Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LLS2C681MELY is determined by the following criteria:

Primary Matching Parameters:

• Capacitance: 680 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.394" (10.00mm) (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime: 3000 Hrs @ 85°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 160 V
• Physical Dimensions (Diameter, Height): Variations permitted within mechanical envelope constraints
• ESR and Ripple Current: Variations permitted provided electrical performance is maintained

Two substitute parts meet these criteria:

LLS2D681MELZ (Nichicon): Matches all primary parameters with rated voltage of 200 V, providing higher voltage margin. Diameter increases to 0.866" (22.00mm) with identical height and lead spacing.

380LX681M160H042 (Cornell Dubilier Electronics): Matches all primary parameters including 160 V voltage rating. Diameter increases to 0.866" (22.00mm) and height to 1.654" (42.00mm). ESR specified at 296mOhm @ 120Hz.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full compliance with ROHS3 and REACH regulations, ensuring regulatory compatibility across substitution options.

LLS2D681MELZ Selection: This Nichicon substitute provides identical electrical performance to the primary part with elevated voltage rating (200 V vs. 160 V). The increased diameter (22.00mm vs. 20.00mm) requires verification of available PCB space. This option is suitable when higher voltage margin is required or when Nichicon supply continuity is prioritized.

380LX681M160H042 Selection: This Cornell Dubilier Electronics substitute matches the original voltage rating (160 V) and maintains identical lead spacing. The increased diameter (22.00mm) and height (42.00mm vs. 40.00mm) require PCB layout verification. This option is suitable when voltage rating equivalence and manufacturer diversification are required.

Selection between substitutes depends on available mechanical envelope in the target application and manufacturer preference for supply chain resilience.

Frequently Asked Questions (FAQ)

Q: Can LLS2D681MELZ be used as a direct replacement for LLS2C681MELY?

A: LLS2D681MELZ is electrically compatible as a substitute. Both parts share identical capacitance (680 µF), tolerance (±20%), package type (Radial, Can - Snap-In), lead spacing (10.00mm), and thermal specifications (3000 Hrs @ 85°C). The substitute has higher voltage rating (200 V vs. 160 V) and larger diameter (22.00mm vs. 20.00mm). PCB layout must accommodate the increased diameter.

Q: What is the difference between LLS2C681MELY and 380LX681M160H042?

A: Both parts share identical capacitance (680 µF), voltage rating (160 V), tolerance (±20%), and thermal life (3000 Hrs @ 85°C). The primary differences are manufacturer (Nichicon vs. Cornell Dubilier Electronics), diameter (20.00mm vs. 22.00mm), and height (40.00mm vs. 42.00mm). Lead spacing remains identical at 10.00mm.

Q: Are all three parts ROHS3 compliant?

A: Yes. LLS2C681MELY, LLS2D681MELZ, and 380LX681M160H042 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the impact of increased voltage rating in LLS2D681MELZ?

A: The 200 V rating in LLS2D681MELZ provides additional voltage margin compared to the 160 V primary part. This does not affect electrical performance in circuits designed for 160 V operation. The substitute is suitable for applications where voltage headroom is beneficial.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability requires verification of mechanical fit. LLS2C681MELY has a smaller diameter (20.00mm) compared to both substitutes (22.00mm). The 380LX681M160H042 also has increased height (42.00mm vs. 40.00mm). PCB layout and available space must be confirmed before substitution.

Q: What is the lead spacing for all three parts?

A: All three parts maintain identical lead spacing of 0.394" (10.00mm), ensuring compatibility with existing PCB footprints designed for the LLS2C681MELY.
