Engineering Selection Recommendations

Direct Equivalent (860080574014): The Würth Elektronik WCAP-ATLI series part 860080574014 provides direct functional equivalence with identical electrical specifications and lifetime rating. This part carries Active product status, ensuring continued availability and supply chain stability. Selection of this part maintains design specifications without modification.

Upgraded Alternative (860160574023): The Würth Elektronik WCAP-ATLL series part 860160574023 offers extended operational lifetime (4000 hours at 105°C) while maintaining all other electrical and mechanical parameters. This part also carries Active product status. The marginal height reduction (0.846" versus 0.866") is within typical PCB layout tolerances for through-hole components. This option is suitable for applications requiring enhanced reliability or extended service intervals.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can 860080574014 be used as a direct replacement for UPW1V331MPD6TD?

A: Yes. The 860080574014 matches all critical electrical parameters (330 µF, 35 V, ±20% tolerance) and mechanical specifications (lead spacing, case diameter, through-hole mounting). PCB layout modifications are not required.

Q: What is the difference between 860080574014 and 860160574023?

A: Both parts are electrically and mechanically equivalent. The primary distinction is lifetime rating: 860080574014 is rated for 3000 hours at 105°C, while 860160574023 is rated for 4000 hours at 105°C. The 860160574023 also has a slightly reduced maximum seated height (0.846" versus 0.866"), which does not affect standard through-hole PCB applications.

Q: Are there any height clearance concerns with the substitute parts?

A: The Würth Elektronik substitutes have a maximum seated height of 0.846" (21.50 mm) compared to the original part's 0.866" (22.00 mm). This 0.02" reduction is negligible for typical through-hole applications and does not require PCB redesign.

Q: Do the substitute parts require any circuit modifications?

A: No. Both substitute parts maintain identical capacitance, voltage rating, tolerance, and polarization. Direct pin-for-pin substitution is possible without circuit alterations.

Q: What is the inventory status of these substitute parts?

A: 860080574014 has 1620 pieces in stock; 860160574023 has 1330 pieces in stock. Both are classified as Active products with ongoing availability.
