LLS2A222MELZ Equivalent & Substitute Parts

Part Overview

The LLS2A222MELZ is a 2200 µF, 100 V aluminum electrolytic capacitor manufactured by Nichicon in the LLS series. This radial, can-style snap-in component 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 extended operational life.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design flexibility is required across manufacturing sources, or when alternative mechanical configurations better suit specific board layout constraints while maintaining electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2A222MELZ is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

Capacitance: 2200 µF (exact match)
Voltage Rating: 100 V (exact match)
Tolerance: ±20% (exact match)
Lifetime: 3000 Hrs @ 85°C (exact match)
Operating Temperature: -40°C ~ 85°C (exact match)
Polarization: Polar (exact match)

Mechanical Compatibility Requirements:

Package Type: Radial, Can - Snap-In (exact match)
Mounting Type: Through Hole (exact match)
Lead Spacing: 0.394" (10.00 mm) (exact match)

Compliance Requirements:

RoHS Status: ROHS3 Compliant (minimum requirement)

All substitute parts listed below meet these criteria. Variations in physical dimensions (diameter and height) are permitted provided the lead spacing remains constant at 10.00 mm, as these dimensional differences do not affect electrical performance or board-level compatibility in through-hole applications.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection among equivalent parts should be based on board layout constraints and available inventory.

Nichicon LLS Series Substitutes (LLS2A222MELA, LLS2A222MELB): These parts maintain manufacturer continuity with the primary LLS2A222MELZ component. They are electrically identical and differ only in physical dimensions. LLS2A222MELA offers a mid-range profile (25.00 mm diameter, 42.00 mm height), while LLS2A222MELB provides a more compact footprint (30.00 mm diameter, 32.00 mm height).

Cornell Dubilier Electronics (CDE) SLPX Series Substitutes (SLPX222M100A4P3, SLPX222M100C7P3, SLPX222M100E3P3): These parts provide cross-manufacturer equivalence with specified ESR values (121 mOhm @ 120 Hz). SLPX222M100A4P3 matches the original diameter (22.00 mm) with slightly reduced height (45.00 mm). SLPX222M100C7P3 offers mid-range dimensions (25.00 mm diameter, 40.00 mm height). SLPX222M100E3P3 provides the most compact profile (30.00 mm diameter, 30.00 mm height).

Cornell Dubilier Electronics (CDE) 380LX Series Substitute (380LX222M100K022): This part provides cross-manufacturer equivalence with specified ESR (121 mOhm). It matches the largest footprint dimensions (30.00 mm diameter, 32.00 mm height) and is available in the highest inventory quantity (2046 Pcs).

Frequently Asked Questions (FAQ)

Q: Can I substitute a part with different physical dimensions?

A: Yes. All listed substitute parts maintain the critical 10.00 mm lead spacing required for through-hole board compatibility. Variations in diameter and height do not affect electrical performance or pin-to-pin compatibility. However, verify that your PCB layout accommodates the specific dimensions of the substitute part.

Q: What is the difference between Nichicon and Cornell Dubilier Electronics parts?

A: Both manufacturers produce equivalent 2200 µF, 100 V aluminum electrolytic capacitors meeting identical electrical specifications. The primary differences are manufacturer origin and, in the case of CDE parts, specified ESR values. All parts listed are ROHS3 compliant and rated for 3000 hours at 85°C.

Q: Are the ripple current ratings interchangeable?

A: Ripple current ratings vary slightly across the substitute parts (ranging from 3.10 A to 3.21 A @ 120 Hz). These variations are within the tolerance band for general-purpose applications. Verify that your circuit's ripple current requirements do not exceed the minimum rating of the substitute part selected.

Q: What does the ±20% tolerance mean?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 1760 µF and 2640 µF. All substitute parts share this tolerance specification with the primary part, ensuring equivalent performance in applications where this tolerance band is acceptable.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, provided your PCB layout accommodates the specific dimensions of each part. The 10.00 mm lead spacing is constant across all parts, ensuring electrical compatibility. Physical space constraints may limit which substitute parts can be used in specific board locations.

Q: What is ROHS3 compliance?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, restricting the use of specific hazardous materials in electrical and electronic equipment. All parts listed meet this regulatory requirement.
