LLS2D471MELY Equivalent & Substitute Parts

Part Overview

The LLS2D471MELY is a 470 µF, 200 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is designed for general-purpose applications requiring stable capacitance performance over extended operational life. The part is currently active in production with 2370 units in stock. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or specific performance characteristics aligned with the electrical and mechanical parameters of the original specification.

Substitute Part Grouping Explanation

Substitute parts for the LLS2D471MELY are qualified based on strict electrical and mechanical compatibility criteria. All substitute candidates must match the following core parameters:

Capacitance: 470 µF (exact match)
Voltage Rating: 200 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)
Package Type: Radial, Can - Snap-In (exact match)
Mounting Type: Through Hole (exact match)
Lead Spacing: 0.394" (10.00 mm) (exact match)
RoHS Status: ROHS3 Compliant (exact match)

All three substitute parts meet these criteria. Physical dimensions (diameter and height) may vary within acceptable mechanical tolerances for snap-in mounting applications. Ripple current ratings and ESR values are provided for performance comparison but do not disqualify substitution when core parameters align.

Engineering Selection Recommendations

All three substitute parts are active products with full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the LLS2D471MELY. Selection among these alternatives should be based on:

PCB layout constraints: The LLS2D471MELZ and SLPX471M200A3P3 feature reduced height (30 mm) compared to the original LLS2D471MELY (35 mm), suitable for space-constrained applications. The 380LX471M200J022 has intermediate height (32 mm) with larger diameter (25 mm).
Inventory availability: The 380LX471M200J022 offers the highest stock level (3660 units), followed by LLS2D471MELZ (1634 units) and SLPX471M200A3P3 (2680 units).
Manufacturer continuity: The LLS2D471MELZ maintains Nichicon sourcing, identical to the original part. The 380LX471M200J022 and SLPX471M200A3P3 are Cornell Dubilier Electronics alternatives.

All parts maintain identical electrical specifications and are mechanically compatible with standard snap-in mounting footprints.

Frequently Asked Questions (FAQ)

Q: Can LLS2D471MELZ be used as a direct replacement for LLS2D471MELY?

A: Yes. Both parts are manufactured by Nichicon with identical electrical specifications (470 µF, 200 V, ±20%, 3000 Hrs @ 85°C). Physical dimensions differ slightly (22 mm diameter, 30 mm height versus 20 mm diameter, 35 mm height), but both use standard 10 mm lead spacing and snap-in mounting. Verify PCB layout clearance before substitution.

Q: What are the key differences between Nichicon and Cornell Dubilier Electronics alternatives?

A: Electrical performance is equivalent across all parts. Physical dimensions vary: Nichicon LLS2D471MELZ is 22 mm diameter × 30 mm height; CDE 380LX471M200J022 is 25 mm diameter × 32 mm height; CDE SLPX471M200A3P3 is 22 mm diameter × 30 mm height. All maintain 10 mm lead spacing and snap-in compatibility.

Q: Are there any compliance or certification differences?

A: All parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity levels differ: LLS2D471MELZ and SLPX471M200A3P3 are not applicable; 380LX471M200J022 is MSL 1 (unlimited). This does not affect substitution for general-purpose applications.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: All parts meet the 3000 Hrs @ 85°C lifetime specification. Ripple current ratings vary slightly (1.9 A to 2.03 A @ 120 Hz). Verify application ripple current requirements against the specific part's rated performance before final selection.

Q: What mounting considerations apply to these snap-in capacitors?

A: All parts use through-hole radial snap-in mounting with 10 mm lead spacing. Physical diameter and height variations require PCB layout verification. Snap-in mounting is compatible with standard PCB footprints designed for this package type.
