LLS1E822MELZ Equivalent & Substitute Parts

Part Overview

The LLS1E822MELZ is an 8200 µF, 25 V aluminum electrolytic capacitor in a radial, can snap-in package manufactured by Nichicon. This component is classified as Active product status and is designed for general-purpose applications requiring high capacitance energy storage in compact form factors. Equivalent and substitute parts are identified when identical electrical specifications (capacitance, voltage rating, tolerance, lifetime) and compatible mechanical parameters (package type, lead spacing, mounting configuration) are maintained across different manufacturers or product series.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1E822MELZ is determined by strict equivalence across the following criteria:

Capacitance value: 8200 µF (exact match required)
Voltage rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime specification: 3000 Hrs @ 85°C (exact match required)
Operating temperature range: -40°C ~ 85°C (exact match required)
Package configuration: Radial, Can - Snap-In (exact match required)
Lead spacing: 0.394" (10.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)
Regulatory compliance: ROHS3 Compliant (minimum requirement)

Two substitute parts meet these criteria: LLS1E822MELA (Nichicon, same series) and 380LX822M025J012 (Cornell Dubilier Electronics). Both maintain identical electrical performance specifications and mechanical compatibility with the primary part number.

Engineering Selection Recommendations

All three parts—LLS1E822MELZ, LLS1E822MELA, and 380LX822M025J012—are Active product status components with ROHS3 compliance and REACH Unaffected regulatory standing. Selection between these equivalents should be based on:

Physical space constraints: The LLS1E822MELZ features a smaller diameter (22.00 mm) and greater height (37.00 mm) compared to LLS1E822MELA and 380LX822M025J012, which both measure 25.00 mm diameter and 27.00 mm height. PCB layout requirements will determine which form factor is appropriate.

Ripple current performance: The 380LX822M025J012 provides higher ripple current ratings (3.6 A @ 120 Hz, 4.1 A @ 20 kHz) compared to the Nichicon variants, making it suitable for applications with elevated AC current demands.

Manufacturer availability: Inventory levels vary across suppliers. Selection may be influenced by stock availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can LLS1E822MELA be used as a direct replacement for LLS1E822MELZ?

A: Yes. Both parts are manufactured by Nichicon, share identical electrical specifications (8200 µF, 25 V, ±20%, 3000 Hrs @ 85°C), and use the same package type (Radial, Can - Snap-In) with matching lead spacing (10.00 mm). The primary difference is physical dimension: LLS1E822MELA is smaller in diameter (25.00 mm vs. 22.00 mm) and shorter in height (27.00 mm vs. 37.00 mm). Verify PCB layout compatibility before substitution.

Q: Is 380LX822M025J012 from Cornell Dubilier Electronics electrically equivalent?

A: Yes. The 380LX822M025J012 meets all electrical equivalence criteria: 8200 µF capacitance, 25 V rating, ±20% tolerance, and 3000 Hrs @ 85°C lifetime. It maintains identical lead spacing (10.00 mm) and through-hole mounting configuration. Physical dimensions match LLS1E822MELA (25.00 mm diameter, 27.00 mm height). The CDE part offers higher ripple current performance.

Q: What are the mechanical compatibility constraints?

A: All three parts use identical lead spacing (0.394" / 10.00 mm) and through-hole mounting, ensuring PCB footprint compatibility. However, physical dimensions differ: LLS1E822MELZ is taller and narrower, while LLS1E822MELA and 380LX822M025J012 are shorter and wider. Verify available board space and component clearance before selection.

Q: Are there any compliance or regulatory differences?

A: All three parts are ROHS3 Compliant and REACH Unaffected. No regulatory barriers exist for cross-substitution. The 380LX822M025J012 carries MSL 1 (Unlimited) moisture sensitivity rating, while the Nichicon parts list MSL as Not Applicable.

Q: Which part should be selected for high ripple current applications?

A: The 380LX822M025J012 provides the highest ripple current ratings (3.6 A @ 120 Hz, 4.1 A @ 20 kHz) and includes specified ESR (65 mOhm @ 120 Hz). For applications requiring maximum ripple current handling, this part is the preferred selection among the three equivalents.
