LLS2E561MELZ Equivalent & Substitute Parts

Part Overview

The LLS2E561MELZ is a 560 µF, 250 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 85°C and operates across -40°C to 85°C. The part is Active status and ROHS3 compliant, suitable for general purpose applications requiring stable capacitance and ripple current handling in through-hole configurations.

Equivalent and substitute parts are identified when design requirements permit variations in physical dimensions, ripple current ratings, or manufacturer while maintaining core electrical specifications: 560 µF capacitance, ±20% tolerance, 250 V rated voltage, polar configuration, and through-hole radial snap-in package type.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following core parameters across all candidates:

Capacitance: 560 µF
Tolerance: ±20%
Voltage Rating: 250 V
Polarization: Polar
Lead Spacing: 0.394" (10.00 mm)

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the primary part LLS2E561MELZ.

For applications where physical space constraints are not critical, LLS2E561MELA and LLS2E561MELB offer identical electrical specifications and lifetime ratings while providing alternative form factors. Both are Nichicon manufactured parts within the same LLS series.

SLPX561M250C5P3 provides equivalent 3000-hour lifetime at 85°C with comparable ripple current performance and is suitable where cross-manufacturer substitution is acceptable. The 380LQ561M250J022 variant operates at reduced lifetime (2000 hours at 85°C) and lower ripple current ratings, making it appropriate only for applications with less demanding thermal or current cycling requirements.

Selection should prioritize available inventory, PCB layout constraints, and application-specific ripple current demands.

Frequently Asked Questions (FAQ)

Q: Can LLS2E561MELA be used as a direct replacement for LLS2E561MELZ?

A: Yes, provided PCB layout accommodates the larger diameter (25.00 mm vs. 22.00 mm) and reduced height (35.00 mm vs. 40.00 mm). Electrical specifications, voltage rating, capacitance, tolerance, and lifetime are identical.

Q: What is the primary difference between Nichicon LLS series parts and Cornell Dubilier SLPX/380LQ series?

A: Core electrical parameters (capacitance, voltage, tolerance, operating temperature) are matched. Differences exist in ripple current ratings, ESR specifications, and lifetime at 85°C. SLPX561M250C5P3 matches the 3000-hour lifetime; 380LQ561M250J022 is rated for 2000 hours.

Q: Is the 380LQ561M250J022 suitable for high-ripple-current applications?

A: No. The 380LQ561M250J022 is rated for 2.2 A ripple current at 120 Hz and 3.08 A at 20 kHz, lower than the primary part. Applications requiring sustained ripple current above these levels should use LLS2E561MELZ, LLS2E561MELA, LLS2E561MELB, or SLPX561M250C5P3.

Q: Do all substitute parts share the same lead spacing?

A: Yes. All parts listed maintain 0.394" (10.00 mm) lead spacing, ensuring PCB footprint compatibility at the connection points.

Q: Are there MSL (Moisture Sensitivity Level) considerations for substitution?

A: The primary part and most substitutes are not applicable for MSL. The 380LQ561M250J022 is rated MSL 1 (Unlimited), which does not restrict substitution but indicates different moisture handling during storage and assembly.
