Engineering Selection Recommendations

Direct Substitutes with Identical Dimensions: 381LX682M016H012 (Cornell Dubilier Electronics) and LGU1C682MELZ (Nichicon) provide direct mechanical and electrical compatibility with the ECO-S1CA682BA. Both parts maintain the 0.866" diameter and 1.063" maximum height, ensuring PCB layout compatibility without modification. Both are ROHS3 compliant and carry active product status.

Enhanced Lifetime Option: LGY1C682MELZ25 (Nichicon) offers the same mechanical footprint as the original part with an extended lifetime specification of 5000 hours at 105°C, compared to the standard 3000 hours. This part is suitable for applications requiring improved reliability margins.

Compact Diameter Alternative: 16MXG6800MEFCSN20X25 (Rubycon) provides electrical equivalence with a reduced diameter of 0.787" (20.00 mm) versus the original 0.866" (22.00 mm). This part is suitable for space-constrained applications where the smaller footprint is acceptable.

Reduced Height Option: SLP682M016A1P3 (Cornell Dubilier Electronics) maintains the original diameter but reduces the seated height to 0.984" (25.00 mm) from 1.063" (27.00 mm). This part is applicable where vertical clearance is limited.

Dimensional Variant: 381LX682M016K202 (Cornell Dubilier Electronics) presents a larger diameter of 1.181" (30.00 mm) with reduced height of 0.866" (22.00 mm). This configuration requires mechanical design review to confirm PCB layout compatibility.

All substitute parts maintain the required 0.394" (10.00 mm) lead spacing, through-hole mounting type, and -40°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions?

A: Physical dimensions must be verified against your PCB layout and mechanical constraints. While all substitute parts maintain the 0.394" (10.00 mm) lead spacing required for through-hole mounting, variations in diameter and height may affect board space utilization. Parts with reduced diameter (16MXG6800MEFCSN20X25) or height (SLP682M016A1P3) are suitable for space-constrained designs. Parts with increased diameter (381LX682M016K202) require confirmation that the larger footprint does not conflict with adjacent components.

Q: What is the difference between the 3000-hour and 5000-hour lifetime specifications?

A: Lifetime specification indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches the tolerance limit. The LGY1C682MELZ25 offers 5000 hours at 105°C compared to 3000 hours for other substitutes. This extended lifetime provides additional design margin for applications with stringent reliability requirements or elevated operating temperatures.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1CA682BA does not specify RoHS status due to its obsolete product status. All substitute parts meet current environmental compliance requirements.

Q: Can I interchange parts with different ESR values?

A: ESR (Equivalent Series Resistance) values are provided only for the ECO-S1CA682BA (85 mOhm @ 120 Hz) and SLP682M016A1P3 (98 mOhm @ 120 Hz). Other substitute parts do not specify ESR in the provided data. ESR affects ripple current handling and thermal performance. If ESR is critical to your application, verify the specific value with the manufacturer before selection.

Q: What is the significance of lead spacing in capacitor substitution?

A: Lead spacing of 0.394" (10.00 mm) is maintained across all substitute parts and the original component. This spacing is critical for through-hole PCB mounting compatibility. All parts listed are compatible with standard 10 mm lead spacing on PCBs designed for the ECO-S1CA682BA.
