Engineering Selection Recommendations

Primary Selection: EKY-500ELL152MLP1S

The EKY-500ELL152MLP1S remains the preferred choice for new designs and ongoing production. This part is active in production status, ROHS3 compliant, and REACH unaffected, ensuring long-term availability and regulatory compliance without material restrictions.

Direct Substitute: EKYB500ELL152MLN3S

The EKYB500ELL152MLN3S is a direct electrical and mechanical equivalent manufactured by Chemi-Con. All critical parameters match the primary part exactly. The only difference is reduced seated height (1.240" vs. 1.457"), which provides improved PCB clearance. This part is active in production, ROHS3 compliant, and REACH unaffected. Higher inventory availability (1532 units) supports supply chain continuity.

Upgrade Alternative: UHE1H152MHD

The UHE1H152MHD is manufactured by Nichicon and meets all electrical and mechanical specifications. However, this part carries a "Not For New Designs" status, indicating it is in end-of-life phase. Additionally, REACH status is listed as affected, which may impose material sourcing restrictions in certain regulatory jurisdictions. This part should be used only when primary and direct substitute options are exhausted. The higher ripple current rating at 120 Hz (2.52 A vs. 1.89 A) indicates improved low-frequency thermal performance.

Height Consideration:

The EKYB500ELL152MLN3S features a 0.217" (5.50mm) reduction in seated height compared to the primary part. Verify PCB clearance constraints before selection. The UHE1H152MHD height (1.398") falls between the two Chemi-Con options.

Frequently Asked Questions (FAQ)

Q: Can EKYB500ELL152MLN3S be used as a direct replacement for EKY-500ELL152MLP1S?

A: Yes. The EKYB500ELL152MLN3S is electrically and mechanically equivalent. All capacitance, voltage, tolerance, lifetime, temperature range, lead spacing, diameter, and impedance specifications match exactly. The reduced height (1.240" vs. 1.457") improves PCB clearance and is not a limitation for substitution.

Q: Why is UHE1H152MHD marked "Not For New Designs"?

A: This designation indicates the part is in end-of-life phase and Nichicon is discontinuing production. While the part meets all electrical and mechanical specifications, it should not be selected for new product designs. Use this part only when primary and direct substitute options are unavailable.

Q: What does "REACH Affected" mean for UHE1H152MHD?

A: REACH Affected status indicates the part may contain substances of concern under European REACH regulations. This may impose material sourcing restrictions or require additional compliance documentation in certain markets. The primary part (EKY-500ELL152MLP1S) and direct substitute (EKYB500ELL152MLN3S) are both REACH Unaffected, making them preferable for applications with strict regulatory requirements.

Q: Does the height difference between substitute parts affect circuit performance?

A: Height differences do not affect electrical performance. The reduced height of EKYB500ELL152MLN3S (1.240") provides additional PCB clearance compared to the primary part (1.457"). Verify clearance constraints in your specific PCB layout before selection.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—EKY-500ELL152MLP1S, EKYB500ELL152MLN3S, and UHE1H152MHD—are ROHS3 compliant, meeting lead-free and hazardous substance restrictions.

Q: What is the difference in ripple current performance between the main part and UHE1H152MHD?

A: At 120 Hz, UHE1H152MHD supports 2.52 A compared to 1.89 A for the main part, representing a 33% improvement in low-frequency ripple current capacity. At 100 kHz, both parts support 3.15 A. This difference indicates improved thermal performance at low frequencies for the Nichicon part.

Q: Can I mix these parts in the same production batch?

A: All three parts are electrically equivalent and can be used interchangeably from a circuit function perspective. However, verify your quality assurance and traceability requirements. If part-level traceability is required, maintain separate inventory and documentation for each manufacturer and series.

Q: Which part should I select for long-term supply security?

A: Select EKYB500ELL152MLN3S. This part is active in production, has higher inventory availability (1532 units), and is manufactured by Chemi-Con, the same manufacturer as the primary part. The direct substitute ensures consistent supply and eliminates cross-manufacturer sourcing complexity.
