Engineering Selection Recommendations

Direct substitutes with active product status and matching electrical specifications include 381LQ561M250J032, 381LX561M250J452, B43254F2567M, LGN2E561MELA35, LGU2E561MELA, and LGW2E561MELA35. All direct substitutes maintain 560 µF capacitance, 250 V voltage rating, ±20% tolerance, and through-hole radial snap-in packaging.

Parts with 3000-hour lifetime ratings at 105°C (381LX561M250J452, B43254F2567M, LGN2E561MELA35, LGU2E561MELA, LGW2E561MELA35, 381LR561M250A012, and 381LR561M250K022) provide equivalent or superior operational longevity compared to the original ECO-S2EB561CA.

Similar parts (381LQ561M250H452, 381LQ561M250K012, 381LR561M250A012, 381LR561M250K022) maintain core electrical parameters but vary in case diameter and height. These are suitable where PCB layout accommodates dimensional variations.

All substitute candidates carry RoHS3 compliance or REACH unaffected status, supporting modern manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can 381LQ561M250J032 replace ECO-S2EB561CA directly?

A: 381LQ561M250J032 matches all core electrical parameters (560 µF, 250 V, ±20% tolerance) and packaging (radial snap-in, through-hole). The primary difference is reduced lifetime (2000 hours vs. 3000 hours at 105°C). Direct substitution is electrically valid; lifetime consideration depends on application requirements.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes maintain identical case diameter (0.984" / 25.00 mm) and lead spacing (0.394" / 10.00 mm). Similar substitutes vary in case diameter or height while preserving electrical equivalence. Similar parts require PCB layout verification before implementation.

Q: Does ESR variation affect substitution suitability?

A: ESR differences (296 mOhm vs. 266 mOhm) represent minor variations within acceptable operating parameters for general-purpose applications. Both values support the specified ripple current ratings and thermal performance.

Q: Are all active substitutes RoHS compliant?

A: All active substitute parts listed carry RoHS3 compliance or REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which substitute offers the best height compatibility with the original?

A: LGW2E561MELA35 provides the closest height match at 1.378" (35.00 mm) compared to the original 1.772" (45.00 mm). 381LQ561M250J032 and LGN2E561MELA35 offer 1.457" (37.00 mm) height, also suitable for space-constrained layouts.

Q: Can I use 381LR561M250K022 as a substitute?

A: 381LR561M250K022 maintains electrical equivalence (560 µF, 250 V, ±20%) and 3000-hour lifetime. However, case diameter is 1.181" (30.00 mm) versus the original 0.984" (25.00 mm), requiring PCB layout verification for mechanical fit.
