Engineering Selection Recommendations

Nichicon UCY2V330MHD: This substitute provides a voltage rating upgrade from 250 V to 350 V while maintaining identical mechanical dimensions and lead spacing. The extended lifetime of 12000 hours at 105°C exceeds the original specification. Both parts are Nichicon products with Active status and ROHS3 compliance. This substitute is suitable for applications requiring enhanced voltage margin or extended operational life within the same form factor.

Chemi-Con EKXJ351ELL330MK20S: This substitute maintains the 250 V voltage class equivalent through its 350 V rating and matches all mechanical parameters. The component carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. ROHS3 compliance and Active product status align with the original part. This substitute is appropriate for automotive applications or where automotive-grade reliability standards are required.

Frequently Asked Questions (FAQ)

Q: Can UCY2V330MHD be used as a direct replacement for UCS2E330MHD? A: Yes. The UCY2V330MHD maintains identical capacitance (33 µF), tolerance (±20%), and mechanical dimensions. The higher voltage rating (350 V vs. 250 V) and extended lifetime (12000 hrs vs. 10000 hrs) represent performance enhancements compatible with the original application space.

Q: What is the difference between the two substitute parts? A: Both substitutes provide 350 V voltage ratings and identical mechanical form factors. The primary difference is manufacturer: Nichicon UCY2V330MHD offers extended lifetime (12000 hrs), while Chemi-Con EKXJ351ELL330MK20S carries AEC-Q200 automotive qualification. Selection depends on application requirements and manufacturer preference.

Q: Are the lead spacing and mounting dimensions identical across all three parts? A: Yes. All three parts share identical lead spacing (0.197" / 5.00mm), diameter (0.492" / 12.50mm), and maximum seated height (0.846" / 21.50mm). Through-hole radial can packaging is consistent across all variants, ensuring PCB compatibility.

Q: Do all parts meet RoHS compliance requirements? A: Yes. The main part UCS2E330MHD and both substitutes (UCY2V330MHD and EKXJ351ELL330MK20S) are ROHS3 compliant.

Q: Which substitute should be selected for automotive applications? A: The Chemi-Con EKXJ351ELL330MK20S carries AEC-Q200 automotive qualification and is specified for automotive applications. This part is the appropriate selection when automotive-grade reliability standards are required.
