LLS2Z182MELB Equivalent & Substitute Parts

Part Overview

The LLS2Z182MELB is a 1800 µF, 180 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in capacitor 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 with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance can be maintained within the allowed parameter tolerances for the application, ensuring functional interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2Z182MELB is determined by the following critical parameters:

• Capacitance: Must be 1800 µF (within ±20% tolerance band)
• Voltage Rating: Must be equal to or greater than 180 V
• Package / Case: Must be Radial, Can - Snap-In
• Lead Spacing: Must be 10.00 mm
• Diameter: Must be 30.00 mm
• Mounting Type: Must be Through Hole
• Series Compatibility: LLS series preferred for electrical and thermal characteristics

The substitute part LLS2D182MELB meets all substitution criteria with an increased voltage rating of 200 V, which provides additional design margin while maintaining identical mechanical fit and electrical performance in the 180 V application.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2Z182MELB and LLS2D182MELB are active production parts with full RoHS3 and REACH compliance. The LLS2D182MELB substitute offers a 200 V voltage rating compared to the 180 V main part, providing increased voltage margin while maintaining identical capacitance, tolerance, thermal lifetime, and mechanical dimensions.

The substitute part is mechanically compatible with a maximum seated height of 50.00 mm versus 45.00 mm for the main part. Verify PCB layout clearance before substitution if height-constrained applications are present.

Both parts are manufactured by Nichicon in the LLS series and share identical lead spacing (10.00 mm), diameter (30.00 mm), and mounting type (Through Hole, Radial, Can - Snap-In). Ripple current ratings are equivalent within measurement tolerance.

Frequently Asked Questions (FAQ)

Q: Can LLS2D182MELB replace LLS2Z182MELB in a 180 V circuit?

A: Yes. The LLS2D182MELB is rated for 200 V, which exceeds the 180 V requirement. The higher voltage rating provides additional design margin and does not degrade performance in lower-voltage applications.

Q: Are the mechanical dimensions identical?

A: Lead spacing (10.00 mm) and diameter (30.00 mm) are identical. The seated height differs: LLS2Z182MELB is 45.00 mm maximum, while LLS2D182MELB is 50.00 mm maximum. Verify PCB clearance for the substitute part.

Q: Do both parts have the same capacitance and tolerance?

A: Yes. Both parts are 1800 µF with ±20% tolerance, ensuring equivalent electrical performance in the application.

Q: Are both parts RoHS3 compliant?

A: Yes. Both LLS2Z182MELB and LLS2D182MELB are ROHS3 Compliant and REACH Unaffected.

Q: What is the thermal lifetime specification?

A: Both parts are rated for 3000 hours at 85°C operating temperature, with an operating range of -40°C to 85°C.

Q: Are ripple current ratings equivalent?

A: Ripple current ratings are equivalent within measurement tolerance. LLS2Z182MELB: 4.55 A @ 120 Hz, 6.825 A @ 50 kHz. LLS2D182MELB: 4.6 A @ 120 Hz, 6.9 A @ 50 kHz.
