LLS1V223MELC Equivalent & Substitute Parts

Part Overview

The LLS1V223MELC is a 22000 µF, 35 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is designed for general-purpose applications requiring high capacitance values with a rated lifetime of 3000 hours at 85°C. The part is currently active in production and RoHS3 compliant. Substitute parts are necessary when the primary manufacturer part is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1V223MELC is determined by strict equivalence across the following critical parameters:

• Capacitance: 22000 µF (exact match required)
• Voltage Rating: 35 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (diameter and height) and ESR characteristics are permitted within the scope of snap-in package design flexibility, provided all primary parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts—SLPX223M035H4P3, 380LX223M035A042, and 380LX223M035K052—are electrically and mechanically equivalent to the LLS1V223MELC and meet the same compliance requirements. All parts are RoHS3 compliant, REACH unaffected, and maintain active production status.

Physical dimension variations exist among the substitute options. The SLPX223M035H4P3 and 380LX223M035A042 maintain the same 1.378" (35.00mm) diameter as the primary part, with height differences of 1.772" (45.00mm) and 1.654" (42.00mm) respectively. The 380LX223M035K052 features a reduced diameter of 1.181" (30.00mm) with a height of 2.047" (52.00mm). PCB layout and mechanical clearance constraints must be evaluated when selecting among these options.

ESR performance varies slightly across substitutes. The SLPX223M035H4P3 offers the lowest ESR at 24 mOhm @ 120 Hz, while both 380LX variants specify 26 mOhm. Ripple current handling at 120 Hz is 6.38 A for the Nichicon primary and SLPX substitute, compared to 6.1 A for the 380LX variants. These differences remain within acceptable operating margins for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can SLPX223M035H4P3 be used as a direct replacement for LLS1V223MELC?

A: Yes. Both parts share identical electrical specifications: 22000 µF capacitance, 35 V rating, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and -40°C ~ 85°C operating range. Both use radial snap-in packages with 0.394" (10.00mm) lead spacing. Physical height differs by 0.078" (2.00mm), which must be verified against PCB clearance requirements.

Q: What is the difference between the 380LX223M035A042 and 380LX223M035K052?

A: Both parts are electrically identical with 22000 µF capacitance and 35 V rating. The primary difference is physical dimension: 380LX223M035A042 has a 1.378" (35.00mm) diameter and 1.654" (42.00mm) height, while 380LX223M035K052 has a reduced 1.181" (30.00mm) diameter but increased 2.047" (52.00mm) height. Selection depends on available PCB space constraints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—SLPX223M035H4P3, 380LX223M035A042, and 380LX223M035K052—are RoHS3 compliant and REACH unaffected, matching the compliance status of the LLS1V223MELC.

Q: Does ESR variation affect circuit performance?

A: ESR differences between parts are minor. The primary part does not specify ESR; substitutes range from 24 mOhm to 26 mOhm @ 120 Hz. These values are functionally equivalent for general-purpose applications. Applications with strict ESR requirements should specify the SLPX223M035H4P3, which offers the lowest ESR at 24 mOhm.

Q: Can I use 380LX223M035K052 if my PCB has limited horizontal space?

A: Yes, if vertical space is available. The 380LX223M035K052 has a reduced diameter of 1.181" (30.00mm) compared to 1.378" (35.00mm) for other options, but requires 2.047" (52.00mm) of vertical clearance, which is the maximum height among all substitutes.
