mounting hardware.
