Nichicon LLS2D561MELZ Equivalent & Substitute Parts

Part Overview

The Nichicon LLS2D561MELZ is a 560 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is designed for general-purpose applications requiring stable capacitance performance across extended operating temperatures. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part number becomes unavailable or when alternative mechanical configurations better suit specific board layout requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D561MELZ is determined by strict equivalence across the following critical parameters: capacitance value (560 µF), voltage rating (200 V), tolerance (±20%), polarization (Polar), package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (0.394" / 10.00 mm). All identified substitute parts maintain identical electrical specifications and mechanical compatibility with the main part number. Variations in physical dimensions (diameter and height) do not affect electrical substitution eligibility but must be evaluated against specific board layout constraints. All substitute parts retain Active product status, RoHS3 compliance, and equivalent lifetime ratings.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LLS2D561MELZ, LLS2D561MELB, and LLS2D561MELY—are electrically equivalent and maintain full Active product status with RoHS3 compliance and REACH unaffected designation. Selection between these parts is determined solely by mechanical fit requirements within the target application. The LLS2D561MELZ (22.00 mm diameter, 35.00 mm height) and LLS2D561MELY (20.00 mm diameter, 40.00 mm height) offer comparable footprints with minimal dimensional variation. The LLS2D561MELB (30.00 mm diameter, 25.00 mm height) provides a wider, shorter profile suitable for applications with horizontal space constraints and limited vertical clearance. All parts deliver equivalent electrical performance and regulatory compliance, making selection a function of available board real estate and mechanical constraints rather than electrical performance differentiation.

Frequently Asked Questions (FAQ)

Q: Are LLS2D561MELZ, LLS2D561MELB, and LLS2D561MELY electrically interchangeable?

A: Yes. All three parts share identical electrical specifications: 560 µF capacitance, 200 V voltage rating, ±20% tolerance, 3000 hour lifetime at 85°C, and equivalent ripple current ratings. They are direct electrical equivalents suitable for circuit-level substitution.

Q: What is the primary difference between these substitute parts?

A: Physical dimensions differ. The LLS2D561MELZ measures 22.00 mm diameter × 35.00 mm height. The LLS2D561MELB measures 30.00 mm diameter × 25.00 mm height. The LLS2D561MELY measures 20.00 mm diameter × 40.00 mm height. All maintain identical 10.00 mm lead spacing and through-hole mounting configuration.

Q: Can I substitute LLS2D561MELB for LLS2D561MELZ on an existing PCB?

A: Electrical substitution is valid. However, the LLS2D561MELB's larger diameter (30.00 mm vs. 22.00 mm) and reduced height (25.00 mm vs. 35.00 mm) require verification of available board space. Lead spacing remains constant at 10.00 mm, ensuring footprint compatibility at the mounting holes.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. LLS2D561MELZ, LLS2D561MELB, and LLS2D561MELY are all RoHS3 compliant, REACH unaffected, and carry Active product status. No compliance differentiation exists between these parts.

Q: Which part should I select for space-constrained applications?

A: The LLS2D561MELY (20.00 mm diameter) offers the smallest radial footprint. The LLS2D561MELB (25.00 mm height) provides the lowest profile for applications with limited vertical clearance. Selection depends on whether horizontal or vertical space is the limiting factor.
