Engineering Selection Recommendations

For Direct Replacement (Identical Footprint and Performance): Select 381LX682M050A022 (Cornell Dubilier Electronics). This part maintains the original 35.00 mm diameter and 32.00 mm height, matching the ECO-S1HA682EA physical footprint exactly. It is ROHS3 compliant and active in production with 4910 units in stock.

For Enhanced Reliability: Select LGY1H682MELC30 (Nichicon). This upgrade substitute provides 5000-hour lifetime at 105°C compared to the original 3000 hours, while maintaining identical physical dimensions (35.00 mm diameter, 32.00 mm height). It is ROHS3 compliant and active in production.

For Space-Constrained Applications: Select SLP682M050E5P3 (Cornell Dubilier Electronics). This part reduces the case diameter to 30.00 mm while maintaining the 35.00 mm height, providing a more compact footprint. It maintains 3000-hour lifetime and is ROHS3 compliant.

For Reduced Height Requirements: Select SLP682M050H3P3 (Cornell Dubilier Electronics). This part reduces the case height to 30.00 mm while maintaining the 35.00 mm diameter. It maintains 3000-hour lifetime and is ROHS3 compliant.

All recommended substitutes are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance and long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different case diameter or height? A: Yes, provided the new dimensions fit within your PCB layout and mechanical constraints. All listed substitutes maintain the 0.394" (10.00 mm) lead spacing and through-hole mounting type, ensuring electrical compatibility. Physical footprint changes require verification against your specific board design.

Q: What is the minimum acceptable lifetime for a substitute? A: The original ECO-S1HA682EA specifies 3000 hours at 105°C. Substitutes with 1000-hour or 2000-hour ratings are electrically compatible but may have reduced operational lifespan in high-temperature environments. For applications requiring extended service life, select parts with 3000-hour or higher ratings.

Q: Are all substitute parts RoHS compliant? A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1HA682EA is obsolete and does not carry RoHS certification. Substitution with active, compliant parts ensures regulatory alignment for new designs and ongoing production.

Q: Does ESR variation affect circuit performance? A: ESR differences within the 46–85.33 mOhm range are acceptable for general-purpose applications. The original part specifies 46 mOhm ESR. Substitutes with higher ESR values (such as 688LMB050M2ED at 85.33 mOhm) remain functionally equivalent but may exhibit slightly higher ripple current dissipation. For noise-sensitive applications, prioritize parts with lower ESR values.

Q: Can I substitute a part with lower ripple current rating? A: Ripple current ratings are application-dependent. Ensure the substitute part's ripple current rating meets or exceeds your circuit's actual ripple current demand at both 120 Hz and the relevant high-frequency operating point. Undersizing ripple current capacity may result in premature capacitor failure.

Q: What is the difference between "Direct," "Upgrade," "Similar," and "Parametric Equivalent" classifications? A: Direct substitutes match the original part's electrical and physical specifications closely. Upgrade substitutes offer enhanced performance (such as longer lifetime) while maintaining compatibility. Similar substitutes meet all critical electrical parameters but may have allowable variations in physical dimensions or ESR. Parametric equivalents match all critical electrical specifications with identical or near-identical physical footprints.
