Equivalent & Substitute Parts for LLS1J682MELB

Part Overview

The LLS1J682MELB is a 6800 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 at moderate voltage ratings with a 3000-hour lifetime at 85°C. The part is currently active in production and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications and mechanical compatibility within the through-hole radial can snap-in form factor.

Substitute Part Grouping Explanation

Substitution eligibility for the LLS1J682MELB is determined by strict equivalence across the following critical parameters:

Capacitance: 6800 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)
Polarization: Polar (exact match required)
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)

All identified substitute parts meet these criteria. Variations in physical dimensions (diameter and height) and ripple current specifications are permitted within the snap-in package family, as these do not affect electrical equivalence or board-level compatibility when lead spacing and mounting type remain constant.

Engineering Selection Recommendations

All four parts—LLS1J682MELB, LLS1J682MELC, SLPX682M063E7P3, and SLPX682M063C9P3—are electrically equivalent and mechanically compatible for through-hole snap-in mounting applications. Each part is active in production status and ROHS3 compliant, meeting current regulatory requirements.

Selection between Nichicon and Cornell Dubilier Electronics variants should be based on:

Availability and lead time requirements
Existing supply chain qualification
Physical space constraints on the PCB, as diameter and height vary across the substitute group
Manufacturer preference or contractual requirements

The dimensional variations among these parts do not affect electrical performance or functional equivalence. All parts maintain identical capacitance, voltage rating, tolerance, lifetime rating, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can LLS1J682MELC be used as a direct replacement for LLS1J682MELB?

A: Yes. Both parts are manufactured by Nichicon with identical electrical specifications: 6800 µF, 63 V, ±20% tolerance, 3000 Hrs @ 85°C lifetime, and -40°C ~ 85°C operating range. The primary difference is physical dimensions; LLS1J682MELC has a larger diameter (35.00 mm vs. 30.00 mm) and shorter height (32.00 mm vs. 42.00 mm). Verify PCB layout space before substitution.

Q: Are Cornell Dubilier Electronics SLPX series parts equivalent to Nichicon LLS parts?

A: Yes. SLPX682M063E7P3 and SLPX682M063C9P3 are electrically equivalent to the LLS1J682MELB. All critical electrical parameters match exactly. Physical dimensions differ; verify board-level fit before implementation.

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

A: Physical dimensions (diameter and height) vary within the radial snap-in can family while maintaining the same 10.00 mm lead spacing and through-hole mounting compatibility. These dimensional differences do not affect electrical equivalence. Selection should account for available PCB space and mechanical clearance requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. LLS1J682MELB, LLS1J682MELC, SLPX682M063E7P3, and SLPX682M063C9P3 are all ROHS3 compliant and suitable for applications requiring regulatory compliance.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that PCB layout accommodates the physical dimensions of the selected part. All parts share identical electrical specifications, lead spacing, and mounting type. Verify mechanical fit and confirm any manufacturer-specific qualification requirements before implementation.
