Engineering Selection Recommendations

For Active Production Designs: The EKY-160ELL682ML40S is the primary substitute for the KY16VB682M16X40LL. Both parts are manufactured by Chemi-Con, belong to the KY series, and maintain identical electrical and mechanical specifications. The EKY-160ELL682ML40S offers the additional advantage of ROHS3 compliance, making it suitable for applications with regulatory requirements. The height difference of 0.059" (1.50 mm) is within acceptable tolerances for through-hole PCB layouts.

For Legacy or Existing Designs: The UHE1C682MHD from Nichicon is a parametric equivalent that maintains all critical electrical specifications and mechanical compatibility. However, this part carries a "Not For New Designs" status and is subject to REACH regulations. The ripple current at 120 Hz is slightly lower (3.264 A versus 3.468 A), which may be acceptable depending on circuit requirements. This part is suitable only for replacement or maintenance of existing assemblies.

Compliance Considerations: If RoHS3 compliance is required, the EKY-160ELL682ML40S is the appropriate selection. The original KY16VB682M16X40LL is RoHS non-compliant. For applications subject to REACH regulations, the EKY-160ELL682ML40S is preferred over the UHE1C682MHD.

Frequently Asked Questions (FAQ)

Q: Can the EKY-160ELL682ML40S be used as a direct replacement for the KY16VB682M16X40LL?

A: Yes. Both parts share identical capacitance (6800 µF), voltage rating (16 V), tolerance (±20%), operating temperature range, lifetime rating, impedance, and ripple current specifications at 100 kHz. The height difference of 0.059" (1.50 mm) does not affect through-hole PCB compatibility. Both are manufactured by Chemi-Con and belong to the KY series.

Q: What is the difference between the KY16VB682M16X40LL and the UHE1C682MHD?

A: The primary differences are manufacturer (Chemi-Con versus Nichicon), series designation (KY versus UHE), product status (Active versus Not For New Designs), and ripple current at 120 Hz (3.468 A versus 3.264 A). All other electrical and mechanical parameters are equivalent. The UHE1C682MHD is subject to REACH regulations, while the KY16VB682M16X40LL is REACH Unaffected.

Q: Is the height difference between KY16VB682M16X40LL (40.00 mm) and EKY-160ELL682ML40S (41.50 mm) significant?

A: The 1.50 mm height difference is within standard tolerances for through-hole component placement and does not affect PCB assembly compatibility. Both parts use identical lead spacing (7.50 mm) and diameter (16.00 mm), ensuring proper fit in existing PCB footprints.

Q: Why is the UHE1C682MHD marked "Not For New Designs"?

A: This designation indicates that Nichicon has discontinued active development and promotion of this part for new applications. The part remains available for replacement and maintenance of existing designs. For new product development, the EKY-160ELL682ML40S is the recommended selection.

Q: Are there any ripple current differences that affect circuit performance?

A: The UHE1C682MHD has a ripple current rating of 3.264 A at 120 Hz, compared to 3.468 A for both the KY16VB682M16X40LL and EKY-160ELL682ML40S. This 0.204 A difference is approximately 5.9% lower. Both the KY16VB682M16X40LL and EKY-160ELL682ML40S maintain identical ripple current at 100 kHz (4.08 A). Circuit thermal analysis should confirm acceptability of the lower 120 Hz rating if the UHE1C682MHD is selected.

Q: Which part should be selected for RoHS3 compliance?

A: The EKY-160ELL682ML40S is ROHS3 Compliant. The KY16VB682M16X40LL is RoHS non-compliant, and the UHE1C682MHD is ROHS3 Compliant but carries a "Not For New Designs" status. For new designs requiring RoHS3 compliance, the EKY-160ELL682ML40S is the appropriate selection.

Q: What is the difference between REACH Unaffected and REACH Affected status?

A: REACH Unaffected indicates the part is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. REACH Affected indicates the part may contain substances of concern and is subject to REACH compliance requirements. The KY16VB682M16X40LL and EKY-160ELL682ML40S are REACH Unaffected, while the UHE1C682MHD is REACH Affected.
