Equivalent & Substitute Parts for UPA1C331MPD1TA

Part Overview

The UPA1C331MPD1TA is a 330 µF, 16 V aluminum electrolytic capacitor in radial configuration manufactured by Nichicon. This component is classified as Active and suitable for general purpose applications requiring through-hole mounting. The part is specified for 3000 hours of operation at 105°C with an operating temperature range of -55°C to 105°C.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components with improved specifications or compliance status.

Substitute Part Grouping Explanation

Substitution eligibility for the UPA1C331MPD1TA is determined by strict equivalence across the following parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 16 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 3000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Lead Spacing: 0.138" (4.60mm) (exact match required)
Size / Dimension: 0.315" Dia (8.00mm) (exact match required)
Height - Seated (Max): 0.512" (13.00mm) (exact match required)
Mounting Type: Through Hole (exact match required)

All identified substitute parts meet these criteria. Variations in secondary parameters such as impedance, ripple current specifications, and product status do not affect functional substitutability within the defined electrical and mechanical constraints.

Engineering Selection Recommendations

All four parts listed meet the electrical and mechanical substitution criteria. Selection should be based on product status and compliance requirements:

UPA1C331MPD1TA (Primary Part): Active status. Suitable for new designs and ongoing production. Current inventory: 738 units.

UPW1C331MPD1TA and UPW1C331MPD1TD (Nichicon UPW Series): Both marked as Not For New Designs. These parts are suitable only for legacy system maintenance, repair, or replacement in existing applications. UPW1C331MPD1TD offers significantly higher inventory availability (39,750 units) compared to UPW1C331MPD1TA (2,801 units).

860080374011 (Würth Elektronik WCAP-ATLI Series): Active status. Manufactured by an alternative supplier. Suitable for new designs and production applications. Current inventory: 1,782 units. This part provides cross-manufacturer substitution capability.

For new designs, selection between UPA1C331MPD1TA and 860080374011 is based on supplier preference and supply chain strategy. For legacy system support, UPW series parts remain functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can UPW1C331MPD1TA or UPW1C331MPD1TD be used in new product designs?

A: Both UPW series parts carry a "Not For New Designs" status. They are suitable only for replacement in existing applications or legacy system maintenance. New designs should use UPA1C331MPD1TA or 860080374011.

Q: What is the difference between UPW1C331MPD1TA and UPW1C331MPD1TD?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: UPW1C331MPD1TD has 39,750 units in stock compared to 2,801 units for UPW1C331MPD1TA. Both are marked Not For New Designs.

Q: Is 860080374011 a direct replacement for UPA1C331MPD1TA?

A: Yes. The Würth Elektronik part 860080374011 meets all electrical and mechanical substitution criteria. Both parts are Active status and suitable for new designs. This represents a cross-manufacturer equivalent.

Q: Are there any differences in ripple current or impedance specifications?

A: Secondary performance parameters vary between parts. UPA1C331MPD1TA specifies 409.5 mA ripple current at 120 Hz with 90 mOhms impedance. UPW series parts specify 360.75 mA at 120 Hz with 117 mOhms impedance. The Würth part specifies 740 mA at 100 kHz with 80 mOhms impedance. These variations do not affect substitutability within the defined electrical and mechanical constraints.
