Substitute Part Grouping Explanation

Substitution of the UVY1V331MPD1TD 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)
Package Configuration: Radial, Can with 0.197" (5.00 mm) lead spacing
Physical Dimensions: 0.394" (10.00 mm) diameter, maximum height 0.551" (14.00 mm)
Mounting Type: Through Hole
Operating Temperature Range: -55°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents maintain identical electrical and mechanical specifications, including lifetime rating of 2000 hours at 105°C. These parts are interchangeable without circuit redesign.

Parametric Equivalents meet all critical electrical and mechanical parameters but may differ in lifetime rating (1000 hours at 105°C) or minor dimensional variations within tolerance. These parts are functionally compatible but require evaluation of application-specific lifetime requirements.

Engineering Selection Recommendations

For applications requiring 2000-hour lifetime at 105°C with Active product status:

EEU-HD1V331B (Panasonic) and ECA-1VHG331B (Panasonic) are the preferred selections. Both parts are in Active product status, ROHS3 compliant, and maintain the full 2000-hour lifetime specification. EEU-HD1V331B provides exact dimensional match to the original part. ECA-1VHG331B offers a slightly reduced height (0.531" vs. 0.551") which may provide layout advantages in space-constrained applications.

For applications where 1000-hour lifetime at 105°C is acceptable:

URZ1V331MPD1TD (Nichicon) and EKMG350ETD331MJC5S (Chemi-Con) are suitable alternatives. Both are Active product status and ROHS3 compliant. URZ1V331MPD1TD maintains the Nichicon product line continuity. EKMG350ETD331MJC5S provides cross-manufacturer qualification.

For legacy system maintenance:

UVZ1V331MPD1TD and UKA1V331MPD1TD (both Nichicon) maintain the 2000-hour lifetime specification but are classified as Not For New Designs. These parts are suitable for direct replacement in existing systems where supply is available.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can URZ1V331MPD1TD be used as a direct replacement for UVY1V331MPD1TD?

A: URZ1V331MPD1TD is a parametric equivalent with identical electrical and mechanical specifications except for lifetime rating. It is rated for 1000 hours at 105°C compared to 2000 hours for the original part. It is suitable for applications where the reduced lifetime does not impact system reliability requirements.

Q: What is the difference between ECA-1VHG331B and EEU-HD1V331B?

A: Both parts are manufactured by Panasonic and meet all critical electrical parameters. ECA-1VHG331B has a maximum seated height of 0.531" (14.60 mm), while EEU-HD1V331B is 0.551" (14.00 mm). Both are rated for 2000 hours at 105°C and are in Active product status. The height difference may be relevant for PCB layout constraints.

Q: Are all substitute parts through-hole mounted?

A: Yes. All listed substitute parts are through-hole mounted radial capacitors with 0.197" (5.00 mm) lead spacing, maintaining compatibility with existing PCB designs.

Q: Which substitute part has the longest available inventory?

A: UVZ1V331MPD1TD has 2403 pieces in stock, followed by ECA-1VHG331B with 2638 pieces. Both are suitable for high-volume applications.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

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

A: Parts marked as "Not For New Designs" are legacy products that remain available for existing system support but should not be selected for new circuit designs. Active status parts are recommended for new applications to ensure long-term supply chain continuity.
