Engineering Selection Recommendations

UPA1E331MPD1TA is the primary recommended substitute. It maintains all electrical and mechanical compatibility with the UVY1E331MPD1TA while offering Active product status and extended lifetime rating (3000 Hrs @ 105°C versus 1000 Hrs). This part is ROHS3 compliant and REACH Affected. Selection of this part is appropriate for new procurement and replacement applications.

UVY1E331MPD1TD provides parametric equivalence with identical electrical specifications and mechanical form factor. As a Nichicon product within the same UVY series, it maintains REACH Unaffected status. This part is classified as Not For New Designs and is suitable for direct replacement in legacy applications where exact series continuity is required.

EKMG250ETD331MHB5D is a Chemi-Con alternative that meets all critical electrical and mechanical parameters. It is Active product status and ROHS3 compliant with REACH Unaffected designation. This part offers higher ripple current capability at high frequency (465 mA @ 100 kHz) and is suitable for applications requiring cross-manufacturer sourcing or supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can UPA1E331MPD1TA be used as a direct replacement for UVY1E331MPD1TA?

A: Yes. UPA1E331MPD1TA matches all critical electrical parameters (330 µF, 25 V, ±20% tolerance) and mechanical specifications (lead spacing, physical dimensions, through-hole mounting). The extended lifetime (3000 Hrs @ 105°C) and Active product status make it a suitable direct replacement.

Q: What is the difference between UVY1E331MPD1TD and UVY1E331MPD1TA?

A: Both parts are identical in electrical and mechanical specifications. The difference is in the packaging designation (TD versus TA) and inventory availability. Both are classified as Not For New Designs.

Q: Can EKMG250ETD331MHB5D from Chemi-Con replace the Nichicon UVY1E331MPD1TA?

A: Yes. EKMG250ETD331MHB5D meets all critical electrical and mechanical parameters. The primary differences are manufacturer origin and packaging format (Tape & Box versus Cut Tape). The Chemi-Con part offers higher ripple current at high frequency.

Q: Are there any compliance differences between these substitute parts?

A: All substitute parts are ROHS3 compliant. UPA1E331MPD1TA is REACH Affected, while UVY1E331MPD1TD and EKMG250ETD331MHB5D are REACH Unaffected. Compliance requirements should be verified against your specific application and regional regulations.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer has superseded the part in their product line. For new designs, Active status parts such as UPA1E331MPD1TA or EKMG250ETD331MHB5D are preferred. For legacy system maintenance and repairs, Not For New Designs parts remain valid substitutes.

Q: Do these parts have different ripple current ratings?

A: Yes. Ripple current ratings vary among the substitutes. UPA1E331MPD1TA offers higher ripple current at low frequency (409.5 mA @ 120 Hz) compared to UVY1E331MPD1TA (275 mA @ 120 Hz). EKMG250ETD331MHB5D provides the highest ripple current at high frequency (465 mA @ 100 kHz). Selection should be based on your circuit's ripple current requirements.
