Substitute Part Grouping Explanation

Substitution eligibility for the UVP1H331MHD1TN is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime Rating: 2000 Hrs @ 85°C (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Polarization: Bi-Polar (exact match required)
• Package Configuration: Radial, Can (exact match required)
• Mounting Type: Through Hole (exact match required)
• Lead Spacing: 0.295" (7.50 mm) (exact match required)
• Physical Dimensions: 0.630" Dia × 1.063" Height (exact match required)

The ECE-A1HN331UB from Panasonic Electronic Components meets all critical substitution criteria and is classified as a parametric equivalent.

Engineering Selection Recommendations

The ECE-A1HN331UB is the qualified substitute for the UVP1H331MHD1TN. Selection between these parts should be based on the following factors:

Product Status: The UVP1H331MHD1TN carries "Not For New Designs" status, while the ECE-A1HN331UB is classified as "Active." For new circuit designs and long-term production continuity, the Panasonic ECE-A1HN331UB is the appropriate choice.

Compliance & Certifications: Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and export purposes.

Ripple Current Performance: The UVP1H331MHD1TN provides higher ripple current ratings (650 mA @ 120 Hz, 975 mA @ 10 kHz) compared to the ECE-A1HN331UB (450 mA @ 120 Hz, 765 mA @ 10 kHz). Applications requiring maximum ripple current handling should retain the original Nichicon part if available; otherwise, circuit design must account for the reduced ripple current capability of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1HN331UB be used as a direct replacement for the UVP1H331MHD1TN?

A: Yes. Both parts share identical electrical specifications (330 µF, 50 V, ±20% tolerance, 2000 Hrs @ 85°C), identical physical dimensions, lead spacing, and mounting configuration. Direct PCB substitution is mechanically and electrically compatible.

Q: What is the difference in ripple current handling between these parts?

A: The UVP1H331MHD1TN supports 650 mA @ 120 Hz and 975 mA @ 10 kHz. The ECE-A1HN331UB supports 450 mA @ 120 Hz and 765 mA @ 10 kHz. Applications operating near maximum ripple current limits should evaluate the reduced capability of the substitute.

Q: Why is the UVP1H331MHD1TN marked "Not For New Designs"?

A: This status indicates the part is in mature or end-of-life phase. Nichicon recommends the ECE-A1HN331UB or equivalent active alternatives for new circuit development to ensure long-term supply chain stability.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications, and are suitable for equivalent regulatory and export compliance purposes.

Q: Will the ECE-A1HN331UB fit the same PCB footprint?

A: Yes. Both parts have identical lead spacing (0.295" / 7.50 mm), case diameter (0.630" / 16.00 mm), and seated height (1.063" / 27.00 mm). No PCB layout modifications are required.
