Nichicon LLS2V561MELB Equivalent & Substitute Parts

Part Overview

The Nichicon LLS2V561MELB is a 560 µF, 350 V aluminum electrolytic capacitor with radial, can snap-in mounting. This through-hole component is rated for 3000 hours at 85°C and operates across a temperature range of -25°C to 85°C. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2V561MELB is determined by strict alignment of the following critical parameters:

• Capacitance value: 560 µF (exact match required)
• Voltage rating: 350 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead spacing: 0.394" (10.00 mm) (exact match required)
• Package type: Radial, Can - Snap-In (exact match required)
• Mounting type: Through Hole (exact match required)

The LLS2V561MELC meets all substitution criteria. Physical dimensions (can diameter and height) may vary within the snap-in package specification without affecting electrical performance or circuit board compatibility, provided lead spacing and mounting type remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both the LLS2V561MELB and LLS2V561MELC are active production parts with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is based on physical space constraints within the application. The LLS2V561MELB features a smaller can diameter (30.00 mm) and greater height (42.00 mm), while the LLS2V561MELC has a larger can diameter (35.00 mm) and reduced height (37.00 mm). Both configurations maintain the same 10.00 mm lead spacing and snap-in mounting interface. Verify available board space and mounting clearance to determine the appropriate variant for your application.

Frequently Asked Questions (FAQ)

Q: Can the LLS2V561MELC replace the LLS2V561MELB in my circuit?

A: Yes, provided that the physical dimensions of the LLS2V561MELC (1.378" diameter, 1.457" height) fit within your available board space. All electrical parameters, lead spacing, and mounting type are identical.

Q: What is the difference between these two parts?

A: The primary differences are physical dimensions. The LLS2V561MELB has a 30.00 mm diameter can with 42.00 mm height, while the LLS2V561MELC has a 35.00 mm diameter can with 37.00 mm height. Lead spacing (10.00 mm) and all electrical specifications remain constant.

Q: Are both parts compliant with current regulations?

A: Yes. Both the LLS2V561MELB and LLS2V561MELC are ROHS3 compliant and REACH unaffected.

Q: What determines if a part can substitute for the LLS2V561MELB?

A: Substitution requires exact matching of capacitance (560 µF), voltage rating (350 V), tolerance (±20%), polarization (polar), lead spacing (10.00 mm), package type (radial, can snap-in), and mounting type (through hole). Physical can dimensions may vary within the snap-in specification.

Q: Can I use a different capacitance value or voltage rating?

A: No. The capacitance and voltage rating must remain at 560 µF and 350 V respectively to maintain circuit performance and safety margins.
