LLS1K472MELC Equivalent & Substitute Parts

Part Overview

The LLS1K472MELC is a 4700 µF, 80 V aluminum electrolytic capacitor manufactured by Nichicon in a radial, can snap-in package. This component is rated for 3000 hours at 85°C and operates across the temperature range of -40°C to 85°C. The part is currently active in production with ROHS3 compliance and is suitable for general-purpose applications requiring high-capacitance energy storage in through-hole configurations.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from multiple qualified manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1K472MELC is determined by strict equivalence across the following parameters:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 80 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)
Polarization: Polar (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)

All substitute parts listed meet these core electrical and mechanical requirements. Physical dimensions (diameter and height) may vary within the constraints of the snap-in package form factor, provided that lead spacing and mounting type remain unchanged.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the primary LLS1K472MELC part. Selection among these alternatives should be based on:

Physical footprint compatibility: The LLS1K472MELC (35.00 mm diameter, 32.00 mm height) matches the SLPX472M080H3P3 and 478LBB080M2ED in overall dimensions. The LLS1K472MELB and 380LX472M080K042 share identical diameter and height (30.00 mm and 42.00 mm respectively). The 380LX472M080J052 presents a more compact diameter (25.00 mm) with increased height (52.00 mm).

Manufacturer availability: Nichicon LLS series parts (LLS1K472MELC and LLS1K472MELB) provide continuity within the same manufacturer family. Cornell Dubilier Electronics alternatives (SLPX, 380LX, and 478LBB series) offer cross-manufacturer equivalence with established supply chain presence.

All parts are rated for identical electrical performance within the specified tolerance and operating parameters, ensuring functional interchangeability in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the LLS1K472MELC with any of the listed parts without circuit redesign?

A: Yes, all listed parts are electrically equivalent at 4700 µF, 80 V, ±20% tolerance with identical lifetime and operating temperature specifications. Physical dimensions vary, so verify that the selected substitute fits within your PCB layout constraints and snap-in mounting footprint.

Q: What is the significance of the different physical dimensions among substitute parts?

A: While all parts maintain the same 10.00 mm lead spacing and through-hole mounting type, diameter and height variations reflect different internal construction approaches by manufacturers. The LLS1K472MELC (35.00 mm diameter, 32.00 mm height) and 478LBB080M2ED share identical dimensions. Compact alternatives like the 380LX472M080J052 (25.00 mm diameter, 52.00 mm height) may be preferred in space-constrained designs, while taller variants like the 380LX472M080J052 may require clearance verification above the PCB.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts carry ROHS3 compliance certification, meeting the same regulatory requirements as the primary LLS1K472MELC part.

Q: What is the difference between "Similar" and "Direct" substitute classifications?

A: Classification reflects the degree of parametric alignment. Direct substitutes (SLPX472M080H3P3) match the primary part across all specified electrical and mechanical parameters. Similar substitutes (LLS1K472MELB, 380LX472M080J052, 380LX472M080K042) meet all core electrical requirements but may present dimensional variations. Parametric equivalents (478LBB080M2ED) satisfy functional requirements while potentially offering optimized performance characteristics such as lower ESR.

Q: Can I use these parts interchangeably in high-ripple-current applications?

A: All parts are rated for identical ripple current specifications at 120 Hz and 50 kHz as provided in the main part data. Verify ripple current performance against your specific application frequency and current requirements before final selection.
