LLS2D561MELY Equivalent & Substitute Parts

Part Overview

The LLS2D561MELY is a 560 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in capacitor is rated for 3000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part is Active status and ROHS3 compliant, making it suitable for general-purpose applications requiring stable capacitance and ripple current handling. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2D561MELY is determined by the following critical parameters:

• Capacitance value: 560 µF (exact match required)
• Voltage rating: 200 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 3000 Hrs @ 85°C (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Lead spacing: 0.394" (10.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package style: Radial, Can - Snap-In (exact match required)
• Polarization: Polar (exact match required)

The LLS2D561MELB meets all substitution criteria. Physical dimensions (diameter and height) may vary within the snap-in package envelope without affecting electrical performance or circuit board compatibility, provided lead spacing and mounting type remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both LLS2D561MELY and LLS2D561MELB are Active status products with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on physical space constraints within the application:

The LLS2D561MELY features a smaller diameter (20.00mm) with greater height (40.00mm), suitable for applications with vertical space availability and limited horizontal footprint.

The LLS2D561MELB features a larger diameter (30.00mm) with reduced height (25.00mm), suitable for applications with horizontal space availability and limited vertical clearance.

Both parts deliver equivalent electrical performance with negligible differences in ripple current specifications (2.15–2.18 A @ 120 Hz; 3.225–3.27 A @ 50 kHz). Lead spacing, mounting type, and snap-in package compatibility remain identical, ensuring direct circuit board compatibility when physical envelope constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can LLS2D561MELB replace LLS2D561MELY in any application?

A: Direct replacement is possible only when the physical dimensions of LLS2D561MELB (30.00mm diameter, 25.00mm height) fit within the available circuit board space. Lead spacing (10.00mm) and mounting type (through hole, snap-in) are identical, ensuring electrical and mechanical compatibility. Verify available space before substitution.

Q: What are the key differences between these two parts?

A: The primary differences are physical dimensions and ripple current specifications. LLS2D561MELY is 20.00mm diameter × 40.00mm height with 2.18 A ripple current @ 120 Hz. LLS2D561MELB is 30.00mm diameter × 25.00mm height with 2.15 A ripple current @ 120 Hz. All electrical parameters (capacitance, voltage, tolerance, lifetime, temperature range) are identical.

Q: Are both parts ROHS3 compliant?

A: Yes, both LLS2D561MELY and LLS2D561MELB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of the snap-in package style?

A: The snap-in package allows the capacitor to be mechanically secured to the circuit board without solder, reducing assembly time and thermal stress. Both substitute parts use identical snap-in mounting with 10.00mm lead spacing, ensuring compatibility with existing board layouts designed for this package type.

Q: Can these capacitors be used interchangeably in high-ripple-current applications?

A: Both parts are rated for similar ripple currents (2.15–2.18 A @ 120 Hz; 3.225–3.27 A @ 50 kHz). The minor differences are within normal manufacturing tolerance and do not affect suitability for equivalent ripple current applications. Verify that the application's actual ripple current does not exceed the rated specifications of either part.
