LLS1K222MELZ Equivalent & Substitute Parts

Part Overview

The LLS1K222MELZ is a 2200 µF, 80 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 in product status and ROHS3 compliant. Equivalent and substitute parts are identified when electrical specifications (capacitance, voltage rating, tolerance, lifetime, and ripple current characteristics) and mechanical parameters (lead spacing, mounting type, and package style) align within acceptable engineering tolerances for direct circuit board replacement.

Substitute Part Grouping Explanation

Substitute parts for the LLS1K222MELZ are qualified based on the following critical parameters:

Electrical Match: Capacitance (2200 µF), voltage rating (80 V), and tolerance (±20%) must be identical
Thermal Performance: Lifetime rating of 3000 hours at 85°C is required
Operating Range: Temperature range of -40°C to 85°C must be maintained
Ripple Current: Low-frequency ripple current at 120 Hz must meet or exceed 2.53 A
Mechanical Compatibility: Lead spacing of 0.394" (10.00 mm), through-hole mounting, and radial can snap-in package style are mandatory for direct board replacement
Compliance: ROHS3 compliance is required

Two substitute parts meet these criteria: LLS1K222MELA (Nichicon, same series) and SLPX222M080C3P3 (Cornell Dubilier Electronics). Both maintain identical electrical specifications and thermal ratings while offering alternative physical dimensions and ESR characteristics.

Engineering Selection Recommendations

All three parts—LLS1K222MELZ, LLS1K222MELA, and SLPX222M080C3P3—are Active products with ROHS3 compliance and REACH Unaffected status. They share identical electrical specifications and thermal performance ratings.

The primary distinction between parts is physical dimension. The LLS1K222MELZ features a smaller diameter (22.00 mm) and greater height (37.00 mm), while both substitute parts have larger diameters (25.00 mm) with reduced heights (32.00 mm and 30.00 mm respectively). Selection depends on available board space and mechanical constraints. The SLPX222M080C3P3 provides the lowest profile option and includes specified ESR data (151 mOhm @ 120 Hz), which may be relevant for ripple current and thermal performance analysis in specific applications.

Frequently Asked Questions (FAQ)

Q: Can LLS1K222MELA be used as a direct replacement for LLS1K222MELZ?

A: Yes. Both parts share identical electrical specifications (2200 µF, 80 V, ±20% tolerance, 3000 Hrs @ 85°C) and lead spacing (10.00 mm). The primary difference is physical dimension: LLS1K222MELA has a larger diameter (25.00 mm) and shorter height (32.00 mm) compared to LLS1K222MELZ (22.00 mm diameter, 37.00 mm height). Verify available board space before substitution.

Q: Is SLPX222M080C3P3 compatible with circuits designed for LLS1K222MELZ?

A: Yes. SLPX222M080C3P3 meets all electrical and thermal requirements: 2200 µF capacitance, 80 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and 2.53 A ripple current at 120 Hz. Lead spacing is identical (10.00 mm). Physical dimensions differ: SLPX222M080C3P3 is 25.00 mm diameter and 30.00 mm height. Confirm mechanical fit before installation.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: capacitance (2200 µF), voltage rating (80 V), tolerance (±20%), lifetime (3000 Hrs @ 85°C), operating temperature range (-40°C to 85°C), ripple current at 120 Hz (2.53 A minimum), lead spacing (10.00 mm), and package type (radial, can snap-in, through-hole). All three parts meet these criteria.

Q: Does the difference in ESR between parts affect circuit performance?

A: ESR data is provided only for SLPX222M080C3P3 (151 mOhm @ 120 Hz). ESR values for LLS1K222MELZ and LLS1K222MELA are not specified in available documentation. If ESR is a critical design parameter, consult manufacturer datasheets or contact technical support for complete specifications.

Q: Are all three parts ROHS3 compliant?

A: Yes. LLS1K222MELZ, LLS1K222MELA, and SLPX222M080C3P3 are all ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
