Engineering Selection Recommendations

All listed substitute parts meet the critical electrical and mechanical parameters required for direct substitution with LLS1V682MELZ. Selection among equivalents should be based on the following factors:

Nichicon LGU1V682MELZ: Select when extended operating temperature range (-40°C ~ 105°C) and elevated temperature lifetime (3000 Hrs @ 105°C) are required. Identical physical dimensions to the primary part. Lower ripple current rating (2.41 A @ 120 Hz) compared to LLS1V682MELZ.

Nichicon LLS1V682MELA: Select when alternative physical dimensions are acceptable. Larger diameter (0.984" vs 0.866") and shorter height (1.260" vs 1.654") within the same series. Ripple current performance (2.89 A @ 120 Hz) is comparable to primary part.

Cornell Dubilier SLPX682M035A7P3: Select when CDE manufacturer preference is required. Identical diameter to primary part (0.866"). Slightly shorter height (1.575" vs 1.654"). Specified ESR of 78 mOhm @ 120 Hz. Ripple current matches primary part (2.97 A @ 120 Hz).

Cornell Dubilier 380LX682M035J022: Select when alternative physical dimensions and lower ESR (69 mOhm @ 120 Hz) are acceptable. Larger diameter (0.984") and shorter height (1.260"). Note: MSL rating of 1 (Unlimited) differs from primary part.

Cornell Dubilier SLPX682M035C3P3: Select when compact height (1.181") is required. Larger diameter (0.984"). Specified ESR of 78 mOhm @ 120 Hz. Higher ripple current capability (2.89 A @ 120 Hz).

Cornell Dubilier SLPX682M035E1P3: Select when maximum ripple current handling (3.09 A @ 120 Hz) is required. Largest diameter (1.181") and compact height (0.984"). Specified ESR of 78 mOhm @ 120 Hz.

All substitute parts are Active status and ROHS3 compliant. All are rated for 3000 Hrs @ 85°C minimum lifetime.

Frequently Asked Questions (FAQ)

Q: Can LGU1V682MELZ replace LLS1V682MELZ in all applications?

A: LGU1V682MELZ meets all critical electrical parameters and physical dimensions. The primary difference is extended operating temperature range (-40°C ~ 105°C vs -40°C ~ 85°C) and higher temperature lifetime rating (3000 Hrs @ 105°C). It is suitable for replacement in applications where the original operating temperature range is sufficient. Lower ripple current (2.41 A @ 120 Hz) should be verified against circuit requirements.

Q: What is the impact of physical dimension differences among substitute parts?

A: All substitute parts maintain the same lead spacing (0.394" / 10.00mm) and snap-in package type, ensuring PCB footprint compatibility. Variations in diameter and height affect board layout space. Parts with larger diameters or different heights may require layout verification to confirm clearance with adjacent components.

Q: Are Cornell Dubilier parts direct equivalents to Nichicon parts?

A: Cornell Dubilier SLPX and 380LX series parts meet all critical electrical specifications (6800 µF, 35 V, ±20%, 3000 Hrs @ 85°C) and mechanical requirements (lead spacing, snap-in package). They are functionally equivalent. Differences exist in ESR specifications and physical dimensions. Selection depends on design requirements and manufacturer preference.

Q: What does ESR specification mean for capacitor selection?

A: Equivalent Series Resistance (ESR) affects ripple current handling and heat dissipation. Lower ESR values indicate better high-frequency performance. SLPX and 380LX series parts specify ESR values (69–78 mOhm @ 120 Hz), while LLS and LGU series do not provide ESR data in the specifications. If ESR is a critical design parameter, CDE parts provide explicit values.

Q: Can parts with different physical dimensions be used interchangeably on the same PCB?

A: Lead spacing and snap-in mounting type are identical across all parts, allowing PCB footprint compatibility. However, variations in diameter and height must be verified against board layout constraints and clearance requirements with surrounding components before substitution.

Q: Are all substitute parts in stock?

A: Inventory availability varies. Refer to current stock levels: LGU1V682MELZ (1631 Pcs), LLS1V682MELA (1878 Pcs), SLPX682M035A7P3 (3913 Pcs), 380LX682M035J022 (3542 Pcs), SLPX682M035C3P3 (10391 Pcs), SLPX682M035E1P3 (2964 Pcs).
