LLS1H222MELZ Equivalent & Substitute Parts

Part Overview

The LLS1H222MELZ is a 2200 µF, 50 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Nichicon. This component is rated for 3000 hours at 85°C and is designed for general-purpose applications requiring high capacitance in a compact through-hole form factor. The part is currently active in production with full RoHS3 compliance.

Equivalent and substitute parts are identified when design requirements allow flexibility in manufacturer selection while maintaining electrical and mechanical compatibility within the specified parameter tolerances for this capacitor category.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1H222MELZ is determined by strict equivalence across the following critical parameters:

• Capacitance: 2200 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Diameter: 0.866" (22.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

Two substitute parts meet these criteria:

1. SLPX222M050A1P3 (Cornell Dubilier Electronics) - Direct equivalent with identical electrical and mechanical specifications. Height variation of 0.079" (2.00 mm) is within acceptable tolerance for snap-in mounting applications.

2. 381LX222M050H012 (Cornell Dubilier Electronics) - Upgrade substitute with enhanced temperature rating (3000 Hrs @ 105°C vs. 85°C) and extended operating temperature range (-40°C ~ 105°C). Mechanical dimensions and electrical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance, ensuring regulatory and supply chain continuity.

SLPX222M050A1P3 provides direct functional equivalence to the LLS1H222MELZ. The 2.00 mm height reduction does not affect snap-in mounting compatibility and may provide layout advantages in space-constrained applications. ESR specification (211 mOhm @ 120 Hz) is provided for this part, enabling precise ripple current analysis.

381LX222M050H012 serves as an upgrade substitute when extended thermal performance is required. The elevated temperature rating (105°C vs. 85°C) and extended operating range support applications with higher ambient temperatures or thermal stress. Identical mechanical dimensions to the original part ensure direct board-level compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can SLPX222M050A1P3 be used as a direct replacement for LLS1H222MELZ?

A: Yes. Both parts share identical capacitance (2200 µF), voltage rating (50 V), tolerance (±20%), lead spacing (10.00 mm), diameter (22.00 mm), and package type (radial, can snap-in). The 2.00 mm height difference is within acceptable tolerance for through-hole snap-in applications and does not affect electrical performance or mounting compatibility.

Q: When should 381LX222M050H012 be selected over the other options?

A: Select 381LX222M050H012 when the application requires operation at temperatures above 85°C or when extended thermal lifetime (3000 Hrs @ 105°C) is specified. The expanded operating range (-40°C ~ 105°C) accommodates higher ambient or component-level thermal conditions while maintaining all other electrical and mechanical equivalence.

Q: Are all three parts mechanically interchangeable on the PCB?

A: Yes, with one consideration. SLPX222M050A1P3 has a maximum seated height of 0.984" (25.00 mm), compared to 1.063" (27.00 mm) for both LLS1H222MELZ and 381LX222M050H012. This 2.00 mm difference is acceptable for snap-in mounting and does not affect board-level compatibility. Lead spacing and diameter are identical across all three parts.

Q: What is the significance of the ESR specification for SLPX222M050A1P3?

A: The ESR (Equivalent Series Resistance) of 211 mOhm @ 120 Hz provides quantified information for ripple current calculations and thermal analysis. This specification enables precise circuit performance prediction in applications with defined ripple current requirements. The original LLS1H222MELZ does not provide ESR data in the available specifications.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. All three parts—LLS1H222MELZ, SLPX222M050A1P3, and 381LX222M050H012—are ROHS3 compliant, ensuring regulatory compliance for applications subject to RoHS directives.
