Substitute Part Grouping Explanation

Substitution eligibility for the UVP1V331MHD1TO is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 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)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Case diameter: 0.492" (12.50 mm) (exact match required)
• Height: 0.866" (22.00 mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package configuration: Radial, Can (exact match required)

The ECE-A1VN331UB from Panasonic Electronic Components meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ECE-A1VN331UB is a direct parametric equivalent suitable for applications currently using the UVP1V331MHD1TO. Both components are ROHS3 compliant and carry identical ECCN and HTSUS classifications, ensuring regulatory and compliance alignment.

The Panasonic ECE-A1VN331UB carries an "Active" product status, providing assurance of continued availability and manufacturing support, whereas the Nichicon UVP series is designated "Not For New Designs." This status difference makes the Panasonic alternative the preferred choice for sustained production requirements.

Ripple current performance differs slightly between the two parts: the Nichicon UVP1V331MHD1TO delivers 505 mA at 120 Hz and 757.5 mA at 10 kHz, while the Panasonic ECE-A1VN331UB provides 450 mA at 120 Hz and 765 mA at 10 kHz. These variations remain within acceptable operational margins for general-purpose filtering applications where the specified electrical parameters are met.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1VN331UB be used as a direct replacement for the UVP1V331MHD1TO?

A: Yes. Both components share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), lifetime rating (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), and physical dimensions. The through-hole radial configuration and lead spacing are identical, enabling direct PCB mounting compatibility.

Q: What is the significance of the "Not For New Designs" status on the Nichicon part?

A: This designation indicates that Nichicon has discontinued active development and promotion of the UVP series for new applications. The Panasonic ECE-A1VN331UB, with its "Active" status, represents the recommended path forward for sustained production and future design iterations.

Q: Are there differences in ripple current handling between these two parts?

A: Minor differences exist in ripple current specifications. The Nichicon UVP1V331MHD1TO is rated for 505 mA at 120 Hz and 757.5 mA at 10 kHz, while the Panasonic ECE-A1VN331UB is rated for 450 mA at 120 Hz and 765 mA at 10 kHz. For general-purpose applications, both ratings satisfy standard filtering requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the UVP1V331MHD1TO and ECE-A1VN331UB are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8532.22.0020), ensuring equivalent regulatory standing.

Q: What inventory considerations should be evaluated?

A: The Nichicon UVP1V331MHD1TO has 727 pieces in stock, while the Panasonic ECE-A1VN331UB has 997 pieces available. Given the "Not For New Designs" status of the Nichicon part, the Panasonic alternative offers greater assurance of long-term supply continuity.
