Engineering Selection Recommendations

Recommended Direct Substitutes:

UCS2D331MHD (Nichicon UCS Series) is the primary direct substitute for the EKXG201ELL331MMP1S. This part maintains identical electrical specifications (330 µF, ±20%, 200 V), matching lifetime rating (10000 hours @ 105°C), and compatible mechanical dimensions (18.00 mm diameter, 7.50 mm lead spacing). The UCS2D331MHD is currently in active production status with 4350 units in stock. ROHS3 compliance and REACH Unaffected status align with the original part. Height variation (37.00 mm vs. 35.50 mm) is within acceptable through-hole PCB tolerances.

Enhanced Performance Alternatives:

UCY2D331MHD6 (Nichicon UCY Series) offers extended lifetime (12000 hours @ 105°C) compared to the original specification. This part maintains identical electrical parameters and lead spacing (7.50 mm) with a reduced can diameter (18.00 mm) and lower seated height (33.00 mm), providing improved PCB space efficiency. The part is in active production with 1498 units available. REACH Affected status requires compliance verification in applications subject to REACH regulations.

UCY2D331MHD (Nichicon UCY Series) provides the same extended lifetime benefit (12000 hours @ 105°C) as the UCY2D331MHD6 variant. This part features a smaller can diameter (16.00 mm) but increased height (41.50 mm). Lead spacing remains compatible at 7.50 mm. Active production status with 1154 units in stock. REACH Affected status applies.

Not Recommended for New Designs:

UPW2D331MRD (Nichicon UPW Series) is marked as Obsolete and should not be selected for new designs. Although electrically compatible, this part has a different lead spacing (10.00 mm vs. 7.50 mm) and larger can diameter (22.00 mm), requiring PCB redesign. Reduced ripple current ratings and shorter lifetime (8000 hours) further limit its suitability.

UVY2D331MHD (Nichicon UVY Series) is designated as Not For New Designs. This part exhibits significantly reduced ripple current capacity and the shortest lifetime rating (2000 hours @ 105°C) among all alternatives, making it unsuitable for applications requiring the original part's performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can UCS2D331MHD be used as a direct replacement for EKXG201ELL331MMP1S without PCB modification?

A: Yes. The UCS2D331MHD maintains identical electrical specifications, lead spacing (7.50 mm), and can diameter (18.00 mm). The height difference of 1.50 mm (37.00 mm vs. 35.50 mm) is within standard through-hole PCB clearance tolerances and does not require PCB redesign.

Q: What is the advantage of selecting UCY2D331MHD6 over the original EKXG201ELL331MMP1S?

A: The UCY2D331MHD6 provides a 20% increase in lifetime rating (12000 hours vs. 10000 hours @ 105°C) while occupying less vertical PCB space (33.00 mm vs. 35.50 mm height). This combination offers improved reliability margins and enhanced layout flexibility. The part is in active production with adequate inventory.

Q: Why is UPW2D331MRD not recommended despite electrical compatibility?

A: The UPW2D331MRD is marked as Obsolete and features a different lead spacing (10.00 mm vs. 7.50 mm), requiring PCB redesign. Additionally, it exhibits reduced ripple current capacity and shorter lifetime (8000 hours), making it unsuitable for applications requiring the original part's performance specifications.

Q: Are there REACH compliance considerations when selecting a substitute?

A: Yes. The original EKXG201ELL331MMP1S is REACH Unaffected. Substitutes UCS2D331MHD and UPW2D331MRD maintain REACH Unaffected status. However, UCY2D331MHD6 and UCY2D331MHD are marked as REACH Affected. Applications subject to REACH regulations must verify compliance requirements before selecting these alternatives.

Q: Can UCY2D331MHD be used in place of UCY2D331MHD6?

A: Both parts offer identical lifetime ratings (12000 hours @ 105°C) and electrical specifications. However, they differ in physical dimensions: UCY2D331MHD has a smaller diameter (16.00 mm) but greater height (41.50 mm) compared to UCY2D331MHD6 (18.00 mm diameter, 33.00 mm height). Selection depends on available PCB space constraints. Both require REACH compliance verification.

Q: What is the minimum lifetime requirement for selecting a substitute?

A: The original EKXG201ELL331MMP1S specifies 10000 hours @ 105°C. Substitutes must meet or exceed this lifetime rating. UCS2D331MHD matches this specification exactly. UCY2D331MHD6 and UCY2D331MHD exceed it with 12000 hours. UPW2D331MRD falls below at 8000 hours and is not recommended. UVY2D331MHD at 2000 hours is unsuitable for equivalent performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (UCS2D331MHD, UCY2D331MHD6, UCY2D331MHD, UPW2D331MRD, and UVY2D331MHD) are ROHS3 Compliant, matching the original EKXG201ELL331MMP1S compliance status.
