LLS2D182MELB Equivalent & Substitute Parts

Part Overview

The LLS2D182MELB is a 1800 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is designed for general-purpose applications requiring high capacitance and voltage ratings with a 3000-hour lifetime at 85°C. The part is currently active in production status. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LLS2D182MELB are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance: 1800 µF (exact match required)
• Voltage Rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)

Compliance Criteria:

• RoHS3 Compliant status

All identified substitutes meet these core parameters and are therefore electrically and mechanically interchangeable with the main part in applications designed for the LLS2D182MELB.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LLS2D182MELB, LLS2D182MELC, and 380LX182M200A452—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on physical space constraints within the application enclosure.

The LLS2D182MELB features a smaller diameter (30.00mm) and greater height (50.00mm), making it suitable for applications with vertical space availability and limited horizontal footprint. The LLS2D182MELC and 380LX182M200A452 both feature larger diameters (35.00mm) with reduced heights (40.00mm and 47.00mm respectively), accommodating applications with horizontal space constraints.

Ripple current specifications are equivalent across all three parts within the stated frequency ranges, confirming electrical interchangeability for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can LLS2D182MELC be used as a direct replacement for LLS2D182MELB?

A: Yes. Both parts share identical electrical specifications: 1800 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000-hour lifetime at 85°C, and -40°C to 85°C operating temperature range. Both use radial snap-in packages with 10.00mm lead spacing and through-hole mounting. The primary difference is physical dimension: LLS2D182MELC has a larger diameter (35.00mm) and shorter height (40.00mm) compared to LLS2D182MELB (30.00mm diameter, 50.00mm height). Substitution is valid if the application PCB layout accommodates the dimensional change.

Q: Is the 380LX182M200A452 from Cornell Dubilier Electronics electrically equivalent?

A: Yes. The 380LX182M200A452 meets all core electrical parameters: 1800 µF, 200 V, ±20% tolerance, 3000-hour lifetime at 85°C, and -40°C to 85°C operating temperature. It uses the same radial snap-in package with 10.00mm lead spacing and through-hole mounting. Physical dimensions differ: 35.00mm diameter and 47.00mm height. Ripple current at high frequency is specified at 20 kHz rather than 50 kHz, but the 6 A rating remains within acceptable operating parameters for general-purpose applications.

Q: What are the key compatibility factors when selecting a substitute?

A: Electrical compatibility is guaranteed when capacitance, voltage rating, tolerance, lifetime, operating temperature range, and polarization match exactly. Mechanical compatibility requires identical package type (radial snap-in), mounting method (through-hole), and lead spacing (10.00mm). Physical dimensions (diameter and height) must be verified against PCB layout constraints and enclosure space availability. All three parts meet these criteria.

Q: Are all three parts RoHS compliant?

A: Yes. LLS2D182MELB, LLS2D182MELC, and 380LX182M200A452 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
