Engineering Selection Recommendations

Primary Recommendation: UPA1C331MPD1TA

The UPA1C331MPD1TA is the preferred substitute for new applications and ongoing support. This part maintains all mandatory electrical and mechanical parameters while offering extended lifetime (3000 Hrs @ 105°C versus 2000 Hrs) and Active product status. The UPA series represents Nichicon's current generation for this capacitance and voltage class.

Alternative Recommendation: 860160374020 (Würth Elektronik)

The 860160374020 provides cross-manufacturer compatibility with identical electrical specifications and superior lifetime rating (4000 Hrs @ 105°C). This part is Active and suitable for applications requiring extended operational life or where Würth Elektronik supply chain is preferred.

Secondary Recommendation: UPA1E331MPD1TA

The UPA1E331MPD1TA is suitable where circuit design permits a higher voltage rating (25 V versus 16 V). This part offers improved voltage margin and extended lifetime (3000 Hrs @ 105°C) with Active product status.

Parametric Equivalent: UPS1C331MPD1TD

The UPS1C331MPD1TD provides identical electrical and mechanical specifications with higher inventory availability (14,638 Pcs). This part maintains the same series characteristics and is suitable for direct replacement in existing designs, though it retains "Not For New Designs" status.

Frequently Asked Questions (FAQ)

Q: Can UPA1C331MPD1TA directly replace UPS1C331MPD1TA?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), physical dimensions, and lead spacing. The UPA1C331MPD1TA offers extended lifetime (3000 Hrs versus 2000 Hrs @ 105°C) and Active product status, making it the preferred upgrade path.

Q: What is the difference between UPA1C331MPD1TA and UPA1E331MPD1TA?

A: The primary difference is voltage rating: UPA1C331MPD1TA is rated 16 V, while UPA1E331MPD1TA is rated 25 V. Both share identical capacitance, tolerance, physical dimensions, and lead spacing. The 25 V variant is suitable for circuits where higher voltage margin is beneficial or required.

Q: Can I use 860160374020 (Würth Elektronik) as a substitute?

A: Yes. The 860160374020 matches all mandatory parameters and offers superior lifetime (4000 Hrs @ 105°C). This cross-manufacturer substitute is suitable for applications where extended operational life or Würth Elektronik supply chain preference is applicable.

Q: Why is UPS1C331MPD1TA marked "Not For New Designs"?

A: This designation indicates the part has been superseded in Nichicon's product portfolio. The UPA series represents the current generation. For new designs, UPA1C331MPD1TA is the recommended choice. For legacy system maintenance, UPS1C331MPD1TA remains functionally equivalent to its direct substitutes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 Compliant certification, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of lead spacing and physical dimensions?

A: Lead spacing (0.138" / 4.60 mm) and physical dimensions (0.315" Dia / 8.00 mm, 0.512" Height) determine PCB footprint compatibility. All listed substitutes maintain identical dimensions, ensuring direct mechanical and electrical compatibility without PCB redesign.
