LLS1J472MELZ Equivalent & Substitute Parts

Part Overview

The LLS1J472MELZ is a 4700 µF, 63 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 at moderate voltage ratings. The part is currently active in production with ROHS3 compliance and maintains a 3000-hour lifetime rating at 85°C operating temperature. Equivalent and substitute parts are identified based on matching electrical specifications (capacitance, voltage rating, tolerance) and mechanical compatibility (lead spacing, mounting type, package configuration).

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1J472MELZ is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 63 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)

Mechanical Compatibility Requirements:

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

Compliance Requirements:

RoHS Status: ROHS3 Compliant (minimum requirement)

All four substitute parts listed meet these criteria. Physical dimensions (diameter and height) may vary within the snap-in package envelope without affecting electrical performance or board-level compatibility, provided lead spacing and mounting type remain constant.

Engineering Selection Recommendations

All five parts listed are ROHS3 compliant and maintain active product status. Selection among these equivalents should be based on:

Nichicon LLS Series (LLS1J472MELZ, LLS1J472MELB): Both parts are manufactured by Nichicon and share identical electrical specifications. The primary difference is physical form factor. The LLS1J472MELZ features a taller, narrower profile (22 mm diameter, 52 mm height), while the LLS1J472MELB uses a shorter, wider profile (30 mm diameter, 30 mm height). Selection depends on available board space and mechanical constraints.

Cornell Dubilier Electronics (CDE) SLPX Series (SLPX472M063C7P3, SLPX472M063E3P3): Both SLPX parts provide specified ESR values (85 mOhm @ 120 Hz) and are electrically equivalent to the main part. The SLPX472M063C7P3 has a 25 mm diameter and 40 mm height, while the SLPX472M063E3P3 has a 30 mm diameter and 30 mm height. Both are suitable for general-purpose applications with identical electrical performance.

Cornell Dubilier Electronics (CDE) 380LX Series (380LX472M063K022): This part offers the highest ripple current rating (4.9 A @ 120 Hz) and specified ESR (80 mOhm @ 120 Hz). It features a 30 mm diameter and 32 mm height. This option is appropriate for applications requiring higher ripple current handling capability.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LLS1J472MELZ with any of the listed parts?

A: Yes. All listed parts meet the critical electrical and mechanical requirements: 4700 µF capacitance, 63 V voltage rating, ±20% tolerance, 3000-hour lifetime at 85°C, 10 mm lead spacing, through-hole mounting, and snap-in package configuration. Physical dimensions vary, so verify available board space before selection.

Q: What is the significance of the different physical dimensions?

A: Physical dimensions (diameter and height) do not affect electrical performance or lead-level compatibility. Differences exist to accommodate various board layout constraints. Verify that the selected part fits within the available mounting envelope on your PCB.

Q: Why do some parts specify ESR and others do not?

A: ESR (Equivalent Series Resistance) is a measured parameter provided by manufacturers when characterized. The absence of a specified ESR value does not indicate inferior performance; it indicates that the manufacturer did not publish this parameter for the LLS1J472MELZ. All parts meet the same lifetime and temperature specifications.

Q: Are there any compliance differences between manufacturers?

A: All listed parts are ROHS3 compliant and REACH unaffected. No compliance differences exist among the options presented.

Q: Can I use a substitute part with different ripple current ratings?

A: Yes, provided your application does not exceed the ripple current specification of the selected part. The 380LX472M063K022 offers higher ripple current capability (4.9 A @ 120 Hz) compared to other options, making it suitable for higher-ripple applications. Verify that your circuit's ripple current does not exceed the selected part's rating.
