Engineering Selection Recommendations

Both substitute parts satisfy the electrical and mechanical requirements for direct replacement of the ULD2D180MPD.

EKXF201ELL180MJC5S (Chemi-Con): This part carries Active product status, indicating ongoing manufacturer support and availability. It demonstrates higher ripple current capability at 100 kHz (282.5 mA versus 214.7 mA in the original), providing additional performance margin. The seated height is 0.551" (14.00 mm), which is 0.02" lower than the original, ensuring compatibility with standard PCB layouts. REACH status is Unaffected.

200LLE18MEFC10X12.5 (Rubycon): This part also carries Active product status with full manufacturer support. Its electrical and mechanical specifications closely match the original ULD2D180MPD, including identical seated height of 0.571" (14.50 mm) and ripple current at 100 kHz of 214 mA. REACH status is Unaffected. Moisture Sensitivity Level is rated as 1 (Unlimited).

Both parts are ROHS3 compliant and suitable for applications requiring 18 µF, 200 V aluminum electrolytic capacitors in radial through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can EKXF201ELL180MJC5S and 200LLE18MEFC10X12.5 be used interchangeably with ULD2D180MPD?

A: Both parts meet all specified electrical and mechanical parameters. They share identical capacitance (18 µF), voltage rating (200 V), tolerance (±20%), lifetime (15000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (5.00 mm), and case diameter (10.00 mm). Both are through-hole radial can packages suitable for direct PCB mounting.

Q: What is the difference in seated height between the substitutes?

A: The ULD2D180MPD and 200LLE18MEFC10X12.5 both have a maximum seated height of 0.571" (14.50 mm). The EKXF201ELL180MJC5S has a maximum seated height of 0.551" (14.00 mm), which is 0.02" shorter. This difference is within typical PCB layout tolerances and does not affect electrical performance.

Q: Are there differences in ripple current ratings?

A: At 120 Hz, all three parts are rated at 113 mA. At 100 kHz, the EKXF201ELL180MJC5S provides 282.5 mA, while the ULD2D180MPD and 200LLE18MEFC10X12.5 provide 214.7 mA and 214 mA respectively. The higher ripple current in the Chemi-Con part indicates greater thermal performance margin in high-frequency applications.

Q: What is the product status significance?

A: The ULD2D180MPD is classified as Not For New Designs, meaning Nichicon has discontinued active development and support. Both substitute parts carry Active status, indicating current manufacturer support, ongoing availability, and compliance with current industry standards.

Q: Are all parts RoHS compliant?

A: All three parts are ROHS3 compliant, meeting current environmental and hazardous substance restrictions.
