Nichicon LLS1C223MELA Equivalent & Substitute Parts

Part Overview

The Nichicon LLS1C223MELA is a 22000 µF, 16 V aluminum electrolytic capacitor in radial, can snap-in package configuration. This component is classified as Active product status and is designed for general purpose applications requiring high capacitance values in compact form factors. Equivalent and substitute parts are identified when circuit designs require alternative sourcing, inventory optimization, or when specific mechanical or electrical parameters necessitate component variation within the same functional class.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1C223MELA is determined by strict equivalence across the following parameters: capacitance value (22000 µF), voltage rating (16 V), tolerance (±20%), lifetime specification (3000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), polarization (Polar), package type (Radial, Can - Snap-In), mounting type (Through Hole), and lead spacing (0.394" / 10.00 mm). All identified substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (diameter and height) and ripple current characteristics are permitted within the substitution group, as these parameters do not affect functional compatibility in general purpose applications where the main part is specified.

Engineering Selection Recommendations

All four parts in this substitution group maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between LLS1C223MELA, LLS1C223MELB, LLS1C223MELZ, and SLPX223M016E3P3 is determined by physical space constraints and ripple current requirements within the application circuit. The Nichicon LLS series variants (MELA, MELB, MELZ) provide manufacturer continuity within the same product line. The Cornell Dubilier SLPX223M016E3P3 offers equivalent electrical performance with documented ESR specification (30 mOhm @ 120 Hz) and represents an alternative manufacturer source. Dimensional compatibility with PCB layout and mechanical mounting structure is the primary selection criterion among these electrically equivalent options.

Frequently Asked Questions (FAQ)

Q: Can LLS1C223MELB be used as a direct replacement for LLS1C223MELA?

A: Yes. Both parts share identical electrical specifications: 22000 µF capacitance, 16 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and -40°C ~ 85°C operating range. The primary difference is physical dimension: MELB measures 1.181" diameter × 1.260" height, while MELA measures 0.984" diameter × 1.654" height. Substitution is valid if PCB layout accommodates the dimensional variation.

Q: What is the difference between Nichicon LLS variants and the Cornell Dubilier SLPX223M016E3P3?

A: All four parts are electrically equivalent with identical capacitance, voltage, tolerance, and lifetime ratings. The SLPX223M016E3P3 is manufactured by Cornell Dubilier Electronics and provides an alternative sourcing option. Physical dimensions vary: SLPX223M016E3P3 measures 1.181" diameter × 1.181" height. ESR is specified for the SLPX part (30 mOhm @ 120 Hz) while ESR data is not provided for the Nichicon variants in this reference.

Q: Are all substitute parts snap-in mounted?

A: Yes. All parts in this group are specified as Radial, Can - Snap-In package type with Through Hole mounting and 0.394" (10.00 mm) lead spacing. Mechanical compatibility is maintained across the substitution group.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. All four parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component use.

Q: Which substitute part should be selected for space-constrained applications?

A: The LLS1C223MELZ offers the smallest diameter (0.866" / 22.00 mm) among the group, though it has the greatest height (2.047" / 52.00 mm). The SLPX223M016E3P3 provides the most compact overall profile (1.181" diameter × 1.181" height). Selection depends on specific PCB layout constraints and available mounting space in both radial and axial directions.
