Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSN2152MESA is determined by the following critical parameters:

• Capacitance Value: 1500 µF (exact match required)
• Tolerance: ±20% (must match or be tighter)
• Voltage Rating: Minimum 56 V (equal or higher acceptable)
• Package Type: Radial, Can - Snap-In (mechanical and electrical compatibility)
• Lead Spacing: 0.394" (10.00mm) (PCB footprint compatibility)
• Physical Dimensions: 0.984" Dia × 0.866" Height (board space constraints)
• Mounting Type: Through Hole (assembly process compatibility)
• Polarization: Polar (circuit polarity requirements)

The substitute part 380LX152M063J202 from Cornell Dubilier Electronics meets all critical substitution criteria. The rated voltage is increased from 56 V to 63 V, which is acceptable as higher voltage ratings provide improved reliability margins in the same physical package. All mechanical parameters, lead spacing, and mounting characteristics are identical.

Engineering Selection Recommendations

The 380LX152M063J202 from Cornell Dubilier Electronics is a direct functional substitute for the obsolete LKSN2152MESA. Selection is based on the following engineering factors:

Product Status: The LKSN2152MESA is obsolete, whereas the 380LX152M063J202 is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Compliance and Certifications: The 380LX152M063J202 is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components. Both parts carry EAR99 ECCN classification and identical HTSUS codes.

Electrical Performance: The substitute part provides identical capacitance and tolerance specifications. The increased voltage rating (63 V vs. 56 V) operates within the same physical envelope and provides enhanced reliability margins. The specified ESR of 250 mOhm and extended lifetime of 3000 hours at 85°C represent performance improvements over the original part.

Mechanical Compatibility: All physical dimensions, lead spacing, and mounting characteristics are identical, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 380LX152M063J202 be used as a direct replacement for the LKSN2152MESA without PCB modifications?

A: Yes. Both parts share identical lead spacing (10.00mm), physical dimensions (0.984" diameter, 0.866" height), and through-hole mounting type. No PCB layout changes are required.

Q: Why is the voltage rating higher on the substitute part (63 V vs. 56 V)?

A: The higher voltage rating is acceptable and beneficial. It provides improved reliability margins and operates within the same physical package. The circuit will function correctly at the lower operating voltage while benefiting from the enhanced voltage headroom.

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

A: The LKSN2152MESA is obsolete with no current compliance status. The 380LX152M063J202 is active production and RoHS3 compliant, meeting current regulatory standards for new designs and ongoing system support.

Q: What is the significance of the ESR specification on the substitute part?

A: The 380LX152M063J202 specifies an ESR of 250 mOhm, whereas the LKSN2152MESA does not provide this specification. ESR affects ripple current handling and thermal performance. The specified value on the substitute part indicates controlled electrical characteristics suitable for audio and general-purpose applications.

Q: Does the extended lifetime rating (3000 Hrs vs. 1000 Hrs @ 85°C) affect circuit operation?

A: No. Lifetime rating indicates expected operational duration under specified conditions. The longer lifetime of the substitute part represents improved component reliability and longevity, with no impact on immediate circuit functionality.

Q: Are both parts suitable for audio applications?

A: The LKSN2152MESA is specified for audio applications. The 380LX152M063J202 is rated for general-purpose applications. Both parts are aluminum electrolytic capacitors with identical electrical and mechanical specifications, making the substitute suitable for audio circuit implementations.
