Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2E182MELC is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 1800 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Configuration: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Physical Dimensions: 1.378" Dia × 1.969" Height (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

The substitute part LGW2E182MELC50 meets all these criteria. While it features an enhanced operating temperature range (-40°C ~ 105°C versus -40°C ~ 85°C) and improved lifetime rating (3000 Hrs @ 105°C), these represent superior performance characteristics that do not compromise compatibility or functionality in applications designed for the LLS2E182MELC.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2E182MELC and LGW2E182MELC50 are active production components with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on application thermal requirements:

• LLS2E182MELC: Select for applications operating within -40°C to 85°C ambient conditions where the standard thermal rating is sufficient.
• LGW2E182MELC50: Select for applications requiring extended thermal performance, higher ambient temperatures up to 105°C, or where enhanced reliability margin is required. This part provides identical electrical and mechanical compatibility with superior thermal characteristics.

Both parts are suitable for general purpose applications and maintain identical board-level footprints and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can LGW2E182MELC50 be used as a direct replacement for LLS2E182MELC?
