Substitute Part Grouping Explanation

Substitution of the UVP1C331MPD1TD is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Bi-Polar (exact match required)
• Package configuration: Radial, Can through-hole (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Case diameter: 0.394" (10.00 mm) (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Lifetime rating: 2000 Hrs @ 85°C (minimum requirement)

The substitute part ECE-A1CN331UB from Panasonic Electronic Components meets all critical electrical and mechanical parameters for direct substitution in applications currently using the UVP1C331MPD1TD.

Parameter Comparison

Engineering Selection Recommendations

The ECE-A1CN331UB from Panasonic Electronic Components is a direct electrical and mechanical equivalent to the UVP1C331MPD1TD. Both components are ROHS3 compliant and operate within identical temperature ranges and voltage specifications.

The Panasonic substitute offers the advantage of Active product status, ensuring continued availability and manufacturer support. The height difference of 0.020" (0.50 mm) is within typical PCB layout tolerances for through-hole radial capacitors and does not present a functional constraint.

The ripple current specification at 120 Hz is lower in the Panasonic part (330 mA vs. 375 mA). Applications requiring the full ripple current capacity of the original Nichicon part should evaluate this parameter against actual circuit demands before substitution.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1CN331UB replace the UVP1C331MPD1TD in existing designs?

A: Yes. Both parts share identical capacitance, voltage rating, tolerance, polarization, lead spacing, and case diameter. The mechanical height difference of 0.020" is within standard PCB layout tolerances for radial through-hole capacitors.

Q: What is the significance of the product status difference?

A: The UVP1C331MPD1TD is marked Not For New Designs, indicating Nichicon has discontinued active development of this line. The ECE-A1CN331UB maintains Active status from Panasonic, providing assurance of continued supply and manufacturer support.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The Nichicon part is REACH Affected; the Panasonic part is REACH Unaffected. Compliance requirements should be evaluated based on end-use application and regional regulations.

Q: Does the lower ripple current rating of the Panasonic part affect compatibility?

A: The ripple current specification indicates the maximum AC current the capacitor can handle at specified frequencies. The Panasonic part rates 330 mA at 120 Hz compared to 375 mA for the Nichicon part. Substitution is appropriate only if the actual circuit ripple current does not exceed the Panasonic specification.

Q: Are the lead spacing and case dimensions identical?

A: Yes. Both parts feature 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) case diameter, ensuring direct PCB footprint compatibility.
