Substitute Part Grouping Explanation

Substitution for the ECO-S2GP680BA is determined by the following criteria:

Direct Equivalents maintain identical electrical and mechanical specifications:

Capacitance: 68 µF
Voltage Rating: 400 V
Tolerance: ±20%
Package: Radial, Can - Snap-In
Lead Spacing: 0.394" (10.00 mm)
Operating Temperature: -25°C ~ 85°C
Lifetime: 3000 Hrs @ 85°C

Upgrade Substitutes exceed the original specifications in voltage rating and/or operating temperature while maintaining all other core parameters. These parts provide enhanced performance margins and are suitable for applications where the original 400 V rating is acceptable but higher ratings offer design flexibility.

Engineering Selection Recommendations

Direct Equivalent Selection:

The 380LX680M400H012 (Cornell Dubilier Electronics) and LLS2G680MELY (Nichicon) are direct functional equivalents with identical electrical ratings. Both are active products with ROHS3 compliance. The 380LX680M400H012 maintains the same physical diameter as the original part but has a slightly increased height (1.063" vs. 0.984"). The LLS2G680MELY has a reduced diameter (0.787" vs. 0.866") but matches the original height. Physical fit verification in the target application is required when height or diameter differs from the original specification.

Upgrade Substitute Selection:

The 381LR680M420H012 and 381LR680M450H012 (Cornell Dubilier Electronics) offer enhanced voltage ratings (420 V and 450 V respectively) and extended operating temperature range (-25°C ~ 105°C). The 381LR680M420H012 provides lower ESR (1.95 Ω) compared to the original (2.438 Ω). The LLS2W680MELZ (Nichicon) provides 450 V rating while maintaining the original operating temperature range. All upgrade substitutes are ROHS3 compliant and active products.

Selection between direct equivalents and upgrade substitutes depends on application voltage headroom requirements and thermal operating conditions. Upgrade substitutes are suitable for applications where the original 400 V rating is acceptable but higher voltage margins are beneficial.

Frequently Asked Questions (FAQ)

Q: Can I use a 420 V or 450 V rated capacitor in place of the 400 V ECO-S2GP680BA?

A: Yes. Higher voltage-rated capacitors are electrically compatible in applications designed for 400 V operation. The 420 V and 450 V rated substitutes (381LR680M420H012, 381LR680M450H012, LLS2W680MELZ) provide additional voltage margin and are suitable direct replacements from an electrical standpoint.

Q: What is the difference between direct equivalents and upgrade substitutes?

A: Direct equivalents (380LX680M400H012, LLS2G680MELY) match the original 400 V rating and 3000 Hrs @ 85°C lifetime specification. Upgrade substitutes exceed these specifications with higher voltage ratings (420 V or 450 V) and/or extended temperature ratings (105°C). All are functionally compatible with the original design.

Q: Does the physical size difference matter?

A: Physical dimensions must be verified against the PCB layout and mechanical constraints of the target application. The LLS2G680MELY has a smaller diameter (0.787" vs. 0.866"), while the 380LX680M400H012 has increased height (1.063" vs. 0.984"). The 381LR and LLS2W series maintain the original 0.866" diameter and 0.984" height.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the lead spacing requirement?

A: All substitute parts maintain the original 0.394" (10.00 mm) lead spacing, ensuring PCB footprint compatibility.
