Substitute Part Grouping Explanation

Substitution for the UVY1J331MPD1TD is determined by strict equivalence across the following parameters:

Capacitance Value: 330 µF (exact match required)
Voltage Rating: 63 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Configuration: Radial, Can (exact match required)
Lead Spacing: 0.197" (5.00mm) (exact match required)
Physical Dimensions: 0.394" Dia × 0.866" Height (exact match required)
Mounting Type: Through Hole (exact match required)
Compliance: ROHS3 Compliant (exact match required)

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the UVY1J331MPD1TD.

Engineering Selection Recommendations

UVZ1J331MPD1TD (Nichicon): This part is a parametric equivalent to the UVY1J331MPD1TD with identical electrical and mechanical specifications. Both parts carry "Not For New Designs" status. Selection between these two Nichicon variants should be based on inventory availability and lead time requirements. Current inventory shows 17,276 units of the UVZ1J331MPD1TD available.

ECA-1JHG331B (Panasonic Electronic Components): This part meets all electrical and mechanical substitution criteria and carries an "Active" product status, indicating ongoing manufacturer support and availability. The ECA-1JHG331B is suitable for applications requiring long-term component availability and supply chain continuity. Current inventory shows 1,368 units available.

For new designs or applications requiring extended component lifecycle support, the ECA-1JHG331B is the preferred selection due to its active product status. For existing designs currently using the UVY1J331MPD1TD, both the UVZ1J331MPD1TD and ECA-1JHG331B provide direct electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the UVZ1J331MPD1TD be used as a direct replacement for the UVY1J331MPD1TD?

A: Yes. The UVZ1J331MPD1TD is a parametric equivalent with identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lifetime rating (2000 Hrs @ 105°C), operating temperature range (-55°C ~ 105°C), and physical dimensions. Both parts are through-hole mounted radial cans with 5.00mm lead spacing and 10.00mm diameter. No circuit modifications are required.

Q: Is the ECA-1JHG331B compatible with the UVY1J331MPD1TD in existing applications?

A: Yes. The ECA-1JHG331B meets all electrical and mechanical specifications of the UVY1J331MPD1TD. It shares identical capacitance, voltage rating, tolerance, lifetime rating, operating temperature range, lead spacing, and physical dimensions. The component can be substituted without circuit redesign or PCB layout modifications.

Q: What is the significance of the "Not For New Designs" status on the UVY1J331MPD1TD and UVZ1J331MPD1TD?

A: This status indicates that the manufacturer is not recommending these parts for new product designs. However, they remain available for existing applications and maintenance. The ECA-1JHG331B carries an "Active" status, indicating it is recommended for new designs and has ongoing manufacturer support.

Q: Are there any differences in ripple current ratings between these parts?

A: The UVY1J331MPD1TD and UVZ1J331MPD1TD both specify 510 mA @ 120 Hz and 765 mA @ 10 kHz. The ECA-1JHG331B specifies 510 mA @ 120 Hz and 765 mA @ 100 kHz. All parts meet the same low-frequency ripple current specification. The high-frequency ripple current specification differs only in the test frequency, not the current rating value.

Q: Do all three parts have the same compliance certifications?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry the same ECCN (EAR99) and HTSUS (8532.22.0020) classifications. Moisture Sensitivity Level is Not Applicable for all three parts.

Q: What is the lead spacing, and why is it important for substitution?

A: All three parts have a lead spacing of 0.197" (5.00mm). This dimension is critical for PCB compatibility. Identical lead spacing ensures that the substitute part will fit existing PCB footprints without modification.
