Package configuration: Radial, Can (exact match required)
Lead spacing: 0.138" (4.60 mm) (exact match required)
Case diameter: 0.315" (8.00 mm) (exact match required)
Height (seated max): 0.512" (13.00 mm) (exact match required)
Mounting type: Through Hole (exact match required)

Secondary Substitution Criteria (Voltage Rating):

Direct substitutes: 10 V rated (same voltage class)
Upgrade substitutes: 16 V or 25 V rated (higher voltage rating, backward compatible in 10 V applications)

Tertiary Substitution Criteria (Lifetime & Performance):

Engineering Selection Recommendations

Direct Manufacturer Equivalent (Same Voltage Class): UPJ1A331MPD1TD is a direct equivalent within the Nichicon product line, maintaining 10 V voltage rating and 3000 Hrs lifetime. However, this part shares the Not For New Designs status with the main part. UPM1A331MPD1TD provides parametric equivalence at 10 V with AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability.

Upgrade Substitutes (Higher Voltage Rating): UPA1C331MPD1TD (16 V) and UPA1E331MPD1TD (25 V) are Active status parts from Nichicon's UPA series. Both maintain 330 µF capacitance and 3000 Hrs lifetime while offering higher voltage ratings. These parts are suitable for direct replacement in 10 V applications and provide design margin for voltage transients. UPA1C331MPD1TD and UPA1E331MPD1TD feature lower impedance (90 mOhms) compared to the main part (117 mOhms), improving ripple current performance.

UPW1C331MPD1TD (16 V) maintains the UPW series characteristics with identical impedance to the main part, providing a voltage upgrade path within the same series family.

Cross-Manufacturer Alternatives: Würth Elektronik WCAP-ATLI series (860080374011 at 16 V, 860080274009 at 10 V) and WCAP-ATLL series (860160374020 at 16 V, 860160274017 at 10 V) provide Active status alternatives. The WCAP-ATLL series offers extended lifetime (4000 to 7000 Hrs @ 105°C) for applications requiring enhanced reliability. All Würth Elektronik parts maintain identical mechanical compatibility and RoHS3 compliance.

Compliance Considerations: All listed substitutes maintain ROHS3 compliance and identical mechanical footprint (lead spacing, case diameter, height). Nichicon UPA series parts are REACH Affected; Würth Elektronik parts are REACH Unaffected. Selection should account for supply chain compliance requirements and product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can UPA1C331MPD1TD or UPA1E331MPD1TD be used as direct replacements for UPW1A331MPD1TD? A: Yes. Both parts maintain identical capacitance (330 µF), tolerance (±20%), mechanical dimensions, and lead spacing. The higher voltage ratings (16 V and 25 V respectively) are backward compatible in 10 V applications. Both are Active status parts, addressing the Not For New Designs status of the original part.

Q: What is the difference between UPW1C331MPD1TD and UPA1C331MPD1TD? A: Both are 330 µF, 16 V, 3000 Hrs @ 105°C parts with identical mechanical dimensions. UPW1C331MPD1TD belongs to the UPW series (Not For New Designs) with 117 mOhms impedance. UPA1C331MPD1TD belongs to the UPA series (Active status) with 90 mOhms impedance, offering lower impedance and active product support.

Q: Are Würth Elektronik parts compatible with Nichicon footprints? A: Yes. All listed Würth Elektronik parts (860080374011, 860160274017, 860160374020, 860080274009) maintain identical lead spacing (0.138" / 4.60 mm), case diameter (0.315" / 8.00 mm), and height (0.512" / 13.00 mm), ensuring mechanical and electrical compatibility on existing PCB layouts.

Q: Why does 860160274017 have higher impedance (450 mOhms) than the main part (117 mOhms)? A: 860160274017 is from the WCAP-ATLL series with extended lifetime (7000 Hrs @ 105°C versus 3000 Hrs). The higher impedance reflects different internal construction optimized for extended operational life. This part is suitable for applications where extended reliability is prioritized over low impedance performance.

Q: What is the difference between Cut Tape (CT) and Tape & Box (TB) packaging? A: Both packaging types contain identical electrical components. Cut Tape (CT) is supplied on continuous tape for automated assembly. Tape & Box (TB) is supplied in tape format within a box for manual or semi-automated handling. Electrical and mechanical specifications are identical; packaging selection depends on assembly process requirements.

Q: Can UPM1A331MPD1TD be used in non-automotive applications? A: Yes. UPM1A331MPD1TD meets AEC-Q200 automotive qualification but is electrically and mechanically compatible with general-purpose applications. The automotive qualification provides additional reliability assurance without restricting use in non-automotive designs.

Q: Which substitute offers the best long-term reliability? A: 860160274017 (WCAP-ATLL series) provides the longest rated lifetime at 7000 Hrs @ 105°C, compared to 3000 Hrs for most alternatives. This part is suitable for applications requiring extended operational life or high-reliability environments.
