Substitute Part Grouping Explanation

Substitution eligibility for the UVK1V331MPD is determined by strict adherence to the following parameters: capacitance value (330 µF), voltage rating (35 V), tolerance (±20%), package type (radial can), lead spacing (5.00 mm), physical dimensions (0.394" diameter, 0.551" height maximum), through-hole mounting configuration, and RoHS3 compliance.

Substitute parts are grouped into four categories based on their relationship to the main part:

Upgrade Parts offer enhanced performance characteristics while maintaining full mechanical and electrical compatibility. These include extended lifetime ratings at higher temperatures or improved ripple current handling.

Similar Parts maintain identical electrical specifications and physical dimensions but may differ in series designation or minor performance metrics.

Parametric Equivalents match all critical electrical and mechanical parameters with identical footprint compatibility.

Direct Equivalents are sourced from alternative manufacturers and provide functionally identical performance within the specified parameter envelope.

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

URS1V331MPD (Nichicon) provides the most direct substitution path. It maintains identical physical dimensions (0.394" diameter, 0.551" height), lead spacing (5.00 mm), and electrical specifications (330 µF, 35 V, ±20% tolerance). Critically, URS1V331MPD carries Active product status, ensuring continued availability and manufacturing support, whereas the original UVK1V331MPD is classified as Not For New Designs.

For Enhanced Reliability Requirements:

UHV1V331MPD (Nichicon) offers extended lifetime (6000 hours at 105°C versus 2000 hours at 85°C) while maintaining identical footprint compatibility. This upgrade is suitable for applications requiring improved thermal performance or extended operational life.

For Extended Temperature Range Applications:

UKA1V331MPD (Nichicon) extends the operating temperature range to -55°C to 105°C and provides 2000-hour lifetime at 105°C, accommodating more demanding thermal environments while preserving mechanical compatibility.

For Multi-Manufacturer Sourcing:

35YXJ330M10X12.5 (Rubycon) and 35ZLH330MEFC10X12.5 (Rubycon) provide alternative sourcing from established manufacturers. Both maintain identical physical dimensions and offer superior lifetime ratings (10000 hours at 105°C). 337CKE035M (Cornell Dubilier / Illinois Capacitor) provides North American sourcing with Active product status and 2000-hour lifetime at 105°C.

Mechanical Incompatibility Note:

UKL1V331MHD differs in physical dimensions (0.492" diameter, 0.846" height) and is suitable only for applications where PCB layout permits larger component footprints.

Frequently Asked Questions (FAQ)

Q: Can URS1V331MPD be used as a direct drop-in replacement for UVK1V331MPD?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (35 V), tolerance (±20%), physical dimensions (0.394" diameter, 0.551" height), lead spacing (5.00 mm), and through-hole mounting configuration. URS1V331MPD carries Active product status, making it the preferred long-term replacement.

Q: What is the difference between UHV1V331MPD and URS1V331MPD?

A: Both maintain identical physical dimensions and electrical ratings. UHV1V331MPD offers extended lifetime (6000 hours at 105°C) and higher operating temperature ceiling (105°C maximum) compared to URS1V331MPD (2000 hours at 85°C). Selection depends on thermal environment and required operational life.

Q: Are Rubycon parts (35YXJ330M10X12.5, 35ZLH330MEFC10X12.5) compatible with the original UVK1V331MPD footprint?

A: Yes. Both Rubycon parts maintain identical lead spacing (5.00 mm), diameter (0.394"), and height (0.551"), ensuring PCB compatibility. Both offer superior lifetime ratings (10000 hours at 105°C) and are currently in Active production status.

Q: Why is UKL1V331MHD listed but not recommended as a direct replacement?

A: UKL1V331MHD has different physical dimensions (0.492" diameter, 0.846" height) and larger footprint. It is mechanically incompatible with PCB layouts designed for the original 0.394" diameter, 0.551" height package. Use only if PCB layout accommodates the larger can size.

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

A: Active status indicates the manufacturer continues production and supports the part for new designs. Not For New Designs indicates the part is in end-of-life phase with limited future availability. For new applications or long-term sourcing, select parts with Active status such as URS1V331MPD, 337CKE035M, or Rubycon alternatives.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All parts listed maintain ROHS3 Compliant certification, ensuring compatibility with RoHS3 regulatory requirements.
