Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSN2332MESC is determined by the following critical parameters:

• Capacitance Value: 3300 µF (exact match required)
• Voltage Rating: Minimum 56 V (equal or higher voltage rating acceptable)
• Package Type: Radial, Can - Snap-In (mechanical compatibility)
• Lead Spacing: 0.394" (10.00mm) (PCB footprint compatibility)
• Mounting Configuration: Through Hole (assembly method compatibility)
• Polarization: Polar (electrical polarity requirement)
• Operating Temperature Range: -40°C ~ 85°C (thermal compatibility)

The MAL205648332E3 from Vishay Beyschlag/Draloric/BC Components meets all substitution criteria with identical capacitance, tolerance, lead spacing, mounting type, and operating temperature range. The higher voltage rating (63 V vs. 56 V) provides additional design margin and is acceptable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The MAL205648332E3 is the qualified substitute for the LKSN2332MESC based on the following factors:

• Electrical Compatibility: Identical capacitance (3300 µF), tolerance (±20%), and operating temperature range (-40°C ~ 85°C). The higher voltage rating (63 V) is acceptable and provides additional safety margin in the circuit.
• Mechanical Compatibility: Identical package type (Radial, Can - Snap-In), lead spacing (10.00mm), and through-hole mounting configuration ensure direct PCB compatibility without layout modifications.
• Product Availability: The substitute part is active and in stock, addressing the obsolescence of the original LKSN2332MESC.
• Compliance Status: The MAL205648332E3 is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Performance Enhancement: The substitute offers superior lifetime rating (12000 Hrs @ 85°C vs. 1000 Hrs @ 85°C) and specified ESR characteristics, providing improved reliability for audio applications.

Frequently Asked Questions (FAQ)

Q: Can the MAL205648332E3 be used as a direct replacement for the LKSN2332MESC without PCB modifications?

A: Yes. Both parts share identical lead spacing (10.00mm), package type (Radial, Can - Snap-In), and through-hole mounting configuration. No PCB layout changes are required.

Q: Is the higher voltage rating (63 V) of the substitute part acceptable?

A: Yes. A higher voltage rating is acceptable and provides additional design margin. The circuit will operate within the specified voltage range of the substitute part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), lifetime rating (1000 Hrs vs. 12000 Hrs @ 85°C), and ESR specification (not provided vs. 55 mOhm @ 100Hz). The substitute offers superior reliability characteristics.

Q: Are there any compliance or certification differences?

A: The substitute part (MAL205648332E3) is ROHS3 compliant with specified REACH unaffected status. The original part specifications do not include ROHS compliance data. Both parts share identical ECCN (EAR99) and HTSUS (8532.22.0040) classifications.

Q: What is the physical size difference between these capacitors?

A: The LKSN2332MESC has a diameter of 1.378" (35.00mm) and height of 0.866" (22.00mm). The MAL205648332E3 has a diameter of 0.984" (25.00mm) and height of 1.654" (42.00mm). While the footprint (lead spacing) is identical, the overall form factor differs. Verify mechanical clearance in the application before substitution.

Q: Can the substitute part handle the same ripple current requirements?

A: The substitute part supports 3.14 A @ 100 Hz ripple current, compared to 2.35 A @ 120 Hz for the original part. The substitute provides adequate ripple current capacity for audio applications.
