LKSH2822MESC Equivalent & Substitute Parts

Part Overview

The LKSH2822MESC is an 8200 µF, 71 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part was designed for audio applications with a rated lifetime of 1000 hours at 85°C and operates across a temperature range of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LKSH2822MESC is determined by the following critical parameters:

• Capacitance value: 8200 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Minimum 71 V (equal or higher acceptable)
• Package type: Radial, Can - Snap-In (exact match required)
• Physical dimensions: 1.378" Dia × 1.654" Height (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Polarization: Polar (exact match required)
• Operating temperature range: -40°C to 85°C (minimum requirement)

The substitute part 380LQ822M080A042 meets all substitution criteria with an upgraded voltage rating of 80 V, which provides additional design margin over the original 71 V specification.

Engineering Selection Recommendations

The 380LQ822M080A042 from Cornell Dubilier Electronics is the qualified substitute for the obsolete LKSH2822MESC. Selection is based on the following engineering factors:

• Product status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity.
• Electrical compatibility: Identical capacitance (8200 µF) and tolerance (±20%) with upgraded voltage rating (80 V vs. 71 V), providing enhanced design margin.
• Physical compatibility: Identical package dimensions, lead spacing, and mounting configuration enable direct board-level replacement without PCB redesign.
• Compliance: The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
• Thermal performance: Extended lifetime rating of 2000 hours at 85°C compared to 1000 hours for the original part.

Frequently Asked Questions (FAQ)

Q: Can the 380LQ822M080A042 be used as a direct replacement for the LKSH2822MESC?

A: Yes. Both parts share identical capacitance (8200 µF), tolerance (±20%), package type (Radial, Can - Snap-In), physical dimensions (1.378" Dia × 1.654" Height), and lead spacing (0.394"). The substitute part has a higher voltage rating (80 V vs. 71 V), which is acceptable for direct substitution.

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

A: The primary differences are manufacturer (Nichicon vs. CDE), product status (obsolete vs. active), voltage rating (71 V vs. 80 V), lifetime rating (1000 hrs vs. 2000 hrs @ 85°C), and specified ESR (not provided vs. 40 mOhm @ 120 Hz). All other electrical and mechanical parameters are identical.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: No. A higher voltage rating does not negatively impact circuit performance. The capacitor will function identically in circuits designed for 71 V operation, with the added benefit of increased voltage margin.

Q: Are there any PCB layout modifications required when switching to the substitute part?

A: No. Identical physical dimensions and lead spacing eliminate the need for PCB modifications. The substitute part is a direct mechanical and electrical replacement.

Q: What compliance certifications apply to the substitute part?

A: The 380LQ822M080A042 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
