Engineering Selection Recommendations

Direct Equivalents (Recommended Primary Choices):

200USG680MEFC22X35 (Rubycon), 380LX681M200H452 (Cornell Dubilier Electronics), and LLS2D681MELZ (Nichicon) meet all critical electrical parameters with 3000-hour lifetime ratings at 85°C and active product status. All three are ROHS3 compliant. Physical height variations (37.00 mm, 47.00 mm, and 40.00 mm respectively) require mechanical validation for board layout compatibility. Rubycon 200USG680MEFC22X35 offers the most compact height at 37.00 mm.

Upgrade Option:

LGU2D681MELZ (Nichicon) provides enhanced temperature performance with 3000-hour lifetime at 105°C and extended operating range to 105°C. This part is mechanically identical to the original (45.00 mm height) and ROHS3 compliant, making it suitable for applications requiring improved thermal margin.

Higher Voltage Alternative:

SLPX681M220A4P3 (Cornell Dubilier Electronics) operates at 220 V, providing voltage headroom above the original 200 V specification. This part maintains 3000-hour lifetime at 85°C and is ROHS3 compliant. Use only when circuit design permits higher voltage rating.

Reduced Lifetime Options:

380LQ681M200J022 (Cornell Dubilier Electronics), B43305B2687M000 (EPCOS - TDK Electronics), and LPX681M200C7P3 (Cornell Dubilier Electronics) provide 2000-hour, 2000-hour, and 1000-hour lifetimes respectively at 85°C. These parts are suitable only for applications where reduced lifetime is acceptable. All are ROHS3 compliant and active products.

All substitute parts maintain the critical 0.394" (10.00 mm) lead spacing and through-hole mounting configuration required for direct board-level replacement.

Frequently Asked Questions (FAQ)

Q: Can I use a 220 V rated capacitor in place of a 200 V rated capacitor?

A: Yes. SLPX681M220A4P3 operates at 220 V and is electrically compatible with 200 V circuit designs. Higher voltage ratings provide additional safety margin. Verify circuit design permits this substitution.

Q: What is the impact of different physical heights on board compatibility?

A: The substitute parts range from 30.00 mm to 47.00 mm in seated height, compared to the original 45.00 mm. Verify clearance above the capacitor location on the PCB. Shorter parts (30.00 mm to 37.00 mm) are generally preferred for space-constrained designs.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed are ROHS3 compliant. The original ECO-S2DP681BA is REACH Affected; all substitutes are REACH Unaffected.

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

A: Direct equivalents (200USG680MEFC22X35, 380LX681M200H452, LLS2D681MELZ) match the original 3000-hour lifetime at 85°C. The upgrade option LGU2D681MELZ extends lifetime to 3000 hours at 105°C, providing superior thermal performance for demanding applications.

Q: Can I use parts with reduced lifetime ratings?

A: Parts with 2000-hour or 1000-hour lifetimes (380LQ681M200J022, B43305B2687M000, LPX681M200C7P3) are suitable only when application requirements permit reduced operational life. Confirm system design specifications before selection.

Q: Do all substitute parts use the same lead spacing?

A: Yes. All substitute parts maintain 0.394" (10.00 mm) lead spacing, enabling direct PCB footprint compatibility with the original ECO-S2DP681BA.

Q: Which substitute offers the best overall compatibility?

A: 200USG680MEFC22X35 (Rubycon) provides optimal compatibility with matching electrical specifications, active product status, ROHS3 compliance, and the most compact physical height (37.00 mm) for space-constrained applications.
