LKSA2472MESC Equivalent & Substitute Parts

Part Overview

The LKSA2472MESC is a 4700 µF, 42 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is designed for audio applications requiring high capacitance values with moderate voltage ratings. The part is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LKSA2472MESC is determined by the following critical parameters:

• Capacitance: Must be 4700 µF (exact match required)
• Tolerance: Must be ±20% (exact match required)
• Package / Case: Must be Radial, Can - Snap-In (exact match required)
• Lead Spacing: Must be 0.394" (10.00mm) (exact match required)
• Mounting Type: Must be Through Hole (exact match required)
• Polarization: Must be Polar (exact match required)

The MAL209018472E3 manufactured by Vishay Beyschlag/Draloric/BC Components meets all mandatory substitution criteria. While this substitute features a higher rated voltage (63 V versus 42 V), improved ESR characteristics, extended lifetime rating, and wider operating temperature range, these represent performance enhancements rather than deviations from the core electrical and mechanical specifications required for direct substitution.

Engineering Selection Recommendations

The MAL209018472E3 is the qualified substitute for the obsolete LKSA2472MESC. Selection is based on:

• Product Status: The LKSA2472MESC is obsolete; the MAL209018472E3 is active and currently in production, ensuring long-term availability.
• Compliance: Both parts maintain REACH Unaffected status and EAR99 ECCN classification, preserving regulatory compliance.
• Electrical Compatibility: Identical capacitance (4700 µF) and tolerance (±20%) ensure functional equivalence in audio applications. The higher rated voltage (63 V) of the substitute provides additional safety margin in the 42 V application.
• Mechanical Compatibility: Both parts feature identical lead spacing (10.00mm) and through-hole mounting, enabling direct PCB footprint compatibility.

Physical dimensions differ slightly; verify clearance in the target assembly before implementation.

Frequently Asked Questions (FAQ)

Q: Can the MAL209018472E3 be used as a direct replacement for the LKSA2472MESC?

A: Yes. Both parts share identical capacitance (4700 µF), tolerance (±20%), lead spacing (10.00mm), and package type (Radial, Can - Snap-In). The substitute is mechanically and electrically compatible for through-hole mounting applications.

Q: Why does the substitute have a higher voltage rating (63 V vs. 42 V)?

A: Higher voltage ratings do not prevent substitution in lower-voltage applications. The 63 V rating of the MAL209018472E3 provides additional voltage margin and does not affect performance in a 42 V circuit.

Q: Are there physical dimension differences between these parts?

A: Yes. The LKSA2472MESC has a diameter of 1.378" (35.00mm) and height of 0.866" (22.00mm). The MAL209018472E3 has a diameter of 1.181" (30.00mm) and height of 1.260" (32.00mm). Verify clearance in your specific PCB layout and enclosure before substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are REACH Unaffected and classified as EAR99, maintaining equivalent regulatory compliance for audio applications.

Q: What is the lead spacing for both parts?

A: Both the LKSA2472MESC and MAL209018472E3 have a lead spacing of 0.394" (10.00mm), ensuring PCB footprint compatibility.
