Substitute Part Grouping Explanation

Substitution for the UPW1E331MPD1TD is determined by strict equivalence in the following electrical and mechanical parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 25 V (exact match required)
Tolerance: ±20% (exact match required)
Package configuration: Radial, Can (exact match required)
Mounting type: Through Hole (exact match required)
Physical dimensions: 0.394" Dia × 0.551" Height, 5.00 mm lead spacing (exact match required)
Operating temperature range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Two substitute parts from Würth Elektronik meet these criteria: 860160475020 (WCAP-ATLL series) and 860080475013 (WCAP-ATLI series). Both maintain identical electrical specifications and physical form factors, ensuring direct compatibility in PCB layouts and circuit designs.

Engineering Selection Recommendations

Both Würth Elektronik substitutes are suitable replacements based on compliance and product status criteria:

860160475020 (WCAP-ATLL series) is an Active product with extended lifetime rating of 7000 hours at 105°C, compared to the original 5000 hours. This part offers improved reliability margins in thermal stress conditions while maintaining all electrical and mechanical specifications.

860080475013 (WCAP-ATLI series) is an Active product with matching 5000-hour lifetime at 105°C. This part provides equivalent performance characteristics with lower impedance (54 mOhms) and higher ripple current handling at 100 kHz (1.01 A).

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection between the two should be based on application-specific requirements for thermal endurance and ripple current performance.

Frequently Asked Questions (FAQ)

Q: Can 860160475020 or 860080475013 be used as direct replacements for UPW1E331MPD1TD?

A: Yes. Both parts are direct substitutes. They share identical capacitance (330 µF), voltage rating (25 V), tolerance (±20%), physical dimensions, lead spacing, and mounting configuration. PCB layouts and circuit designs require no modification.

Q: What is the difference between the two Würth Elektronik substitutes?

A: The primary differences are lifetime rating and impedance characteristics. 860160475020 offers 7000 hours at 105°C versus 5000 hours for 860080475013. 860080475013 has lower impedance (54 mOhms vs. 240 mOhms) and higher ripple current capacity at 100 kHz (1.01 A vs. 924 mA).

Q: Are these parts compatible with existing PCB designs?

A: Yes. All three parts maintain identical lead spacing (5.00 mm), diameter (10.00 mm), and height (14.00 mm). No PCB layout modifications are required.

Q: Do the substitute parts meet current compliance standards?

A: Yes. Both 860160475020 and 860080475013 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the original UPW1E331MPD1TD marked as Not For New Designs?

A: This designation indicates the part has been superseded in Nichicon's active product portfolio. The Würth Elektronik alternatives (both Active status) are recommended for new designs while the original remains available for legacy system support and maintenance applications.
