Substitute Part Grouping Explanation

Substitution of the UVR1C331MPD is determined by the following criteria:

Primary Matching Parameters:

Capacitance: 330 µF (exact match required)
Voltage Rating: 16 V (exact match required for direct substitution)
Package Type: Radial, Can (physical compatibility)
Lead Spacing: 0.138" (4.60 mm) (PCB footprint compatibility)
Case Diameter: 0.315" (8.00 mm) (board space compatibility)
Height: 0.512" (13.00 mm) (clearance compatibility)
Mounting Type: Through Hole (assembly method compatibility)

Secondary Optimization Parameters:

Lifetime @ Temperature (improved thermal endurance)
Operating Temperature Range (extended limits)
Ripple Current Ratings (performance headroom)
Product Status (Active vs. Not For New Designs)
Impedance (electrical performance)

Substitute parts maintain identical mechanical dimensions and electrical ratings while offering improved reliability characteristics, extended temperature operating ranges, or active product status.

Engineering Selection Recommendations

For Active Product Status (Recommended for New Designs):

UPA1C331MPD is the only Active product in the 16 V, 330 µF category. It provides 3000 hours lifetime at 105°C, extended operating temperature range (-55°C to 105°C), and REACH Affected compliance. This part is suitable for new design implementations.

For Extended Thermal Performance:

UHV1C331MPD offers the longest service life at 6000 hours @ 105°C with the lowest impedance (59 mOhms) among 16 V substitutes. Operating temperature extends to 105°C maximum. Suitable for applications requiring maximum reliability and thermal stability.

For Improved Temperature Range:

UKA1C331MPD and UPS1C331MPD extend the lower operating limit to -55°C, compared to the original -40°C specification. Both maintain 2000 hours lifetime at 105°C. UKA1C331MPD is designated for audio applications.

For Mechanical and Electrical Compatibility:

All listed 16 V substitutes maintain identical physical dimensions (0.315" diameter, 0.512" height, 0.138" lead spacing) and through-hole mounting configuration, ensuring direct PCB footprint compatibility.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance. UPA1C331MPD, UHD1C331MPD, UHV1C331MPD, and UPA1E331MPD are REACH Affected; UVR1C331MPD, UKA1C331MPD, UKA1E331MPD, UVK1E331MPD, and UVK1C331MED are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can UPA1C331MPD directly replace UVR1C331MPD? A: Yes. Both parts share identical capacitance (330 µF), voltage rating (16 V), tolerance (±20%), and physical dimensions (0.315" diameter, 0.512" height, 0.138" lead spacing). UPA1C331MPD offers improved reliability with 3000 hours @ 105°C versus 2000 hours @ 85°C, and Active product status.

Q: What is the difference between UHD1C331MPD and UHV1C331MPD? A: Both are 330 µF, 16 V radial capacitors with identical physical dimensions. UHV1C331MPD provides extended lifetime (6000 hours @ 105°C versus 3000 hours @ 105°C) and lower impedance (59 mOhms versus 72 mOhms). UHD1C331MPD offers higher ripple current capacity (532 mA @ 120 Hz versus 415 mA @ 120 Hz).

Q: Are 25 V rated parts (UHV1E331MPD, UKA1E331MPD, UPA1E331MPD, UVK1E331MPD) compatible with 16 V circuit requirements? A: No. These parts are rated for 25 V and are not direct substitutes for 16 V applications. They maintain the same physical package but have different electrical ratings. Use only if circuit design permits higher voltage rating.

Q: What does "Not For New Designs" status mean? A: This designation indicates the part is in mature or declining production phase. While available in inventory, Nichicon recommends using Active status parts (such as UPA1C331MPD) for new circuit designs to ensure long-term supply continuity and support.

Q: Does UVK1C331MED have different physical dimensions? A: Yes. UVK1C331MED has a smaller case diameter (0.248" versus 0.315") and reduced lead spacing (0.098" versus 0.138"), making it incompatible with UVR1C331MPD PCB footprints despite matching capacitance and voltage ratings.

Q: Which substitute offers the best thermal performance? A: UHV1C331MPD provides the longest service life at 6000 hours @ 105°C with the lowest impedance (59 mOhms), making it optimal for applications requiring maximum thermal stability and reliability.
