Parameter Comparison

Engineering Selection Recommendations

LAR2D182MELB50 Selection Criteria:

The LAR2D182MELB50 qualifies as a direct substitute with voltage upgrade capability. This Nichicon component maintains identical capacitance (1800 µF), tolerance (±20%), and mechanical dimensions while providing a higher rated voltage of 200 V. The extended lifetime rating of 2000 Hrs @ 105°C and expanded operating temperature range to 105°C offer improved thermal performance. This part is ROHS3 Compliant and REACH Unaffected, meeting all regulatory requirements. Selection of this substitute is appropriate when circuit design permits the higher voltage rating and when extended thermal performance is beneficial.

LLS2D182MELB Selection Criteria:

The LLS2D182MELB qualifies as a direct substitute with enhanced ripple current performance. This Nichicon component maintains identical capacitance (1800 µF), tolerance (±20%), and mechanical dimensions while providing a higher rated voltage of 200 V. The ripple current capability at 50 kHz reaches 6.9 A, representing a 57% increase over the main part specification. The lifetime rating of 3000 Hrs @ 85°C provides extended operational life at the primary operating temperature. This part is ROHS3 Compliant and REACH Unaffected. Selection of this substitute is appropriate for applications requiring higher ripple current handling or extended service life at 85°C operation.

Both substitute parts maintain full mechanical and electrical compatibility with the LPX182M160E9P3 within the allowed parameter tolerances for this aluminum electrolytic capacitor category.

Frequently Asked Questions (FAQ)

Q: Can LAR2D182MELB50 and LLS2D182MELB be used interchangeably with LPX182M160E9P3?

A: Both substitute parts maintain identical capacitance (1800 µF), tolerance (±20%), lead spacing (10.00 mm), diameter (30.00 mm), height (50.00 mm), and package configuration (Radial, Can - Snap-In). Mechanical and electrical substitution is valid. The rated voltage increases to 200 V on both substitutes, which is compatible with circuits designed for 160 V operation.

Q: What is the difference between LAR2D182MELB50 and LLS2D182MELB?

A: Both parts share identical capacitance, tolerance, voltage rating, and mechanical dimensions. The primary differences are: LAR2D182MELB50 offers 2000 Hrs @ 105°C lifetime with extended temperature range to 105°C; LLS2D182MELB offers 3000 Hrs @ 85°C lifetime with ripple current performance of 4.6 A @ 120 Hz and 6.9 A @ 50 kHz. Selection depends on whether thermal performance or ripple current capability is the priority.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both LAR2D182MELB50 and LLS2D182MELB are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the LPX182M160E9P3.

Q: What is the impact of the higher voltage rating on the substitute parts?

A: The substitute parts are rated at 200 V compared to the main part's 160 V rating. In circuits designed for 160 V operation, the higher voltage rating provides additional safety margin and does not negatively impact performance. The capacitance value, tolerance, and physical dimensions remain unchanged.

Q: Can these parts be used in snap-in mounting applications?

A: Yes. All three parts—LPX182M160E9P3, LAR2D182MELB50, and LLS2D182MELB—feature Radial, Can - Snap-In package configuration with identical lead spacing (10.00 mm) and mechanical dimensions, enabling direct substitution in snap-in mounting designs.

Q: What is the operating temperature range for each part?

A: LPX182M160E9P3 operates from -40°C to 85°C. LAR2D182MELB50 operates from -40°C to 105°C, providing extended high-temperature capability. LLS2D182MELB operates from -40°C to 85°C, matching the main part's temperature range.
