Substitute Part Grouping Explanation

Substitution of the UVZ2A331MHD1TO is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Ripple current ratings: 540 mA @ 120 Hz and 810 mA @ 10 kHz (exact match required)
• Physical dimensions: Lead spacing 5.00 mm, case diameter 12.50 mm, height 27.00 mm (exact match required)
• Mounting configuration: Through-hole radial can package (exact match required)
• Compliance: ROHS3 compliant (exact match required)

The UVY2A331MHD1TO meets all substitution criteria as a parametric equivalent from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the UVZ2A331MHD1TO and UVY2A331MHD1TO carry "Not For New Designs" status, indicating these are legacy components. For applications currently using either part, direct substitution is permissible based on parametric equivalence. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for existing designs. Selection between these two equivalent parts may be based on inventory availability and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the UVY2A331MHD1TO replace the UVZ2A331MHD1TO in existing applications?

A: Yes. Both parts are parametrically equivalent across all critical specifications including capacitance, voltage rating, tolerance, lifetime, temperature range, ripple current ratings, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts share identical dimensions: 12.50 mm case diameter, 5.00 mm lead spacing, and 27.00 mm seated height. They are both radial, through-hole mounted aluminum electrolytic capacitors in can configuration.

Q: What does "Not For New Designs" status mean for these parts?

A: This designation indicates that both the UVZ2A331MHD1TO and UVY2A331MHD1TO are legacy components. While they remain available for existing production and maintenance applications, they should not be selected for new circuit designs. Consultation with the manufacturer regarding current-generation alternatives is recommended for new development.

Q: Are both parts RoHS compliant?

A: Yes. Both the UVZ2A331MHD1TO and UVY2A331MHD1TO are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference between the UVZ and UVY series designations?

A: The series designation (UVZ versus UVY) reflects different product lines within Nichicon's aluminum electrolytic capacitor portfolio. Despite the series difference, these specific part numbers are parametrically equivalent and interchangeable for the specified electrical and mechanical requirements.
